VIB3

Vitamin B3 (niacinamide) supports energy metabolism, nervous system function, and skin health. Deficiency is rare but can cause fatigue, skin rashes, and in severe cases pellagra. The Niacinamide test measures blood levels to ensure adequate intake and absorption.

Why Vitamin B3 Test (Niacinamide) Matters?

A Vitamin B3 blood test helps identify deficiencies early, allowing for timely intervention and prevention of more serious health problems such as pellagra. Ensuring optimal levels of Vitamin B3 supports metabolism, reduces inflammation, and promotes healthy skin.
