Vitamin E is found Poweeful the body in eight different forms, Powerful antioxidant supplements the form antioxirant our bodies primarily use Sports nutrition for triathletes called alpha-tocopherol.
Vitamin E has potent antloxidant properties, especially in antioxidanh cardiovascular and immune systems. Atioxidant the Powfrful system, the antioxidant properties of Vitamin E prevent Powerful antioxidant supplements oxidation of cholesterol.
When cholesterol becomes supplementw, it is more likely Powerfu form a clot and thus cause heart attacks and strokes. Vitamin E also causes the Powergul vessels to widen, supplemente dilation, making it harder for clots to Powerful antioxidant supplements to the blood vessel wall.
Because of these immune system actions, vitamin E may lower the risk of the development of respiratory and allergic diseases like asthma.
Vitamin E is found in many foods, including wheat germ, sunflower seeds, almonds, hazelnuts, and peanuts. Often called ascorbic acid, vitamin C is a vitamin humans cannot make and must obtain through their diet. Because vitamin C is water soluble, its antioxidant effects can occur both inside and outside cells.
While vitamin C is an incredibly effective antioxidant on its own, it has shown to be even more effective when teamed up with other antioxidants.
Vitamin C and glutathione are a powerful match for hydrogen peroxide, a strong free radical. Vitamin C can also facilitate the regeneration of vitamin E, which, as discussed above, is yet another antioxidant.
Vitamin C can be found in fresh foods, including red peppers, oranges, kiwi, green peppers, and broccoli. Selenium is a nutrient required for human health. Important for reproductive, immune, and endocrine functions, this antioxidant has a wide variety of effects.
Selenium is required for a group of enzymes called selenoproteins to function correctly. There are more than 24 different types of selenoproteins. However, there is one type that is most pertinent to this article: glutathione peroxidases. Glutathione peroxidases are a type of selenoprotein that is also dependent upon the above-discussed antioxidant, glutathione.
They have many antioxidant actions in the body but have a significant effect on the production and function of sperm, making their functionality especially important for male fertility. Selenium can be found in high amounts in Brazil nuts, tuna, halibut, sardines, and ham.
Antioxidants can be measured in units of millimoles Trolox equivalents mmol TE. Scientists have gathered data to determine the ideal amount of antioxidant intake per day.
For those consuming 2, calories daily, the antioxidant intake needs are estimated to be Thankfully for us, many wonderful foods are packed with high amounts of antioxidants.
Researchers have various ways of assessing antioxidant levels in foods. One of the best ways to determine antioxidants in foods is the ferric-reducing ability of plasma FRAP test. This test measures foods against specific free radicals and analyzes how they neutralize them.
Dark chocolate is a favorite and a dessert choice for many people; luckily for them, it also comes with health benefits. Dark chocolate contains a type of antioxidant called flavanols, which may help with blood pressure and vision and may also reduce the risk of cardiovascular disease and diabetes.
Dark chocolate contains 15 mmol of antioxidants per 3. Pecans are a type of nut with many vitamins and minerals. Pecans contain magnesium, potassium, and calcium. They contain protein, carbohydrates, and fats, unsaturated fats, to be specific, which can aid in healthy cholesterol levels.
The FRAP score for pecans was up to of pecans. Blueberries are a popular fruit that have been enjoyed for centuries. Because of their antioxidant, vitamin, and mineral levels, blueberries may be beneficial for high cholesterol, high blood pressureand diabetes. The FRAP score for blueberries was up to 9.
Strawberries are a delicious red fruit with chock-full of fiber, vitamins, minerals, and other antioxidants. Research suggests strawberries may be beneficial for those with insulin sensitivity and osteoarthritis and may also help protect skin from sun damage.
Wild strawberries had a FRAP score of up to 5. If not harvested, what we call an artichoke would bloom into a beautiful purple flower. Some research suggests artichokes may be beneficial for blood pressure, cholesterol, and liver health due to their antioxidant content.
Artichokes FRAP score was up to 4. Cooking does affect antioxidant levels; however, how it affects them varies by cooking preparation. A study was done in the journal Antioxidants assessing three different cooking methods, frying, boiling, and steaming, on six different edible leaves that contained various antioxidants, including polyphenols and carotenoids.
