Vitamin B3 500 mg  product image
SKU: NF-1227

Feature Summary

Vitamin B3 essentially comes in two forms: niacin (or nicotinic acid) and niacinamide and both possess the same vitamin activity in the body. Some people prefer to take niacinamide because niacin can cause flushing, which is characterized by itching, burning, and tingling sensations of the skin. However, niacin, not niacinamide, is recommended for circulatory problems, and it has greater cholesterol and triglyceride lowering properties.

Niacin is necessary for the metabolism of carbohydrates, fats and proteins. When given in large amounts, niacin has a drug-like effect on blood cholesterol levels. It seems to inhibit the secretion of cholesterol from the liver into the circulation, and also increases the amount of high density lipoprotein, the so-called "good cholesterol".

World-renowned author and researcher, Dr. Abram Hoffer, uses very high doses of niacin to treat schizophrenia with good results.


Each tablet contains:
Vitamin B3 (nicotinic acid) .........................500 mg

Recommended Adult Dose

1 tablet daily with food or as directed by a health care practitioner. Keep out of the reach of children.


  • Niacin has been shown to potentiate the cholesterol lowering effects of other lipid-lowering drugs, especially the statin drugs like atorvastatin (Lipitor®); gemfibrozil (Lopid®); lovastatin (Mevacor®); pravastin (Pravachol®); simvastatine (Zocor®), etc.
  • Because niacin can impair glucose tolerance, it may interfere with drugs used in the treatment of diabetes.
  • Consult a health care practitioner prior to use for either of these conditions.
