Although antioxidant supplements aren't shown to be beneficial to health, they may be helpful if you have a deficiency. For example, if you are deficient in vitamin C, a vitamin C supplement may help normalize your vitamin C levels and prevent unwanted side effects of a deficiency.

According to the NIHthese could include delayed wound healing and gum inflammation. That's not to say that you'll reap added antioxidant benefits; you'll ensure your body has enough of the nutrient to meet its basic needs for optimal functioning. The Selenium and Vitamin E Cancer Prevention Trial SELECT was a large clinical trial conducted by the National Cancer Institute that concluded in Researchers determined this difference to be statistically significant and not just related to chance.

In the same study, participants taking selenium with or without vitamin E also had a higher incidence of prostate cancer; however, this difference was not statistically significant.

Beta carotene supplementation has been found to increase the risk of lung cancer in people who smoke. Before starting any supplement, it's best to talk with a health care provider to be sure it won't interact with any medications you're taking.

Here are some examples of how antioxidant supplements can potentially interact with medications:. To boost your antioxidant intake, we recommend leaning on food sources. The best sources of antioxidants are fruits and veggies, but dark chocolategreen tea and nuts are other good sources.

Here are some ideas to give your meals and snacks an antioxidant boost:. In general, antioxidant supplements are unnecessary for healthy people without a nutrient deficiency. They are not shown to have the same health benefits as consuming antioxidant-rich foods like fruits and vegetables.

So, it's best to focus on eating more plant foods rich in naturally occurring antioxidants. Since antioxidant supplements don't have the same research-backed benefits as antioxidant-rich foods, you probably don't need to take an antioxidant supplement at all, let alone every day.

That being said, if you are deficient in an antioxidant like vitamin C or E, daily supplementation is usually recommended to replenish your levels of the nutrient and reverse or prevent side effects from a deficiency. The most powerful antioxidant supplement is the one you are deficient in. If you don't have a deficiency in a specific antioxidant nutrient, then you probably won't benefit from taking a supplement.

And you'd be better off focusing on incorporating more antioxidant-rich foods in your diet. Antioxidant-rich foods, like fruits and veggies, are associated with loads of health benefits and no safety concerns, whereas supplements may lead to harm when overdone or taken with certain medications.

Antioxidant supplements are linked with health issues in certain populations. Since they contain highly concentrated doses of nutrients, they may increase the risk of toxicity.

They can also interact with medications, potentially decreasing the medication's effectiveness or exacerbating its effects. Antioxidant supplements are also expensive, so they can put an unnecessary dent in your wallet.

Despite how alluring antioxidant supplements may be, research shows that they don't really benefit health unless you're deficient in the given nutrient. That being said, adding more antioxidant-rich foods to your diet can benefit your health in numerous ways since antioxidant-rich foods are also rich in nutrients like fiber, which have a plethora of health benefits.

For instance, men who eat plenty of the antioxidant lycopene found in red fruits and vegetables such as tomatoes, apricots, pink grapefruit and watermelon may be less likely than other men to develop prostate cancer.

Lycopene has also been linked to reduced risk of developing type 2 diabetes mellitus. Lutein, found in spinach and corn, has been linked to a lower incidence of eye lens degeneration and associated vision loss in the elderly.

Research also suggests that dietary lutein may improve memory and prevent cognitive decline. Studies show that flavonoid-rich foods prevent some diseases, including metabolic-related diseases and cancer. Apples, grapes, citrus fruits, berries, tea, onions, olive oil and red wine are the most common sources of flavonoids.

Plant foods are rich sources of antioxidants. They are most abundant in fruits and vegetables, as well as other foods including nuts, wholegrains and some meats, poultry and fish.

Good sources of specific antioxidants include:. There is increasing evidence that antioxidants are more effective when obtained from whole foods, rather than isolated from a food and presented in tablet form. Research shows that some vitamin supplements can increase our cancer risk.

