Lighter Skin and Vitamin D

The lighter your skin the less sunlight you need to get adequate levels of Vitamin D-3, although everyone is still deficient from what I have seen without supplementation. 
If you have dark skin or tan easily then are going to be at a high risk of depression and SAD (Seasonal Affective Disorder). And not only in the winter, but year round!
For supplementation if you have light skin you might only require 2,000 to 5,000 IU per day to reach levels between 50-90 ng/ml but if you have dark skin you might need 5,000 to 10,000. The only way to know for sure is to test, however I have never seen a normal vitamin D-3 level without supplementation or regular tanning.
