Check Price on Amazon

Total K2 stands apart because it combines MK-4, MK-7, and K1 into a single vegan capsule with 620 mcg of total K2 — an unusually broad spectrum for a product in this space. The MK-7 comes from MenaQ7, the patented all-trans form used in most published cardiovascular research, so you know the isomer is the one that activates matrix Gla-protein effectively. The inclusion of K1 provides additional coagulation support often missing from K2-only formulations.

The daily dose also supplies 125 mcg of vitamin D3 as a cofactor, completing the calcium-shuttling circuit without requiring a second bottle. Organic certification adds a layer of purity verification that matters for long-term daily supplementation. The 60-capsule count provides two months of coverage at one capsule per day.

For anyone who wants the full vitamin K family in a single serving — K1, MK-4, and MK-7 — paired with D3 and backed by a patented ingredient, this is the most complete option on the list. The only real trade-off is that the broad spectrum comes in a larger capsule size that some people find less easy to swallow.

Andrew Lessman’s K2 MK-7 is the cleanest capsule you will find in this category — no binders, fillers, lubricants, flowing agents, preservatives, or artificial colors. Each easy-to-swallow capsule delivers exactly 120 mcg of the MK-7 form, the dosage used in studies showing improved arterial stiffness markers. The formula is non-acidic, which matters for anyone with a sensitive digestive system who reacts poorly to typical tablet-based supplements.

The production facility runs 100 percent solar power with zero carbon footprint, and the bottles use 100 percent recyclable post-consumer resin. This level of environmental commitment is rare in the supplement industry and reflects a manufacturing ethos focused on purity from raw material through final capsule. The product also contains zero common allergens — no soy, dairy, gluten, or corn.

If your priority is a single-ingredient MK-7 supplement with a well-studied dose and no chemical processing aids, this is the benchmark. The trade-off: there is no D3 cofactor, so you will need to source that separately, and the 60-capsule bottle lasts only two months at the standard serving.

This product solves the cofactor problem directly by pairing 180 mcg of K2 MK-7 with 5000 IU of vitamin D3 in a single vegetable capsule. The K2 dosage is slightly above the typical 90–120 mcg range, which provides a buffer if your dietary intake is low. The D3 level at 5000 IU is on the higher side, so it is best suited for individuals who know they are deficient or who get minimal sun exposure.

MenaQ7 is the source of MK-7 here again, meaning you get the same patented all-trans form used in cardiovascular research. The vegetable capsule base avoids gelatin, making it suitable for vegetarians. The 60-capsule count provides two months of daily use at one capsule per serving.

This is the straightforward pick if you want the D3-K2 pairing in one bottle without needing a separate D3 supplement. The main consideration is that 5000 IU of D3 per day may be more than some individuals require, and the formulation does not include MK-4 or K1, so it is a focused dual-ingredient approach rather than a broad spectrum.

DEAL SUPPLEMENT delivers 600 mcg of combined MK-7 and MK-4 per softgel — a dose well above typical maintenance levels — suspended in a virgin coconut oil base that enhances absorption of these fat-soluble vitamins. The dual-form approach provides both the long-acting coverage of MK-7 and the rapid tissue uptake of MK-4, theoretically offering both sustained arterial protection and acute cellular access.

The 180-count bottle provides a six-month supply at one softgel per day, making the per-dose cost exceptionally low for a dual-form, oil-based supplement. Third-party lab testing confirms the stated potency, and the formula avoids gluten, dairy, eggs, soy, and yeast. The manufacturer specifically calls out benefits for bone density, heart health, and calcium processing.

For anyone looking to maximize K2 intake across both forms while keeping the cost per serving minimal, this bottle stretches further than any other on the list. The only hesitation is that 600 mcg may be more than necessary for simple maintenance — and the softgels are moderate in size, though the coconut oil helps them slide down more easily than dry capsules.

BulkSupplements offers a straightforward 100 mcg MK-7 softgel in a 365-count bottle, providing a full year of daily supplementation at a single purchase. The dosage sits right at the lower end of the range used in cardiovascular studies, making it a solid maintenance option for someone who already gets some K2 from diet or just wants basic arterial calcium protection without going overboard on dosing.

The softgel format uses a gelatin shell — not ideal for vegetarians, but standard for budget-friendly bulk supplements. The product is labeled gluten-free, and BulkSupplements is known for keeping raw ingredient costs low by selling direct to consumers without intermediary branding. Each softgel is one serving, so the math is simple: one bottle, one year, one softgel per day.

Where this makes sense is for cost-conscious users who want a straightforward MK-7 dose without added cofactors or proprietary blends. The downside is the 100 mcg dose is at the low threshold of studied cardiovascular benefits — users wanting stronger arterial support may need a higher potency product — and there is no D3 pairing, so that will need a separate purchase.
