Vitamin D and cardiometabolic risk: what supplementation can and cannot do

Vitamin D is important, but it is often overpromised as a cure-all. The real value comes from correcting true deficiency and avoiding excess. This guide reviews 25-OH targets, dosing boundaries, and how vitamin D fits into cardiometabolic strategy.[5]

Vitamin D correction is most useful when deficiency is documented.

Safe dosing requires boundary awareness and retesting.

Cardiometabolic improvement still depends on multi-lever intervention.
