Tablets slowly release 500 mg of pure niacin (nicotinic acid) over 2 to 3 hours to reduce uncomfortable flushing or itching. Sustained-release niacin is better tolerated than regular crystalline high-potency niacin supplements. This product can also be broken in half when a lower dosage is desired.
