I've given up on it. I'm deeply unimpressed by what mineral research I've looked at - it all seems like my original comment, that they are useful chronically during development, but not acutely after you're a grown adult (except in rare cases of major deficiency like iron deficiency for pica or anemia, which is equally useless).
Right, the evidence of supplementation isn't great, but I have plenty of cites for dietary mineral intake reducing all or specific cause mortality compared to mineral deficient diets, in adults.
As of now my hypothesis is that mineral supplementation is probably good in the case of deficiencies, but still not nearly as good as optimizing diet to fix deficiency, because the human body is a sublimely complex system and that there are many important functional nutrition ratios important beyond the widely accepted ones such as Zinc/Copper, Sodium/Potassium, etc...
