Is too much Vitamin D bad?

[TitanWIP]

I saw this headline:

Report: A bit more vitamin D is good, not too much

The Associated Press: Report: A bit more vitamin D is good, not too much

Yes for average people living in a southern state/warm sunny climate.

BBers and people in Midwest need more.

Colder climates due to the sunlight rays that the body uses to make V-D are filtered out by the ozone due to the increased distance they has to travel.

Personally I sup over 10,000 IU's cycled with 4000. I would not recomend this for anyone else, 400 IU's the most out side your foods.
Reasons I do=
1. I live in Midwest
2. 98% of the time I'm inside.
These rays for V-D are filtered out by window glass just like with the ozone.
3. I don't get much in my foods.

For studies like this they need to state parameters they use. To many variables.
