How do our bodies convert sunlight into actual vitamins?

Question

Is this an exaggeration or can I really become ‘healthier’ by standing outside in the sun??

Your body doesn’t “convert sunlight into vitamins” just generally. It specifically only works for vitamin D. Specifically, the ultraviolet light from the sun interacts with a protein in you skin and that interaction turns the protein into vitamin D.
