My Personal Experiences

All of My NDT Journey Milestones

My history with NDT medication (Natural Desiccated Thyroid) has been long and complicated at best!

  • I originally switched from NHS prescribed Levothyroxine to self-sourced NDT Thyroid-S (from Thailand) in late 2015.
  • In July 2019, I moved from self-sourced NDT to privately prescribed NDT (Armour Thyroid).
  • As of the end of 2020, I have been on a combination of Armour NDT and Levothyroxine (both privately prescribed). 

Self-sourcing any medication is risky. There is no way around that. You have to acknowledge that there are risks involved, especially if you don’t follow advice and protocols set by a medical professional for example, but NDT has saved my life when T4-only therapy simply did not work, and has done for many other thousands of thyroid patients. I cannot deny that.

Related: There was a large study conducted in 2020, showing NDT works just as well as synthetics.

NDT medication is available on prescription in the UK and is widely available in other countries such as the US. The problem we have is actually getting a doctor or endocrinologist to prescribe the medication in the first place, which can be hard. This very rarely happens on the NHS in the UK. Read about the complicated history here.

Because of this, I made the difficult decision to self-source my NDT originally as I could not afford to go private, but years later was able to finally get it via private prescription. All of the below links follow this journey.
