Lately, much has been written about vitamin D deficiency.  There are two forms of the vitamin, D3 and D2.  Which form of vitamin D is more effective for raising blood levels of the vitamin in our bodies?

A recent study by Dr. Robert Heaney of Creighton University, compared whether D3 or D2 was more potent and effective at raising blood levels of the vitamin.  One group of people in the study took  a D3 supplement, while the other group received a D2 supplement.  After 12 weeks of supplementation, the researchers tested the blood levels of vitamin D in each group.  The people receiving D3 had 56% to 87% higher levels of vitamin D in their blood, as compared to the D2 group.  In other words, the D3 form of the vitamin is more potent than the D2 form in correcting vitamin D deficiency.  However, the researchers noted that a longer study would be necessary to generalize findings to a larger population.

The bottom line from this series is:

• Consult with your doctor about possible vitamin D deficiency.
• If deficiency is present, taking a vitamin D3 supplement will be great for your health.

I hope you live well.

Do you live in the northern United States or Canada?  Are you over 60 years of age?  Are you African-American or have darker skin?  Do you rarely spend time outdoors?  Well, if you share any of these characteristics, you have a greater possibility of being deficient in Vitamin D.

A  deficiency of this vitamin could affect your health in a number of ways.  Currently, research is looking at possible links between vitamin D deficiency and increased risk of diabetes, muscle weakness, some common cancers, and dementia.

How can you reduce your risk of these potentially debilitating conditions?  Find out how in Part 3 of this series.  Live well.
