Antioxidant Supplements: Too Much of a Kinda Good Thing
There appears to be a continued public misconception (encouraged by the supplement industry) that free radicals are bad, and that antioxidants are good. Of course, like most phenomena affecting our health, it’s not that simple.
Free radicals are molecules or atoms containing an unpaired electron. Unpaired electrons are attention seekers. They really don’t like being alone, so are always searching out other electrons. This makes them highly reactive. Free radicals are like the unstable friend who shows up drunk to the party and starts breaking things. Antioxidants are molecules that are able to donate an electron to the free radical, thus stabilizing it. They’re like the patient friend…

Don’t waste your time taking antioxidant supplements after exercise
We recently published a Cochrane review which included 50 studies looking at the link between antioxidant use and reduced muscle soreness. And we discovered that there is no solid evidence that antioxidants works.
What are antioxidants? And are they truly good for us?
Antioxidants seem to be everywhere; in superfoods and skincare, even chocolate and red wine. Products that contain antioxidants are marketed as essential for good health, with promises to fight disease and reverse ageing.

The dark side of antioxidants: Fresh evidence that they fuel cancer’s spread
There is no question that antioxidants, such as those in fruits and vegetables and other foods, neutralize molecules called free radicals that can damage DNA. That has led to assertions that antioxidants can prevent cancer, since DNA damage can turn normal cells into malignant ones. But studies of whether antioxidant supplements (pills, not foods) can prevent cancer have largely disappointed.

Antioxidants: In Depth
Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Diets high in vegetables and fruits, which are good sources of antioxidants, have been found to be healthy; however, research has not shown antioxidant supplements to be beneficial in preventing diseases. Examples of antioxidants include vitamins C and E, selenium, and carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin.
More Antioxidants In Your Diet May Not Mean Better Health
Antioxidants in foods are good for you, so more should be better, right? Evidently not. In a new study, people who ate more antioxidants overall didn't lower their risk of stroke and dementia in old age. That flies in the face of earlier research that found that the antioxidants in fruits and vegetables reduce stroke and dementia risk.
Still More Evidence That Antioxidant Supplements Actually Increase Cancer Risk
Antioxidant hype was never really based on science. A handful of studies in the early '90s suggested that people will low intanks of fruits and vegetables known to be high in antioxidants were at greater risk for cancer, and the supplement industry went all out in selling the idea (it's still going all out). Follow up studies, however, focused on individual antioxidant compounds and found not much benefit. These were easily drowned out by a towering wave of antioxidant hype. Since that first wave, further research has continued to find mixed to negative results.

The Vitamin Myth: Why We Think We Need Supplements
Nutrition experts contend that all we need is what's typically found in a routine diet. Industry representatives, backed by a fascinating history, argue that foods don't contain enough, and we need supplements. Fortunately, many excellent studies have now resolved the issue.

Yes, it’s definitely a health craze but it’s unlikely going to be the last. This craze is relatively new, but the interesting thing is that antioxidants have been around a long … long … long … long time!

The role of antioxidants in the body is complex and not completely understood. Antioxidants combine with free radicals so that the free radicals cannot react with, or oxidize, other molecules. In this way, antioxidants help slow or prevent damage to cells. Damage caused by free radicals is thought to cause or contribute to cardiovascular disease, cancer, Alzheimer’s disease, age-related changes in vision, and other signs of aging. However, no direct cause and effect relationship between antioxidant intake and disease prevention has been proven. Antioxidants unrelated to those of importance in the body have commercial uses in the preservation of processed food and in many industrial processes.
