- TSH- level should be between .3 and 3.0
- Free T4-storage thyroid hormone (the "cake mix"--needs to be activated or baked ie turned into T3) level should be ABOVE the 50% of normal (if range is 1-10 level should be 5)
- Free T3- actual thyroid hormone that can be used by body. Level should be ABOVE 75% of normal range (if normal is 1-10 then you should be 7.5 or above)
- Thyroid Antibodies - proteins that attack the thyroid gland
- Reverse T3 - measuring sidelined T3 that is unavailable to body
- Ferritin - stored form of iron (normal range is 20-100 but optimal is 60 or 80 if you need to lose weight)
- Vitamin D - normal range is 20-100 but want to see 60 0r 80 for women who want to lose weight. Get blood level to determine supplementation for this critical hormone. Some doctors suggest 5,000 a day for people whose blood levels are low. There is a once a week prescription of 50,000 IU for people who levels don't respond to daily supplementation. Ask your doctor about this. Watch CBS News Watch about the importance of vitamin D.
