Douglas Laboratories: Niacin 100 mg
Niacin 100 mg by Douglas Laboratories provide 100 mg of pure niacin in a scored uncoated tablet which can be broken in half when lower dosage is desired. The NAD-dependent enzymes are involved in mostly catabolic, oxidative reactions that release energy from carbohydrate, fat, and protein, whereas the NADP-dependent enzymes more commonly function in biosynthetic pathways of such compounds as fatty acids and steroid hormones.
Niacin is also involved in the regulation of normal blood lipoprotein and cholesterol levels. Dietary niacin is generally well absorbed and taken up by the liver which converts it to NAD and NADP. Any excess niacin is metabolized by the liver and excreted by the kidneys.