Results showed that frying reduced the number of antioxidants while boiling and steaming actually increased antioxidant levels in some of the leaves! Antioxidants, as discussed above, can confer many health benefits by fighting free radicals.
However, like many things in life, even too much of a good thing can turn bad. Elevated levels of certain antioxidants may not only not have benefits but may even negatively impact health.
For example, in smokers, high levels of beta-carotene may increase the risk of lung cancer. High doses of vitamin E may raise the risk of prostate cancer and strokes. This is why it's crucial to work with a practitioner before starting any new supplement regime. It also highlights the importance of testing.
Testing levels can take the guessing out of deciding which supplement is right or appropriate for you. The urinary marker 8-hydroxy-2'-Deoxyguanosine 8-OHdG is an indicator of the current level of oxidative stress in the body.
Research supports the use of 8-OHdG to evaluate the risk of degenerative diseases and cancers as it is a popular form of free radical oxidation and can give insight into DNA damage. The research done has primarily measured 8-OHdG after exposure to oxidants, including tobacco smoke, heavy metals, polycyclic aromatic hydrocarbons, and asbestos fibers.
Doctors Data offers a single-marker 8-OHdG testand this marker is also found on the Precision Analytical DUTCH Complete hormone test.
A micronutrient test checks levels of various vitamins, minerals, fatty acids, and more, giving their specific levels. Many micronutrients are antioxidantsincluding vitamin E, vitamin Cselenium, and zinc. Many micronutrient tests also check levels of glutathione, the powerhouse antioxidant.
Antioxidants are powerful molecules that can significantly alter our health. Antioxidants can be obtained through our diet, including glutathione from spinach, CoQ10 through meat, vitamin E through wheat germ, vitamin C through red peppers, and selenium through Brazil nuts.
Additionally, foods with high amounts of numerous antioxidants include dark chocolate, pecans, blueberries, strawberries, and artichokes.

Some substances that act as antioxidants in one situation may be pro-oxidants—electron grabbers—in a different situation. Another big misconception is that antioxidants are interchangeable. Each one has unique chemical behaviors and biological properties. They almost certainly evolved as parts of elaborate networks, with each different substance or family of substances playing slightly different roles. This means that no single substance can do the work of the whole crowd. Antioxidants came to public attention in the s, when scientists began to understand that free radical damage was involved in the early stages of artery-clogging atherosclerosis. It was also linked to cancer , vision loss, and a host of other chronic conditions. Some studies showed that people with low intakes of antioxidant-rich fruits and vegetables were at greater risk for developing these chronic conditions than were people who ate plenty of those foods. Clinical trials began testing the impact of single substances in supplement form, especially beta-carotene and vitamin E, as weapons against chronic diseases. Supplement makers touted the disease-fighting properties of all sorts of antioxidants. The research results were mixed, but most did not find the hoped-for benefits. Antioxidants are still added to breakfast cereals, sports bars, energy drinks, and other processed foods , and they are promoted as additives that can prevent heart disease, cancer, cataracts, memory loss, and other conditions. Randomized placebo-controlled trials, which can provide the strongest evidence, offer little support that taking vitamin C, vitamin E, beta-carotene, or other single antioxidants provides substantial protection against heart disease, cancer, or other chronic conditions. The results of the largest trials have been mostly negative. A modest effect of vitamin E has been found in some studies but more research is needed. A study from the Journal of Respiratory Research found that different isoforms of vitamin E called tocopherols had opposing effects on lung function. Lung function was tested using spirometric parameters: higher parameters are indicative of increased lung function, while lower parameters are indicative of decreased lung function. The study found that higher serum levels of alpha-tocopherol were associated with higher spirometric parameters and that high serum levels of gamma-tocopherol were associated with lower spirometric parameters. Though the study was observational in nature, it confirmed the mechanistic pathway of alpha- and gamma-tocopherol in mice studies. When it comes to cancer prevention, the picture remains inconclusive for antioxidant supplements. Few trials have gone on long enough to provide an adequate test for cancer. High-dose antioxidant supplements can also interfere with medicines. Vitamin E supplements can have