What it’s for

A long-standing gym-shelf staple for people eating less and moving more. Two forms; the tip explains which.

What to check in the listing

'L-carnitine tartrate' is the plain gym version; 'acetyl-L-carnitine' (ALCAR) is the same molecule with a small change and costs more. Check which of the two the front of the bottle means, the milligrams per capsule, and whether it is third-party tested.

Supplements are food, not medicine: nothing here treats or prevents anything. If you take any medicine, ask a pharmacist first.

FormCapsulesForm is how it arrives: something to swallow, something to stir into a drink, something to eat, or the kit that goes with them rather than a supplement itself.
PriceMid-rangePrice tier is the rough position within its category, not a live price: budget is the cheapest sensible option, premium costs more for a reason the page explains.
