No risk of hypercalcemia in patients taking extremely large doses of vitamin D - D blood levels of 118ng/ml and calcium levels at 9.6 (8.5 - 10.6 is normal) not sure of the units and don't care since it's in the same range.
oh and it was (mentioned in the DOI hotlink above) used to treat tuberculosis, rheumatoid arthritis, asthma - blood levels over 100ng/ml. I am unsure of what sort of evidence you need for ~100ng/ml being optimal. Preventing or curing covid? Preventing cancers? aiding treatment of cancer? Psychological and neurological health?
In fact, that paper explains why the limit was set to 50ng/ml, so maybe that will nudge you a bit ;-)
