Also known as nicotinic acid, niacin is an essential nutrient, positioned at the core of NAD/NADH and NADP/NADPH, which are major redox-active "electron storage" compounds. One or both of these "redox pairs" is involved in every major biochemical pathway.
As a dietary supplement, 1 capsule two or three times daily with meals, or as directed by a healthcare practitioner.
Niacin can cause skin flushing and tingling (the "niacin flush"). DO NOT TAKE LARGE AMOUNTS OF NIACIN (GREATER THAN 1.5 GRAMS PER DAY) WITHOUT FIRST CONSULTING A HEALTHCARE PRACTITIONER. Keep in a cool, dry place, tightly capped.
