antioxidant supplements

The study analyzed data from the Coronary Artery Risk Development in Young Adults (CARDIA) cohort and measured serum levels of alpha- and gamma-tocopherol in 4,526 adults. In the Heart Outcomes Prevention Evaluation (HOPE) trial, the rates of major cardiovascular events were essentially the same in the vitamin E (21.5%) and placebo (20.6%) groups, although participants taking vitamin E had higher risks of heart failure and hospitalization for heart failure. Earlier large vitamin E trials, conducted among individuals with previously diagnosed coronary disease or at high risk for it, generally showed no benefit.

At the study's end, the rates of major cardiovascular events and cancer were no lower among those taking vitamin E than those taking the placebo. Antioxidant supplements and disease prevention: little supportive evidence. These mostly disappointing results haven't stopped food companies and supplement sellers from banking on antioxidants (best antioxidant foods, antioxidant foods, natural antioxidants, chokeberry juice, black chokeberry, superfood berry, chokeberry, most powerful antioxidant, aronia fruit, aroniaberry, aronia berry, best antioxidant fruits, superfood berry). One study even showed that taking beta-carotene supplements actually increased the chances of developing lung cancer in smokers. Supplement makers touted the disease-fighting properties of all sorts of antioxidants. Clinical trials began testing the impact of single substances in supplement form, especially beta-carotene and vitamin E, as weapons against chronic diseases.

Antioxidants came to public attention in the 1990s, when scientists began to understand that free radical damage was involved in the early stages of artery-clogging atherosclerosis. Health benefits of antioxidants: what's the buzz? There are hundreds, probably thousands, of different substances that can act as antioxidants.

These defenders are labeled antioxidants. They work by generously giving electrons to free radicals without turning into electron-scavenging substances themselves. The body generates free radicals as the inevitable byproducts of turning food into energy. The body's trillion or so cells face formidable threats, from lack of food to infection with a virus.
