Hope your getting enough B vits and iron, that can be hard for vegans. I think extra iron may be required with Miracle-Mineral-Supplement too, but I haven't found enough info on this yet.
For the extra magnesium needed a good cheap and functional form is Concentrace minerals, a serving will provide 60% of RDA.
I am certain that fulvic acid is the missing link in our diet and helpful to all, especially the sick!
