NAD+ 1000mg

NAD+ is not a peptide but sits alongside them in longevity research because the enzymes that consume it, particularly the sirtuins and PARP1, are central to most mechanistic accounts of cellular ageing. Tissue NAD+ declines with age, and whether that decline is cause or consequence is the question most of the field is built around. Direct NAD+ supply is one experimental approach; precursor supply through NR or NMN is the other, and comparing the two is a common design. This 1,000mg vial is the large presentation, appropriate for extended protocols where the compound is used at high molar concentration.
