Please be careful with pulling coconut oil if you are hyperthyroid or if you have any thyroid problem at all. I recently become severaly hyperthyroid after pulling coconut oil 20 minutes a day for six weeks. I was hypothyroid before but it was under control. Blood work done last week shows I am now severely hyperthyroid and the doctor is recommending that I either have my thyroid destroyed with radioactive Iodine or have it surgically removed. Even if you do not have a thyroid problem, I would suggest that after a month of coconut oil pulling you have your have thyroid bloodwork done and repeat that every three months. Stop the coconut oil if you start sweating a lot or have rapid weight loss that cannot be explained.
