Sugar Daddy and other products are pretty much made out of it, so....
It has fulvic pre-added btw. Or, since it is listed as being magnesium carbonate, I presume you could just buy mag carbonate off ebay or somewhere, grind it super-fine, and add the fulvic for near enough the same product. I also know of magnesium oxide, but I doubt that would be considered organic. It's basically all magnesium though. Peace.To promote the precision required to build luxury levels of magnesium, i.e. elemental magnesium can be applied without unwanted sulphate or nitrate carriers.
