Vitamin D deficiency in America is a growing problem for both adults and children. As more and more Americans regularly use sunscreen and spend more time indoors, levels of Vitamin D are decreasing at an alarming rate. Some medical experts even claim we are suffering through a Vitamin D deficiency “crisis.”
In fact, 70 percent of whites and 97 percent of blacks in the United States have insufficient blood levels of Vitamin D, according to a study conducted by researchers at Harvard University and the University of Colorado, and published in the Archives of Internal Medicine.
The study also found that the proportion of people with adequate Vitamin D blood levels had dropped 50 percent since the time period between 1988 and 1994. They attributed this effect to people spending more time indoors than ever before, and going out only when protected by high-SPF sunscreen.
Scientists have known for a long time that insufficient levels of Vitamin D can lead to Rickets in children and can increase the risk of fractures and Osteoporosis in adults. More recent research has strongly suggested, however, that even levels that are adequate for bone health may still be too low to protect against heart disease, cancer and autoimmune disorders.
Current RDA Guidelines for Vitamin D are Outdated in Light of New Research
Scientific evidence continues to emerge reaffirming that current recommended daily allowances (RDA) of Vitamin D are insufficient for young and old alike. The daily recommended dosage (RDA) of Vitamin D is set at 400 IU (international units). This level of Vitamin D is considered by many experts to be the absolute minimum the body needs in order to avoid health problems.
In an editorial in the March 2007 edition of the American Journal of Clinical Nutrition, a prominent group of researchers wrote, “The balance of the evidence leads to the conclusion that the public health is best served by a recommendation of higher daily intakes of Vitamin D. ”
A lecture in Houston presented by Dr. Abbas Qutab in September, 2007 stated, “The overall general recommendation for Vitamin D supplementation should be 4000 IU/day.”
How much is enough?
Several studies have shown, depending on your age, diet and where you live, 2000 – 4000 IU of Vitamin D are necessary. Additionally, for some, up to 10,000 IU may be needed to restore their bodies to acceptable levels. This may seem like a lot, however consider the fact that your body naturally produces about 10,000 IU of Vitamin D-3 during 30 minutes of moderate exposure to the sun.
