| Re: Does Vitamin D deficiency cause any mental problems?
Septerra,
I have read that Seasonal Affective Disorder (SAD) is a result of lower levels of Vitamin D in the winter. I used to be depressed every winter even in sunny central California. Then we moved to northern Germany 12 years ago. Not only are we further north than we were in California, but the weather here is mostly depressively oppressively grey. Overcast and grey. Rainy and grey. Did I mention grey? Grey.
I started going into depression earlier and earlier every year. One year I didn't come out of it until August, and I had been contemplating suicide. Then I read about Vitamin D. I started taking 1500 I.E. of Vitamin D3 (Colecalciferol) per day, all year. I have not had SAD since. This winter is particularly grey, and I've upped my dosage to 2000 I.E. per day.
