Background: Despite plausible biological mechanisms, the differential
abilities of phylloquinone (PK) and menaquinones (MKn) to prevent bone loss remain
controversial. The objective of the current study was to compare the effects of PK,
menaquinone-4 (MK-4) and menaquinone-7 (MK-7) on the rate of bone loss in
ovariectomized (OVX) Norway ... read morerats. A secondary aim was to compare the effects of
vitamin K with those of bisphosphonates (BP) on bone loss.
