journal warns against unnecessary use of antioxidant supplements -

The secular press and thousands of nutritional products warn of oxygen radicals, or oxidative stress and suggest taking so-called antioxidants to prevent or cure a disease. Professor Pietro Ghezzi at Brighton and Sussex Medical School and Professor Harald Schmidt from Maastricht University have analyzed the evidence behind this. The result is a clear warning :. Do not take these supplements unless an obvious gap is diagnosed by a health professional
Humans depend on oxygen to produce energy, but oxygen also has the potential to generate of said oxygen radicals, which can cause oxidative stress and disease. oxidative stress markers have been correlated with cardiovascular disease, cancer, diabetes and other conditions. Because of these associations, antioxidant supplements are taken by millions of people; However, none of antioxidants tested in randomized clinical trials have shown a benefit. On the contrary, some of them may cause damage. Indeed, oxygen radicals not only trigger the disease, but also perform many important functions in the body, as for the immune defense and the synthesis of hormones. Thus antioxidants will interfere with both molecules healthy and oxygen trigger diseases.
"Oxidative stress may be important in certain conditions and only in a small proportion of patients," said Professor Ghezzi. "It can be targeted in a totally different way, with targeted drugs only at the source of oxygen molecules that are triggers of the disease and allow only healthy," said Professor Schmidt. The journal is published on British Journal of Pharmacology .
