Niacin is a water-soluble B vitamin – and the common name for two very different compounds: nicotinic acid and niacinamide. Like all B-vitamins, niacin plays a role in many aspects of energy metabolism (as a component of NAD) and nervous system function. One of the most common uses for supplemental niacin is cholesterol regulation. Rich dietary sources of niacin include many high-protein foods such as meat, chicken, tuna and other fatty fish, peanuts, pork and milk.
Claims:
- Lowers Cholesterol & Triglyceride Levels (Niacin)
- Prevents / Treats Diabetes (Niacinamide)
- Improves Circulation (Inositol Hexaniacinate)
- Relieves Arthritis (Niacinamide)
Theory:
Because niacin is involved in the proper functioning of more than 200 metabolic enzymes, it plays a role in a wide range of bodily processes, including synthesis of hormones and blood cells and the release of energy from fats, carbohydrates and proteins.
As a nutrient (vitamin B3) consumed at low doses (20-40mg), there is virtually no difference between the different chemical forms of niacin. In the mid-1950s, however, it was shown that high doses of niacin (as nicotinic acid) could lower cholesterol levels (although the exact mechanism of action is still not known).
The other form of niacin (nicotinamide or niacinamide) does not provide a cholesterol-lowering effect, but there is some evidence that it may be helpful in preventing the development of childhood diabetes (Type I) in high-risk children. It should be cautioned that there is a strong possibility of liver inflammation with large doses of any form of niacin (see safety considerations below).
