Vitamin K2 (MK-7) 75 mcg + Vitamin D3 2,000 IU β 90 Chewable Tablets β Bone & Cardiovascular Support*
Synergistic Vitamin K2 (MK-7, 75 mcg) and Vitamin D3 (2,000 IU) in a great-tasting cherry chewable to support bone density, calcium balance, and cardiovascular health.* D3 supports calcium absorption; K2 activates proteins (e.g., osteocalcin, MGP) that direct calcium to bones & teeth while helping keep arteries flexible.* Produced in FDA-registered, GMP-certified facilities and
3rd-party tested for identity, potency & purity.* If you use blood-thinning medications, consult your healthcare professional.*
Research Promise: At Lifesource Vitamins, our commitment is rooted in research and results. Every benefit below is supported by human clinical studies indexed in the National Institutes of Health (NIH) via PubMed, with full texts available in the National Library of Medicine (NLM) PubMed Central (PMC) when available. In addition, we reference reviews from 39 leading health organizations and insights from 20 top global universities to ensure our guidance aligns with credible science.*
Clinically Studied Benefits (with research)
β’ Bone health & calcium balance* β Vitamin D3 supports calcium absorption; Vitamin K2 (MK-7) activates osteocalcin for bone mineralization. (NIH/ODS β Vitamin D; NIH/ODS β Vitamin K)
β’ Arterial elasticity / vascular health (MK-7)* β 3-year RCT in healthy postmenopausal women: MK-7 improved measures of arterial stiffness and reduced inactive MGP, a calcification marker. (NIH/PubMed β 2015 RCT)
β’ Bone quality parameters (MK-7)* β Multi-year RCTs show favorable effects on bone strength indices in postmenopausal women. (NIH/PubMed β 2013 RCT)
β’ Immune support (D3; greatest in deficiency)* β Individual-participant meta-analysis found vitamin D supplementation reduced acute respiratory infection risk, with the largest benefit in those who were deficient. (NIH/PubMed β BMJ 2017)
β’ Vascular calcification markers (K-dependent proteins)* β Human studies show K2 lowers dp-ucMGP (inactive MGP), a biomarker linked with arterial stiffness. (NIH/PMC β 2017 review with human data)
Additional Studies Showing Promising Benefits*
β’ Dental/craniofacial mineralization (K-dependent proteins)* β Human-focused evidence links K-activated proteins with tooth mineralization and caries risk; interventional data remain emerging. (NIH/PMC β 2020 review (human-focused))
β’ Falls & muscle function (D3; mixed)* β Reviews indicate context-dependent effects of vitamin D on falls/muscle, with benefit most likely in deficient older adults. (NIH/PubMed β Cochrane 2011)
β’ Metabolic health (D, K observational + small RCTs; heterogeneous)* β Human studies explore insulin sensitivity and glucose markers; results vary by baseline status and dosing. (NIH/PubMed β 2019 human evidence)
University Studies (Promising β Human / Academic Research)
β’ Maastricht University (Netherlands) β Vascular elasticity (MK-7)* β 3-year double-blind RCT in healthy postmenopausal women: MK-7 improved carotidβfemoral pulse-wave velocity and lowered inactive MGP (dp-ucMGP). (NIH/PubMed β 2015)
β’ Maastricht University (Netherlands) β Bone strength indices (MK-7)* β 3-year RCT showed MK-7 attenuated age-related decline in BMD-related strength measures in postmenopausal women. (NIH/PubMed β 2013)
β’ Erasmus University (Rotterdam Study) β CHD risk & aortic calcification (dietary K2)* β Prospective cohort: higher menaquinone (K2) intake was associated with lower coronary heart disease risk and less aortic calcification. (NIH/PubMed β 2004)
β’ Dutch academic centers β Vascular markers (MK-7)* β RCTs report MK-7 reduces dp-ucMGP and can help maintain arterial stiffness (PWV) vs placebo over 12 weeks. (NIH/PubMed β 2023)
β’ Japanese university-led RCT β Osteocalcin carboxylation (MK-7)* β Dose-finding double-blind trial: low-dose MK-7 improved osteocalcin Ξ³-carboxylation (a vitamin-Kβdependent bone marker). (NIH/PubMed β 2015)
Global Evidence & Authoritative Reviews*
β’ NIH ODS β Vitamins D & K β Health-professional monographs on roles, intakes, interactions, and safety. (NIH/ODS: Vitamin D; NIH/ODS: Vitamin K)
β’ Balanced context (concise, non-scary) β Evidence is strongest in individuals with low vitamin D status and for K-responsive markers (dp-ucMGP). Use as directed; consult your clinician if you take anticoagulants. (NCCIH β Vitamin D)
We monitor research from the worldβs leading institutions β including Harvard, Johns Hopkins, Mayo Clinic, Cleveland Clinic, Cambridge University, Oxford, Stanford, Yale, MIT, the University of Florida, Oregon State University β Linus Pauling Institute, Tufts, Boston University, Cornell, Columbia, and Ohio State β to ensure our guidance remains aligned with the highest standards of credible science.*
