Common Symptoms Of A Niacin Deficiency

A niacin deficiency is a rare condition that happens when an individual cannot properly absorb niacin or its precursor amino acid, tryptophan. Niacin is also known to be called nicotinic acid and vitamin B3. As one of the eight B vitamins, niacin is imperative to the syntonization of carbohydrates into glucose, preserving nervous system health, and metabolizing proteins and fats. Niacin also positively affects circulation and cholesterol. The amino acid tryptophan is important when it comes to niacin because the liver has the ability to convert it into niacin from protein-rich foods such as milk and meats.
