My MGUS has been known since 2015 so it's been around a while.
I had not been told by my GP that he was arranging an appointment with an oncologist/haemotologist so you will imagine it was a bit of a rude shock when the appointment turned up in the mail.

Like you, I was really concerned after MGUS was confirmed and tried everything for a lengthy period but my condition remained stable. I started removing supplements one by one until I learned that Turmeric was the only thing making the difference so I added powdered (sunflower) lecithin to improve the bio-availability of the turmeric powder and have remained stable since. Everyone is different. So what is good for me might not be for you. Consult with your medical team and take good care of yourself too. You need both. I also exercise a lot and that is probably one of the keys. Good luck and health for your future.
