Our verdict

Acetyl-L-carnitine: 500 mg acetyl-L-carnitine per capsule from Jarrow Formulas. Best for acetyl l carnitine supplementation.

CapsuleJarrow Formulas

Why we recommend this

The recorded 120-capsule bottle provides 500 mg acetyl-L-carnitine per capsule. A one-capsule serving allows the product amount to be compared directly with other acetyl-L-carnitine formulas. The seller directions allow one capsule once or twice daily, so 120 servings do not necessarily mean 120 days.
