Question: what is the difference between l carnitine and levocarnitine?
Answer: Levocarnitine (L-carnitine) should not be confused with the D,L-carnitine form (labeled as “vitamin B T”'). Only the L-form of carnitine is used by the body to treat serious carnitine deficiency. The D,L-form does not help the body use fat and can actually interfere with and cause a lack of levocarnitine.