For example, vitamin A beta-carotene has been associated with a reduced risk of certain cancers, but an increase in others — such as lung cancer in smokers if vitamin A is purified from foodstuffs.

A study examining the effects of vitamin E found that it did not offer the same benefits when taken as a supplement. A well-balanced diet, which includes consuming antioxidants from whole foods, is best.

If you need to take a supplement, seek advice from your doctor or dietitian and choose supplements that contain all nutrients at the recommended levels. Research is divided over whether antioxidant supplements offer the same health benefits as antioxidants in foods.

To achieve a healthy and well-balanced diet , it is recommended we eat a wide variety from the main 5 food groups every day:. To meet your nutritional needs, as a minimum try to consume a serve of fruit and vegetables daily.

Although serving sizes vary depending on gender, age and stage of life, this is roughly a medium-sized piece of fruit or a half-cup of cooked vegetables. The Australian Dietary Guidelines External Link has more information on recommended servings and portions for specific ages, life stage and gender.

It is also thought antioxidants and other protective constituents from vegetables, legumes and fruit need to be consumed regularly from early life to be effective.

What You Need to Know About Antioxidants

MAX randomized placebo-controlled trial showed a reduction in cancer risk and all-cause mortality among men taking an antioxidant cocktail low doses of vitamins C and E, beta-carotene, selenium, and zinc but no apparent effect in women, possibly because men tended to have low blood levels of beta-carotene and other vitamins at the beginning of the study.

Age-related eye disease A six-year trial, the Age-Related Eye Disease Study AREDS , found that a combination of vitamin C, vitamin E, beta-carotene, and zinc offered some protection against the development of advanced age-related macular degeneration, but not cataracts, in people who were at high risk of the disease.

However, relatively short trials of lutein supplementation for age-related macular degeneration have yielded conflicting findings. The study found that people taking the vitamins were less likely to progress to late-stage AMD and vision loss.

However, the study authors noted that taking lutein and zeaxanthin alone or vitamin E alone did not have a beneficial effect on these eye conditions. The Selenium and Vitamin E Cancer Prevention Trial SELECT Eye Endpoints Study, which followed 11, men for a mean of five years, did not find that vitamin E and selenium supplements, in combination or alone, protected from age-related cataracts.

It did not find that antioxidant supplements of vitamin E or selenium, alone or in combination, protected against dementia compared with a placebo. Early death A meta-analysis of 68 antioxidant supplement trials found that taking beta-carotene and vitamin A and E supplements increased the risk of dying.

It was also difficult to compare interventions because the types of supplements, the dosages taken, and the length of time they were taken varied widely. The same authors conducted another systematic review of 78 randomized clinical trials on antioxidant supplements including beta-carotene, vitamin A, vitamin C, vitamin E, and selenium alone or in combination.

The study found that both people who were healthy and those with diseases taking beta-carotene and vitamin E supplements had a higher rate of death. The duration of the studies varied widely from one month to 12 years, with varying dosages. The first inkling came in a large trial of beta-carotene conducted among men in Finland who were heavy smokers, and therefore at high risk for developing lung cancer.

The trial was stopped early when researchers saw a significant increase in lung cancer among those taking the supplement compared to those taking the placebo. Again, an increase in lung cancer was seen in the supplement group.

MAX trial, rates of skin cancer were higher in women who were assigned to take vitamin C, vitamin E, beta-carotene, selenium, and zinc. These results came from the Selenium and Vitamin E Cancer Prevention Trial SELECT that followed 35, men for up to 12 years.

The harder and longer you exercise , the more free radicals your body produces 6. However, several studies have shown that taking antioxidant supplements — specifically vitamins C and E — can interfere with how your body adapts to exercise and even eliminate some of the health benefits associated with exercise 8 , 9 , 10 , Since antioxidants neutralize free radicals, taking antioxidant supplements have been speculated to decrease the risk of developing or dying from cancer Several meta-analyses, however, have shown that taking antioxidant supplements does neither reduce the risk of many types of cancers nor reduce the risk of dying from them once diagnosed, In fact, they may even increase the risk of certain cancers 14 , 15 , 16 , In addition, several meta-analyses have found that beta-carotene supplements, a precursor of vitamin A, increases the risk of bladder cancer, and, in people who smoke, the risk of lung cancer as well 18 , 19 , 20 , The exception is selenium , which may help prevent cancer in people with low levels of the mineral or in people with an elevated risk of cancer.

