what the evidence says
Same conditional evidence picture as all D3: reliable benefit when correcting low levels, little demonstrated benefit stacking more on top of adequate levels. 2000 IU daily is a widely used maintenance dose that keeps most adults in range; correcting an established deficiency usually takes more, which is why a test beats guessing in either direction.
Plain-language assessment of the human evidence. No cherry-picked citations.
