The Science
NAD+ declines with age. NMN can help restore it.
Nicotinamide Adenine Dinucleotide (NAD+) is a coenzyme present in every living cell. It's essential for cellular energy production, DNA repair, and gene expression regulation.
Research shows NAD+ levels decline by approximately 50% between ages 40 and 60. NMN (Nicotinamide Mononucleotide) is a direct biosynthetic precursor — the body converts NMN into NAD+ through a well-characterised enzymatic pathway.
ZENOA NMN uses a delayed release HPMC capsule designed to bypass stomach acid degradation and deliver intact NMN to the small intestine.
