Description: Niatab 500 tablets, provided by Douglas Laboratories^®, slowly release 500 mg of pure niacin. Sustained release niacin is better tolerated than regular crystalline high-potency niacin supplements. Niatab 500 is a scored uncoated tablet which can be broken in half when lower dosage is desired.

Suggested Use: One-half to one tablet, one to two times daily during or after a meal (i.e., breakfast and dinner), or as directed by physician. As a general guideline when substituting Niatab 500 for crystalline niacin, use Niatab 500 at 1/2 to 2/3 of the level used for crystalline niacin.
