I have had open heart surgery twice in the past 20 years. I have done some research and advice from my Doctor. I take the L-Carnitne, D-Ribose, Magnesium and Co-Q10 daily. This combination helps with the ATP function of the cells in the body. I was having irregular heartbearts but since being on this combination my heart beats fine and my last thallium stress test showed inprovement from a year ago. Before taking these talk to your Doctor and let him/her know what you would like to try. iHerb has the best prices I can find and service that is second to none.

Great product and the value is excellent. Advised by my Doctor to take this with magnesium and CoQ10 and L-Carnitine. I even told my Doctor about iHerb.

Cannot say enough good things about product.