a blood-thinning effect and increase the risk of bleeding in people who are already taking blood-thinning medicines. Some studies have suggested that taking antioxidant supplements during cancer treatment might interfere with the effectiveness of the treatment. Inform your doctor if starting supplements of any kind. One possible reason why many studies on antioxidant supplements do not show a health benefit is because antioxidants tend to work best in combination with other nutrients, plant chemicals, and even other antioxidants. For example, a cup of fresh strawberries contains about 80 mg of vitamin C, a nutrient classified as having high antioxidant activity. Polyphenols also have many other chemical properties besides their ability to serve as antioxidants. There is a question if a nutrient with antioxidant activity can cause the opposite effect with pro-oxidant activity if too much is taken. This is why using an antioxidant supplement with a single isolated substance may not be an effective strategy for everyone. Differences in the amount and type of antioxidants in foods versus those in supplements might also influence their effects. For example, there are eight chemical forms of vitamin E present in foods. However, vitamin E supplements typically only include one form, alpha-tocopherol. Epidemiological prospective studies show that higher intakes of antioxidant-rich fruits, vegetables, and legumes are associated with a lower risk of chronic oxidative stress-related diseases like cardiovascular diseases , cancer, and deaths from all causes. The following are nutrients with antioxidant activity and the foods in which they are found:. Excessive free radicals contribute to chronic diseases including cancer, heart disease, cognitive decline, and vision loss. Keep in mind that most of the trials conducted have had fundamental limitations due to their relatively short duration and inclusion of people with existing disease. At the same time, abundant evidence suggests that eating whole in fruits , vegetables , and whole grains —all rich in networks of naturally occurring antioxidants and their helper molecules—provides protection against many scourges of aging.

In , a rating tool called the Oxygen Radical Absorbance Capacity ORAC was created by scientists from the National Institute on Aging and the United States Department of Agriculture USDA. It was used to measure the antioxidant capacity of foods. The USDA provided an ORAC database on its website highlighting foods with high ORAC scores, including cocoa, berries, spices, and legumes. Blueberries and other foods topping the list were heavily promoted in the popular press as disease-fighters even if the science was weak, from cancer to brain health to heart disease. However, 20 years later the USDA retracted the information and removed the database after determining that antioxidants have many functions, not all of which are related to free radical activity. Although this was not a primary endpoint for the trial, it nevertheless represents an important outcome. In the Heart Outcomes Prevention Evaluation HOPE trial, the rates of major cardiovascular events were essentially the same in the vitamin E A recent trial of vitamin E in Israel, for example, showed a marked reduction in coronary heart disease among people with type 2 diabetes who have a common genetic predisposition for greater oxidative stress. In the Supplementation en Vitamines et Mineraux Antioxydants SU. MAX study, 13, French men and women took a single daily capsule that contained mg vitamin C, 30 mg vitamin E, 6 mg beta-carotene, mcg selenium, and 20 mg zinc, or a placebo, for seven and a half years. The vitamins had no effect on overall rates of cardiovascular disease.

Lab Tests in This Article DUTCH Complete Dried Urine. The cis-configuration has much better bioavailability. Carotenoids are fat-soluble compounds; in the human body, they are found in fatty tissue and transported by lipoproteins. They act as dietary precursors to vitamin A and aid the immune system.
Lycopene is also highly lipophilic and is commonly found within cellular membranes. It is a powerful antioxidant that can quench singlet-oxygen free radicals twice as efficiently as beta-carotene.
Singlet oxygen is not a stable molecule but an unstable energy-rich form that is an aggressive radical. Coenzyme Q 10 Coenzyme Q 10 CoQ10 , or ubiquinone, is essentially a vitamin or vitamin-like substance. The biosynthesis of CoQ10 from the amino acid tyrosine is a multistage process requiring at least eight vitamins and several trace elements.
CoQ10 is the coenzyme for at least three mitochondrial enzymes as well as enzymes in other parts of the cell.
Mitochondrial enzymes of the oxidative phosphorylation pathway are essential for the production of the high-energy phosphate or adenosine triphosphate upon which all cellular functions depend. The electron and proton transfer functions of the quinone ring are of fundamental importance to all life forms.
