Over the last several years, Vitamin K2 menaquinone 7 has been trending in consumer popularity and awareness thanks in large part to a growing body of scientific evidence supporting the positive benefits of Vitamin K2(MK7) for bone and cardiovascular health.
Our 100% natural Vitamin K2 (MK7) is produced from natto and manufactured by Japan Bioscience Labs (JBSL), a leading Japanese natto manufacturer for decades. JBSL Vitamin K2 (MK7) boasts superior quality, attractive pricing and a fermentation expertise second to none and is available as an oil or powder.
Despite contradictory data on vitamin K supplementation and bone health, the European Food Safety Authorities (EFSA) accepted the health claim on vitamin K’s role in maintenance of normal bone. In line with EFSA’s opinion, we showed that 3-year high-dose vitamin K1 (phylloquinone) and K2 (short-chain menaquinone-4) supplementation improved bone health after menopause.
Because of the longer half-life and greater potency of the long-chain MK-7, we have extended these investigations by measuring the effect of low-dose MK-7 supplementation on bone health.
MK-7 intake significantly improved vitamin K status and decreased the age-related decline in BMC and BMD at the lumbar spine and femoral neck, but not at the total hip. Bone strength was also favorably affected by MK-7. MK-7 significantly decreased the loss in vertebral height of the lower thoracic region at the mid-site of the vertebrae.
MK-7 supplements may help postmenopausal women to prevent bone loss. Whether these results can be extrapolated to other populations, e.g., children and men, needs further investigation.
