Other folks are much more careful about drawing conclusions. Margherita Cantorna, clinical microbiologist and immunologist at Pennsylvania State University, tells Inverse that human brain cells have vitamin D receptors, suggesting that vitamin D is critical. But there haven’t been adequate research in people to ascertain what just this means for psychological wellbeing, she says.
