MK-7 Vitamin K-2, 100 mcg, 120 V...
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
Vitamin K2 + D3, 120 Capsules
Pros
- ✓K2 supplied as MK-7 — the superior form for directing calcium away from arteries and into bone tissue
- ✓5,000 IU D3 is a proper therapeutic dose for correcting deficiency, not a token maintenance amount
- ✓Multiple reviewers report measurable improvements in vitamin D blood levels after switching to this product
- ✓Small capsule size and no aftertaste — frequently mentioned as making daily use easy
Cons
- ✗No independent third-party testing (NSF, USP, or equivalent) — the 'lab tested' label claim is manufacturer self-testing only
- ✗5,000 IU daily is above typical maintenance doses — not suitable for self-prescribing without a blood test first
- ✗K2 is contraindicated with warfarin and other anticoagulants, which the label warns about but users often overlook
- ✗Not vegan — D3 is almost certainly lanolin-derived despite the plant-based capsule shell
