Vitamin K2 (MK-7) — 100 mcg — 60 Veg Capsules — Bone & Cardiovascular Support*
Premium Vitamin K2 as Menaquinone-7 (MK-7, 100 mcg) in vegetarian capsules to support bone health, cardiovascular wellness, and optimal calcium metabolism. MK-7 is a long-acting K2 form (multi-day half-life) that activates key proteins (osteocalcin, MGP) to 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.*

Clinically Studied Benefits
✓ Supports arterial elasticity / vascular health — 3-year double-blind RCT in healthy postmenopausal women found MK-7 helped maintain arterial elasticity and improved pulse-wave velocity vs placebo.
NIH/PubMed — Knapen, 2015
✓ Helps maintain bone strength indices in aging — 3-year RCT showed MK-7 helped decrease age-related bone loss and improved bone quality parameters in postmenopausal women.
NIH/PubMed — Knapen, 2013
✓ Improves vitamin-K–dependent markers — Human trials show MK-7 reduces dp-ucMGP (inactive MGP), a biomarker linked with vascular stiffness/calcification risk.
NIH/PubMed — Theuwissen, 2012
Additional / Promising Evidence
✓ Vascular markers in metabolic conditions — 12-week double-blind RCT in adults with type 2 diabetes: MK-7 improved vitamin-K–status markers (dp-ucMGP).
NIH/PubMed — Vossen, 2023
✓ Arterial stiffness maintenance over one year — Placebo-controlled human trial (middle-aged/older adults) reported favorable changes in cfPWV and carotid measures with MK-7.
NIH/PubMed — Vossen, 2023
✓ Dental/craniofacial mineralization (K-dependent proteins) — Human-focused evidence links K-activated proteins with tooth mineralization; interventional data are emerging.
NIH/PubMed — Maresz, 2020
University / Academic Context
✓ Maastricht University (Netherlands) — Vascular elasticity — 3-year RCT showed MK-7 improved arterial stiffness metrics vs placebo.
NIH/PubMed — Knapen, 2015
✓ Maastricht University — Bone quality — 3-year RCT found MK-7 helped decrease bone loss and improved bone strength indices.
NIH/PubMed — Knapen, 2013
✓ Erasmus University (Rotterdam Study) — Heart health (observational) — Higher dietary K2 intake was associated with lower coronary heart disease risk and less aortic calcification.
NIH/PubMed — Geleijnse, 2004
Global Evidence & Reviews
✓ NIH ODS — Vitamin K — Health-professional monograph on roles, intakes, interactions, and safety (includes K2/MK-7).
NIH/ODS — Vitamin K
✓ Balanced context (concise, non-scary) — Evidence is strongest for MK-7 effects on vitamin-K–dependent markers (dp-ucMGP) and arterial stiffness in specific adult groups; hard-endpoint trials remain limited. If you take anticoagulants, consult your clinician.
