Vitamin A It is one of the fat-soluble vitamins and affects fundamental processes in the body, such as the quality of defence mechanisms, metabolism, slowing down the ageing process of the skin, the resistance of cell membranes, blood vessels, arteries and muscles. It is extremely important for eyesight and also helps maintain healthy mucous membranes and skin, as well as the normal function of the immune system. Beta-carotene is its precursor. It is converted to vitamin A in the body, and contributes to a more efficient function of metabolic, digestive and antioxidant processes in the body.
Its deficiency causes digestive problems, impairs vision, but can also cause night blindness, respiratory problems and headache. There may also be skin problems, brittle nails and dry hair.
