Levels of vitamin D

Low serum levels of vitamin D are associated with clinically significant symptoms of depression in otherwise healthy individuals, new research shows.

Making a series of assessments of healthy women during a 1-month period, investigators found that more than one third of participants had depressive symptoms, that almost half had vitamin D insufficiency, and that depressive symptoms were predicted by vitamin D levels.

“Vitamin D deficiency and insufficiency occur at high rates in healthy young women, and lower vitamin D3 levels are related to clinically significant depressive symptoms,” say the researchers, led by David Kerr, PhD, School of Psychological Science, College of Liberal Arts, Oregon State University, Corvallis.

Noting that vitamin D supplementation is a low-cost, simple, and low-risk intervention, they add: “Given the lifespan health risks associated with insufficiency, supplementation is warranted whether or not the modest role of vitamin D in depression observed here generalizes more broadly.”
