What Is NMN?

High-Grade Ingredients For High-Performance Results
Nicotinamide mononucleotide (NMN) is a derivative of the B-vitamin niacin that dramaticallyimproves health and longevityby serving as a precursor to NAD+, a compound that plays a crucial role in energy production*, muscle regeneration*, metabolism,* and gene expression* in the body.
NMN works byreplenishing diminished NAD+ levels, which naturally fall at a rate of about 1% per year; a 50-year-old person, for example, has about half of the NAD+ they had in their youth. Why is NAD+ important? Because NAD+ is a coenzyme found in all living cells. It is required for all of the body’s fundamental biological processes and is absolutelyessential for life
