A couple of years of years ago, I was using 10000 iu a day of vitamin D and I was getting kidney pain very often. Nowadays I use 5000 iu on my skin, of which just 20% gets absorbed, so it's like I'm using 1000 iu orally. So far no kidney pain anymore.I was using up to 80 000 units. I know it is not much in Coimbra's world, but I was afraid to use more on my own.
I only tested vit D levels after 3 or 4 moths from stopping and it was 48. I did not test PTH.
