Wouldn’t you like to know everything about resveratrol, but you aren’t sure where to start? Your journey has led you to the perfect place. Today, we are answering all your questions. 

Let’s start with the main one:

What is Resveratrol?

Resveratrol is an antioxidant originating from plants and belongs to the stilbene group. Stilbenes are one of the four major classes of polyphenols, compounds that have attracted a lot of attention in recent years and are the focus of a vast number of scientific studies. Resveratrol is responsible not only for the enormous amount of dust that rises up behind its specific structure but also for the effects it causes in the human body.

In plants, this exceptional compound has a protective role. It protects plants from unwanted external influences, such as pollution, UV rays, and infections. In terms of human health, resveratrol is believed to help maintain heart and eye health, control diabetes and insulin resistance, and accelerate weight loss. However, before we continue, we need to explain the data about this compound. Namely, currently, there is not enough scientific evidence of the benefits of resveratrol. All benefits should be taken with a grain of salt.

Resveratrol Sources

When it comes to sources of resveratrol, one of the most famous facts is its association with grapes and red wine. Grapes, particularly red and purple varieties, have a high concentration of resveratrol in their skins. Berries, such as blueberries and cranberries, also contain significant amounts of this compound, contributing to their antioxidant properties. One of the tasteful sources is also peanuts. 

Fun fact: Did you know that resveratrol gained initial recognition due to its abundant presence in red wine? This discovery led to the “French Paradox”, an observation that despite a diet rich in fats, the French population has a relatively low rate of cardiovascular diseases. This paradox sparked curiosity about the potential health benefits of this noteworthy compound.

Potential Benefits of Resveratrol for Human Health

While resveratrol is in the midst of scientific studies, it has shown significant clinical benefits in vitro and in animals.

Anti-Aging Effect

As we age, our cells’ biological functions gradually decline, and we become more susceptible to diseases. Aging often leads to the development of cardiovascular diseases, cancer, and type 2 diabetes, as well as other related conditions and diseases. Resveratrol is believed to reduce the negative effects of aging through multiple mechanisms, including regulation of oxidative stress, metabolism, and the activation of sirtuins, so-called longevity genes. Animal studies have shown that resveratrol can slow down the cellular processes that lead to aging and extend lifespan.

Eye Health Support

All cells in the body age in the same way, including eye cells. The most common eye diseases associated with aging are cataracts, diabetic neuropathy, age-related macular degeneration, and glaucoma. Thanks to its antioxidant and anti-inflammatory properties, resveratrol may slow down the development and progression of the diseases mentioned. Other than that, its capacity to enhance blood flow and vascular function could contribute to maintaining proper circulation within the eyes, supporting their vital functions.

Brain Protection

Cognitive performance declines as we age, increasing the risk of neurodegenerative diseases. Resveratrol is believed to slow down these processes through several mechanisms:

• by neutralizing free radicals, which are the main cause of damaged neurons 
• by improving cerebrovascular blood flow
• by activating sirtuins, which are responsible for the reaction of cells to stress
• by stimulating the development of proteins that are crucial for the growth and maintenance of neurons
• by suppressing inflammation, which can disrupt brain function and lead to a decline in cognitive abilities.

The protective effects of resveratrol on brain health are attributed to its influence on these interconnected pathways.

Cardiovascular Health

Cardiovascular diseases, which encompass a wide range of conditions, have a profound impact on global health and are the primary cause of mortality worldwide. Oxidative stress plays a vital role in the development of these diseases. It contributes to the formation of atherosclerotic plaques and the pathological thickening of arterial walls, as well as cardiac hypertrophy, fibrosis, and cardiac insufficiency.

Through its antioxidant properties, resveratrol may slow down the progression of cardiovascular diseases. It also promotes vasodilation, which affects the regulation of blood pressure and the function of blood vessels. Interestingly, resveratrol can induce autophagy, a cellular process that involves the recycling of cellular components. Autophagy plays a crucial role in cellular renewal and energy production.

Blood Sugar Management

Certain studies show the effect of resveratrol on blood sugar control through complex mechanisms. Through activating the enzyme AMPK, it increases cell sensitivity to insulin. Besides, it accelerates carbohydrate digestion after meals. These findings imply that it could be extremely beneficial in controlling conditions such as insulin resistance and diabetes.

Inflammation Control

Inflammation is a complex biological process that occurs as a body reaction to inflammatory agents and foreign substances. Resveratrol’s impact on inflammation control entails a few mechanisms. One key mechanism by which resveratrol exerts its effects is through the inhibition of the protein complex NF-κB, a central mediator of inflammatory responses. That is how it attenuates the expression of pro-inflammatory cytokines and enzymes. This modulation suppresses immune-mediated inflammation, offering relief for conditions like arthritis and joint pain.

Weight Loss Assistance

In-vitro and animal studies show remarkable weight control effects of resveratrol. It achieves these beneficial effects in several ways: 

Firstly, it enhances the insulin sensitivity of cells, as mentioned earlier, thereby influencing the regulation of appetite. It also activates sirtuins, which increase the function of mitochondria, cell organelles responsible for energy production. Resveratrol affects the function of adipocytes by slowing down their deposition and accelerating their decomposition in fat tissue. Lastly, resveratrol increases fat oxidation, allowing the body to use fat as an energy source.

Resveratrol Benefits for Skin 

Resveratrol is gaining traction in the fields of medicine and dermatology. Its unique ability to penetrate the skin barrier and stimulate the production of collagen types 1, 2, and 3 has made it a popular dermatological choice. The antioxidant properties of this compound protect cells from the oxidative damage caused by UV radiation. These combined effects position resveratrol as a promising agent for maintaining healthy, youthful skin.

