    国内炒的很热的左旋肉碱

    Posted by xiaobeimama on Mar 06, 2013

    一直想买点减肥产品,对国内的左旋肉碱不放心啊!都是广告闹的。iherb上保健品放心些,还没开始吃。效果暂不评论。

    Great fat burner especially in winter

    Posted by robdee on Feb 04, 2013

    This is the great value for money super high quality product that I use in winter to help keep warm as it aids in cellular metabolism of fats (fat burning).

    I haven't noticed any difference

    Posted by Reviewer1581364 on Jan 21, 2013

    I bought this because I read reviews from people with Chronic Fatigue Syndrome who say this gives them energy. I suffer from depression and have low energy so I thought, if this works for people with CFS, it should work for me. But no, I've been taken it for about 4 weeks and I don't feel any different. As far as weight loss, no weight loss either.

    Don't take if you have thyroid problems!

    Posted by Reviewer2002330 on Nov 08, 2012

    I didn't do enough research before buying this product. My thyroid gland whas been removed, so I'm taking thyroid hormone replacement meds, and according to some sources, which I found only afterwards (there wasn't any mention of it in the product info), L-carnitine interferes with thyroid hormones. If you have hyperthyroidism, you can take it, but if hypothyroidism or hormone replacement for other reasons, don't take it. Also, the pills are pretty big and thus hard to swallow without food. It's difficult to rate since I only took it a couple of times before realising I shouldn't take it.
