Some of the best results have been obtained in studies using considerably higher than the typical 400 IU doses daily and administering calcium simultaneously. Response also appears sensitive to the subject population. More geriatric and infirm populations that are indoors more, tend to have lower vitamin D levels and these populations seem to show greater response to vitamin D therapy.
In a three-year study, supplemental vitamin D was given at a dose of 800 IUs daily in combination with a calcium supplement. The population group included nursing home residents who were indoors most of the time. The vitamin D-calcium combination was found to significantly protect against hip fracture in this randomized, double-blind, placebo-controlled study.
In another recent three-year double-blind, placebo-controlled study, a combination of vitamin D (700 IU`s daily) and calcium (500 milligrams daily) was tested for its effects on non vertebral fracture incidence and bone mass maintenance in 389 men and women older than 65. The researchers concluded that this combination "led to a positive change in biochemical markers related to bone turnover, slowed the rate of bone loss and significantly decreased fracture incidence."
