Home Health Information Antioxidant Supplements: What You Need To Know. Antioxidant Supplements: What You Need To Know. What are antioxidants? Where do we get the antioxidants we need? Have studies been done on the health effects of antioxidants?
For example: A review of 95 observational studies, with more than 2 million total participants, showed that people who had higher intakes of fruits and vegetables had lower risks of cardiovascular disease and cancer. A study from the United Kingdom in which 72, people were followed for an average of 9 years showed that higher intakes of fruits and vegetables were associated with a lower risk of cataracts.
For example, in a study of adults living in rural areas in the United States, eating at least five servings of fruits and vegetables daily was associated with several other factors that might affect health, such as getting at least moderate physical activity and having had a routine medical exam in the past year.
Antioxidants consumed as purified chemicals might act differently than those consumed in foods, which contain complex mixtures of substances. The high doses of antioxidants in dietary supplements may have different effects than the smaller amounts in foods.
Can antioxidant supplements help to prevent cancer? Inthe U. Preventive Services Task Force, an independent panel of experts that makes evidence-based recommendations about disease prevention, recommended against the use of beta-carotene or vitamin E supplements for cancer prevention.
They also concluded that the evidence is insufficient to make recommendations about supplements of other single nutrients or pairs of nutrients. Beta-carotene supplementation led to an increase in risk of lung cancer, with the strongest evidence of an increase in risk in people at high risk of this type of cancer smokers and people with occupational exposure to asbestosas well as an increased risk of death from cardiovascular disease.

Can antioxidant supplements help to prevent cataracts? Are antioxidant supplements helpful for age-related macular degeneration AMD? A review that examined the results of 5 studies 76, participants did not find any significant benefit of vitamin E, vitamin C, or beta-carotene supplementation in preventing or delaying the onset of AMD.
For people who already have AMD, supplements containing a combination of antioxidants and zinc may slow the progression of the disease. The evidence for this comes from two large studies sponsored by the National Institutes of Health—the Age-Related Eye Disease Study AREDS and Age-Related Eye Disease Study 2 AREDS2.
AREDS evaluated the effects of a dietary supplement containing high doses of vitamins C and E, beta-carotene, zinc, and copper on the progression of AMD. Almost 4, people participated in this study, including 3, who had AMD. Among people with intermediate AMD, the supplement reduced the risk of developing advanced AMD by about 25 percent.
AREDS2 tested modifications to the original AREDS formula in about 4, people who were at high risk of progressing to advanced AMD. Participants were randomly assigned to groups that received the original formula or various modified versions.
The modifications included removing beta-carotene and adding lutein and zeaxanthin two carotenoids that are found in the eye. Because the link between beta-carotene and an increased risk of lung cancer in smokers was known before this study started, current smokers were not assigned to groups that received beta-carotene; only nonsmokers and former smokers were included in those groups.
After 10 years of follow-up, lutein and zeaxanthin proved to be more effective than beta-carotene in reducing the risk of progression to advanced AMD. Beta-carotene increased lung cancer risk among former smokers, but lutein and zeaxanthin did not.

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.

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. Lung disease A study from the Journal of Respiratory Research found that different isoforms of vitamin E called tocopherols had opposing effects on lung function. Cancer When it comes to cancer prevention, the picture remains inconclusive for antioxidant supplements.
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.

However, others can damage cells and contribute to conditions such as heart disease and some cancers. Most of us can get all the nutrients we need from food, rather than taking supplements.
Vegetables and fruit tend to be packed full of antioxidants. Eating a wide variety of them can help ensure you get a diverse range of different antioxidants to optimise your health.
There are hundreds of antioxidants in not only fruit and vegetables, but nuts, seeds, olive oil and wholegrains. The Australian Dietary Guidelines outline the types of foods you should be eating to reduce your risk of diet-related conditions and chronic diseases.
In some cases, your doctor may recommend you take antioxidant supplements if your diet is inadequate. The only reason to take supplements is if you have a deficiency.
For example, vegetarians might need iron or vitamin B12, or people with osteoporosis might need extra calcium and vitamin D. If you follow a healthy balanced diet, and you have no vitamin deficiencies, adding antioxidant supplements is unlikely to make any difference to your health.
Rigorous scientific studies involving more than , people tested whether antioxidant supplements played a role in preventing chronic diseases, like cardiovascular diseases, cancer, and cataracts. In most instances, supplementing with antioxidants did not reduce the risks of developing these diseases.
In fact, some supplements can be toxic in large doses, interact with other medications, and can actually increase the risk of developing certain diseases.
There are no current concerns about the levels of antioxidants we consume in food. Antioxidant foods for healthy glowing skin: Eat your way to better looking skin. You can find antioxidant supplements in different forms, including multivitamins, antioxidant blends, tablets, vitamins, gummies and powders to mix into drinks or sprinkle on foods.
