Numerous studies have documented epidemic levels of vitamin D deficiency in the population at large and in particular, the elderly suffer excessive rates of deficiency due, in part, to lower levels of sun exposure. Studies have documented increased rates of infections and pneumonia in elderly subjects with vitamin D deficiency. Another recent study took a look at physical performance related to vitamin D deficiency.
A recent journal article in the Journals of Gerontology reported vitamin D plays a critical role in musculoskeletal function. In this reported study, researchers found an association between vitamin D status and physical performance in a sample of almost a thousand persons over the age of 65. Initial blood tests revealed nearly 3/4 of women and over half of men had vitamin D levels that were considered insufficient. Subjects were analyzed using handgrip strength and a physical performance battery, including measures of walking speed, ability to stand from seated position and maintenance of balance. Among those subjects with low vitamin D levels, physical performance and grip strength were significantly lower than those without a deficiency. Researchers included consideration of other variables and results maintained validity.
Physical performance and ability to conduct activities of daily living along with getting adequate exercise are related to numerous other disease states such as diabetes, heart and vasculature disease, impotence, obesity along with all complications of obesity. These study results are stunning in their illustration of the apparent dependence on vitamin D for vitality.
Recommendations for daily supplemental vitamin D intake have increased in the last 2 years for elderly and our youngsters. For elderly, intake of at least 600 IU of vitamin D is currently the governmental standard. I personally recommend intakes of approximately 1200-2000 IU per day. Since vitamin D is a fat soluble vitamin, it is possible to take too much. Consult your physician for further information on supplemental intake of this critical nutrient.
