Jan. 14 (UPI) – Taking vitamin D supplements has virtually no health benefits for people over the age of 70, says a new study.
A group of 70-year-olds took 300 micrograms, 600 micrograms or 1200 micrograms of vitamin D for one year and showed no change in bone mineral density or BMD according to a study published this month in The American Journal of Clinical Nutrition.
"Vitamin D deficiency is common in elderly people, and it can lead to bone loss, weakening of muscle function and increased risk of falls and fractures," says Terry Aspray, researcher at Newcastle University's Institute of Cellular Medicine and study author. , in a press release. "The results of previous studies evaluating the effect of vitamin D on bone mineral density have yielded conflicting results and our study is an important contribution to the current debate."
Loss of bone density among older adults may increase the likelihood of being injured during a fall. According to a recent National Security Council report, the third leading cause of preventable deaths in the United States is falling
In addition, nearly 30,000 Americans kill over 65 in 201
Danger of falling does not only endanger a person's life, researchers say, jumping into their self-esteem and confidence.  The vitamin D study, however, showed that 40 micrograms daily supplement helped bone metabolism.
To help bone strength, the study's researchers say older people should concentrate on eating healthier, getting enough sun and exercising regularly.
"The current guide is still that people with low vitamin D should consider taking a daily vitamin D supplement that everyone should have during the winter months," said aspray. "Work is needed to implement effective strategies to prevent falls and fractures among elderly people and understand the importance of medicine and dietary supplements therein."
