Vitamin D can be created by the body when the skin is exposed to sunshine for a small amount of time.
Certain factors such as amount of melatonin, lack of sunshine and certain lifestyles can diminish Vitamin D stored within the body.
A lack of Vitamin D can cause lethargy, tiredness, muscle problems, bone pains and mood changes.
Certain health problems such as a weak immune system may be assisted by Vitamin D.
