Quick answer: Vitamin K2 (MK-7) is a form of vitamin K that helps activate proteins which guide calcium to bones and help keep it where it belongs. It pairs naturally with vitamin D3, which supports calcium absorption. PressPril includes vitamin K2 MK-7 to support the brand's focus on healthy circulation and vascular integrity.
Vitamin K often gets less attention than vitamins C or D, yet it plays a quietly important role every day. One form in particular, vitamin K2 as MK-7, has become a favorite in heart and circulation formulas. PressPril includes it as one of its seven named ingredients. In this guide we explain what vitamin K2 MK-7 is, how it relates to calcium and why it pairs so well with vitamin D3.
Vitamin K1 and K2: two members of one family
Vitamin K is not a single compound but a family. The two main members are:
- Vitamin K1 (phylloquinone): found mostly in leafy green vegetables like kale, spinach and broccoli.
- Vitamin K2 (menaquinones): found in fermented foods such as natto and some cheeses, and in smaller amounts in certain animal foods.
Within vitamin K2 there are several forms, labeled MK-4 through MK-13. MK-7 is a longer-chain form that is especially popular in supplements because it stays in circulation for a long time, which makes it well suited to a once-daily routine. The NIH Office of Dietary Supplements provides a helpful vitamin K fact sheet if you would like the full background.
How vitamin K2 relates to calcium
Calcium is famous for building strong bones and teeth, but it also has many other jobs around the body. The key is getting calcium to the right places. This is where vitamin K2 shines. It helps activate special proteins, including osteocalcin in bone and matrix Gla protein in vessel walls, that help guide calcium where it is needed and help keep it where it belongs.
Think of vitamin K2 as a traffic director for calcium. By supporting these proteins, it helps maintain healthy, flexible blood vessels and strong bones at the same time. That is why the brand includes it in a formula focused on vascular integrity and healthy blood flow.
The perfect partner: vitamin D3
Vitamin D3 helps your body absorb calcium from food. Vitamin K2 helps direct that calcium once it is in the body. Together, they form one of the best-known nutrient partnerships. PressPril includes both, so the pair works side by side in every capsule.
| Nutrient | Main role with calcium | Common food sources |
|---|---|---|
| Vitamin D3 | Supports calcium absorption | Sunlight, oily fish, egg yolks, fortified foods |
| Vitamin K2 (MK-7) | Helps guide calcium to bones and supports vessel health | Natto, some aged cheeses, fermented foods |

Why K2 can be hard to get from food
Natto, a traditional Japanese fermented soybean dish, is one of the richest food sources of MK-7, but it is not a regular part of most Western diets. Aged cheeses and other fermented foods contribute some vitamin K2, though amounts vary widely. For many people, a supplement that includes MK-7 is a convenient way to add this nutrient to an everyday routine.

Supporting vitamin K2 with your plate
Your daily meals can add to the vitamin K picture too. Leafy greens bring plenty of vitamin K1, while fermented foods contribute K2. Some easy ideas:
- Add a handful of spinach or kale to eggs, soups or pasta
- Enjoy a small portion of aged cheese with fruit
- Try sauerkraut or other fermented vegetables as a side
- Build colorful, plant-forward meals like those in our heart-friendly plate guide
Why the MK-7 form is so popular
Shorter forms of vitamin K2 leave the bloodstream fairly quickly. MK-7 lingers much longer, so a single daily capsule keeps a steady supply on hand. That long-lasting quality is exactly why the brand chose it for a simple one-a-day routine.
