As with all prescribed treatments, please speak with your doctor or research on dosages if going homeopathic. You can overdose and die if you treat the thyroid too much. As a person who has hypothyroidism I have done both prescription and natural and tested after a 2 month period. I took Kelp (pill form), and I’ve even done liquid iodine, for the months, and various prescriptions for various months. All worked amazing and all treated my hypothyroidism pretty much the same. I found Kelp the closest to prescriptopn strength treatments. I used ground kelp capsules. Just remember, if you go to naturally work on your thyroid, MONITOR YOUR DOSEAGE.
