Vitamins B3

Supplements

Niacin or nicotinic acid is an important vitamin of the B group. It is essential for the metabolism of carbohydrate, fat and protein. It is also essential for the normal functioning of the skin, intestinal and nervous systems. Like other B-vitamins it is also lost in excess of cooking water.

This vitamin differs from the other vitamins of the B-complex group in that an essential amino acid, trytophan serves as its precursor.

The nicotinic acid or Niacin in the body gets converted rapidly to nicotinamide (before it becomes active), which is a part of coenzymes essential for the metabolism of proteins, carbohydrates and fats.

It is absorbed both in stomach and intestine and stored in all tissues. It gets excreted as salts in urine (daily 2-4 mgm) and also as free Niacin in very small quantity.

Niacin can be formed from the essential amino acid Tryptophan. The amino acid Tryptophan gets converted into Niacin in the body. 60 mg of Tryptophan would give 1 mg of Niacin.