However, more research is needed before selenium can be recommended for this purpose 16 , 22 , 23 , Vitamin A is important for fetal growth and development, but at high doses, vitamin A supplements can increase the risk of birth defects 25 , Therefore, women who might be or are pregnant should not take high doses of vitamin A supplements These supplements are only recommended for pregnant women in areas where vitamin A deficiency is prevalent, such as in Africa and Southeast Asia 28 , Beta-carotene, the precursor of vitamin A, is not shown to lead to birth defects.

But since taking the supplement long-term is associated with cancer, pregnant women should consult with their physician before taking beta-carotene supplements 30 , Though antioxidant supplements are generally not recommended for a variety of reasons, the antioxidant vitamin C may benefit people with the common cold or those who smoke.

Vitamin C has not been shown to prevent the common cold , but it may reduce its severity and duration. In addition, higher doses may cause stomach upset Similarly, exposure to secondhand smoke also increases vitamin C needs Yet, this additional need for vitamin C can be easily met through diet and without taking antioxidant supplements.

For the most part, the use of antioxidant supplements is discouraged, though the antioxidant vitamin C can benefit people with the common cold or those who smoke. Still, needs can often be met through diet instead of supplements. Getting antioxidants from food rather than supplements is much safer and healthier.

While animal-based products, such as eggs and dairy products, have antioxidants, plant-based foods are particularly high in them Antioxidants are found in most foods, but plant-based sources such as fruits and vegetables are particularly rich in them.

Antioxidant supplements are commonly considered healthy but can be problematic when taken in excess. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

Some supplements can have powerful effects. Here is a list of 4 natural supplements that are just as effective as pharmaceutical drugs. Goji berries also contain unique antioxidants known as Lycium barbarum polysaccharides, which have been linked to a reduced risk of heart disease and cancer.

Moreover, there is limited research on the effects of goji berries on humans. Though these support their health benefits, more human-based research is needed. Learn about the health benefits of goji berries. Raspberries are a great source of dietary fiber, vitamin C, and manganese.

A review of five studies also concluded that the anti-inflammatory and antioxidant properties of black raspberries may slow down and suppress the effects of a variety of cancers. Plus, the antioxidants in raspberries, especially anthocyanins, may reduce inflammation and oxidative stress.

This may reduce the chance of developing heart disease. That said, most of the evidence for the health benefits of raspberries is from test-tube studies, so more human-focused research is needed.

Learn about the health benefits of raspberries. Kale is one of the most nutritious greens on the planet and is rich in calcium, and vitamins A, K, and C.

This is because red varieties of kale contain more anthocyanin antioxidants as well as several other antioxidants that give them their vibrant color. Learn about the health benefits of kale. Also known as purple cabbage, red cabbage is rich in vitamins C, K, and A, and has a high antioxidant content.

It, too, contains anthocyanins, which give it its color and may help reduce inflammation, protect against heart disease, and reduce the risk of certain cancers. That said, the volume of antioxidants in red cabbage varies depending on how you cook it. Learn about the health benefits of red cabbage.

Beans are a diverse group of legumes that are inexpensive and healthy. They are also incredibly high in fiber, which can help keep your bowel movements regular. Beans are also one of the best vegetable sources of antioxidants, containing a particular antioxidant called kaempferol, which may help with things like reducing chronic inflammation and suppressing cancer growth.

That said, most of the research supporting the benefits of kaempferol has been in animals or test tubes, so more human-based studies are needed. Learn about the health benefits of beans. Beets, also known as beetroot , are a great source of fiber, potassium, iron, folate, and antioxidants.

