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.

After trying Jarrow Formulas brand of Carnitine, I wanted to try another brand, so I tried this one and I really couldn't tell much of a difference.
