So I have this potassium sulfate powder that is used as a plant fertilizer, and my retailer says it is "food grade".
Can I take tiny doses (like 1/4 of a teaspoon) as a potassium source for the body? RDA says we should take 4,700mg of potassium everyday (more if you are phisically active or lift weights), but for an extremely unknown reason supplements are limited to 99mg, WTF is this some kind of conspiracy or what? Also, sulfur is apparently the 3rd mineral inside our body and many of us are defficient on that.
I already get some sea salt everyday, it tastes good and feels great. Can I combine both? Or is potassium sulfate toxic in any way? Thanks in advance.