These give beets their reddish color and have been linked to health benefits. For example, several test-tube studies have linked betalains to a lower risk of cancers in the colon and digestive tract.

Learn more about the health benefits of beats. Spinach is loaded with vitamins, minerals, and antioxidants, and is incredibly low in calories. Learn about the health benefits of spinach.

Spices such as ginger , turmeric , and garlic , as well as herbs such as rosemary , parsley , and sage , all contain a variety of minerals, vitamins, and important antioxidants.

Putting them on your food or in your cooking can help reduce oxidative stress, which can help reduce the chance of developing various health conditions.

Depending on the specific herb or spice, these diseases include high blood pressure, heart disease, kidney disease, and diabetes. Okra is a flowering plant with edible seed pods that grows best in warm and tropical climates.

It also contains antioxidants that are anti-inflammatory and may help reduce high cholesterol and blood pressure, as well as protect heart and brain health. Read more about the health benefits of okra. That said, some have more bioactive compounds than others, such as vitamins E and C , for example.

Drinks that are high in antioxidants include green tea, pomegranate juice, and acai juice. They protect your body from potentially harmful molecules known as free radicals, which can accumulate and promote oxidative stress.

Oxidative stress raises the risk of heart disease, cancers, type 2 diabetes, and many other chronic conditions.

Antioxidants are natural or human-made substances that play a role in some cases of cell damage prevention or delay. Read on to learn more. Antioxidants are molecules present in the body and found in plant-based foods that counteract oxidative stress.

Oxidative stress happens when there are more free radicals in the body but fewer antioxidants available to remove them. Free radicals are molecules or fragments of molecules with at least one set of unpaired electrons. They try to form bonds with atoms, electrons, or molecules to become stable.

As a result, free radicals can be a byproduct of normal metabolism. They may also form in response to exercise , sun exposure, and environmental pollutants like smog and cigarette smoke. The oxidative stress triggered by free radicals damages healthy cells and is thought to play a role in a variety of diseases, including:.

Antioxidants work to protect healthy cells from free radical attacks. By doing so, they help maintain proper physiological function and guard your health. There are two major types of antioxidants: endogenous and exogenous. Endogenous antioxidants are ones that the body can produce.

They can exist as enzymes, such as catalase CAT , or in non-enzyme forms like bilirubin or uric acid. Antioxidants considered to be exogenous are ones that the body can't produce. These are the antioxidants most people may be familiar with, as they have to come from food.

Examples of exogenous antioxidants include:. Many plant-based foods provide antioxidants, so they're easy to come by. Some of the top sources include:. To take in a broader spectrum of antioxidants—as well as vitamins, minerals, and fiber—aim for various plant-based food groups of different colors.

Another way to increase your antioxidant intake is to replace processed foods with whole, plant-based foods. Also, consider the following ideas and tips for increasing antioxidant consumption:. Antioxidant supplements are dietary supplements based on antioxidants that you can get from food like selenium, vitamin C, and beta-carotene.

Just like natural antioxidants, the supplements are intended to eliminate free radicals. However, scientists have concluded that getting antioxidants from foods is better than supplements.

Antioxidant supplements tend to come in high doses. Too much of any antioxidant can be more harmful than helpful. Also, research regarding the effectiveness of antioxidant supplements has been mixed, or the supplements have not resulted in significant benefits to individuals' health in the studies.

Some research has linked high-dose beta-carotene supplement use with an increased risk of lung cancer in smokers. Taking high-dose supplements of vitamin E has been associated with an increased risk of both hemorrhagic stroke—a type of stroke caused by bleeding in the brain—and prostate cancer.

Also, drug interactions can occur between antioxidant supplements and any medications you may be prescribed. For example, a person taking blood thinners can be at increased risk of bleeding if they also take vitamin E supplements. When antioxidant levels in the body are lower than that of free radicals — due to poor nutrition, toxin exposure or other factors — oxidation wreaks havoc in the body.

