I have a couple friends who suffered from hypothyroidism for years. It is critical to provide your body with the nutrients to support the thyroid gland! Some top nutrients include L-tyrosine, selenium, manganese and iosol iodine (a unique water soluble form of iodine). These nutrients can help with the formation of T4 and the conversion to T3 in the body, naturally. I know Wellness Resources offers some great thyroid support.
