Taking a DHEA supplement combined with vitamin D and calcium can significantly improve spinal bone density in older women, according to a new study from a Saint Louis University scientist and his colleagues at Washington University.

According to the National Osteoporosis Foundation, osteoporosis affects more than 2 million men in the United States and nearly 12 million more have osteopenia—clinically significant low bone density that is less severe than osteoporosis.

Patients treated with intravenous bisphosphonates are at an increased risk of jaw or facial bone deterioration or infection, according to a study published online June 26 in the Journal of the National Cancer Institute.

Two new studies suggest older men and women taking selective serotonin reuptake inhibitors, a class of antidepressants that includes Prozac, Paxil and Zoloft, are prone to increased bone loss.

Researchers at the University at Buffalo have described a novel pathway by which estradiol, the primary estrogen in humans, aids in maintaining bone density, a function critical to avoiding osteoporosis.
