MK-7 Vitamin K-2, 100 mcg, 120 Veg Capsules vs Vitamin K2 + D3, Extra Strength, 120 Capsules

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

• ✓10,000 IU suits people with confirmed deficiency — multiple reviewers specifically switched from 5,000 IU after failing to hit target levels
• ✓K2 as MK-7 (120 mcg) is the superior form: long half-life means once-daily dosing works, and the dose sits in the effective range used in studies
• ✓Clean excipient list — microcrystalline cellulose, cellulose capsule, magnesium stearate, silicon dioxide — no soy, gluten, or fillers reviewers flag
• ✓120 capsules gives four months at daily use; reviewers consistently cite strong value versus pharmacy pricing

Cons

• ✗No independent third-party testing — label says 'Lab Tested' but this is self-declared; specs confirm no external verification
• ✗10,000 IU is not a maintenance dose — requires blood testing before and during use; one reviewer explicitly notes skipping this step and risking over-supplementation
• ✗D3 sourced from lanolin (standard cholecalciferol) — not suitable for vegans despite the cellulose capsule shell
• ✗K2 form is unbranded MK-7, not a patented ingredient like MenaQ7 — potency and purity can vary without third-party confirmation
