what the evidence says
Vitamin D supplementation clearly helps the deficient, with good evidence for bone, muscle function and likely respiratory immunity, and does little for the already-replete; low levels are common in indoor-living Singapore despite the latitude. Fatigue specifically improves in deficient people in several trials. Test, then dose.
