Supports NAD+ levels that decline with aging. There is some evidence that NAD+ may be directly transported into cells to a much smaller extent than its popular precursor NMN. Nonetheless, NAD+ supports the NAD pool either by direct absorption, or first degraded to NMN before entering cells.
Pure NAD+ Nicotinamide Adenine Dinucleotide is a crucial co-enzyme that declines with age. NAD+ is responsible for DNA Repair, Longevity gene regulation, and energy metabolism. Though NMN, the direct precursor to NAD+, is considered the best option for increasing NAD+ levels, NAD+ is not without its merits.
