Very potent but caused me and my wife a headache

Posted by 4690282066383692459 on Jun 14, 2017 | Verified Purchase

It's a little too potent and I felt a bit strange with headaches. Maybe it's suitable only to people with problem with the thyroid. It's better to start with small and diluted doses, something like 15-20Mcg and see how you feel.

Way too much for me

Posted by Reviewer1310601 on Apr 29, 2017 | Verified Purchase

Even one drop is too much for me, just cannot take this formula. This was a waste of money for me. I have to take tablets that are not as strong. If you just starting out, I would recommend something different.

AMAZING PRODUCT! Stopped itching head and involuntary feet movement.

Posted by 5003802474041503826 on Feb 23, 2017 | Verified Purchase

Originally I purchased this product after investigation on why my eyebrows may not be growing and realizing it could be a lack of iodine. BUT after taking the product a very curious thing occurred which I had not expected which was unrelated to my eye brows. For many years my head constantly itched, it became part of my life style which became a norm. Also when I would be setting with my feet propped up, when I talked my feet would involuntarily move. This is also a problem of many years. After taking this particular product for two days my eyebrows still have not grown BUT itching head and involuntary feet movement have disappeared. My feet do not move when I talk and my head has stopped itching. Such an amazing product. In fact, a product which is among my daily intake. After researching I found that most people have a lack of iodine. I am so thankful for this product.

Arrive bottle broken refused delivery

Posted by Reviewer1367342 on Nov 30, 2016 | Verified Purchase

Ship your items and mark the outside as fragile and securely pack the inside. I am tired of revceiving broken glass bottles and having to refuse delivery. Shame on you. What are you in pre school?
