Niacinamide, also known as vitamin B-3, functions in over 50 metabolic reactions, most of which are enzymatic. Its bioactive forms - NAD+, NADH, NADP, and NADPH - play important roles as catalysts in the energy production process in the cells, the breakdown of proteins and fatty acids, the synthesis of fatty acids, and the formation of steroid hormones and red blood cells.* Rejuvenation Science® NAD+ Boost is prepared to provide a gradual release over approximately a 6-hour period of time.*
