What this source says

Systematic review/meta-analysis of NMN and NR effects on skeletal muscle outcomes.

Why it matters

This source is part of LHN's nad and supplements evidence trail. Reading the original helps separate what the source actually addresses from broader online claims.

What it does not prove

Muscle outcomes are not lifespan outcomes and may not generalize to every supplement claim.

How LHN is using it

This brief records the source in the public evidence trail and links to the original. It does not turn a paper, registry entry or regulatory document into personal medical advice. The source's design, population and stated limitations still determine what conclusions are reasonable.
