Best mix of L-Carnitine.

Posted by bodykarma on Dec 10, 2010 | Verified Purchase

Great stuff! Don't take more then 1 pill if you have a history of heart palpitations/arythmia. Otherwise, 2 pills are amazing.

Thanks for your feedback!

Good combination of acetyl and propionyl carnitines

Posted by iHerb Customer on Jul 08, 2008 | Verified Purchase

Propionyl-carnitine has demonstrated protection from endothelial vascular damage, while acetyl-carnitine has shown improvement on cognitive tasks. See the published medical research on these substances.

Thanks for your feedback!

seems to give mental/physical energy

Posted by iHerb Customer on Oct 24, 2011 | Verified Purchase

I took two the first time and my heart was racing all day. After that I took one a day. My impression is that it's slightly stimulating in that dosage. I feel noticeably more mentally/physically aroused.

Thanks for your feedback!

Significant for blood sugar problems. The numbness in my feet has improved. Chromium is also helpful.

Works well

My doctor says this is good for the brain, as well. This product works better for me than other brands as far as the muscle fatigue factor goes.
