Hi, shevroletti. Hope you've had a chance to look around. My son has opted for the present to forego the standard treatment of DMD's and instead treat with what would best be called an enhanced-natural approach. By this I mean diet and supplementation. The diet is a Dr. Terry Wahls/ketogenic hybrid, and supplements include B-complex, calcium/magnesium/zinc, vitamin D3 (which I just learned today on this site might be better served with a calcitriol/D3 mix than D3 alone), alpha-lipoic acid, inosine, resveratrol, N-acetylcysteine, and LDN (low dose naltrexone). All of the supplements, with the exception of LDN, are either naturally derived or synthetic-yet-chemically-identical to natural, at least to the best of my knowledge. That being the case, I can't offer any help concerning your experiences with DMD's, but there are a lot of members on this site who can. If you have a specific question, about Tysabri perhaps, go to that thread and post. Good luck!
