Vitamin D and Depression.
May 24, 2014 Admin 0
Vitamin D deficiency is now recognized by many as a pandemic. The fundamental cause of vitamin D deficiencies in the modern world are reduced sun exposure, even in warm climates, few foods naturally containing appreciable levels of vitamin D and poor eating habits in general. Those who are at the most risk from a vitamin D deficiency, besides those who consume poor diets, include those furthest away from the equator, those with medical conditions (such as liver disease), young children and the elderly.
One study, conducted in the Netherlands found that low levels of vitamin D had a direct correlation with symptoms of depression in almost 170 individuals over the age of 60. A somewhat larger study by an English University which involved well over 2000 subjects, all over 65, conclusively found that vitamin D deficiency is directly associated with depression in Northern European countries. They did note though, that severe depression only manifested itself in individuals with considerable vitamin D deficiencies.
Studies have administered high doses of vitamin D to subjects and witnessed strong positive effects on depression in as little as two months. Although depression is just one condition which vitamin D may help treat or prevent, it is very fortunate to have research showing how it can be so important in just one area. You do not even have to search very far to find that low Vitamin D intakes are associated with increased risk of cancer, hypertension, autoimmune conditions and infectious diseases.
At a minimum, circulating levels of 25-hydroxyvitamin D of >75 nmol/L, or 30 ng/mL, are something of a basic requirement for health. A diet rich in foods that contain vitamin D is not likely to be sufficient enough to provide even these levels and the absence of regular exposure to the sun, at least 1000iu of a vitamin D3 supplement, daily, is an excellent idea.
