In 2013 sales of calcium supplements were $6 billion. In 2012, vitamin D supplement sales in the United States reached $748 million. For over a decade, these supplements have been proscribed to treat osteoporosis in older individuals. More recently however, studies have appeared that dispute the assumption that calcium and vitamin D supplements reduce the risk of osteoporosis after age 30.

New Method Increases Bone Density
Researchers from the University of Liverpool have found a new system which helps increase muscle contractions and eventually increases bone density.
This new method is extremely helpful in initial rat models and experiments. The results showed a 30% hike in bone growth, improving bone density. This new device is called a ‘miniature muscle pacemaker’ and is designed to produce contractions in the muscles. These miniature muscle pacemakers were designed by Professor Jonathan Jarvis of Liverpool John Moores University. In the rats, they were placed on the legs for a period of 28 days.
