NMN in humans: trials measured aerobic capacity, NAD⁺ and muscle function, not lifespan
The description says NMN 'reverses aging' claims come from mice; human trials measured aerobic capacity, blood NAD⁺ and muscle function, and no trial has tested whether NMN extends lifespan. [1]

Mouse origin of the 'reverses aging' claim
The description states that longevity influencers claim NMN 'reverses aging', but that this claim comes from mice. It cites a 2016 mouse study on long-term nicotinamide mononucleotide administration and age-associated physiological decline, and labels it foundational animal data, not human data.

What human trials measured: aerobic capacity, NAD⁺, muscle
According to the description, human trials measured aerobic capacity, blood NAD⁺ levels and muscle function. It cites a randomized, double-blind study in amateur runners reporting enhanced aerobic capacity, a study in healthy older men reporting elevated blood NAD⁺ and altered muscle function, and a 2024 systematic review and meta-analysis of randomized controlled trials on glucose and lipid metabolism in adults.

Lifespan question remains untested in humans
The description says the one result — whether NMN extends lifespan — has not been tested by any trial. It also states this is not medical advice. The description does not report sample sizes, follow-up durations or effect sizes, and the video and transcript were not reviewed.
