Vitamin C has not been shown to prevent the common coldbut it may reduce its severity and duration.

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.

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.

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.

That said, the antioxidant content of artichokes can vary depending on how they are prepared. Learn about the health benefits of artichokes. Goji berries are often marketed as a superfood because they are rich in vitamins and minerals.

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.

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.

Another study collected numerous references demonstrating the findings of retinoic acid in protection against melanoma, hepatoma, lung cancer, breast cancer and prostate cancer. Many studies have found that people eating plant-based diets high in antioxidants, such as the Mediterranean diet , have better protection over cognition.

In addition to improving heart health and cognitive function, some research suggests that antioxidants could aid in the prevention of type 2 diabetes. For example, one animal model out of Japan showed that administering antioxidants to mice helped preserve the function of beta cells in the pancreas, which are responsible for the production of insulin.

Another large review of 12 studies found that vitamin E helped reduce blood sugar levels, while vitamin C was effective at decreasing levels of oxidative stress. Antioxidants may be easier to add to your diet than you might think. Based on ORAC scores provided by Superfoodly based on research from a broad number of sources , below are some of the top antioxidant foods by weight:.

The ORAC scores above are based on weight. This means that it might not be practical to eat high amounts of all of these antioxidant foods. Other high-antioxidant foods not listed above, which are still great sources and highly beneficial, include common foods like:.

Try to consume at least three to four servings daily of these antioxidant-rich foods even more is better for optimal health. Along with antioxidant foods, certain herbs, spices and essential oils derived from nutrient-dense plants are extremely high in healing antioxidant compounds.

Here is another list of the herbs you can try adding to your diet for increased protection against disease. Look for percent pure therapeutic grade oils, which are highest in antioxidants:. Other antioxidant-rich herbs include garlic, cayenne pepper and green tea. Aim to consume two to three servings of these herbs or herbal teas daily.

The American Heart Association, Mayo Clinic and Cleveland Clinic recommend getting antioxidants from whole foods and a wide variety of sources.

Glutathione is a peptide consisting of three key amino acids that plays several vital roles in the body, including helping with protein use, creation of enzymes, detoxification, digestion of fats and destruction of cancer cells. Glutathione peroxidase can prevent lipid peroxidation, which can fight inflammation.

Derived naturally from foods like berries and leafy greens, quercetin seems to be safe for almost everyone and poses little risk. Most studies have found little to no side effects in people eating nutrient-dense diets high in quercetin or taking supplements by mouth short term.

Amounts up to milligrams taken twice daily for 12 weeks appear to be very safe for helping manage a number of inflammatory health problems, including heart disease and blood vessel problems, allergies, infections, chronic fatigue and symptoms related to autoimmune disorders like arthritis.

Lutein has benefits for the eyes, skin, arteries, heart and immune system, although food sources of antioxidants seem to be generally more effective and safer than supplements. Some evidence shows that people who obtain more lutein from their diets experience lower rates of breast, colon, cervical and lung cancers.

Known for improving immunity, vitamin C helps protect against colds, the flu, and potentially cancer, skin and eye problems. Resveratrol is an active ingredient found in cocoa, red grapes and dark berries, such as lingonberries, blueberries, mulberries and bilberries.

Astaxanthin is found in wild-caught salmon and krill and has benefits like reducing age spots, boosting energy levels, supporting joint health and preventing symptoms of ADHD.

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.

Nutrition Journal. According to the National Center for Complementary and Integrative Health , antioxidants help prevent oxidative stress, which is thought to play a role in a number of health ailments, including cancer, cardiovascular disease, diabetes, Alzheimer's disease, Parkinson's disease and certain eye diseases.

Vitamins C and E, selenium and carotenoids are examples of antioxidants that neutralize free radicals to help counteract the harmful effects of oxidative stress on the body.

While they can be obtained from food, some people rely on antioxidant supplements to boost their antioxidant intake.

However, research shows this may not be the best thing to do for your health. Learn what antioxidant supplements are, their effectiveness and the best antioxidant-rich foods to eat. Antioxidants help prevent or delay oxidative stress from free radicals, per StatPearls.

Free radicals result naturally from exercise and converting food to energy. According to the NCCIH, certain environmental contaminants can also be a source of free radical exposure, including cigarette smoke, pollution and even sunlight.

Foods like fruits and veggies are great sources of antioxidants, but antioxidants can also be obtained through supplements. Antioxidant supplements are essentially highly concentrated doses of the given nutrient. Vitamins and minerals like vitamins C and E, selenium, manganese and carotenoids like beta carotene, lycopene, lutein and zeaxanthin are considered antioxidants, per the NCCIH.

Antioxidant supplements often come in powder, pill or liquid form. They can be purchased as a single nutrient supplement—like a vitamin C supplement—or as a multivitamin that includes a bunch of vitamins and minerals , including antioxidants.

As surprising as it may be, research does not support health benefits from antioxidant supplements, per the NCCIH. Antioxidant-rich foods , like fruits and veggies, have many health benefits, but supplements, not so much.

Even with foods, the National Institutes of Health notes that there's more to learn about the specific role naturally occurring antioxidants play and how they impact your health. 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.

These foods Antioxidant fruit supplements also been Antipxidant to Antiozidant health benefits Antioxidant fruit supplements may protect against chronic disease. Antioxidants are compounds made in the body and found in food that help defend cells from free radicalswhich can cause oxidative stress and increase the chance of developing various chronic diseases.

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.

Antipsychotic medications work by altering brain chemistry to help reduce psychotic symptoms like hallucinations, delusions and disordered thinking. No special diet or 'miracle food' can cure arthritis, but some conditions may be helped by avoiding or including certain foods.
