Maryo Shomon reviews more research from the 2004 European Thyroid Association Annual Meeting. She heads up the top thyroid site on the net and has written a great book on the topic.
Synthroid is exclusively T4 while Armour is primarily thought of as T3 and T4 but it also has T1 and T2. Now a new study looked at the effects of another T2 to determine if it could raise metabolism and burn fat without inducing throtoxicity. In the study compared to untreated high-fat fed animals, T2 treatment resulted in a reduction of:
- Body weight gain,
- Fat accumulation,
- Serum cholesterol and
- Tryglicerides
Heart rate, T4, T3 and TSH levels were unchanged, indicating that the T2 did not induce thyrotoxicosis. The researchers concluded that " If these results hold true for humans, pharmacological administration of T2 might help to counteract pathologies linked to hyperlipidemic states without inducing a thyrotoxic state. Further documentation that Armour is superior to Synthroid or other forms of T4 (levothyroxine). I also posted an article in NEJM five years that suggests the same conclusion.
