    L-Carnitine Fumarate seems to work for my CFS better than normal carnitine.

    Best L-Carnitine: side effects

    Posted by Reviewer2631717 on Feb 11, 2015

    I ordered this, as it is supposed to help burn fat, so that would mean less exercise right? Well what a shock when I saw Dr. Oz's report on it. He had a research doctor and heart specialist on his show that explained in detail how L-Carnitine is changed inside the intestines to a substance that clogs arteries and blood vessels and causes strokes and heart attacks. Dr Oz warned intensely against taking this as a supplement! I ordered 2 of these, but because I opened them, I was told they are not returnable.... my loss. Latest is that the manufacturers are onto Dr Oz: they counter his expert by saying that Carnitine is alright if you don't consume huge amounts of red meat such as steaks, roasts and hamburgers.

    Doctor's Best

    Posted by Reviewer2365100 on Dec 15, 2008

    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.
