Calcium, vitamin D and fracture
Doctors have long recommended taking calcium with vitamin D to help prevent osteoporosis, but evidence that these supplements may reduce fracture is inconsistent. In this analysis of eight studies conducted between 2011 and 2015, covering 30,970 men and women, researchers found those who took calcium and vitamin D supplements were 15 percent less likely to experience any kind of bone fracture compared to those who did not take calcium and vitamin D supplements. Doctors also found those who took calcium with vitamin D were 30 percent less likely to have a hip fracture compared to men and women who didn’t take calcium and vitamin D.
Doctors said the findings support using calcium and vitamin D supplements to reduce chances of fracture in both independently living middle-aged and older people, and those living in caregiving institutions.
Vitamin E may protect BMD in women
Doctors in this study measured the diets of 3,203 adult men and women and compared whole-body bone mineral density (BMD), and BMD of the lumbar spine, hip, leg, and thigh. While there was no benefit in men, women with the highest circulating vitamin E levels had the greatest BMD in these areas.
Discussing the findings, doctors said oxidative stress may play a role in osteoporosis, and that postmenopausal women with lower estrogen levels often have more oxidative stress. The antioxidant properties in vitamin E may provide its bone density benefit, by helping balance the flow of calcium into and out of bones.
