Seasonal Affective Disorder (SAD): SAD is a form of depression that occurs in the fall and winter months, probably in response to the fewer hours of daylight.
"Dr. Weil recommends that everyone take a daily supplement of 2,000 IU but notes that higher doses of vitamin D may be needed to effectively treat SAD."
"Sara Hayden, a mental health therapist at TFP Therapeutic Services in Ontario, Canada, recommends . . . vitamin D-boosting strategies to address the wintertime blues"
"Exposure to sunlight is a significant factor in seasonal affective disorder. . . . What’s more, lack of sunlight is linked with lower vitamin D levels, which in turn has been correlated with depression and low energy."
“A 2014 study published in the journal Nutrients found that people who took vitamin D supplements saw significant improvement in their depression.”
"It's amazing that something so simple could make such a difference. The patches work great!!"
