Our best source of vitamin D has always been sunshine; however, the use of sunscreen can limit the amount of vitamin D actually absorbed from the sun.  Cloudy, rainy climates also add limitations.  Cod liver oil can also be a good source, though you have to read the label to be sure.  All cod liver oils are not the same. 

Individuals who do not get sufficient sun exposure and do not take cod liver oil have to resort to fortified foods for their vitamin D intake.  Cereals and dairy products are fortified adequately, but individuals on a GF/CF diet will miss out on much of that fortification.  Check your food labels to determine whether they contain vitamin D. 

Recent research is now suggesting that many children and adults are not getting enough vitamin D for maintaining good health.  This research is suggesting that many other health conditions in addition to healthy bones and teeth may be very vitamin D dependent.  Kirkman® recommends looking up this recent research on the Internet so you can determine if you and your family may need to supplement with additional vitamin D.

Kirkman offers hypoallergenic Vitamin D-3 (cholecalciferol) capsules in 400 International Units (IU) or 1000 IU potencies.  The 100% recommended daily value for this nutrient is 400 IU, though scientific evidence is mounting that many individuals need more than that.  

Check with your physician to determine if your family is getting adequate vitamin D supplementation.  A lab test is available to check your levels.
