How vitamin D works biologically

Few nutrients get as much hype as vitamin D. It’s been promoted for everything from stronger bones and better mood to reduced risk of chronic disease and cancer prevention. And during the COVID-19 pandemic, a wave of self-proclaimed “vitamin D truthers” took things further—claiming massive doses could prevent or even cure the virus. But what does the science actually say about how much Vitamin D you should be taking? And are there truly health benefits of mega-dosing Vitamin D? Join us, two Registered Dietitians, as we dig into the ‘sunshine vitamin’ and shed light on the facts (and fiction) surrounding this much-debated nutrient.