Who Should Avoid Resveratrol?

There is also no official data on the effects of supplementation on pregnancy and lactation, so it is not recommended during these periods. The use of resveratrol supplements is also not advised for people who have bleeding disorders or are preparing for surgery. 

What Not to Use With Resveratrol?

When it comes to drug interactions, resveratrol should not be used together with anticoagulants, antidepressants, antiviral and antifungal medicines, and supplements like St. John’s wort, garlic, and Ginkgo biloba.

To Conclude

Resveratrol is a polyphenol that has exceptional antioxidant and anti-inflammatory properties. It is known for its potential benefits in maintaining the health of the heart, brain, eyes, joints, insulin control, and body weight.

However, as with all polyphenols, there is a lack of scientific research on humans to confirm their effects on human health. While we wait for these results, we can increase our intake of this valuable compound through food or dietary supplements.

FAQ

How much resveratrol should I take?     

Resveratrol supplements come in different dosages. The results of animal studies indicate that doses up to 2 grams per day are safe.

Is it OK to take resveratrol every day?

It is safe to take resveratrol every day from natural sources. In terms of supplementation, taking a break after three months of use is recommended.

Is resveratrol toxic to the liver?

Research on its impact on the liver is mixed. Some studies suggest that resveratrol might have protective effects on the liver, including potential benefits for reducing fatty liver disease and inflammation. On the other hand, there have been isolated cases of liver toxicity associated with extremely high doses of resveratrol supplements in animal studies.

As with any dietary supplement, moderation is important. If you have preexisting liver conditions or if you are considering high-dose resveratrol supplementation, consult a healthcare professional.

Welcome to the story of urolithin A, a bioactive compound discovered 40 years ago. Urolithin A’s complex molecular mechanisms and diverse physiological effects have made it a focus of nutraceutical and longevity research.

In order to understand this compound better, let us first define it in more detail.

Exactly What is Urolithin A?

In simple terms, urolithin A is a postbiotic compound that results from the metabolism of ellagitannins in the colon microbiome. Ellagitannins are polyphenolic compounds found in several fruits and nuts. The most famous sources of urolithin A are berries like pomegranates, strawberries, and raspberries.

After consumption, ellagitannins are metabolized in the human digestive system, resulting in the formation of urolithin A as one of the primary metabolites. Only three bacteria that belong to the genus Gordonibacter have the ability to produce urolithin A.

The production of this longevity molecule varies from person to person. Some individuals lack the necessary bacteria to produce it, while others with them may still not produce enough. The only way to get enough urolithin A is through supplementation. However, before discussing that further, let’s explore the potential health benefits.

Urolithin a Benefits

An increasing number of scientists are interested in urolithin A due to its potential health-promoting properties, particularly in relation to cellular health, mitochondrial function, and anti-aging effects. Research suggests that urolithin A plays a role in activating cellular processes such as autophagy, which is involved in cellular cleansing and renewal, as well as influencing mitochondrial biogenesis, the process of generating new mitochondria within cells. These mechanisms have led to investigations into its possible benefits in combating age-related diseases and promoting overall well-being.

Take a look at how this incredible compound affects the human body.

Cellular Health Support

Mitochondria are cellular organelles responsible for energy production and cellular metabolism. By stimulating mitophagy (the process of breaking down damaged mitochondria), urolithin A restores mitochondria and improves mitochondrial respiratory capacity. Other than that, it stimulates autophagy, the metabolic process of recycling damaged cell components. In those processes, energy is released and cells are renewed. This prevents the accumulation of harmful substances that lead to cell aging.

Anti-Inflammatory Effects

The body’s immune response occurs as a result of the body’s reaction to an antigen (most often a microorganism from the external environment). However, this response can also happen as a reaction to self-antigens or transplants. In this case, we are talking about a harmful immune response that is associated with aging and the onset of many diseases. Urolithin A slows down the production of pro-inflammatory molecules and thus affects the weakening of the harmful immune response.

Potential Anti-Aging Function

Animal studies have shown the strong anti-aging potential of this exceptional compound. Urolithin A increases the production of collagen type 1 while reducing intracellular reactive oxygen species. In addition, the processes of degradation of waste materials in cells via mitophagy and autophagy further support these findings.

Muscle Health Impact

According to several studies, urolithin A enhances muscle mobility and improves the structure of muscle fibers by reducing the effects of muscle degradation caused by aging. How exactly does it affect muscles? 

The first mechanism is the effect on mitochondria, which results in improved energy production, allowing muscles to function optimally and efficiently. Another process is the regulation of protein turnover in muscles, which are their primary building blocks. Protein turnover is the balance between protein breakdown and synthesis within muscle cells. In this way, urolithin A helps to preserve muscle mass, which is especially important in the aging process and other conditions that cause muscle degeneration.

Cardiovascular Health

In a couple of studies, urolithin A has demonstrated powerful effects on cardiovascular health. It exerts beneficial impacts through antioxidant activity, improving myocardial contractions, reducing plasma lipid levels and aortic lesions, and supporting blood vessel function. These mechanisms collectively suggest that urolithin A might contribute to the prevention or mitigation of cardiovascular diseases such as cardiac ischemia and atherosclerosis. However, further studies are needed to better understand the precise extent and specific mechanisms of its impact on cardiovascular health.

