4 Niacin Niacin is a vitamin and  is alternatively also called as Vitamin B-3. It’s a water-soluble vitamin. Other technical names are nicotinic acid and  nicotinamide. Most dietary niacin is in the form of nicotinic acid and nicotinamide.   Ingested niacin is absorbed primarily in the small intestine while some amount is  absorbed in the stomach also. Niacin carries a number of  activities in the body. Niacin helps the body break down carbohydrates, fats and proteins into energy.  It  helps the body make sex hormones and stress-related hormones. It  improves circulation and cholesterol levels. Liver  converts a substance called ‘tryptophan’ from  protein foods like meats and milk into Niacin. Niacin increases high-density lipoprotein (HDL) cholesterol concentrations, decreases serum lipoprotein(a) concentrations.   Generally, Niacin deficiency is rare.  Mild to moderate deficiency can cause: Fatigue, depression, some times cognitive decline, digestive disturbances, localized pigmented rash.
