This product targets cellular aging by supplying 300mg of **Nicotinamide Riboside** (NIAGEN), an NAD+ precursor that helps your body replenish the coenzyme responsible for energy metabolism, DNA repair, and sirtuin activation. At 300mg, you're above the 250mg minimum studied in humans.
NAD+ levels naturally decline as you age — research estimates roughly a 40% drop between ages 30 and 70. NR has been shown to dose-dependently raise NAD+ blood levels, and 300mg daily has demonstrated measurable increases in clinical studies.
The caveat is that most rigorous clinical trials used 1,000mg daily (often split into two doses). At 300mg, you're getting a meaningful but lower-end dose. If you're looking for the full research-backed protocol, you'd need to take more than one capsule — which makes this a 30-day supply turn into 10 days or less.
