Lamberts® l-carnitine is in a form that is ready to be absorbed by the body without needing to be broken down by digestive enzymes. Each capsule provides a full 500mg of pure l-carnitine provided by 745mg of a compound called l-carnitine l-tartrate. Some companies label their product as if this compound is 100% l-carnitine but it is actually only 67% l-carnitine. However lamberts® does it correctly and our product is made in the uk to pharmaceutical gmp standards. Carnitine is one of the most popular amino acid supplements and because the raw material is relatively expensive we advise some caution when choosing l-carnitine supplements particularly imported products. Lamberts quantity – 60 capsules l-carnitine 500mg.
