I supplement 2000 IU Vit D for years ans my blood level stays always at 40 ng/dl. Since I have asthma and allergies, I wonder if higher levels would make s difference. There smis not much data for changing levels from 40 to higher.

Anyone any experience or recommendation?

What level of D dies BJ have?
