L-Carnitine Benefits

Does L-Carnitine Work?

L-Carnitine works in various ways, including assisting with the heart, mental focus (especially for ADHD patients), and pain tolerance, but has not been shown to assist with weight-loss:

L-Carnitine for Weight-Loss:
Although L-carnitine has been marketed as a weight loss supplement, there is no scientific evidence to show that it improves weight loss. (source)


L-Carnitine for the Heart:
L-carnitine is useful for the treatment of congestive heart failure.

L-Carnitine for Focus and ADHD:


L-Carnitine for Treating Pain:
A completely different study shows that Acetyl-L-Carnitine is effective... in reducing pain over a 1-year period.


Note that some of these reference Acetyl-L-Carnitine, and some are with normal L-Carnitine. These are two different products, and you should check the label to get the right one for you.
