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

Pros

• ✓Uses branded MenaQ7® MK-7 form — the most bioavailable, longest-acting K2 variant with solid clinical backing
• ✓Exceptionally clean formulation: rice flour, ascorbyl palmitate (natural antioxidant), silicon dioxide — no unnecessary fillers
• ✓Vegan vegetable capsules; certified Non-GMO, Soy-Free, Kosher, GMP — broad allergen-free profile
• ✓100 mcg dose is the evidence-supported daily maintenance amount for D3 pairing and bone/vascular calcium regulation

Cons

• ✗60-capsule bottles last only 2 months at daily dosing — not a high-count economy size
• ✗Benefits (bone density, cardiovascular calcium regulation) are gradual and may not produce noticeable short-term effects
• ✗People on blood-thinning medications (e.g., warfarin) must consult a doctor — K2 directly affects coagulation pathways
• ✗A minority of Trustpilot reviewers raised concerns about Amazon third-party seller packaging integrity — buy from authorised retailers

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
