I have been diagnosed with Hashimoto's thyroiditis for 6 years now and take Armour thyroid. Last year I saw a naturopathic holistic doctor to find relief from PMS symptoms and general fatigue and irritability, and acne. He prescribed me a natural progesterone cream to be used between days 14-28 of my cycle. It has made a huge difference in my energy levels, mood, skin clarity and elasticity, has even helped me lose some weight. I did not know this before, but it is common for women with hypothyroidism to also have a progesterone deficiency.

Here is another informative interview with a holistic doctor and author of The Miracle of Natural Hormones:

Doctors who treat patients for thyroid imbalances should be better informed about the roles that the other body's hormones such as estrogen, progesterone, DHEA, melatonin, etc. have in the body and their relation to thyroid hormone and thyroid gland performance, as well as the adrenal gland.
