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 supplementation combined with aerobic training does not promote weight loss in moderately obese women.
- L-carnitine supplementation led to a significant increase in fat oxidation without changing protein breakdown rates.
- While L-Carnitine has been shown to oxidize fat, as mentioned above, L-Carnitine has not been shown to promote weight loss.
L-Carnitine for the Heart:
L-carnitine is useful for the treatment of congestive heart failure. L-Carnitine for Focus and ADHD:
- Studies have promise in L-Carnitine treating aggressive behavior in boys with ADHD, showing that marketing claims of L-Carnitine as a "focus drug" are legitimate.
- Another study on ADHD showed that patients still required treatment, but there was significant moderation in the inattentive type of ADHD with Acetyl L-Carnitine.
L-Carnitine for Treating Pain:
A completely different study shows that Acetyl-L-Carnitine is effective... in reducing pain over a 1-year period.
