L carnitine 500 mg weight loss supplement 60 capsules metabolism booster healthy
Carnitine is a type of amino acid that benefits energy levels by transporting fatty acids into the mitochondria where they can be burned up and used as fuel. For this reason, many take carnitine as a weight loss supplement to help bump up fat burning. Carnitine occurs in two forms, or isomers: L-carnitine and D-carnitine.