Neuroprotective Role

It is believed that urolithin A has a positive effect on the preservation of nervous system function (based on studies conducted on animals). These data indicate the possibility of protection against ischemic stroke and multiple sclerosis. Urolithin A achieves those effects by improving the function of neurons. Due to the breakdown of toxic substances in neurons, nerve cells survive longer, and neurogenesis (the process of creating new neurons) occurs. This affects improvements in associative memory and influences longer memory.

Spine and Joint Health

Numerous animal studies have demonstrated the remarkable effects of urolithin A on spinal cord and joint diseases. 

In the aging process, the intervertebral discs in the spinal column degenerate. Urolithin A helps to alleviate these changes by narrowing the disc of the intervertebral space. In addition, its effect on collagen production alleviates such damage. The second joint disease in which urolithin A activity has been observed is osteoarthritis. This longevity compound was found to improve the cartilage structure of the knee joint, contributing to pain relief.

Weight Control Assistance

The effects of urolithin A on cellular processes and fat and glucose metabolism suggest that this compound may be beneficial for weight loss. 

Experiments on mice have shown that urolithin A:

• Increases the sensitivity of cells to insulin, which directly affects the regulation of body weight;
• Increases the oxidation of fatty acids, which reduces the accumulation of lipids in adipose tissue;
• Restores the antioxidant capacity of the liver;
• Increases the excretion of fat from the body;
• Inhibits the production of new fat cells.

Other Urolithin A Benefits

Apart from these findings, it is believed to be beneficial for the following conditions as well:

• Inflammatory intestinal diseases
• Acute kidney injury
• Metabolic dysfunctions (dyslipidemia and glucose intolerance)

How to Choose the Best Urolithin A Supplement?

Have you heard about quercetin but are not sure if you know everything you are interested in? You are in the right place! Welcome to another exciting journey. This time, we take you to the interesting world of quercetin. 

Let’s begin with the most vital question:

What is Quercetin?

Quercetin is a natural plant pigment classified as a flavonoid that belongs to a larger group of compounds known as polyphenols. As a flavonoid, it plays a crucial role in supporting the plants’ defense mechanisms, helping them combat environmental stressors. Beyond its botanical functions, quercetin has garnered significant attention for its potential health benefits for humans. Recognized for its antioxidant and anti-inflammatory properties, quercetin is believed to contribute to overall well-being and has been studied for its potential role in supporting immune health, cardiovascular function, cognitive performance, and more.

As a flavonoid, quercetin cannot be synthesized in the human body. It has a distinct yellow color and exhibits limited solubility in hot water while demonstrating appreciable solubility in alcohol and lipids. Conversely, it remains insoluble in cold water. These characteristics contribute to the unique properties and behavior of quercetin within various biological and chemical systems.

However, the health benefits of quercetin for human health are currently being investigated, and the available evidence for these claims is currently insufficient. Our current understanding of the potential health benefits of quercetin is limited and requires further study and analysis.

Potential Health Benefits of Quercetin

While its health benefits are still heavily under research, animal and in vitro studies have shown promising results in controlling various health conditions and diseases. 

Now, let’s dive deeper into each potential advantage:

Antioxidant Properties

Quercetin’s antioxidant properties are attributed to its ability to counteract the damaging effects of free radicals. Free radicals are highly reactive molecules that are naturally generated in the body as a result of various metabolic processes and external factors like pollution, UV radiation, and stress. The excessive presence of free radicals leads to oxidative stress, a condition associated with the development of chronic diseases and the aging process.

In addition to its direct scavenging of free radicals, quercetin also supports the body’s own antioxidant defense system. It helps stimulate the production of enzymes that play a crucial role in neutralizing free radicals, thereby enhancing the overall body’s capacity to manage oxidative stress. This dual mechanism of action highlights the potential of quercetin as a valuable agent in combating the detrimental effects of free radicals and maintaining cellular homeostasis.

Anti-Inflammatory Effects

The anti-inflammatory properties of quercetin are related to its ability to modulate the body’s immune response and reduce the production of inflammatory molecules. Inflammation is a natural response of the immune system to various stimuli, such as injury, infection, or irritants. While acute inflammation is an essential part of the healing process, chronic inflammation can lead to tissue damage and contribute to chronic diseases.

By reducing the production of inflammation-promoting molecules (like prostaglandins and leukotrienes) and balancing the immune response, quercetin may contribute to overall health and well-being. However, it’s important to note that its anti-inflammatory effects can vary based on factors such as dosage, absorption, and individual health conditions.

Immune System Support

Quercetin’s effects on the immune system are multifaceted and involve interactions with various immune cells and signaling pathways. While the exact mechanisms are complex and not fully explained, there are certain findings.

It is known that quercetin encourages the immune system to work effectively by activating immune cells that combat threats. Quercetin’s ability to regulate the release of signaling molecules called cytokines helps keep the immune response under control, preventing it from becoming overly aggressive. It also inhibits the release of histamine, which is associated with allergic reactions. Its antioxidant properties protect immune cells from harm, supporting their proper function. By enhancing protective barriers in tissues like the gut and respiratory tract, quercetin shields against unwanted invaders. Overall, this remarkable compound helps the immune system stay in harmony, preventing unnecessary inflammation or overactivity while maintaining its defense against potential harm.

Cardiovascular Health

The potential effects of quercetin on cardiovascular health are reflected in the reduction of cholesterol levels and blood pressure. Its antioxidant effect is associated with the protection of blood vessels against oxidative stress and reducing the risk of atherosclerosis. It can reduce the level of LDL cholesterol (the so-called bad cholesterol), which leads to plaque formation in the arteries (the leading cause of atherosclerosis). By maintaining proper circulation, it may reduce the risk of hypertension and thereby preserve the health of the cardiovascular system.

