Seriously, I am now advocating that patients get sun exposure - enough to get a mild sunburn - for three days prior to a surgical procedure. UVB sunscreens defeat the purpose (and the fun of running around naked outside).
I am now 75% convinced that supplemental (oral ingestion) of Vit D is good only for prevention of Rickets. All these other Vit D benefits are not being appreciated using oral ingested Vit D. Although there does not seem to be a "first pass" effect somehting is happening across the gut wall or in the kidney or liver such that Vitamin D3 (cholecalciferol) is not getting to where it needs to be.
