Vitamin K2 + D3, 120 Capsules vs Vitamin K2 MK-7, 100 mcg, 240 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

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
