A large cross-sectional study of adults suggests a link between low vitamin D levels and depressive symptoms.
The study, published in the November 2011 issue of Mayo Clinic Proceedings, involved 12,594 participants.
All participants completed baseline examinations that included measurement of serum vitamin D levels and an assessment using the Center for Epidemiologic Studies Depression Scale (CES-D).
According to the investigators, low vitamin D levels were common in the sample as a whole, with 50.7% of participants having levels in either the deficient or the insufficient range.
In the overall sample, higher vitamin D levels were associated with a decreased risk for current depression, based on CES-D scores.
This study was one of several that has looked at a connection between depression and Vitamin D. While other study results have been mixed, it is my opinion, that vitamin D supplementation is a safe preventative strategy when combined with blood testing.