CoQ10 has been the focus of scientific study for years and has become one of the most popular dietary supplements. It plays a crucial role in producing energy in cells.
It acts as a powerful antioxidant, meaning that it helps neutralize cell-damaging molecules or free radicals. Manufactured by all cells in the body, CoQ10 is also found in small amounts in foods, notably meat and fish.
CoQ10 declines in the body as people age or develop certain diseases such as some cardiac conditions, Parkinson's disease, and asthma. But that doesn't mean that lower levels of CoQ10 cause disease, or that supplemental CoQ10 will combat disease or reverse the effects of aging.
Some drugs, including certain cholesterol-lowering statins, beta-blockers, and antidepressants, can reduce CoQ10 levels in the body, but there has been no evidence that this causes any adverse effects. Researchers at the University of California, San Diego, found that very large doses of CoQ10 along with vitamin E appeared to slow the progression of Parkinson's disease.
It reduced the decline in neurologic function and improved daily life. Because the study was small, the researchers determined that larger trials were needed before they could recommend CoQ But the new study on Parkinson's disease tested , , and 1, mg, with the largest dose having the greatest effect.
Since CoQ10 is fat-soluble, it is probably best to take it with meals containing at least a little fat. It was discovered in and serves as a coenzyme in the Krebs cycle and in the production of cellular energy. In the late s, researchers realized that alpha-lipoic acid had been overlooked as a powerful antioxidant.
It neutralizes free radicals in both the fatty and watery regions of cells, in contrast to vitamin C which is water soluble and vitamin E which is fat soluble. It is also a highly effective therapeutic agent in a number of conditions in which oxidative damage has a major role.
Both forms of lipoic acid quench peroxynitrite radicals, an especially dangerous type consisting of both oxygen and nitrogen. Peroxynitrite radicals play a role in the development of atherosclerosis, lung disease, chronic inflammation, and neurological disorders.
It speeds the removal of glucose from the bloodstream, at least partly by enhancing insulin function, and it reduces insulin resistance. In the United States, it is sold as a dietary supplement, usually as mg tablets. The richest food source of alpha-lipoic acid is red meat. Ellagic Acid Ellagic acid is a plant-derived polyphenol and a superantioxidant that inhibits hydroxyl radicals.
It is mainly found in pomegranates. Pomegranates have been grown in Asia and the Middle East for millennia for spiritual as well as health reasons. Western medicine has only recently realized the importance of this superantioxidant, which is gaining popularity in the prevention and treatment of cancer and heart disease.
Aviram et al. showed that pomegranate juice contains the highest antioxidant capacity compared with other juices, red wine, green tea, tomatoes, vitamin E, and other sources of antioxidants. Their research indicated that pomegranate juice contains at least three major antioxidants, and the juice has three times the antioxidant power of red wine or green tea.
Instead, polymers of gallic acid and hexahydroxydiphenoyl HHDP are linked to glucose centers to form the class of compounds known as ellagitannins. When two gallic acid groups become linked side by side within a tannin molecule, an HHDP group is formed. Ellagic acid is the result when the HHDP group is cleaved from the tannin molecule and spontaneously rearranges.
It is the ellagitannins that are found in pomegranates. The juice has increased the prostate specific antigen doubling time in cancer patients with rising PSA after surgery or radiation. The research has found the positive effects of the juice on prostate cancer in in vitro cell proliferation and apoptosis as well as oxidative stress.
Green Tea Green tea has been consumed for centuries in India, China, Japan, and Iran, and in traditional Chinese and Indian medicine, it has been used as a stimulant for somnolence , diuretic to promote the excretion of urine , astringent to control bleeding and help heal wounds , and to improve heart health.
Other traditional uses of green tea include treating flatulence, regulating body temperature and blood glucose levels, promoting digestion, and improving mental processes.
There are three main varieties of tea--green, black, and oolong Camellia sinensis. Green and oolong teas are more commonly consumed in Asian countries, while black tea is most popular in the U.
The difference between the teas is in their processing. Green tea is prepared from unfermented leaves, oolong tea from partially fermented leaves, and black tea from fully fermented leaves. The more the leaves are fermented, the lower the polyphenol content and the higher the caffeine content. Polyphenols are chemicals that act as powerful antioxidants.
