Re: might want to read this Don...

John,
from the research paper you have posted on.............

"The researchers speculate that the reason may be the dose of vitamin D used in the study. It's the largest total annual dose of vitamin D -- 500,000 international units"

No serious researcher into Vitamin D would advocate one annual dose of 500,000ius.
This totally invalidates thus flawed study.

I think it was DQ who said may be we should all take our annual supply of water in one dose and see what would happen.........death to be sure.

This only proves the safety-factor involved with such a large dose given at one time of Vitamin D as a nutrient, and in comparison to pharmaceuticals, absolutely safe.
