Fortunately, I injured my heel. Fortunately, the pain persisted. I finally saw my doctor who ordered a blood draw. The diagnosis was plantar fasciitis. I learned to deal with my foot, but I came home with something much more valuable: the blood draw revealed I was deficient in vitamin D. That was September 2011 and I was 51 years old. It was time to get serious. I began taking over-the-counter vitamin D tablets, 2,000 international units (IU) per day, for several months. I also began researching.Vitamin D isn’t, in fact, a vitamin at all.(1) It is a hormone that helps regulate calcium in the blood. In its active form, vitamin D affects much more than bone health because of its significant repair and maintenance capabilities. As we age it becomes more difficult to make vitamin D in the skin, and with a deficiency, less calcium is absorbed. This increases the risk for osteoporosis and fractures. Elderly adults deficient in vitamin D score lower on cognitive performance tests. Just as unnerving, 17 varieties of cancer, heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, muscle weakness, muscle wasting, birth defects, periodontal disease, and Parkinson’s disease are associated with vitamin D deficiency. (2)Prior to 2010, the daily vitamin D recommendation was set at levels to prevent rickets. This has since been revised by the Institute of Medicine (IOM) and changed from 400 IU to 600 IU for adults. The current consensus is that this is not enough. (3)I was shocked my levels dropped after 10 months of taking supplements. Instead of 20.5 nanograms per milliliter—optimal levels are between 30 and 100—it was worse at 15.2. At this point I was fairly puzzled since I don’t avoid the sun and I’d been taking 2,000 IU tablets daily, but something wasn’t working. That was July 2012, and it was time to get more serious. Since some people deficient in vitamin D respond best to high doses in gel form, my doctor recommended 50,000 IU gel caps weekly for 12 weeks. I decided to check again in October 2012 and to keep researching. One theme kept surfacing: older adults are at significant risk for vitamin D deficiency. Something else caught my eye: 100 percent of elderly women admitted to the hospital for osteoporosis-related fractures were vitamin D deficient, yet half were already taking vitamin D supplements. Clearly, we are not getting enough. Stay tuned for the next blog post about vitamin D: Who is at risk and how do we get more vitamin D? How do we know what is in the supplements we take? What happened to my levels after taking 50,000 IU weekly for 12 weeks?
