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.

Getting Your Antioxidants from Food. Frequently Asked Questions. The Bottom Line. Trending Videos. What Happens to Your Body When You Take Vitamin D Every Day. Was this page helpful? Thanks for your feedback! Tell us why! Certain plant-based foods are thought to be rich in antioxidants.

Plant-based antioxidants are a kind of phytonutrient, or plant-based nutrient. The body also produces some antioxidants, known as endogenous antioxidants.

Antioxidants that come from outside the body are called exogenous. Free radicals are waste substances produced by cells as the body processes food and reacts to the environment. If the body cannot process and remove free radicals efficiently, oxidative stress can result. This can harm cells and body function.

Free radicals are also known as reactive oxygen species ROS. Factors that increase the production of free radicals in the body can be internal, such as inflammation , or external, for example, pollution, UV exposure, and cigarette smoke. Antioxidants are said to help neutralize free radicals in our bodies, and this is thought to boost overall health.

Antioxidants can protect against the cell damage that free radicals cause, known as oxidative stress. Activities and processes that can lead to oxidative stress include :. The damage caused by oxidative stress has been linked to cancer, atherosclerosis , and vision loss.

It is thought that the free radicals cause changes in the cells that lead to these and possibly other conditions. Other research has indicated that antioxidant supplements may help reduce vision loss due to age-related macular degeneration in older people.

Overall, however, there is a lack of evidence that a higher intake of specific antioxidants can reduce the risk of disease. In most cases, results have tended to show no benefit, or a detrimental effect, or they have been conflicting.

There are thought to be hundreds and possibly thousands of substances that can act as antioxidants. Each has its own role and can interact with others to help the body work effectively. Flavonoids, flavones, catechins, polyphenols, and phytoestrogens are all types of antioxidants and phytonutrients, and they are all found in plant-based foods.

Each antioxidant serves a different function and is not interchangeable with another. This is why it is important to have a varied diet. To obtain some specific antioxidants, try to include the following in your diet:.

Vitamin C : Most fruits and vegetables, especially berries, oranges, and bell peppers. Vitamin E : Nuts and seeds, sunflower and other vegetable oils, and green, leafy vegetables. Beta-carotene : Brightly colored fruits and vegetables, such as carrots, peas, spinach, and mangoes.

Lutein : Green, leafy vegetables, corn, papaya , and oranges. Selenium : Rice, corn, wheat, and other whole grains, as well as nuts, eggs, cheese, and legumes. Goji berries and many other food products that contain antioxidants are available to purchase online.

The following foods are good sources of antioxidants. Click on each one to find out more about their health benefits and nutritional information:. Lycopene is the antioxidant that gives tomatoes their rich red color. When tomatoes are heat-treated, the lycopene becomes more bio-available easier for our bodies to process and use.

However, studies have shown that cauliflower, peas, and zucchini lose much of their antioxidant activity in the cooking process. Keep in mind that the important thing is eating a variety of antioxidant-rich foods, cooked and raw.

There is no set recommended daily allowance RDA for antioxidants, but a high intake of fresh plant-based produce is considered healthful. It is worth remembering that, while studies link the consumption of fruits and vegetables with better overall health, it is not clear whether how far this is due to the activity of antioxidants.

In addition, caution is needed regarding supplements. The National Institutes of Health NIH warn that high doses of antioxidant supplements can be harmful. A high intake of beta-carotene, for example, has been linked to an increased risk of lung cancer in smokers.

A high dose of vitamin E has been found to increase the risk of prostate cancer , and the use of some antioxidant supplements has been linked to a greater risk of tumor growth.

Antioxidant supplements may also interact with some medications. It is important to speak with a health provider before using any of these products. Overall, research has not proven that taking any particular antioxidant as a supplement or through a food can protect against a disease.

There may be some benefit for people at risk of age-related macular degeneration, but it is essential to seek advice from a doctor about whether to use supplements, and which ones to use. Free radicals have been linked to a range of diseases, including heart disease, cancer, and vision loss, but this does not mean that an increased intake of antioxidants will prevent these diseases.