Blood Sugar Regulator

Quercetin’s potential benefits for blood sugar regulation lie in improving insulin sensitivity and secretion and influencing glucose metabolism. Through its antioxidant and anti-inflammatory properties, quercetin might enhance the body’s response to insulin, helping cells effectively use glucose for energy. By reducing the production of glucose in the liver, it may contribute to maintaining balanced blood sugar levels. These combined effects suggest that quercetin could be a valuable component in blood sugar control. This is crucial for preventing insulin resistance and lowering the risk of type 2 diabetes.

Cognitive Performances

Neuroinflammation is the leading cause of brain damage and the development of various brain diseases such as Alzheimer’s, Parkinson’s disease, and stroke. Studies on animals have shown the effect of quercetin on maintaining the health of neurons. By reducing neuroinflammation, quercetin plays a significant role in protecting the brain and preserving its function. Other than that, its influence on neurotransmitter activity and neural pathways suggests its potential to positively impact memory, learning, and overall cognitive performance. 

Allergy Relief

Mast cells, which store histamine, play a crucial role in the immune response to allergens. By stabilizing mast cell membranes, quercetin inhibits the release of histamine. As a result, this mitigation of the histamine reaction leads to a reduction in allergy symptoms such as sneezing, runny nose, itching, and swelling.

Anti-Infection Capabilities

Several studies highlight the antiviral and antimicrobial properties of quercetin. Due to its ability to inhibit the initial phases of viral infection and reduce inflammation, it can be useful as an adjunct to the regulation of these infections. There are other studies that confirm its effectiveness in certain bacterial infections.

Dosage, Precautions and Risks

When thinking about quercetin usage, it’s essential to consider dosage, precautions, and potential risks. While quercetin is generally considered safe, taking quercetin supplements in high doses may lead to gastrointestinal discomfort and headaches. Supplement dosages typically range from 500-1000 mg per day, divided into morning and evening doses.

Persons who are pregnant, breastfeeding, or have kidney diseases should consult their physician before using quercetin supplements. Other than that, quercetin may interact with certain medications, particularly blood thinners, antibiotics, or medications that affect liver enzymes. Although quercetin is generally safe, it’s important to approach its supplementation with caution, especially if combined with other supplements or medications.

The Bottom Line 

Although in vitro and animal studies have shown the remarkable benefits of quercetin, we need more research on humans. While we await promising scientific evidence on the benefits of quercetin, we cannot remain indifferent to its amazing properties.

FAQ

Is it safe to take quercetin daily?

It is safe to take quercetin every day in the recommended doses (500-1000 mg per day). After three months of use, you should take a break.

Is CoQ10 the same as quercetin?

Coenzyme Q10 (CoQ10) and quercetin are not the same. They are two different compounds with distinct roles and properties. Coenzyme Q10 is a naturally occurring antioxidant that plays a crucial role in the production of energy within cells and supports various cellular functions. It’s commonly taken as a dietary supplement to potentially improve heart health, increase energy production, and reduce fatigue.

On the other hand, quercetin is a flavonoid, a type of plant pigment found in various fruits, vegetables, and plants. It is known for its antioxidant and anti-inflammatory properties, and it’s often associated with benefits such as immune support, heart health, and allergy relief.

While both Coenzyme Q10 and quercetin offer potential health benefits, they have different mechanisms of action and applications.

Does quercetin increase testosterone?

There is some limited research suggesting that quercetin might have a potential impact on testosterone levels. However, the evidence is not conclusive, and more research is needed to fully understand its effects in this regard. Some studies have indicated that quercetin might influence testosterone levels by decreasing its renal excretion. Therefore, it’s theoretically possible that it could lead to a slight increase in testosterone levels. However, the actual magnitude of this effect and its consistency among humans are not well-established.

Who should not take quercetin?

1. Pregnant and breastfeeding women. There is not enough evidence on the safety of quercetin supplements for those conditions;
2. People with kidney disorders. Some studies have suggested that high doses of quercetin might be linked to kidney damage in certain cases;
3. People who are taking prescription medications such as blood pressure medications, antibiotics, and immunosuppressants.

When to take quercetin?

The best time to take quercetin is during meals, preferably at breakfast and dinner.

What is the best way to absorb quercetin?

Its absorption can be improved by various substances, including: 

• Healthy fats: Quercetin is a fat-soluble compound, so eating healthy fats can help its absorption. Take quercetin-rich foods or supplements with meals that include healthy fats such as olive oil, avocado, or nuts.
• Bromelain: Bromelain, an enzyme found in pineapple, has been shown to enhance the bioavailability of quercetin. Some quercetin supplements are formulated with bromelain, which may further enhance its absorption.
• Vitamin C: Vitamin C interacts with quercetin, forming a stable complex that can improve its absorption. Therefore, consuming quercetin supplements along with vitamin C may improve its bioavailability.

According to the definition, a free radical is any atom or molecule capable of independent existence that has a minimum of one unpaired electron in an atomic orbital. They can be positively charged, negatively charged, or neutral. Free radicals are unstable and extremely reactive, which means they act as oxidants or reductants. 

Wondering what effect free radicals have on the human body? While the simplest answer would be “harmful,” a more detailed explanation reveals the extent of their negative impact. Today, we are discovering what are free radicals, everything about oxidative stress, and the role of antioxidants in the whole story. Let’s start with the most vital information: 

What Are Free Radicals, and How Do They Damage the Body?

The extreme reactivity of free radicals causes cell damage. Whenever a free radical encounters another molecule and tries to find another electron to pair with its unpaired electron, damage occurs. Frequently, the free radical pulls an electron off an adjacent molecule, resulting in the transformed molecule becoming a free radical. That leads to a chemical chain reaction of free radical multiplication.

