Are vitamin D levels linked to mental health?

Low levels of vitamin D may be associated with an increased risk of depression in mid-life, says a new study from University College London in the UK.

The study, which indicates correlation and not causation, found that people with vitamin D levels of at least 75 nmol/l had a 43% lower risk of depression, compared to people with vitamin D levels lower than 25 nmol/l.

Results published in Clinical Nutrition also indicated that the higher vitamin D levels were associated with a 67% lower risk of panic, compared to the lower levels.

“The high burden of mental and behavioral disorders and concurrent high prevalence of vitamin D insufficiency (<75nmol/l) worldwide (29) highlight the potential importance of our findings,” wrote the researchers, led by Jane Maddock from the UCL Institute of Child Health.
