L-Carnitine works synergistically with Co-Q10, an antioxidant and energy cofactor that is found in the inner membrane of the mitochondria.

Promotes fat loss fast

Posted by PurplePegasus on Oct 29, 2012

L-Carnitine is a top of the line amino-like product which works fast to melt body fat, however a minimum of exercise is required for this to work, whether it be walking fast or simply lifting heavy stuff around the house. I also take this for circulation problems, particularly to the brain and arms. I went from 500mg a day to 2g (from 1 pill to 4 per day) and I see better results all-around at 4 pills per day. Always safest to start slow to gauge results and potential reactions. No side effects for me at either dosage. Thanks to this and several other amino acids, I now have muscle tone again after medical steroid treatment catabolized my muscle tissue everywhere. Always take on empty stomach. This a very good brand.

This Works!

Posted by Reviewer1832232 on Jan 26, 2009

I put may wife on this for energy and weight loss. She has seen a noticeable increase in energy and has lost 5 lbs. in 2 weeks without any exercise, and she does not lose weight easily. My 18 yr. old daughter was extremley fatigued and was having a racing heart muliple times daily. Since being on this product she has much more energy and her instances of lowered heart rate has diminished. p.s. Don't take late at night they may keep you awake.

Definitely more energy!

Posted by TrueReviews on Nov 15, 2013

I started taking the supplement for weight loss purposes, after the Perricone recommendation. While I didn't notice any significant weight loss, I did notice an increase in energy. Even when I was sleep deprived I did feel better and even my mind was more alert. Another good L carnitine product is by Thorne Research: Thorne Research, L-Carnitine.

Jarrow Formula L-Carnitine

Posted by Reviewer1434920 on Feb 13, 2012

my kid with low muscle tone uses this in combination with Dr Best CoQ10 100mg - appears to work pretty well for him, more endurance and stamina now, participating in much more activities than just lazing around

updated carnitine

Posted by Reviewer1908266 on Jun 22, 2008

The chelates of carnitine change as new research reveals what functions best. Fumarate is one of the latest incarnations. I use free-form carnitine in a powder, but to tighten the dose I augment with a few capsules of the fumarate. I've used Jarrow carnitine for years, with good results.
