Today's Topic in Focus: [02:48]
Vitamin D status is linked to a variety of health outcomes, and avoiding or correcting deficiency is important. However, does supplementing with vitamin D actually benefit most people? Is there evidence for supplementation improving health outcomes like mortality, cancer risk, depression or other outcomes? In this episode Danny and Alan look at intervention trials of vitamin D supplementation.