Once inside the cell, these molecules penetrate through all cell structures and attack cellular elements such as proteins, lipids, and DNA molecules. Long-term exposure to these cellular changes leads to many chronic diseases and conditions, as we will discuss later.

Types of Free Radicals

There are several types of free radicals, and they differ from each other based on the specific molecules involved. The most common types include:

• Hydroxyl radicals – Highly reactive and have a huge potential to damage cellular elements
• Superoxide radicals – Less reactive than hydroxyl radicals. They are formed as products of cellular respiration and metabolic processes
• Peroxyl radicals – Formed in reactions between oxygen and organic compounds and cause reactions that damage cell membranes
• Nitric oxide radicals – Nitric oxide is a signaling molecule in the body, but it can become a free radical in reaction with other molecules. It has a role in various physiological processes (it is responsible for proper blood flow function), but in excess, it becomes harmful
• Carbon-centered radicals – Very stable, persistent, and reactive molecules that are generated from environmental pollutants, toxins, or cellular processes involving organic molecules.

Oxidative Stress – Causes 

Oxidative stress represents an imbalance between the production and accumulation of free radicals in cells and tissues and the body’s ability to detoxify them. When the body is unable to defend itself, free radicals cause oxidative damage to cellular components, which further activates inflammation and leads to various diseases. 

In a healthy body, free radicals are produced as a byproduct of oxygen metabolism. However, various endogenous and exogenous factors also lead to free radical formation. Endogenous production of free radicals occurs due to the activation of immune cells, stress, different inflammations, aging, infections, and excessive exercise.

Exogenous causes include: 

• Radiation
• Tobacco smoke
• Alcohol
• Exposure to heavy metals
• Certain medicines
• Chemical solvents
• Certain procedures in food preparation (such as reusing oil in fryers)

Consequences of Oxidative Stress

All these factors can lead to oxidative damage in cells and tissues, the development of degenerative and chronic diseases, aging, and acute pathologies like trauma and stroke. The most famous diseases in which oxidative stress plays an important role are: 

• Metabolic syndrome – obesity, insulin resistance, dyslipidemia, impaired glucose tolerance
• Neurological diseases
• Infections and inflammations
• Diseases of the heart and blood vessels
• Kidney disease
• Diseases of the skin, eyes and joints
• Diabetes
• Cancer

Free Radicals and Aging

There are two theories about cellular aging: the mitochondrial theory and the free radical theory. According to the second one, the connection between free radicals and the aging process lies in the concept of oxidative stress. As we age, our bodies naturally accumulate those harmful molecules due to various factors such as metabolism, environmental exposures, and unhealthy habits. Free radicals interact with cellular components like DNA, proteins, and lipids, causing oxidative stress. This damage gradually impairs cellular function and contributes to the aging process. To counteract this, our bodies use antioxidants, substances that neutralize free radicals. However, an imbalance between free radicals and antioxidants, which occurs with aging, can lead to increased oxidative stress and accelerate aging. 

How to Reduce Oxidative Stress: The Role of Antioxidants  

The modern way of life, linked to an unhealthful diet, insufficient physical activity, and exposure to chemicals from diverse sources, including pesticides, heavy metals, food additives, and environmental pollution, has the potential to influence the occurrence of oxidative stress. This is where antioxidants come in to help us.

As we mentioned earlier, antioxidants are substances that directly counteract the harmful effects of free radicals. But how do antioxidants neutralize them at the molecular level? The answer is simple: Antioxidants mitigate the reactivity of free radicals by donating some of their own electrons. This is how they prevent the creation of radical chain reactions before other molecules become damaged.

The human body naturally produces some antioxidants, such as coenzyme Q10, melatonin, bilirubin, glutathione, and alpha lipoic acid. However, the necessary antioxidants can be obtained from various nutritional sources. In the following lines, we will reveal the types of antioxidants and antioxidant-rich foods.

Compounds With Antioxidant Properties

According to their chemical structures, there are many different types of antioxidants. They could be classified into seven main types:

1. Vitamins (vitamins A, C, and E)
2. Minerals (such as copper, zinc and selenium)
3. Polyphenols (essential compounds that cannot be synthesized in the human body)
4. Hormones (melatonin)
5. Carotenoids
6. Phenolic acids (compounds like chlorogenic acid, ellagitannins, gallic acid, and salicylic acid)
7. Other compounds (such as bilirubin – a breakdown product of hemoglobin, and capsaicin – spicy component of chili peppers)

Foods That Are High in Antioxidants

Among the most important antioxidants that our body does not produce are vitamins C, E, and A (synthesized from beta-carotene). They must be taken through a healthy diet or supplementation.

Let’s take a closer look at some delicious sources of antioxidants:

• Blueberries are packed with anthocyanins, a type of flavonoid, which gives them their vibrant color
• Apples are rich in quercetin, vitamin C, and flavonoid compounds
• Spinach is rich in vitamins A and C, as well as various phytochemicals like lutein and zeaxanthin
• Kale is a cruciferous vegetable containing compounds like glucosinolates and flavonoids
• Strawberries are a good source of vitamin C and anthocyanins, both of which have antioxidant properties
• Pecans contain various antioxidants, including vitamin E and polyphenols
• Artichokes contain compounds like quercetin, rutin, and other polyphenols
• Red beans are rich in anthocyanins and other flavonoids
• Raspberries are abundant in vitamin C, quercetin, and ellagic acid
• Walnuts contain a variety of antioxidants, including vitamin E, melatonin, and polyphenols
• Oranges are high in vitamin C, a powerful water-soluble vitamin
• Broccoli contains sulforaphane, a potent antioxidant and anti-inflammatory compound
• Tomatoes are rich in lycopene, a carotenoid with strong antioxidant properties
• Carrots are loaded with beta-carotene, a precursor to vitamin A that is well-known as a vision health keeper.

