NOW L-Carnitine 500mg

Energy metabolism and exercise recovery. Most studies showing benefits for fat metabolism or recovery use 2,000mg or more. This 500mg dose is only a quarter of that target. It's a fine starting point for general health, but athletes will find it lacking. You're better off buying a higher-potency version.

6.4/10
GOOD

Pure and reliable source, but you'll need four capsules to reach a clinical dose.
