It has T1 and T2 as well as T3 and T4. It's the closer to our natural thyroid than synthetic. We feel better, hour hair and nails are healthier, brain fog goes away and we aren't as tired or cold.
On synthetic I felt better than nothing, but still felt like crap! Doctors said I was just getting old. I fought to get on natural thyroid over 20 years ago and feel so much better. My numbers no longer fluctuate.
My doctor takes it and my husband's doctor prescribes natural to his family.
I am an advocate for natural Thyroid and have only gotten positive feedback from everyone who has switched.
I go to Dr. Desai.
You can google it yourself. Here is a quick link.
