Treatment with good bacteria widely used in probiotic supplements can strengthen bones, especially in females, finds a study that may develop novel ways of treating bone loss condition osteoporosis.
The study showed that healthy mice fed with Lactobacillyus rhamnosus GG (LGG) bugs demonstrated an immune response that stimulated an increase in bone density.
The effect seen in young female mice is linked to a metabolite called butyrate or butyric acid -- a type of fatty acid produced by gut bacteria. This in turn activated bone-enhancing immune cells, including regulatory T cells, the researchers said.
"The significance of the study is that probiotics are, at least in mice, an effective means to increase bone density," said Roberto Pacifici from the Emory University in the US.
"Our findings will need to be validated in human studies," Pacifici says. "If successful, this research could substantiate the use of butyrate or probiotics as a novel, safe, and inexpensive treatment for optimizing skeletal development in young people and to prevent osteoporosis in older people."
