A new study presented at the World Congress on Osteoporosis in Florence, Italy shows that DMPA, an injectable contraceptive commonly used, is associated with a higher risk when used alone, and not in combination with estrogen.All this sounds good except for one thing: The supplement industry billions of dollars has little regulatory oversight. The lack of supervision of the ingredients used to manufacture supplements don t have to be listed on the label s. This means that there are no guidelines t standard quality control or inspection of products. And this means that some consumers may be hazardous to their health while you’re thinking of improving it.
The study, conducted by researchers at the University Hospital of Basel, Switzerland and Boston University Medical Center, Lexington, USA, used a case-control study to evaluate the relationship between long-term use of DMPA, with or without estrogen, and the risk of fractures. The results show that in women under 50 years, long-term use of DMPA and more than two years is associated with a higher 50 percent risk of fracture.
