10 Best Mk7 Supplements in 2026

The inclusion of vitamin K1 alongside both MK-7 and MK-4 forms of K2 provides a comprehensive approach to vitamin K supplementation, which is difficult to achieve through diet alone. This broad-spectrum formula is designed to support cardiovascular and bone health by helping direct calcium to the proper tissues. For someone prioritizing a complete K vitamin profile from a brand that emphasizes scientific formulation and provides a Certificate of Analysis, this product is a logical choice.

Life Extension Super K combines vitamin K1 with two bioavailable forms of K2, providing a comprehensive K complex for supporting heart, arterial, and bone health through calcium balance. This means it covers multiple bases within the vitamin K family, unlike single-form MK-7 supplements. However, it is a dedicated K formula, so a separate vitamin D3 supplement would be needed for a combined protocol, unlike products such as NOW Supplements Mega D-3 & MK-7.

This supplement combines 5000 IU of vitamin D3 with 180 mcg of vitamin K2 as MK-7, delivering both nutrients in one capsule for a consolidated routine. The formulation uses the MenaQ7 form of K2, which the brand notes is a soy-free, bioavailable type researched for roles in bone and cardiovascular health*. For someone already looking to take both vitamins, this product simplifies the process by bundling them together.

The 180 mcg of vitamin K2 is a fixed amount paired with the D3. For comparison, the standalone Doctor’s Best Vitamin K2 MK-7 with MenaQ7 provides 100 mcg per serving. This means the combo product offers a higher K2 dose, but it also locks your intake into that specific ratio, which could be either convenient or inflexible depending on your individual regimen.

Doctor’s Best Vitamin K2 MK-7 focuses on the MenaQ7 ingredient, a form of vitamin K2 sourced from fermented chickpeas. The brand states this form is bioavailable and remains in the body longer than other forms, which means the body can absorb and use it effectively. This makes it a straightforward choice for someone seeking a dedicated vegan K2 supplement from a company that emphasizes clinically-approved formulas.

The trade-off is the serving size and bottle count. At 100 mcg per capsule, it’s a moderate dose, which some may prefer for maintenance, but those following higher-dose protocols will need to take more. The 60-capsule supply also runs out quicker than larger bottles from brands like Bronson. Compared to a combo product like NOW Supplements Mega D-3 & MK-7, this is a pure play, letting you control each nutrient individually.

A single daily softgel provides 100 mcg of Vitamin K2 as MK-7, the form noted for high bioavailability. This simplifies supplementing for bone and heart support without complex dosing. Sourced from fermented chickpeas and housed in a carrageenan-free Plantgel capsule, the formula is a soy-free, vegan option for those with specific dietary preferences. Coconut MCT oil is added because K2 absorbs best with fat, so the supplement can be effective even when taken separately from a meal.

This product’s focus is its purity as a single-ingredient MK-7 supplement. If your needs call for the combined benefits of both MK-7 and the shorter-acting MK-4 form, like those in Life Extension Super K, this isn’t the bottle. It’s a focused tool for someone who wants a clean, plant-derived MK-7 source to pair precisely with an existing D3 or calcium regimen, without extra ingredients.

This supplement provides 300 mcg of vitamin K2, using the MenaQ7 MK-7 form. That higher dose suits users looking for a soy-free source and stronger support for bone and cardiovascular health.* It comes from NOW Foods, a company operating since 1971, and carries an NPA A-rated GMP certification. This means its entire manufacturing process has been examined for quality controls, which matters to buyers who prioritize documented production standards.

This is a specialized tool. It doesn’t bundle in other nutrients, unlike the NOW Mega D-3 & MK-7 which includes vitamin D, so you’re committing to managing a separate protocol. For someone still dialing in their regimen, a lower-dose option such as Doctor’s Best Vitamin K2 MK-7 with MenaQ7 might be a more cautious starting point before stepping up to this extra-strength version.

