What is Vitamin B3?

Vitamin B3

Vitamin B3 or Niacin is one of the vitamin B group members and it is an essential substance for the body. Niacin is one of the three forms of this vitamin. Vitamin B3 is involved in proper cell metabolism, DNA synthesis and repair, proper functioning of the nervous system and conversion of micronutrients into energy. Vitamin B3 is water-soluble, meaning the body cannot store it, and the excess niacin will be excreted in the urine.

Vitamin B3 deficiency

People who their nutrition are limited in variety and quantity due to illness, poverty, or the unavailability of natural foods, are prone to vita‌min B3 deficiency. Also countries that use corn as a staple food, can get Pellagra (a skin disease caused by a lack of niacin in the body). Alcoholism reduces the absorption of B vitamins, including niacin. Carcinoid syndrome converts the vitamin niacin into serotonin and causes niacin deficiency in the body.
