Taking Vitamin D Won't Protect Your Bones
Taking vitamin D supplements to protect your bones isn't necessary if you are a healthy adult, according to a new study. The research shows that taking supplemental vitamin D3 did not reduce the risk of hip, wrist or pelvic fractures. However, the study's results would not apply to people with a severe vitamin D deficiency, low bone mass, or osteoporosis. The study also doesn't apply to those in nursing homes because of the unique factors of their living environments. "They may not get out to get sunlight exposure to their skin or have good nutrition, both major sources of activation of vitamin D," Dr. Meryl LeBoff, professor of medicine at Harvard Medical School. Vitamin D is needed by the body to fully absorb calcium from the intestines. The vitamin also plays a role in immune health, brain cell activity and how muscles function.
