NMN

Definition

Nicotinamide mononucleotide (NMN) is another direct precursor to NAD+ that efficiently crosses cell membranes to rapidly increase NAD+ levels. It is considered more bioavailable than NR.

How it works

NMN acts as a direct intermediate in NAD+ synthesis, making it potentially more effective than nicotinamide riboside for restoring depleted NAD+ levels. Several studies suggest that NMN improves mitochondrial function, insulin sensitivity, and physical performance in animals and potentially in humans. NMN is found in small quantities in various foods and can be supplemented to combat age-related NAD+ decline.

Role

NMN directly and rapidly increases intracellular NAD+ to restore energy and anti-aging functions.

Examples

• NMN supplements (250-500 mg/day) used in anti-aging trials
• NMN improves exercise performance in sedentary adults
• NMN restores blood circulation and vascular function
• NMN + exercise rejuvenates muscle mitochondria

Recommendations

Supplement with 250-500 mg of pharmaceutical-grade NMN daily, preferably in the morning. Combine with regular exercise and a polyphenol-rich diet to optimize mitochondrial regeneration and sirtuin activation.

Key takeaway

NMN is a metabolic shortcut to NAD+ that restores cellular energy and vitality lost with age.