The effect? Accelerated aging, damaged or mutated cells, broken-down tissue, the activation of harmful genes within DNA, and an overloaded immune system. The Western lifestyle — with its ultra-processed foods , reliance on medications, and high exposure to chemicals or environmental pollutants — seems to lay the foundation for the proliferation of free radicals.

Because many of us are exposed to such high rates of oxidative stress from a young age, we need the power of antioxidants more than ever, which means we need to consume antioxidant foods. What is an antioxidant, and why is it important?

While there are many ways to describe what antioxidants do inside the body, one antioxidant definition is any substance that inhibits oxidation, especially one used to counteract the deterioration of stored food products or remove potentially damaging oxidizing agents in a living organism.

Antioxidants include dozens of food-based substances you may have heard of before, such as carotenoids like beta-carotene, lycopene and vitamin C. Antioxidants also help neutralize harmful free radicals to prevent the potential negative effects on health.

Free radicals accumulate in the body due to oxidative stress, which can be caused by a number of different factors, including diet and lifestyle. Over time, free radicals can cause cell damage and contribute to the development of chronic disease.

Why are antioxidants good for you? Research suggests that when it comes to longevity and overall health, some of the benefits of consuming antioxidant foods, herbs, teas and supplements include:.

There are many different types of antioxidants, including several antioxidant vitamins, minerals and polyphenols. Most whole foods include a mix of the best antioxidants, making it easy to maximize the potential health benefits and fit a range of vitamins for the immune system into your diet.

Along with other compounds on the list of antioxidants, vitamin C antioxidants are highly effective at neutralizing free radicals to protect against disease. Other vitamins and minerals that have powerful antioxidant properties include vitamin A, vitamin E, manganese and selenium.

Other antioxidants include lycopene, carotenoids, lutein, zeaxanthin, anthocyanins , quercetin, glutathione and flavonoids like rutin. As described above, the single most important benefit of antioxidants is counteracting free radicals found inside every human body, which are very destructive to things like tissue and cells.

Free radicals are responsible for contributing to many health issues and have connections to such diseases as cancer and premature aging of the skin or eyes. The body uses antioxidants to prevent itself from the damage caused by oxygen.

Electrons exist in pairs; free radicals are missing an electron. This is their weapon of sorts. Free radicals then damage DNA, cellular membranes and enzymes. Many foods that provide these nutrients also supply antioxidants called lutein and zeaxanthin, nicknamed the eye vitamins , found in brightly colored foods like fruits and vegetables — especially leafy greens and types that are deep orange or yellow.

These antioxidants are believed to be easily transported around the body, especially to the delicate parts of the eyes called the macula and the lens. In fact, there are more than different types of carotenoids found in nature, but only about 20 make their way into the eyes.

Of those 20, lutein and zeaxanthin are the only two macular carotenoids that are deposited in high quantities into the macular portion of the eyes, which is one of the earliest to be damaged during aging. Research shows that high-lutein sources like spinach are proven to help decrease eye-related degeneration and improve visual acuity.

Similarly, flavonoid antioxidants found in berries, such as bilberries or grapes also great sources of the antioxidant resveratrol , may be especially beneficial at supporting vision into older age.

Perhaps most noticeably, free radicals speed up the aging process when it comes to the appearance and health of your skin. Using antioxidants for skin may help combat this damage, especially from eating sources high in vitamin C, beta-carotene and other antioxidants. Vitamin A and C have been connected to a decrease in the appearance of wrinkles and skin dryness.

Vitamin C, specifically, is a powerful antioxidant that can help reduce the effect of oxidative damage caused by pollution, stress or poor diet.

Vitamin A deficiency has also been linked to skin dryness, scaling and follicular thickening of the skin. Similarly to how free radicals damage surface skin cells, keratinization of the skin, when the epithelial cells lose their moisture and become hard and dry, can occur in the mucous membranes of the respiratory, gastrointestinal tract and urinary tract.

At this point, the data does not show that all antioxidants are effective in protecting against heart disease, but some, such as vitamin C, do seem to be.
