Here's another suggestion that might help. There are certain nutrients the body needs in order to properly convert T4 to T3, such as zinc, copper, tyrosine (an amino acid), selenium, and manganese and iodine (which are necessary for the creation of T4).

You might consider taking a nutritional supplement like Thyroid Support that contains all these ingredients.

This would be a good supplement for anyone who has even a slightly under-active thyroid, including those of us who are mercury toxic.

In fact, a friend of mine was diagnosed with a hypothyroid condition and they put her on Levothroid for 2 months. She felt worse on the medication and when she went back, the doctor said her numbers were lower and they should increase the dosage to see what would happen. She said "no thanks."

Instead, she began taking Thyroid Support capsules. She said she can't believe how much better she feels now. Thyroid Support has made a huge difference for her and she tells everyone!

Hope this helps,
