I’ve been using this oil for over a year. This is the only place I buy it. I started using this to see if it would help with my goiter on my neck and I just have to say FOR ME my golf sized goiter I HAD is now much smaller where you don’t see it protruding from my neck. My doctor was in shock. She told me to keep taking it and I will. I take 1 tsp. with organic apple juice daily.
