I put up a comment about this here.

The information continues to come in about Vit D and its potential for improving health.

I find it interesting that very little negative information is coming forth as well.

So we can only read the studies, and be monitored by a doctor,
while trying high Vit D treatments.

There has just been a Vit D3 topical ointment approved in US for psoriasis. (in the previous years, only one patient developed hypercalcemia with topical D that I read about.)

The risk of hypercalcemia accompanies this new ointment.
Previously, Vit D ointments were not considered safe. But newer studies are showing different results.
It might be that eventually, all of us may be using this rather than oral capsules. I see this coming in 5 or more years, based on if there is a lack of toxicity with this new product.
