I don't remember who posted it or in what thread, but a while back somebody posted a link to a study that showed that MG patients who took D3 showed improved strength. I had some 2000 unit D3 tablets that I bought a while back and didn't take. I started taking them two or three weeks ago. I may be a little bit better. I am not one that placebo effect works very well with because I am so skeptical. It could be placebo, or maybe it has helped. Or maybe it has just been a good few days. Has anybody experienced this?
