underactive thyroid
"Cytomel is making my brain work so much better again! I tried it several years ago and it made me me jittery, I felt like I had a huge amount of caffeine in me.... not this time! I'm in peri menopause and I understand the estrogen dominance can be a thyroid hormone antagonist, making it difficult to convert. Cytomel has helped me feel almost entirely back to normal and I have the energy to exercise again!"
