What Trigonelline is
A natural NAD+ precursor found in coffee and fenugreek that improved muscle function in aged mice and worms and is lower in people with sarcopenia; no human intervention trial yet.
A 2024 Nature Metabolism paper identified trigonelline as an NAD+ precursor: blood levels were lower in older adults with sarcopenia, and supplementation improved muscle mitochondrial function and strength in aged mice while extending worm lifespan by about 18%. It is widely available as a supplement, and coffee is a dietary source.
Mechanism: Feeds NAD+ synthesis and supports mitochondrial function in skeletal muscle.
Regulatory history: Dietary supplement; not a drug
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 Trigonelline 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.
