Does Vitamin K slow bone loss

High doses of vitamin KI map prove helpful to avoid fractures and cancer in postmenopausal women with osteopenia, but it doesn’t seem to prevent a decline in age-related bone mineral density, a new study suggests.

The study has been published in Journal of PLOS Medicine, weekly issue and it was the project of the University of Toronto. The researchers included 440 postmenopausal women with osteopenia that is a mild condition that occurs before osteoporisis. These women were given either 5 mg of vitamin KI or a placebo daily for two years.

The researchers found that lower back and hip measurements of bone mineral density at two and four years demonstrated the same reduction in the vitamin KI and the placebo groups as well. However, the researchers noted that in the women with vitamin KI over the four years of period, only few women had fractures and similarly cancer cases were also fewer in them.

According to the researchers, their findings are not definitive, as they didn’t focus on fractures or cancers in their study and secondly the study contained a small sampling group. The researchers suggested larger study to know the effect of vitamin KI on cancer and on fractures. They researchers assume those high-dose supplementations are not helpful to prevent osteoporosis.
