USE: Take with meals, as directed by a physician. 


WARNING: Niacin can cause skin flushing and tingling (the "niacin flush"). The use of niacin releases histamine from MAST cells, so for some individuals niacin may be contraindicated during the hay fever season. Niacin also can stimulate the release of stomach acid, which when uncontrolled may contribute to the initiation or exacerbation of ulcers. Thus THIS PRODUCT SHOULD NOT BE TAKEN ON AN EMPTY STOMACH. Large intakes of niacin also have been known to cause liver damage. DO NOT TAKE LARGE AMOUNTS OF NIACIN (greater than 1.5 grams per day) UNLESS UNDER THE CARE OF A PHYSICIAN. Hypoallergenic, no preservatives, diluents, chemical additives...from beef and pork sources
