I purchased this product after it was referred to me for regrowing hair from a thyroid disorder. So far it's working and I don't have any side effects. I don't have any foul burping or a bad taste in my mouth. My hair is growing back and I can see a regrowth of about an inch on top of my head. I'm very happy with it.
