"Association of Serum 25-Hydroxyvitamin D3 and D2 With Academic Performance in Childhood: Findings From a Prospective Birth Cohort"
While vitamin D has been shown to boost adult cognition, students' school performance doesn't benefit from an extra dose of sun or a vitamin supplement, according to a study at the University of Bristol, in England.
Researchers analyzed the levels of vitamin D and calcium in blood samples taken from 3,171 students in the Avon Longitudinal Study of Parents and Children when the children were about 10, 12, and 15 years old, and compared them with the students' academic performance on national tests taken at around the same ages. They found no link between high levels of vitamin D or calcium and students' test scores.
