Time-dependent Effects Of Vitamin K2 (menatetrenone) On Bone Metabolism In Postmenopausal Women
Notes for this study:
|Number of Subjects
1,500mcg of MK-4 daily for four weeks in postmenopausal women at risk for bone loss was able to unreliably increase serum levels of phylloquinone but failed to influence vitamin D status.
Dietary records suggest that vitamin K supplementation did not alter food intake, and MK-4 was able to carboxylate marker proteins and thus was said to act as a vitamin.
