Vit D is a hormone after all, and what level of supplement it takes to get you up to optimum levels varies as it would for thyroid or insulin or any other hormone. It isn't really good to think of it like Vit C with a more constant daily allowance.

Wow, that's crazy, considering where you live!
Do you wear a lot of sunscreen or avoid the sun? I'm just curious.
And why did grassroots.org test it? Isn't that a nonprofit support organization?
