NOT a fat burner!
By kopkojohn from Greensburg, PA on 6/9/2011
Cons:
Not Effective
Bottom Line:
No, I would not recommend this to a friend

Comments about GNC GNC L-Carnitine 500:

To everyone buying L-carnitine to burn fat and increase energy, there is absolutely no evidence in the scientific literature that short or long term oral adminisration of L-carnitine increases metabolic rate or energy production, especially in young healthy adults. If you are reporting that this product is giving you more energy, you are almost definitely experiencing a placebo effect.

Great for hyperthyroid symptoms

Great for hyperthyroidism
Best Uses:
Daily Use
Bottom Line:
Yes, I would recommend this to a friend

Comments about GNC GNC L-Carnitine 500:

I use this product daily to control my hyperthyroid symptoms. At 750 mgs per day, my thyroid stays in normal range. My hair stopped falling out and joint pain went away. Taking this supplement daily keeps me off of thyroid medicine and all the negative side affects of those drugs.

Comments about GNC GNC L-Carnitine 500:

Well where to begin... It began with my quest to burn fat, and I was looking at a bunch of fat burners, and what I found in common with all of those is that they were caffeine-pumped thermogenics. Although a thermogenic assists with raising core temperature which in turns "helps" increase sweating, and raising metabolic rate, it does not solve the problem. Weight loss is an extremely broad spectrum, and can be achieved in MANY ways. That's a completely different topic... L-Carnitine works synergistically with B vitamins in transporting long chain fatty acids (fat deposits) to the mitochondria for oxidation (use/burning/etc). On the other hand, the B-Vitamin complex does the same for carbohydrates. With both, you feel a NATURAL increase of energy. The energy provided comes all from within. When coupled with a moderate to rigorous training routine, and proper diet, results are phenomenal, bar none!!

DO YOUR RESEARCH!!!

By rabbi2442 from Minnesota on 11/19/2010

Comments about GNC GNC L-Carnitine 500:

The bottle says take daily, but I've found that when I take it for 4 or 5 days in a row, I get pimples because of it.

I never get pimples, so I'm confident in attributing these pills with it. Especially because they were in odd locations. The first time, I got a few on my forearms, and even one on my knee, as well as my back and face. The other 2 times I've taken it in the morning with my multi for several consecutive days, I've gotten ones of my face and arms again.

That being said, I usually take one 30 minutes before I work out and they do help me feel better, both with recovery and I feel like I burn more calories too. I like this product minus the small, odd side-effect. I'd suggest trying it as a daily and see if you have the same problem I do. If not, proceed, and if you do then just use it before workouts.
