Bests & Worsts Reviews from Amazon

I originally started using these because i read that they can help remineralize teeth. I was taking them 3 times a day and noticed my thyroid was no longer enlarged after about 2 months. I started giving them to my husband and kids and bought some for my sisters and parents. Then I started noticing the dark spots on my bottom teeth close to the gumline getting lighter and smaller. One was a really big spot and it has gone done drastically. Can not recommend these enough!
