Life Extension Optimized Carnitine, three forms of L-carnitine, promotes heart & brain health, gluten free, non-GMO, vegetarian, 60 capsules

I have taken acetyl-l-carnitine for many years but was impressed by these additional cartinine molecules' properties to enhance neuron growth and protect endothelial cells. I take it with other brain supplements for my morning boost. [This review was collected as part of a promotion.]

This product gets the result it is intended to do

Gives me a lift physically, and mentally.

Works great , I take it in the morning before workout for energy .

I purchased Life Extension Optimized Carnitine, Magnesium Caps, Ubiquinol CoQ10 and D-Ribose Powder after the Widowmaker left me with a broken Heart and an implanted defibrillator. Life Extension is the only brand I trust, when my life actually depends on the supplements I am taking.

A great source of energy, helping convert fat into energy. I take this with a full spectrum of antioxidant, energy assisting supplements. I've used L-Carnitine supplements for several years with very good results. This is the best of all the products I've tried.

Take almost daily

Using for pain related to peripheral nerve pain. Hard to tell results yet, but have some confidence that manufacturer is good. 3 stars

Well, this was not a good product for me. But then my body clearly lets me know what supplements do not fly. after 1-3 days of use as directed I just found it too stimulating. So it was either not what was needed or my body simply could not process it.
