Classified as one of the fat-soluble vitamins, D has recently become the focus of many studies worldwide. Our body has mastered numerous ways of absorbing Vitamin D. We manufacture our own when skin is exposed to sunlight, and when we ingest certain plant and animal sources that become ergocalciferol “D2” or cholecalciferol “D3” respectively. Vitamin D’s complicated molecular structure is strikingly similar to steroidal hormones and plays a crucial role in stimulating growth and maintenance of the skeletal system. Besides its importance for bone health, D also supports immune function and healthy mood. Research has shown when blood contains adequate amounts of this vital nutrient (measured in nanograms “ngs” per ml) we get sweeping payback in overall health benefits. Blood levels in the range of 60-80 ngs/ml promote optimal immune system function which increases our ability to resist depression, cardiovascular disease, and virtually every inflammatory disease including cancer1. Even degenerative brain disorders have recently been linked to Vitamin D deficiency. I always suggest people ask their healthcare provider for a Vitamin D-25 Hydroxy blood test. Exciting research currently going on in Canada and some Scandinavian countries may affect the current recommended dosage of Vitamin D. Today average dosages vary anywhere from 1,000-10,000 international units or “IUs” per day, depending on the person’s blood levels.

Yes, Vitamin D is the forgotten necessity of life! Thanks for referring the website M. Hoffman. @ S. Holt Also, exposure to the broad spectrum of the sun's rays is crucial for absorbing it in the body. In Washington State we only receive a small percentage of the spectrum, and yes, ethnicity has a lot to do with the absorption as well. The darker your skin, the more melanin, and that requires supplementing a higher dosage of vitamin D if you can't get it from the sun. Last week I noticed Vitamin D was trending on Yahoo so I've put the website here for those who wish to research this more. Apparently, a lack of Vitamin D in the blood is the common denominator in almost every major disease/condition in humans from degenerative brain disorders to diabetes. http://search.yahoo.com/search?cs=bz&p=Vitamin+D+study%20&fr=fp-tts-375&fr2=ps

I understand that the optimum Vitamin D supplementation is largely impacted by individual and environmental factors, such as latitude where one lives, amount of direct exposure to sunlight, climate where one lives, ethnicity, etc.
