Creator description · original language
NMN is one of the more interesting molecules being studied in aging. Here's what it actually is, what NAD+ does in the body, and where the evidence currently stands.
In this video:
· What NAD+ (nicotinamide adenine dinucleotide) is, and why every cell in your body depends on it
· NAD+'s role in energy production, DNA repair, and other biological processes connected with aging
· How NAD+ levels decline with age, and what that decline has been associated with
· Where NMN fits in — a naturally occurring molecule the body can use to support NAD+ levels
· What animal research has shown: metabolism, mitochondrial function, and physical performance
· Why human research is still developing, with studies that remain relatively small and short-term
· What we don't yet know, and why clinical trials are needed
· Why the strongest evidence for healthy aging still points to strength training, quality sleep, nutrient-dense foods, and staying socially and mentally engaged
