Niacin helps prevent pellagra, a serious disease combining signs of skin, digestive, psychic and haematological disorders. In dogs and cats it contributes to skin health and a hair sheen.
Vitamin PP is so named because it prevents pellagra in humans. Pellagra is a disease that makes the skin rough. A niacin deficiency in dogs causes dermatitis around the abdomen and the hindlegs, which may appear when the food is low on animal ingredients and group B vitamin supplements.
The activation of niacin helps the body complete all the oxidoreduction reactions that are essential to the production of energy from fats and sugars.
