Nicotinamide mononucleotide (NMN) is a precursor of NAD+ (nicotinamide adenine nucleotide) and NADH biosynthesis. Product is manufacturer in a GMP facility authenticating all products in the formula. β-Nicotinamide mononucleotide ("NMN") is a nucleotide derived from ribose and nicotinamide. NMN is a naturally occurring compound present in the body and may play an important role in how cells use energy. NMN is involved in the synthesis of nicotinamide adenine dinucleotide (NAD+), a coenzyme in cells that is essential for converting energy from nutrients into a form cells can use. NAD+ is a coenzyme involved in redox reactions. It consists of two nucleotides linked by their phosphate group. One nucleotide contains an adenine, the other a nicotinamide. It helps enzymes transfer electrons during redox reactions to form ATP and is thus an aid to energy supply. However, levels decline with age - the NAD+ in an older person's cells will have fallen by more than 50%. The mitochondria then produce less energy and cells age. Fortunately, this process may not be irreversible and intercellular energy mechanisms may be restored if levels of NAD+ are increased.
