At 175mg per capsule, a single serving falls below the 250mg minimum used in human clinical trials on **NMN**. To reach the most commonly studied dose of 500mg — where benefits for cellular energy, NAD+ replenishment, and healthy aging pathways have been observed — you'd need to take three capsules daily. The good news: with 180 capsules in the bottle, even at three per day you're getting a full 60-day supply.

NMN is a direct precursor to NAD+, the coenzyme your cells rely on for energy production and DNA repair. Research in this area is still maturing — most trials are relatively small and short-term — but the evidence so far supports its role in boosting NAD+ levels, which naturally decline with age.

The main consideration is the per-capsule dose. If you stick to the label's one-capsule serving, you're getting only 70% of the minimum studied dose, which may limit the benefit you actually experience.
