Niacinamide 500 from Progressive Laboratories provides 500 mg of vitamin B3 as niacinamide per vegetable capsule.  Niacinamide (vitamin B3) is a precursor of nicotinamide adeninedinucleotide (NAD), essential for oxidation-reduction reactions, nutrient metabolism and ATP synthesis.  It does not cause the “flush” commonly associated with niacin that many find unpleasant.‡

Niacin and niacinamide are required for the proper function of fats and sugars in the body and to maintain healthy cells.  At high doses, niacin and niacinamide can have different effects.  Niacin might help people with heart disease because of its beneficial effects on clotting.  It may also improve levels of a certain type of fat called triglycerides in the blood.  Niacinamide has no beneficial effects on fats and should not be used for treating high cholesterol or high fat levels in the blood.‡

Niacin deficiency can cause a condition called pellagra, which causes skin irritation, diarrhea, and dementia.‡

Research indicates that niacinamide may support healthy glucose metabolism and protect pancreatic cell function.  In another study, niacinamide helped maintain healthy C-peptide levels and glucose metabolism.  Niacinamide also promotes joint mobility and comfort.  In a 12-week randomized double-blind trial involving 72 subjects, niacinamide provided statistically significant support for joint flexibility and normal inflammatory response.‡

People with poor diet, alcoholism, and some types of slow-growing tumors called carcinoid tumors might be at risk for niacin deficiency.‡
