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 FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
