L-Carnitine / L-Tartrate

L-carnitine is a chemical similar to an amino acid that is produced in the body.
L-carnitine helps the body turn fat into energy. The body can convert L-carnitine to other
chemicals called acetyl-L-carnitine and propionyl-L-carnitine. But, no one knows whether the
benefits of these other carnitines are the same. Until more is known, don’t switch one form of carnitine for another.

L-carnitine is taken by mouth to increase L-carnitine levels in people whose natural level of L-carnitine is too low.
Some people also use L-carnitine for conditions of the heart and blood vessels, overactive thyroid, inability to
become pregnant within a year of trying to conceive (infertility), serious kidney disease, and many other conditions, but there is no good scientific evidence to support these uses
