Hi. Today I was told by my doctor that I have hypothyroidism and he has given me a prescription for Levothyroxine (25mil). I've been told that I will be taking this medication for the rest of my life.
I wanted to find out more about this medication,
1. What it is derived from?
2. How is a synthetic hormone manufactured?
3. Is there scientific research available?
4. Are there any long term side effects?
5. Are there natural alternatives?
Excuse the naivety here, this is all new to me.
