You recommend splitting the Armour thyroid pill and taking it twice a day. Can you explain why you feel this is particularly important?
A. Armour thyroid is a combination of T3 and T4. T3 products (like Cytomel) need to be taken twice a day to provide a steady concentration of thyroid hormone as it has a much shorter half-life than T4. Q. You describe something called secondary or tertiary hypothyroidism, where TSH is below 1.5 and Free T3 (and possibly the Free T4 as well) is below normal. How does this differ from primary hypothyroidism? Are there different causes for these different types of hypothyroidism? A. These are forms of hypothyroidism that are not directly due to the thyroid gland failing. Traditional viewpoints would classify this as pituitary or hypothalamus dysfunction. However, there are far more common reasons for this that tend to be primarily related to the adrenal gland. My experience has been that the bulk of individuals who have thyroid impairment with the new TSH criteria above 1.5, are in fact related to adrenal insufficiency. Other causes of thyroid dysfunction would be related to an impairment
