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.
I used to take medication for hypothyroidism. Did a lot of research and thought I would try Kelp. After testing on myself, I found that 2 capsules once a week banished all signs of hypothyroidism: the extreme tiredness, the sluggish mind, depression. But you have to find your own dosage, dont overdo the kelp!