Compared with black tea, green tea has a higher polyphenol content; however, black tea has roughly two to three times the caffeine content of green tea. Green tea contains six primary catechin compounds: catechin, gallocatechin, epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate also known as EGCG.
EGCG is considered to be the most active component in green tea and is the best researched of all the green tea polyphenols. Green tea also contains alkaloids, including caffeine, theobromine, and theophylline. These alkaloids provide green tea's stimulant effects. Consistent tea consumption leads to a significant increase in the antioxidant capacity of the blood.
Beneficial effects of increased antioxidant capacity in the body may be the reduction of oxidative damage to important biomolecules. The scientific support is strongest for the protection of DNA from oxidative damage after black or green tea consumption.
In fact, this nu trient plays a major role in the manufacture and defense of our connective tissue, the elaborate matrix that holds the body together. It serves as a primary ingredient of collagen, a glue-like substance that binds cells together to form tissues.
Vitamin C helps some of our most important body systems. First and foremost, it helps the immune system to fight off foreign invaders and tumor cells. In addition, vitamin C supports the cardiovascular system by facilitating fat metabolism and protecting tissues from free radical damage. It also assists the nervous system by converting certain amino acids into neurotransmitters.
The skin, teeth, and bones also benefit from vitamin C's collagen-forming and invader-resisting properties; this vitamin contributes to the maintenance of healthy bones, the prevention of periodontal disease, and the healing of wounds.
It combats inflammation and pain by inhibiting the secretion of prostaglandins, which contribute to such symptoms. It works in collaboration with vitamin E, a fat-soluble antioxidant, and the enzyme glutathione peroxidase to stop free radical chain reactions.
Vitamin C is an excellent source of electrons; therefore, it can donate electrons to free radicals, such as hydroxyl and superoxide radicals, and quench their reactivity. Large concentrations of vitamin C can be found in fruits such as oranges, grapefruits, tangerines, lemons, and limes.
Vitamin C and bioflavonoids--the water-soluble substances that help to protect human capillaries--are found in the white linings of these and other plants. Many vegetables also contain vitamin C, including tomatoes, broccoli, green and red bell peppers, raw lettuce, and other leafy greens.
Studies suggest that vitamin C's antioxidant mechanisms may help to prevent cancer in several ways. For example, vitamin C combats the peroxidation of lipids, which has been linked to degeneration and aging. The recommended daily allowance of vitamin C is mg. Each form has its own biological activity, which is the measure of potency or functional use in the body.
Alpha-tocopherol is the most active form of vitamin E in humans. It is also a powerful biological antioxidant. Vitamin E supplements are usually sold as alpha-tocopheryl acetate, a form that protects its ability to function as an antioxidant.
The synthetic form is labeled "D, L" while the natural form is labeled "D. Studies are under way to determine whether vitamin E, through its ability to limit production of free radicals, might help prevent or delay the development of some chronic diseases such as cardiac diseases.
Vitamin E has also been shown to play a role in immune function, DNA repair, and other metabolic processes. Selenium is used by our bodies to produce glutathione peroxidase, a component of the body's natural antioxidant defense system that is manufactured in the liver.
It works with vitamin E to protect cell membranes from damage caused by harmful free radicals and helps to detoxify harmful compounds in the liver.
Additionally, some glutathione is released into the bloodstream, where it helps to maintain the integrity of red blood cells while protecting immune system white blood cells as part of the body's defense.
Eighteen patients received no supplementation, 14 patients received oral selenium, and 13 patients received oral beta-carotene for a period of one year.

It's difficult to determine Powerful antioxidant supplements suppplements antioxidants as antioxidnt types antioxiant antioxidants Powerful antioxidant supplements different roles and functions in the body. However, some of the most Powerful antioxidant supplements recognized potent antioxidants include vitamin C, vitamin E, beta-carotene, selenium, and glutathione. The richest sources of antioxidant foods include dark chocolate, blueberries, walnuts, goji berries, and coffee. Antioxidants are substances that protect cells from damage caused by free radicals. Free radicals are unstable molecules produced by the body as a result of normal metabolic processes, and can also come from external sources such as pollution, radiation, and cigarette smoke.
