    Works great for reducing the size of your thyroid 1000mg to 1500mg every day. Has an added bonus of reducing lipids in blood and increasing muscle tone. GREAT PRODUCT!!

    Doctor's Best Best L-Carnitine Fumarate 855 mg.

    Posted by Reviewer2694564 on Nov 10, 2008

    I have CFS. Years ago, I was told to start taking L-carnitine, but I couldn't afford it. Thanks to the amazing price for this product, I was able to buy enough to take 4-6 gms/day for the next 6 months. I've been taking it for less than a month, but I think it's helping increase my energy. I'll update after 8 weeks. Thanks i-herb for making it possible for me to finally see if this helps.

    I've been taking the l-carnitine for about 2 weeks now and notice that it really does cut my appetite without any side effects!

    This is part of the Linus Pauling Heart protocol that got me off the prescription drugs that were killing me. Got my life back.
