Vitamin D & its’ AFFECTS on Seasonal Affective Disorder (SAD)

December 21, 2009

Can lack of vitamin D can contribute to seasonal affective disorder (sad)?

Less sun light during winter months can dampen your mood and affect the vitamin D levels in your body. So one may think there is a link between the “sunshine” vitamin and seasonal affective disorder (SAD). Scientfic studies have addressed the issue, but the results have all been inconclusive. In 1993 study performed in Boston found no benefit for vitamin D supplements over a placebo. Yet a small study performed in 1999 on patients with seasonal affective disorder, found that large doses of vitamin D were more effective than the standard light therapy. Other multiple studies have also linked low vitamin D levels to mood disorders in the elderly.

Scientists have found that specialized cells in the retina respond to long-term light exposure and communicate directly with the brain, this may be the reason light affects our mood. Vitamin D is produced in the skin in response to ultraviolet radiation from the sun. Light boxes used in studies related to treatment of seasonal affective disorder do not produce the same UV rays as the sun. Patients must sit under a light for 45 minutes a day in order to consume the daily amunt of vitamin d needed. It is much more convenient to take a pill, but scientist also recommend getting outdoors during the winter as often as possible.

People should not underestimate the potential of vitamin D supplements. Studies have linked the vitamin to prevention of colon and breast cancers, osteoporosis, heart disease, and multiple sclerosis, taking 1000 or 2000 IU per day as a supplement could benefit your health on many levels.

Women with low levels of Vitamin D in are more likely to die from heart disease and cancer, than women with higher levels (above 27 ng/ml), according to findings published by Nutrition Research.

In addition, a recent meta-analysis suggested that Vitamin D Supplementation was associated with decreased mortality. The researchers explained a causal relationship between Vitamin D deficiency and mortality, Vitamin D is used in range of effects including control of inflammatory compounds, immune health, regulating blood pressure and reducing arterial hardening. Vitamin D’s uses vary between the different types of tissues in your body. This may be the link between vitamin D deficiency and cardiovascular disease, cancer, and mortality.

*During 6 years of follow-up, 100 of the 714 women died with data showing that the main causes of death included cardiovascular disease (36 per cent), respiratory disease (18%), cancer (15%), and other causes (27%), state the researchers. Read more…
