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.

6.0/10
GOOD

L-Carnitine at 500mg hits the minimum effective dose but is only 25% of the optimal 2000mg. You would need 4 capsules daily to reach clinical dosing. Works at a basic level but leaves significant results on the table.
