The Active Ingredient Is: Nicotinamide Mononucleotide

Nicotinamide Mononucleotide, NMN, is a nucleotide-derived compound that serves as a direct precursor to NAD+, a coenzyme involved in cellular energy processes.

This form is supplied as a powder for convenient use and is widely studied for its role in cellular metabolism and healthy ageing.

What Does Nicotinamide Mononucleotide Do?

Nicotinamide Mononucleotide helps support normal energy production and metabolic function by increasing NAD+ availability in the body.

Scientific research suggests that NMN can elevate NAD+ levels and is associated with improvements in insulin sensitivity and physical endurance in adults, as described in studies conducted by Dr. Yoshino of Tokyo University using human data.
