Niacitol® contains inositol nicotinate, a form of no-flush niacin (vitamin B3) that has been used in Europe for over 30 years to support healthy nutrient metabolism. Niacitol® is a well-tolerated form of vitamin B3 and is unlikely to cause the flushing (redness, warmth and itching of the skin) or other side effects that are associated with niacin. Inositol nicotinate is composed of one molecule of inositol and six molecules of niacin. Niacin is a key component involved in nearly all aspects of energy metabolism. It's coenzymes (NAD and NADP) are the most important electron transport carriers in cells, and assist in the metabolic processes surrounding the breakdown and utilization of macronutrients. More than 200 metabolic reactions require the presence of niacin, including those involved in glycolysis, the Krebs cycle and β-oxidation of fatty acids.
