                                While millions of people have a vitamin D deficiency, using high-dose supplements like the prescription product D-cure can be dangerous for certain individuals. This potent form of vitamin D3, or cholecalciferol, is not suitable for everyone and requires careful medical supervision to prevent serious adverse effects, most notably dangerously high calcium levels.
