I hope you don’t end up giving yourself a kidney stone with all that vitamin D.
I don’t take Vitamin D except in my multi vitamins.
The important vitamins are B6,C and E in high doses. That pretty much eliminates heart attacks and cancer. Now you do need lots of water and Sea Salt to absorb the water and that it takes it easy on your kidneys.
At any rate, I learned a lot about health and really do not fear anything anymore.
