Carnipure® crystalline is pure L-Carnitine, whereas Carnipure® tartrate is the crystallized stable salt produced from Carnipure® crystalline and food-grade equivalent L-tartaric acid, in a molar ratio of 2:1 (i.e., approximately 68% L-Carnitine and 32% L-tartaric acid which is the highest L-Carnitine concentration of any currently commercially available non-hygroscopic salt form).
