If you’re feeling the winter blues or Seasonal Affective Disorder, SAD, vitamin D supplements can often really help. It’s that time of year when those of us in the Northern Hemisphere are dealing with shorter days, lower light levels and cold weather.

SAD can leave you feeling tired, lacking in energy, moody, unable to concentrate – and sad! It could be a psychological disorder, or a hormone imbalance, but increasing your vitamin D intake might help. Even if you don’t have full-blown SAD, vitamin D levels might be low and can leave you feeling a bit down with the approach of winter.
