While living in Sweden in 1998 I was fascinated to learn about how doctors there treat clinical depression. Prozac was forbidden. You cannot prescribe it in Sweden. But what they did prescribe, and pay for, was a sunny vacation for 2 weeks to the Greek Isles. I could not believe it. But it was true. The Swedes understood the power of the sun to lift people out of their doom and gloom, and put a smile not only on their face, but in their brain.
Now research shows the power of Vitamin D, the sunshine vitamin, to change how we feel.
Dr. Mercola reports "
The connection between vitamin D and depression is not new. In 2006, scientists evaluated the effects of vitamin D on the mental health of 80 elderly patients and found those with the lowest levels of vitamin D were 11 times more prone to be depressed than those who received healthy doses.
In the current study, researchers found that intake of more than 400 IU of vitamin D from food sources was associated with a 20 percent lower risk of depressive symptoms compared with intake of less than 100 IU. This was a significant benefit from a very small amount of vitamin D -- as 400 IU is far too low to benefit most people (not to mention your body is made to get vitamin D primarily from the sun, not food or supplements, as I'll explain below).
It now appears as though most adults need about 8,000 IU's of vitamin D a day in order to get their serum levels above 40 ng/ml, which is the lowest they should be. Ideally your serum levels should be between 50-70 ng/ml, and up to 100 ng/ml to treat cancer and heart disease."
With these findings, if you live in North America, you might think about getting your blood tested for the Vitamin D levels and taking action if they are low. Your entire mood might change!