Antioxidant Supplements

During the 1990s, antioxidant supplements gained popularity for their potential to counteract oxidative stress and boost overall health. Among the most popular antioxidants are vitamins C and E, known for their ability to neutralize harmful effects and contribute to cellular protection.

Another prominent category includes polyphenol supplements derived from sources like berries, nuts, and grapes. Polyphenols show potent antioxidant properties, helping to mitigate cellular damage and inflammation. Polyphenol supplements have become popular due to the difficulty of getting enough polyphenols from food.

By adopting healthy eating patterns, engaging in regular physical activity, and avoiding destructive habits, we can maintain good health and pave the way to longevity. Through these changes, we are not only strengthening our bodies against oxidative stress but also enhancing our wellbeing and quality of life.

 

Frequently Asked Questions

 

What kills free radicals?

Antioxidants are molecules that neutralize free radicals by donating electrons to them, thus stabilizing them and preventing them from causing cellular damage. They essentially “kill” free radicals by breaking the chain reaction of oxidative stress. Our body produces some antioxidants, and they can also be obtained from various dietary sources, such as fruits, vegetables, nuts, and supplements. Consuming a diet rich in antioxidants is an effective way to counteract the harmful effects of free radicals.

 

Does vitamin C fight free radicals?

Yes, vitamin C is a powerful antioxidant that fights free radicals in the body. Except for neutralizing them, it also regenerates other antioxidants, like vitamin E. Consuming foods rich in vitamin C, such as citrus fruits, strawberries, and broccoli, can help reduce the harmful effects of free radicals and maintain cellular health.

 

What is the strongest antioxidant?

Astaxanthin is considered the strongest antioxidant. It belongs to the carotenoid group of compounds found in certain types of algae and seafood, such as salmon and krill. It deserves its title of strongest due to its potential to neutralize multiple types of free radicals.

 

Does coffee fight free radicals?

Coffee contains various compounds, including polyphenols, caffeine, and chlorogenic acid, that contribute to the reduction of oxidative stress in the body. Certain studies suggest that the consumption of coffee is associated with a lower risk of some chronic diseases, such as type 2 diabetes and neurodegenerative disorders like Parkinson’s and Alzheimer’s disease. These health benefits are often attributed, at least in part, to the antioxidant properties of coffee’s ingredients.

However, it’s important to note that the overall impact of coffee on health can vary depending on factors like genetics, the amount and type of coffee consumed, and the additives used. Coffee can be a good source of antioxidants when consumed in moderation as part of a healthy diet, but excessive consumption or adding a lot of sugar can negate those benefits.

Are you curious about longevity and related concepts about human lifespan? Wouldn’t you like to know more about factors that impact human longevity? Welcome to the exciting journey into the realm of longevity! 

Our goal is not only to inform but also to empower you. Armed with knowledge, we can make the right decisions that positively affect our well-being and pave the way for a future of lasting health and happiness.

To make things clear at the very beginning, let’s start from understanding longevity definition:

Longevity Definition

What does longevity mean? In simple terms, we could define it as the long length of an individual’s lifespan. However, as we will analyze later, it goes far beyond that basic longevity definition. Human longevity is a holistic approach that encompasses physical, mental, emotional, and social well-being, promoting a harmonious balance between the various aspects of our existence.

Between Myth and Art

Throughout history, the pursuit of longevity has been a central focus of human endeavors. From ancient civilizations seeking the secrets of longevity in elixirs of immortality to modern scientific breakthroughs, the quest to unravel the mysteries of a long life has been relentless.

There are many myths and stories on this topic. Themes of long life and eternal youth have occupied many artists and created some of the most beautiful pieces of art of all time. From ancient cave drawings and sculptures to timeless literary works and masterful paintings, these artistic masterpieces serve as testaments to the timelessness of the aim for longevity, beauty, and vitality.

What Does Science Say?

There are many interwoven factors that impact the lifespan of human beings. However, we could classify them into three major groups:

1. Genetic inheritance
2. Lifestyle
3. Environmental influence

Let’s dive deeper into every one of them.

Genetic Inheritance

Our genetic inheritance plays a vital role in determining the length and quality of our lives. It’s like a blueprint that carries information influencing various aspects of our health and aging. It is impossible to change our genes, but understanding their impact empowers us to make informed choices to manage potential risks and leverage strengths.

Scientists have found that certain genetic variations can affect our susceptibility to diseases, our metabolism, and cellular repair processes. Those three actors play a vital role in the aging process. It’s important to remember that genetics is only one part of the equation; lifestyle and environmental factors also play significant roles in shaping our overall longevity.

Lifestyle

The way we live day to day has a significant impact on our longevity. Healthy lifestyle habits can reduce the risk of chronic diseases and increase our chances of living longer. Physical activity and healthy eating habits are the most important lifestyle factors that impact our health. Regular physical activity is associated with better cardiovascular health, stronger bones, and a lower risk of common age-related conditions. Healthy food provides essential nutrients that support various bodily functions and help maintain optimal health. It is also important to maintain your ideal weight throughout life. Minor deviations in certain circumstances and periods of life are completely normal. Despite those exceptions, we should maintain our body weight in the optimal range.

