Hypercalciuria is one of the cause of kidney stone, how to prevent it on high doses of fit d3?
calcium stones are not directly correlated to vit d or calcium, i haven t checked all the studies on this but studies shown that vit d deficiency promotes more kidneys stones
the main reason of kidneys stones is probably vit k deficiency, if you want to prevent use vit k2 mk7 200-600mcg daily, i use 600mcg because i take a very high dose of d3
