Vitamin d: Depends on what your level is (requires lab testing). If you are deficient your dose will be different than of you aren't. I resend lab testing and complete physical by your primary physician.

Vit D level?: To answer this question correctly it's important to know if you are vit d deficient or not. That can be determined by the blood test.
