Your body uses Vitamin D all the time.
Your body can make Vitamin D in the sunlight, but ONLY if the sun is 60 degrees or more above the horizon, which is for all practical purposes, directly overhead.

Of you can, please point me at the websites that have documented cases of Vitamin D overdose.
Thanks!

That's what really sold me on supplementation. For most of the year there is little to no opportunity to make vitamin D from sunlight. And when the opportunity is there is when we most try to avoid direct sunlight.

That sounds like someone could only get half pregnant ..... Exposure is Exposure unless someone is referring to the Heat of the sun creating Vity D then i might buy the Quote of 60* above.

Actually Vit D along with a couple others are cumulative- however like anything else it should be taken sensibly and there is no problem. Mega-doses are the reason people can get into trouble.

The medical literature suggests most older people do not have/ get enough- a google check will bring up some reliable data.
