10 Best Vitamin K2 Supplements in 2026

A 125 mcg dose of vegan D3 paired with 100 mcg of MK-7 K2 creates a potent, once-daily formula for directing calcium. This combination is ideal for anyone prioritizing a strictly plant-based, allergen-conscious supplement routine without compromising on clinical-strength dosing. The inclusion of coconut MCT oil is a thoughtful touch for bioavailability, and the third-party testing provides a layer of confidence that’s hard to overlook.

The trade-off is the singular focus on MK-7, which is excellent for sustained activity but lacks the immediate-use profile of MK-4 found in blends like InnovixLabs Full Spectrum Vitamin K2. For a dedicated vegan seeking a clean, synergistic D3 and K2 combo from a transparent brand, this formula is exceptionally well-executed. It’s a straightforward choice that does exactly what the label promises, without the filler.

The 4,000 IU of vitamin D3 is a decisive feature for anyone whose bloodwork indicates a significant deficiency and who needs a substantial boost for immune and seasonal wellness support. This formula suits someone prioritizing bone and arterial health through the synergistic action of D3 and K2, specifically seeking a product from a brand that emphasizes purity and rigorous testing over marketing flair. It’s a logical choice for the skeptical tinkerer who values documented manufacturing controls.

One limitation is the lack of transparency around the K2 component, since it’s unclear if you’re getting the rapid-acting MK-4 or the longer-lasting MK-7, or at what dose. For someone whose protocol requires fine-tuning K2 intake specifically, this bundled approach is a black box. In that case, a product like the InnovixLabs Full Spectrum Vitamin K2, which explicitly details its MK-7 and MK-4 content, would be a more precise tool for the job.

The 600 mcg full-spectrum blend of MK4 and MK7 is the central feature, designed to support calcium transport to bones and arteries comprehensively. This makes it a strong candidate for someone specifically seeking the combined, researched benefits of both K2 forms in one supplement, rather than just MK7. The use of the bioactive trans isomers and third-party testing adds a layer of reliability for the detail-oriented buyer who prioritizes verified ingredient quality.

Its focus is singular. While the balanced K2 spectrum is thorough, it doesn’t include vitamin D3, a common and synergistic pairing found in products like Pure Encapsulations Vitamin D3 & K2. For someone wanting that combined convenience, this means taking an extra pill. However, for protocol tinkerers who dose D3 separately or whose bloodwork already shows sufficient levels, this standalone K2 formula offers precise control over each nutrient’s intake.

With 5000 IU of Vitamin D3 and 100 mcg of K2 MK-7 per serving, this Nutricost formula provides a substantial dose for supporting bone and immune health. The bottle contains 120 softgels, which is a long-lasting supply for daily use. Like other combination products, it offers both vitamins in one, avoiding the need for separate purchases.

This supplement uses only the MK-7 form of Vitamin K2. For individuals seeking the different MK-4 form or a blend like InnovixLabs Full Spectrum Vitamin K2, this product will not meet that need. It provides a specific combination of D3 and K2 MK-7, which is also available from other brands such as NOW Supplements.

The inclusion of both K2 MK-4 and MK-7 alongside K1 makes this a comprehensive formula for those focused specifically on calcium balance and vascular health. It’s designed for the user who wants to cover all the vitamin K bases with a single daily softgel, backed by a brand that emphasizes scientific formulation. This approach suits someone methodically building a supplement protocol who prefers separate, targeted nutrients over bundled combinations.

This supplement focuses exclusively on vitamin K, providing K1 and two forms of K2, which means you’ll need a separate product if your health regimen also includes vitamin D. Unlike combined formulas such as Pure Encapsulations Vitamin D3 & K2, it offers dedicated support for cardiovascular and bone health through calcium balance. This single-nutrient approach gives users the flexibility to manage their intake of each vitamin independently.

The metered dispenser delivers individual drops, which is the core reason this formula stands out for anyone who needs exact control over their intake or struggles with capsules. It combines vitamin D3 with K2 as MK-4, a pairing aimed at directing calcium properly, and carries NSF certification, so you know what’s on the label is in the bottle. This setup is ideal for the meticulous user who values precision and third-party verification above all else, preferring to adjust a drop at a time rather than commit to a fixed capsule dose.

This liquid uses MK-4, a specific form of vitamin K2 with a shorter activity window in the body compared to the MK-7 found in options like Sports Research Vegan Vitamin D3 K2 MK-7. That means more frequent dosing may be needed for a sustained effect. For someone prioritizing a once-daily routine with a longer-acting form, a capsule-based MK-7 product might be a more practical fit, even without the fine-tuned dosing control this dropper provides.

A 180 mcg dose of MK-7 is a serious commitment to arterial and bone health support. This product bundles that with a substantial 5000 IU of vitamin D3, creating a straightforward two-in-one protocol. The 120-capsule count provides a solid supply for consistent daily use.

The fixed 5000 IU D3 to 180 mcg K2 ratio means you cannot adjust the dosage of one nutrient independently. This product is designed for individuals who want both vitamins in this specific, high-strength combination and prefer the convenience of a single capsule.

The soy-free MenaQ7 MK-7 is the key here, a trademarked form chosen for its bioavailability and specific role in arterial calcium metabolism. This makes it a precise pick for anyone needing to avoid soy derivatives while targeting cardiovascular and bone health through proper K2 supplementation. The 120 vegan capsules and a slate of clean certifications, from Non-GMO to Kosher, reflect a product designed for purity-conscious users who prioritize a straightforward, high-quality K2 source.

A key consideration is its singular focus on delivering only K2. If you’re following a protocol that pairs it with vitamin D3, you’ll need a separate product. For a combined formula in a similar vegan, soy-free profile, the Sports Research Vegan Vitamin D3 K2 MK-7 includes both nutrients in one capsule, which simplifies a daily stack. NOW’s own Mega D-3 & MK-7 offers a much higher 180 mcg K2 dose alongside D3, catering to different dosing preferences.

Providing three clinically studied types of vitamin K in one capsule, this comprehensive formula simplifies supporting both bone and cardiovascular health. It’s designed for someone seeking a dedicated K complex without added nutrients, from a brand trusted by over 100 professional sports teams and recommended by practitioners. The product is also third-party certified, verifying the contents match the label and are free from unsafe contaminant levels.

As a standalone vitamin K product, it requires pairing with separate vitamin D and magnesium supplements to fully support the bone health functions described. This differs from combined formulas like Pure Encapsulations Vitamin D3 & K2. For a targeted, certified K blend from a clinically trusted source, it remains a solid choice, though achieving complete bone health protocols demands more deliberate supplement stacking.

A 100mcg dose of MK-7 in each softgel provides the form noted for longer bloodstream retention, which matters for consistent bone support protocols. This pick suits anyone prioritizing a strictly plant-based, soy-free supplement routine. The inclusion of coconut MCT oil addresses the fat-soluble nature of K2, so you don’t need to pair it with a meal for basic absorption. The vegan certification and third-party testing offer clear answers for the ingredient-skeptical buyer.

This supplement delivers a pure, high-bioavailability MK-7 form, which is noted for remaining active in the bloodstream longer than some other types. It does not include MK-4, a component found in broader-spectrum formulas like the one from InnovixLabs. The formula is purposefully streamlined for those seeking a dedicated vegan MK-7 source, and it incorporates coconut MCT oil to aid absorption since K2 is fat-soluble.
