When I have inflammation issues, i.e. back pain, shoulder, etc., I routinely apply Mg oil (magnesium chloride) then apply DMSO. Had read years ago that the DMSO helped the Mg oil to be absorbed, like it does for most anything else. Wondering if there is much of a difference between the chloride form and the pidolinate form? One is certainly more expensive than the other. I guess I will test it out, but I will have to notice a significant difference in order to convert over due to price point. Also, this question I am sure has already been answered, but is the DMSO pharma grade (I'm sure it probably is)?
