Niacin (Vitamin B3) is more commonly known as nicotinamide in the biochemical community and plays an important role in the biosynthesis of pyridine nucleotides. This nitrogen heterocyclic biochemical is combined in vivo with the nucleotide adenosine to form nicotinamide adenine dinucleotide (NAD), which serves as a soluble electron carrier in biochemical reactions. Common sources of niacin include cheese, beans, milk, meat, poultry, fish, eggs, whole grains, and brewer's yeast. Clinically, niacin serves to maintain normal function of the digestive system, helps to reduce cholesterol levels, and serves to reduce dizziness and ringing in the ears.
