A Confident Source

Posted by iHerb Customer on Dec 19, 2010 | Verified Purchase

Having used Twinlab's Acetyl L-Carnitine for years to support my health and brain, I've found that taking amino acids seems to positively enhance how my body processes diet and exercise.

Thanks for your feedback!

ALC is a miracle supplement

Hi, I just wanted to say that ALC has helped with my depression amazingly. I have more mental and physical energy with just 500mg! I suffer from Bipolar Disorder and it's made a world of difference for me. Thanks so much for your reasonable price of it! ALC RULES!!! --Ryan

Vastly superior to other acetyl carnitine products !!

Posted by iHerb Customer on Nov 26, 2011 | Verified Purchase

This product is Carnipure brand of carnitine, made by Lonza of Switzerland. I can only assume that their quality control is better than that of other companies, because this works WAY, WAY BETTER than other brands -- particularly the Sigma Tau product (Doctor's Best) from Italy, which is inferior. All I know is that this is the stuff that works! Be sure to take it with some lipoic acid.

Thanks for your feedback!

One of my autoimmune issues is Graves Disease (hyperthyroid). When I started my anti-thyroid medication it was suggested that I take acetyl l-carnitene as well. It certainly seemed to help bring my levels back into line very quickly.

Thanks for your feedback!
