Thanks for explaining. This makes me wonder if there is a problem in my gut. I was on a 50k IU / week dose because of low vitamin D. It made no impact. Being out in the sun, however, made a huge impact - so I get much more sunlight now and I'm fine. I wonder if the vitamin D issue correlates with largely indoor office work now vs farming of our ancestors and largely being outside.
