Low Vitamin D Related to Depression

Older men and women with lower levels of vitamin D in their blood are more prone to become depressed over time.

Vitamin D, produced by the body when skin is exposed to sunlight, is also found in certain foods such as oily fish. It helps cells absorb calcium and is important for bone health. Low vitamin D levels have been linked to heart disease, stroke, high blood pressure, and more severe asthma. In older people, insufficient vitamin D is quite common, and has been linked to fractures, worse physical function, greater frailty, and a wide variety of chronic illness. Many studies have been published on the potential health benefits of vitamin D and the potential risks of deficiency. To explore the relation between low vitamin D and depression in older people, researchers from America followed 531 women and 423 men, aged 65 years and older for over six years.
