What NMN is
A direct NAD+ precursor studied for metabolic and physical-function benefits in aging, with early human trials and a contested regulatory status in the US.
NMN is a precursor the body converts into NAD+. Animal studies reported improvements in insulin sensitivity, endurance, and age-related decline, and early human trials have examined insulin sensitivity, muscle function, and biomarkers with modest results.
Mechanism: Converts to NAD+ through the salvage pathway, aiming to restore NAD+ levels that decline with age.
Regulatory history: Not an approved drug; US supplement status contested
How MHRA treats this kind of product
Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency listings for NMN at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
