Jacob, I am so glad you tired it, I sent the wrong file by accident and sent one on Acetyl-L-Carnitine, someone was nice enought to catch my error, but I never got back to sending the right file. L-carnitine is vital for the heart, brain, and muscles. It helps with circulation to these areas, by transporting fatty acids, plus it turns over RBC, oxidation to the heart valves, and corrects errors mitochrodria DNA. If you read the article in Scientic American(august) you would have a better understanding of what I am talking about. You can get testing for carnitine deficiency, but I couldn't waste time for my dad to begin this supplement, knowing his symptoms. There is a drug(safe) called Carnitor, that is suppose to be more effective, you can ask your doctor, plus insurance should cover it. Sometimes L-carnitine can be purchased with Pantethonic Acid included, and it is an extra plus. I could see that my father was in trouble trying to switch over to Miraplex, and I had to be sure that the heart was protected. Best Wishes Linda Forrest's Mom PS Den made this discovery a while back, maybe other too. >This amino acid has made me feel so good.
