L-Carnitine in dog food

Carnitine (L-Carnitine) is an amino acid (one of the building blocks of proteins) which as a supplement is widely recommended for dogs with heart disorders and dogs on weight loss programs. It is naturally produced by animal cells and is therefore found in small amounts in virtually all dog foods. L-carnitine has a central role in the metabolism of fats and so extra carnitine is often added to weight-loss diets as it helps to break down body fat while maintaining lean muscle mass.
