Product information for Klean Labs Niacinamide 500 mg: Application of Klean Labs Niacinamide 500 mg: Vitamin B3 occurs naturally in the body in two forms: niacin (nicotinic acid) and niacinamide (nicotinamide). The body can produce niacinamide from niacin.Vitamin B3 is a precursor to the metabolically active coenzymes NAD (nicotinamide adenine dinucleotide) and NADP (NAD phosphate). NAD and NADP play extensive roles in the electron transport chain and oxidation-reduction reactions. At least 200 enzymes depend on these vitamin B3 cofactors. In vivo studies show that niacinamide plays a key role in cellular energy and in improving energy-dependent cellular functions, such as DNA repair. Regardless of its functions as NAD or NADP, niacinamide can support skin and joint health, as well as proper glucose metabolism.Niacinamide may be a useful dietary supplement for people looking to improve their niacinamide intake.Composition of Klean Labs Niacinamide 500 mg: Each capsule contains:Vitamine B3 (niacinamide) 500 mgIngredients of Klean Labs Niacinamide 500 mg: Niacinamide, capsulehuls (vulstof hydroxypropylmethylcellulose).Usage of Klean Labs Niacinamide 500 mg: Take 1 capsule per day, unless otherwise advised by your health professional.Do not exceed the recommended daily dose.A varied, balanced diet and a healthy lifestyle are important.Klean Labs nutritional supplements are not a substitute for a healthy lifestyle and a balanced diet, but can be a useful addition.
