When my rheumatologist originally proposed doing it, it was about brain fog and fatigue, and being able to improve it. He literally said to me I'm gonna blow your mind if you're willing to try this, and I have to say the results are dramatic I can't say for sure what I may have needed, but in general the process is meant for you to absorb and process the nutrients you need better than you ever could just by eating or taking supplements. I am on prednisone and I did ask the IV nurse if she thought this could help me get off of it she said yes I'm a little dubious on that one, but I can't deny the improvement in my energy level and mental clarity.
