Matti Narkia on 07 Dec 09Effect of vitamin K2 (menaquinone-7) in fermented soybean (natto) on bone loss in ovariectomized rats. Yamaguchi M, Taguchi H, Gao YH, Igarashi A, Tsukamoto Y. J Bone Miner Metab. 1999;17(1):23-9. PMID: 10084398 This study demonstrates that the intake of dietary MK-7 has a preventive effect on bone loss caused by OVX. This effect may be partly caused by MK-4, which is formed by degradation of MK-7.