Don’t forget about lifestyle choices. Smoking, for instance, damages almost every body organ and carries a high risk of heart diseases, diabetes, inflammation, lung diseases, and premature aging. Choosing not to consume alcohol and cigarettes may be your best health choice.

Environmental Influence

The environment we live in impacts our longevity in various ways. The quality of water, air, and food is of inestimable value for human health. Exposure to environmental pollutants and toxins can have adverse effects on health, potentially leading to the development of various diseases. Additionally, the availability and quality of healthcare services significantly impact our ability to manage and treat different health conditions, ultimately influencing life expectancy.

Determining Longevity: Other (Not-So-Negligible) Factors

Beyond genetic inheritance, lifestyle choices, and environmental influences, several other factors exert their influence on longevity. These elements, often not as easily quantifiable as traditional medical indicators, play integral roles in shaping the length and quality of our lives.

Let’s delve into these factors:

Having a Life Purpose

Discovering your life purpose can have a profound impact on your overall health and well-being. Research has shown that individuals with a strong sense of purpose tend to live longer and experience better overall health. By having a clear life purpose, you gain a sense of direction and motivation, which leads to healthier behaviors and reduced stress. Whether it’s through meaningful work, caregiving, or hobbies, having a purpose can imbue life with a deep sense of fulfillment and contentment.

Attitude Towards Life

Embracing an optimistic outlook can have a profound effect on how long we live. Research has shown that having a positive attitude towards life can help us better navigate tough times, decrease our chances of experiencing depression, and improve our overall mental well-being. Approaching challenges with resilience and maintaining a hopeful perspective may contribute to a longer and more vibrant life.

The way Japanese people eat, which includes a lot of fresh food, fish, algae, and plant food, as well as consuming small meals, contributes to their longer lifespan.

Have you ever wondered why you naturally feel more awake during the day and sleepier at night? This is all thanks to your body’s internal clock, known as the circadian rhythm. Circadian rhythm is a biological system that regulates various mental, physical, and behavioral functions over a 24-hour period. It influences when you feel alert and when you feel sleepy, as well as essential physiological processes like hormone release, body temperature, and metabolism. If you’re looking to learn how to fix circadian rhythm, first you should discover what it is and then look for strategies that work.

What Is a Circadian Rhythm, and How Does It Work? 

The human body is a unit controlled by the circadian clock in the brain. Among the many processes it affects, this “controller” also regulates the circadian rhythm. 

There is a small part of the brain called the suprachiasmatic nucleus (SCN). This area is found in the hypothalamus. It receives signals about sleepiness, alertness, and other bodily needs depending on the time of day. Through hormones, the circadian rhythm controls all organ systems. This is how we know when we are hungry or sleepy. Light is the most important indicator that affects the SCN, and it is the reason why we feel sleepy at night and awake during the day. Circadian rhythm is not exclusive to the human species. All kinds of organisms, including plants, have this rhythm.

However, every stage of life has its own way of regulating this rhythm. Thus, babies sleep for longer periods of time and more frequently throughout the day, while the need for sleep decreases with aging. 

What Affects Circadian Rhythm?

A variety of factors and their interaction influence the circadian rhythm:

Hormones

Hormones like cortisol and melatonin, coupled with metabolic processes, regulate periods of alertness and restfulness. Cortisol (the stress hormone) peaks in the morning, promoting wakefulness, while melatonin (the sleep hormone) increases in the evening, preparing the body for rest.

Body Temperature

Fluctuations in body temperature also affect this rhythm. Before sleep, the body’s temperature drops slightly.

External Factors

External elements like overnight work shifts or stress can disrupt this rhythm, causing misalignment between your internal clock and the external environment. Heightened stress levels can lead to an increase in cortisol production and hamper sleep onset and duration.

Jet Lag

Jet lag is another potent influencer. Frequent travel across different time zones confuses the body’s internal clock and leads to a misalignment between the local day-night cycle and your circadian rhythm. This mismatch results in fatigue, sleep issues, and difficulties adjusting to the new time zone.

Medications and Mental Condition

Medications, too, play a big role. Certain drugs, especially those affecting the nervous system or having drowsiness as a side effect, can interfere with the circadian rhythm and disrupt sleep patterns. Circadian rhythm disorders can also be triggered by mental health problems such as depression and anxiety.

Electronic Device Screens

At the very end of this list, let’s not forget an important factor we are all exposed to – electronic devices. Excessive exposure to natural light or the use of electronic devices before sleep can also disrupt this rhythm, further affecting sensitivity to both internal and external factors.

How to Fix Circadian Rhythm: Advice for Realigning Your Internal Clock

Restoring a healthy circadian rhythm involves a combination of calming practices:

1. Keep a consistent schedule: Establishing the same sleep and wake times helps regulate your body’s internal clock, leading to better sleep quality and overall well-being.
2. Limit alcohol and caffeine: Avoiding these substances close to bedtime minimizes their sleep-disruptive effects and assists in harmonizing your sleep-wake cycle.
3. Reduce the usage of electronic devices: Refrain from looking at screens before sleeping. The blue light can interfere with melatonin production, which is essential for quality sleep.
4. Opt for early dinners: Avoiding eating close to bedtime allows your body to digest food better and decreases the chances of sleep disruptions. Choose nourishing and light meals based on proteins and healthy fats.
5. Enjoy natural light: Expose your body to sunlight during the day (whenever possible), as it signals your body wakefulness. It will also help you meet your daily needs for vitamin D.
6. Manage stress and engage in physical activity: Incorporating stress-reduction techniques and regular physical activity into your routine is essential for maintaining a balanced circadian rhythm. Managing stress can reduce the risk of sleep disturbances and improve sleep quality. Besides, engaging in regular physical activity always leads to better sleep patterns. 
7. Pay attention to hydration: Maintaining proper hydration is often overlooked, but it can influence your circadian rhythm. During the day, drink water regularly, but consider reducing fluid intake before bedtime to prevent disruptive nighttime awakenings. 
8. Set up an optimal sleep environment: Before going to bed, ensure your sleep space is dark, quiet, and comfortable. Block out sources of external light, consider blackout curtains, and minimize noise disruptions. A comfortable mattress and pillows are essential for restful sleep. 

