This Works!

Posted by Reviewer1832232 on Jan 26, 2009 | Verified Purchase

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.

Promotes fat loss fast

Posted by PurplePegasus on Oct 29, 2012 | Verified Purchase

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.

Jarrow Formula L-Carnitine

Posted by Reviewer1434920 on Feb 13, 2012 | Verified Purchase

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 | Verified Purchase

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.

Definitely more energy!

Posted by TrueReviews on Nov 15, 2013 | Verified Purchase

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.

Feeling much better

Posted by Reviewer3089763 on Jun 24, 2012 | Verified Purchase

I've been enjoying this product a lot. It gives my much more energy, and I'm feeling much better too. 100 Vcaps last over 3 months, so price and quality ratio is great. Highly recommended L-Carnitine product.

L-Carnitine -- a workout's best friend

Posted by Reviewer2453856 on Sep 21, 2012 | Verified Purchase

I love this stuff. I do have asthma and this really helps me have the stamina that I need in order to workout. And best of all I don't get very sore after my workouts. If I use weights I always get very sore, not when I take L-Carnitine. I also really trust the Jarrow Brand. I did try another brand and it caused my sweating (i.e., body odor...GROSS). But I've have no problems with the Jarrow brand. Gives you a nice boost too for your workout.
