NOW Foods MK-7 Vitamin K-2 100mc...

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

Adults supplementing vitamin D3 at any dose People taking calcium supplements seeking proper bone deposition Vegans and vegetarians needing a plant-based K2 source Over-40s focused on bone density and arterial health Those with soy, gluten, or dairy sensitivities Anyone wanting a single-ingredient, no-fuss K2 capsule

Vitamin K2 + D3, Extra Strength,...

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

Best For

Adults with blood-confirmed vitamin D deficiency who haven't responded to 5,000 IU doses People in northern climates or desk-bound lifestyles with minimal sun exposure Anyone seeking a combined bone and calcium metabolism formula without paying for a premium brand Budget-conscious buyers who want MK-7 specifically rather than cheaper MK-4 products

What does the data say about NOW Foods MK-7 Vitamin... vs Vitamin K2 + D3, Extra...?

Both use MK-7 rather than the cheaper MK-4 form of K2, but the two products serve different purposes. NOW Foods delivers 100mcg MK-7 as a standalone supplement using branded MenaQ7® extract in a clean veg capsule — rice flour and ascorbyl palmitate, nothing else worth noting. Futurebiotics pairs 100mcg MK-7 with 10,000 IU of vitamin D3 as cholecalciferol. That's a therapeutic D3 dose. Reviewers report corrected deficiencies confirmed by blood tests, but 10,000 IU daily without monitoring creates a genuine toxicity risk over months.

Pick NOW Foods (85/100, £21.99 for 60 caps) if you already take D3 and want an independently tested K2 source. It carries Non-GMO, Soy-Free, Kosher, and GMP certification — useful if allergens or quality assurance matter to you. At 60 capsules, it lasts two months at daily dosing, around 37p per capsule.

Futurebiotics (78/100, £14.72 for 120 caps) costs considerably less per dose and the four-month supply is practical. The 'Lab Tested' label is in-house only — no NSF, USP, or Informed Sport verification. It makes sense if you have a confirmed vitamin D deficiency and want both nutrients in one capsule. For people already at adequate D3 levels, 10,000 IU daily is too high a dose to take unsupervised.

NOW Foods MK-7 Vitamin K-2 100mcg - 60 Veg Capsules Winner 85.0/100

NOW Foods MK-7 Vitamin K-2 100mcg is a well-regarded standalone K2 supplement using the branded MenaQ7® menaquinone-7 form, which reviewers consistently praise for its superior bioavailability and longer half-life compared to MK-4.
