Description and Uses
Niacin is an additive to food on the basis of its nutrient supplement qualities as a vitamin (as an enzyme co-factor). This water-soluble vitamin of the B complex occurs in various animal and plant tissues. It is required by the body for the formation of coenzymes NAD and NADP. A deficiency of niacin results in the disease, pellagra.
Nicotinic acid is also known as niacin and vitamin B3. It is a water-soluble conditioning agent that improves rough, dry, or flaky skin, helping smooth the skin and improve its suppleness. niacin enhances the appearance and feel of hair, by increasing body, suppleness, or sheen, or by improving the texture of hair that has been damaged physically or by chemical treatment. When used in the formulation of skin care products, niacinamide and niacin enhance the appearance of dry or damaged skin by reducing flaking and restoring suppleness.
