Have you had your vitamin D level tested lately?  If you have, did your blood level come back low?  Many individual's vitamin D levels are low as a result of increased use of sunblock, reduced time spent in the sun and decreased dietary intake.  If you suspect your vitamin D levels are low or your lab results show that it is in fact low, try incorporating these vitamin D-rich foods into your daily diet.  Always seek the advice of a health professional, such as a Registered Dietitian or Physician before taking vitamin D supplements.
