NAD+

Nicotinamide Adenine Dinucleotide (NAD+) is a vital coenzyme found in every living cell, acting as a central hub for energy metabolism and cellular maintenance. It exists in two forms: NAD+ (oxidized) and NADH (reduced), which facilitate the transfer of electrons during the production of ATP (adenosine triphosphate). Because NAD+ levels naturally decline by as much as 50% between the ages of 40 and 60, supplementation typically focuses on 'NAD+ boosters' or precursors—most notably Nicotinamide Riboside (NR) and Nicotinamide Mononucleotide (NMN)—which are more effectively absorbed and converted into NAD+ within the body than direct oral NAD+ molecules.
