Vitamin D Deficiency Affects Only 6% of US and Supplements Unnecessary, Study Says
Misinterpretations of blood tests for vitamin D often lead patients to wrongfully think they have vitamin D deficiency, leading them to take vitamin supplements unnecessarily, according to a recent study published in The New England Journal of Medicine. The perspective article, "Vitamin D Deficiency — Is There Really a Pandemic?," shows that, contrary to what some think, vitamin D deficiency is far from pandemic, with only six 6 percent of Americans ages 1 to 70 deficient for the vitamin. Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with skeletal deformities, but recent research is underscoring the importance of vitamin D in other health conditions, from cardiovascular disease and cognitive impairment to cancer, including prostate cancer. In fact, some studies suggest that vitamin D can regulate the immune system to prevent prostate cancer initiation and progression. Too much vitamin D, however, can also cause health problems. High levels of vitamin D increase the concentration of calcium in the blood, causing such conditions as nausea, constipation, abnormal heart rhythms, and kidney stones. Researchers at the Institute of Medicine of the National Academies in the U.S. set a recommended dietary allowance, or RDA, that established the daily requirements of vitamin D. By comparing vitamin D intake and blood levels with bone health, they estimated that infants up to 12 months need about 400 international units of vitamin D per day, those

    The war on supplements continues with more misleading publications filled with arbitrary standards used to advance an agenda. Vitamin D has two functions and is actually closer to a hormone that a vitamin. It is essential for calcium absorption but is also a major regulator of cell growth/death cycles. Early man woke up at dawn and went hunting for the day without sunscreen. He absorbed from the sun many thousands of milligrams of Vitamin D daily. Modern man sits in an office or factory and wears sunscreen when outside preventing vitamin D from sunshine. The number 600-800 offered here is hardly sufficient for calcium absorption. The following is only one of many studies on Vitamin D and cancer. . Vitamin D can correct cancer cells – “It can adjust almost everything in the cancer cell, switch genes on and off, reduce cancer cell division and it can calm the cells so they settle rather than spread. It seems vitamin D can return cancer cells to a normal and healthy state”. (Journal of Cell Biology, Nov 17, 2008: 183 (4): 697-710.) Each patient should err on the high side of Vitamin D3 and supplements are a good way to access this protection.

      Thank you for the thought provoking comment Lawrence. Please note that this is just one study and its findings. It is not definite in any conclusions.
