Initially, neurological changes such as anxiety, poor concentration, fatigue, and depression can manifest, but as pellagra advances, dementia, and delirium may occur. Also, Niacin deficiency causes burning in the mouth and a swollen, bright red tongue.

Should You Supplement?
Everyone needs niacin, but most people can get enough from their diet alone. However, if you are deficient or have another condition that may benefit from higher doses, your doctor may recommend a supplement; but remember that at high doses niacin can be toxic; so you should not take doses higher than the Recommended Daily Allowance (RDA) except under your doctor’s supervision.
