Update on Vitamin D and Calcium Supplements for Reducing Fracture Risk
A review of most observational studies in “free range” healthy elderly without osteoporosis or increased fracture risks did not demonstrate any benefit from Calcium and Vitamin D supplementation in preventing fractures.
It appears from this randomised prospective trial, rendering the elderly population replete with Vitamin D DID NOT reduce fall propensity nor reduce non-vertebral fracture rates.
Another good idea bites the dust.
24,25-dihydroxyvitamin D is an inactive metabolite of 25-hydroxyvitamin D (D3), destined for excretion. What the body needs will be converted from D3 to active 1,25-dihydroxyvitamin D. The higher the ratio of 24,25-dihydroxyvitamin D to D3, therefore, reflects the adequacy of Vitamin D for calcium homeostasis and bone growth. Understandably, a higher ratio correlated better with bone mass density and a lower hip fracture risk in this study.
