Vitamin B3 (Niacin)

Vitamin B3 (Niacin)

Vitamin B3 or niacin is a supplement used to treat a deficiency (deficiency) of vitamin B3 or pellagra. In addition, this supplement can also be used in the treatment of dyslipidemia.

The need for vitamin B3 can actually be met by regularly consuming milk, rice, eggs, whole wheat bread, fish, lean meat, nuts, yeast, and green vegetables. However, when a person is malnourished, addicted to alcohol, or has a carcinoid tumor, the risk for vitamin B3 deficiency increases.

Niacin plays an important role in maintaining healthy skin, nerve cells, and the digestive system. In lowering cholesterol levels, vitamin B3 works by reducing the production of proteins that transport cholesterol in the blood. Vitamin B3 is water soluble so it is excreted in the urine and cannot be stored in the body.
