Do you suffer from Seasonal Affective Disorder (SAD)? SAD is a type of depression that typically occurs during the dark winter months of the year.

Ten million Americans suffer from SAD every year. Having a family member with SAD, having a diagnosis of depression or bipolar disorder, or living far from the equator can all put you at greater risk of this condition. Unfortunately, more women than men are diagnosed with SAD.  Thankfully, there may be some nutrition tools that can help alleviate some of the symptoms.
