Why do you need vitamin B3?

Vitamin B3 is one of the B-complex vitamins, and there are three types: niacin, niacinamide and inositol hexaniacinate (also called “no flush niacin”). Niacin is important for your digestive system, skin and nervous system. It helps make sex hormones and stress-related hormones. It also helps improve circulation and suppress inflammation. Niacin is used to treat high cholesterol, and is also used alongside other treatments for circulation issues, migraines, dizziness, as well as reducing the diarrhea associated with cholera.