A 120-tablet supply positions this as a workhorse for anyone committed to long-term K2 supplementation. It’s built for the user who wants to stock the cabinet and not think about reordering for months. The brand’s focus on cGMP certification and a clean, allergen-free formula means you’re getting a straightforward, no-nonsense MK-7 option from a manufacturer with a long history. It suits the person who values consistency and a simple, high-count bottle over chasing the absolute highest single dose.

This supplement provides 100 mcg of Vitamin K2 MK-7 per tablet, which is a standard daily maintenance dose. For comparison, some other brands offer higher single-serving potencies, like Swanson’s 200 mcg softgels or NOW Foods’ 300 mcg capsules. The Bronson product is a tablet, while several competitors on the market use softgel or capsule formats.

This formula delivers 125 mcg of vegan D3 paired with 100 mcg of K2 as MK-7, a combination designed to work together for bone and immune support by managing calcium absorption and placement. Its plant-based credentials are explicit, with D3 from lichen and K2 from fermented chickpeas, making it a definitive option for vegans. The addition of coconut MCT oil aims to improve nutrient absorption, and its Vegan Certified and Non-GMO Project Verified status provides clear ingredient standards.

Consider the specifics of its K2 content. The 100 mcg of MK-7 is a solid maintenance dose, but it’s less than what you’ll find in dedicated K2 supplements like NOW Foods 0994 Mk7, which offers 300 mcg per capsule. This combo also forgoes the MK-4 form of vitamin K2 entirely. For someone whose primary goal is a high-potency, full-spectrum K2 regimen, a specialized product would be a better fit.

The 100 mcg dose of soy-free MenaQ7 MK-7 makes this a precise, single-ingredient choice for anyone specifically targeting cardiovascular and bone health without soy-derived vitamin K. It suits the meticulous supplement user who values a clean, third-party-audited manufacturing process and needs a formula free from common allergens. The extensive certifications provide clear documentation for restrictive diets, which is helpful for those who have to scrutinize every label.

The trade-off for that purity and focused dose is that you miss out on the synergistic benefits of a combined D3/K2 formula, like the one in NOW’s own Mega D-3 & MK-7. For someone who already gets ample D3 elsewhere, this is a non-issue. But if your goal is a higher-potency standalone MK-7, you’d need to compare the per-capsule cost against options like the NOW 0994, which packs 300 mcg per capsule for a more aggressive protocol.

Swanson Maximum Strength Vitamin K2 MK-7 delivers 200 mcg of MK-7 per softgel, a higher potency suited for protocols specifying that dose. Its K2 is sourced from natural Japanese natto, and Swanson has delivered science-backed products for over five decades from GMP-certified facilities. Each daily softgel is designed to support bone and cardiovascular wellness by helping regulate calcium.

The bottle contains 30 softgels, which defines a specific supply cycle. For comparison, the NOW Foods MK-7 300 mcg offers an even higher single-serving dose. A product such as Doctor’s Best Vitamin K2 MK-7 with MenaQ7 provides a more moderate 100 mcg, which could be a better starting point for initial experimentation. This Swanson product is for when you’re past that experimenting phase.

InnovixLabs delivers 600 mcg of vitamin K2 in a full-spectrum blend of both MK-4 and MK-7 forms, a combination designed to support calcium transport to bones over soft tissues. This single-product approach covers the essential K2 types mentioned for heart, bone, and brain support, which can simplify a regimen compared to taking two separate supplements. Third-party testing for each batch adds confidence that the capsule’s contents match its label.

Its formulation is specialized for K2 alone. A buyer who already uses a high-dose D3 supplement and seeks only MK-7 for calcium management might find a more targeted fit in a dedicated product such as Doctor’s Best Vitamin K2 MK-7 with MenaQ7. This InnovixLabs product is best suited for someone prioritizing a standalone K2 supplement that includes both MK-4 and MK-7.
