NAD+ is required not only for life but for a long life. Implicated is the decline of NAD+ during aging, and for combating age-related diseases.
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme existing in all cells but latest research is proving NAD+ declines during the aging process to nil in our very late years. Although NAD+ loss is part of the aging process, scientists like Harvard-based David Sinclair, studying human longevity, have identified the precursor enzyme NMN (Nicotinamide mononucleotide) as a suitable replacement for NAD+, which can be taken as an oral supplement.
Some feel these are simply baby steps in the study of human longevity, and others believe we are bounding towards uncovering the real fountain of youth. Understanding what NAD+ is and why we lose it, is the key to the beginning of unlocking our own mortality.
