NOW Foods MK-7 Vitamin K-2 vs Nutricost Vitamin K2 MK-7

Pros

• ✓Uses MenaQ7® — a patented MK-7 form with published clinical trial data, not generic menaquinone-7
• ✓100 mcg is the evidence-based daily dose for bone mineralisation and vascular calcium management
• ✓Small capsules consistently praised across reviews as tasteless, odourless, and easy to swallow
• ✓Soy-free despite K2 typically being derived from natto fermentation — clean excipient list too

Cons

• ✗Not independently third-party tested per product specs — quality relies on NOW Foods' own GMP processes
• ✗Requires medical consultation for anyone taking anticoagulants such as warfarin or heparin

Best For

Pros

• ✓240-capsule bottle makes this one of the cheapest per-serving K2 MK-7 options — repeatedly highlighted by reviewers as the primary buying reason
• ✓MK-7 form has a long half-life (~72 hours), making once-daily dosing genuinely effective rather than a convenience compromise
• ✓Small softgels with no taste or aftertaste — multiple reviewers with swallowing difficulties specifically flag this
• ✓Minimal ingredient list: MK-7, sunflower oil, gelatin capsule — no unnecessary fillers beyond the caramel capsule colouring

Cons

• ✗Gelatin capsules — not suitable for vegans or vegetarians
• ✗Caramel colouring in the capsule shell uses ammonia-based processing; flagged by at least one reviewer with multiple chemical sensitivities
• ✗One reviewer notes the brand does not publish isomer data — unclear what percentage is all-trans MK-7 (the active form) versus cis
• ✗Rare reports of heart palpitations and anxiety, particularly when combined with high-dose vitamin D3
