It is a substance that normally occurs in 2 forms:
- D-carnitine
- L-carnitine
D-carnitine has no function in the human body and may even be toxic if ingested in large quantities.
L-carnitine is a substance that plays a role in the metabolic activity of the body. It is a popular nutritional supplement for weight loss, as it intensifies the conversion of fats into energy by binding fatty acids.