By incorporating these practices into your everyday routine, you can reset your circadian rhythm, improve your sleep patterns, and overall well-being.

When Is the Time to Reset Circadian Rhythm?

The signs of a disrupted circadian rhythm can manifest in various ways and impact both your physical and mental conditions. Symptoms such as constant low energy levels can leave you feeling lethargic and drained, while mood changes may contribute to emotional instability. Unexplained food cravings and challenges with weight management can stem from an imbalance in your internal clock. Other than that, increased nervousness and difficulties with focus and concentration can be indicative of circadian rhythm misalignment. Other symptoms may include weakened immunity, irregular sleep patterns, and a constant sense of fatigue.

If you find it challenging to fall asleep at night or struggle to wake up in the morning, even with consistent effort, it’s time to consider resetting your circadian rhythm. By prioritizing healthy sleep habits, regulating your exposure to light, and incorporating relaxation techniques, you can realign your rhythm and restore balance to your body.

Types of Circadian Rhythm Disorders

Types of circadian rhythm disorders encompass different sleep and wake patterns. Let’s take a closer look at each:

• Delayed sleep phase disorder involves a tendency to fall asleep and wake up later than desired, often causing difficulties adhering to regular schedules. 
• Advanced sleep phase disorder leads to an earlier sleep onset and wake time, sometimes causing early evening sleepiness.
• Irregular sleep-wake disorder results in fragmented sleep throughout the day and night, with no distinct nighttime sleep. 
• Shift work disorder results from irregular working hours, causing sleep difficulties and insufficient wakefulness during shifts. 
• Non-24-hour sleep-wake disorder is characterized by an irregular sleep-wake cycle caused by a lack of light cues.

Possible Consequences of Circadian Rhythm Disorder  

These kinds of disorders can lead to a cascade of consequences that affect physical, mental, and emotional health. Constant sleep deprivation weakens the immune system, which renders the body more susceptible to infections and illnesses. The interaction between circadian rhythm and hormone regulation can disturb metabolic processes and contribute to weight gain, diabetes, and cardiovascular issues. These disorders can sometimes lead to mental health problems like depression and anxiety. Cognitive functions such as memory, attention, and problem-solving abilities may also be compromised due to inadequate sleep alignment.

Circadian rhythm disorders impact daily functioning and performance. Individuals with these problems experience challenges maintaining a regular routine, leading to difficulties in professional life, education, and social interactions. Relationships can suffer due to mood changes, irritability, and daytime sleepiness, leading to an overall diminished quality of life.

In essence, the consequences of these disorders extend far beyond sleep. Addressing these disorders through lifestyle adjustments, therapeutic interventions, and appropriate medical guidance is crucial not only for restoring healthy sleep patterns but also for maintaining overall physical and mental health.

Key Considerations

Now that we know how many complex functions in the body are controlled by the circadian rhythm, we can draw a conclusion. Getting your circadian rhythm back on track isn’t a science, but it requires discipline and patience. Maintaining proper eating and exercise habits while reducing the harmful impact of sleep-disrupting factors collectively form a solid foundation for positive changes. At the very end, remember one important fact: once you adopt healthy habits, try to keep them permanently. That is the only way to maintain good health.

 

Frequently Asked Questions

 

What happens when your circadian rhythm is off?

When your circadian rhythm is off, a range of problems can occur across various aspects of your physical, mental, and emotional health. Your sleep patterns may become irregular, making it difficult to fall asleep, stay asleep, or wake up at the desired times. This leads to persistent fatigue, reduced alertness, and impaired cognitive functions, which affect your daily performance and productivity. A disturbed rhythm can also affect your metabolism and lead to obesity. Over time, the immune system weakens, which makes you more susceptible to infections and illnesses. 

 

Is it healthy to wake up at 4 a.m.?

It is good for your body if waking up at 4 a.m. corresponds to your natural rhythm and allows you to get enough sleep (7-9 hours). However, if waking up this early disturbs your sleep, it will cause negative effects such as fatigue, impaired cognitive functions, and mood disorders.

 

What hormone regulates circadian rhythms?

The hormone that primarily regulates circadian rhythms is melatonin. Melatonin is produced by the pineal gland in response to darkness. It plays a crucial role in signaling the body that it’s time to sleep. Melatonin levels typically rise in the evening as light levels fall, increasing drowsiness and preparing the body for sleep, and then fall in the morning as light levels rise, signaling wakefulness. Other hormones, such as cortisol, also contribute by regulating alertness and energy levels throughout the day.

 

Can you use melatonin to reset circadian rhythm?

Yes, melatonin supplements can be used to help reset the circadian rhythm, especially in cases of disorders such as jet lag or night shift work. Melatonin supplements are commonly used as a short-term aid to change sleeping and waking patterns. Taking melatonin supplements a few hours before the desired bedtime induces sleepiness and facilitates the transition to a new sleep schedule. While melatonin supplements can be effective as a short-term solution, they are not suitable for long-term use or for insomnia treatment.
