C vitamin
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin, i.e. it dissolves in water, with antioxidant properties: it helps keep cells healthy by protecting them from the effects of free radicals produced during normal cellular activity. Since vitamin C is not produced by the body and cannot be stored, the right daily dose must be taken through a healthy and balanced diet. Vitamin C has a documented antioxidant activity by virtue of which it reduces lipid peroxidation, oxidative damage to DNA and that to proteins. It is useful in the prevention of cardiovascular diseases and has a chelating activity against heavy metals, becoming useful in detoxifying therapies. It can positively influence iron absorption. Vitamin C can play a protective action on eyesight and prevent cataracts. Vitamin C also contributes to the synthesis of collagen and the reduction of tiredness and fatigue and supports the normal functioning of the nervous system and psyche.
