Increasing magnesium intake could increase bone density in the elderly and reduce the risk of osteoporosis, suggests a large American study.
"Higher Mg intake through diet and supplements was positively associated with total-body [bone mineral density] BMD in older white men and women. For every 100 mg per day increase in Mg, there was an approximate 2 per cent increase in whole-body BMD," said Kathryn Ryder and colleagues.
Osteoporosis is characterized by low bone mass, which leads to an increase risk of fractures, especially the hips, spine and wrists. An estimated 10 million people suffer from osteoporosis in the US alone, while another 34m are believed to have low bone mass, which puts them at risk of developing the disease.
