Antioxidants are substances that block the effects of free radicals. With constant physical exertion and a varied diet, by-products of metabolism are formed in the body, which are toxic and negatively affect the structure of cells and the condition of tissues. Antioxidants neutralize the effect of such substances. As a result, recovery after training occurs faster and to a higher degree, and the training itself is more productive; progress in gaining muscle mass and increasing strength indicators is faster. In addition, in a global sense, antioxidants slow down the aging of tissues, which has a positive effect on appearance and well-being.
