The Claim
Daily supplementation with 375 μg of vitamin MK-7 for three years has no significant effect on the rate of bone mineral density decline at the lumbar spine, femoral neck, or total hip in postmenopausal women with osteopenia, regardless of concurrent calcium and vitamin D intake.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 375 micrograms of vitamin MK-7 every day for three years does not change how quickly bone density decreases in the spine, hip, or femoral neck in postmenopausal women with low bone density, even when they also take calcium and vitamin D.
See the scientific wording
Supplementation with 375 μg of vitamin MK-7 daily for three years has no significant effect on the rate of bone mineral density decline at the lumbar spine, femoral neck, or total hip in postmenopausal women with osteopenia when compared to placebo, despite concurrent calcium and vitamin D intake.
Vitamin MK-7 activates a protein-making process in bone cells that helps a bone protein bind to minerals, but this activation does not slow down the natural loss of bone density in postmenopausal women with low bone mass, even when they take calcium and vitamin D.
What the research says
1 studyTaking 375 micrograms of vitamin MK-7 every day for three years didn't help slow down bone loss in the spine or hips of postmenopausal women who were already taking calcium and vitamin D — their bones got just as weak as those who took a placebo.