Antioxidants from artificial sources may increase the risk of some health problems. As a result, it is important to seek out natural sources of antioxidants, in the form of a healthful diet.

Consuming fruits and vegetables has been linked to a lower rate of chronic diseases, and antioxidants may play a role. However, it is unlikely that consuming added antioxidants, especially in processed foods, will provide significant benefits.

In addition, anyone considering taking antioxidant supplements should speak to a health provider first. Read the article in Spanish.

Free radicals are unstable atoms that can cause damage to cells and lead to illnesses and the aging process.

We do know, however, that higher fruit and veggie consumption is linked with reduced risk of cardiovascular disease per a study in the Journal of the American Heart Association , lower mortality per a study in Circulation and breast cancer per a study in the British Journal of Cancer , to name a few of their health benefits.

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 NIH , these 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 chocolate , green 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.

The process of oxidation in the human body damages cell membranes and other structures, including cellular proteins, lipids and DNA. The body can cope with some free radicals and needs them to function effectively.

However, the damage caused by an overload of free radicals over time may become irreversible and lead to certain diseases including heart and liver disease and some cancers such as oral, oesophageal, stomach and bowel cancers. Oxidation can be accelerated by stress , cigarette smoking , alcohol , sunlight, pollution and other factors.

Antioxidants are found in certain foods and may prevent some of the damage caused by free radicals by neutralising them. These include the nutrient antioxidants, vitamins A, C and E, and the minerals copper, zinc and selenium.

Other dietary food compounds, such as the phytochemicals in plants, are believed to have greater antioxidant effects than vitamins or minerals.

These are called the non-nutrient antioxidants and include phytochemicals, such as lycopenes in tomatoes and anthocyanins found in cranberries. A diet high in antioxidants may reduce the risk of many diseases including heart disease and certain cancers.

Antioxidants scavenge free radicals from the body cells and prevent or reduce the damage caused by oxidation. The protective effect of antioxidants continues to be studied around the world.

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.

Selenium is a trace mineral found naturally in the soil that also appears in certain foods, and there are even small amounts in water. Selenium benefits adrenal and thyroid health and helps protect cognition. It may also fight off viruses, defend against heart disease and slow down symptoms correlated with other serious conditions, like asthma.

Chlorophyll is very helpful for detoxification and linked to natural cancer prevention, blocking carcinogenic effects within the body, and protecting DNA from damage caused by toxins or stress.

Cooking can alter the content of antioxidants in food, and certain cooking methods can have a different impact on antioxidant levels. One study published in Preventive Nutrition and Food Science evaluated the effects of different cooking methods on the antioxidant content of red pepper to determine which methods can help minimize antioxidant loss.

Interestingly, researchers found that stir-frying and roasting helped retain the most antioxidants, while boiling and steaming caused significant reductions in antioxidant levels.

Ascorbic acid, also known as vitamin C, is a water-soluble vitamin, which means that it dissolves in water. For this reason, cooking food in water with methods like boiling can cause a huge reduction in antioxidant content. However, not all compounds on the antioxidants list are affected in the same way by cooking.

For example, one study found that consuming tomatoes cooked in olive oil significantly enhanced levels of lycopene in the blood by up to 82 percent compared to a control group. Similarly, another study in British Journal of Nutrition showed that stir-frying carrots significantly boosted the absorption of beta-carotene.

For example, because during exercise oxygen consumption can increase by a factor of more than 10, taking high doses of antioxidants might interfere with proper exercise recovery. When it comes to protection against things like cancer or heart disease, overall the medical literature seems conflicting.

Although some studies found a positive relationship between antioxidant supplementation and risk reduction, others have not found such positive effects. Popular Nutrition Posts All Time This Week {position} Detox Your Liver: A 6-Step Liver Cleanse. More Nutrition Dr. Axe on Facebook 82 Dr.

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.
