HelloPharmacist Scorecard of MK-7 by Ubervita

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 20, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: vitamin K2. Vitamin K2 is a fat-soluble vitamin that plays a role in blood clotting and bone health.

The capsule itself is made from vegetable material, and rice flour is included as an inactive ingredient.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: vitamin K for bone and cardiovascular health.
  • We looked for evidence on: Cardiovascular disease (CVD), Hemorrhagic disease, Hypoprothrombinemia, Osteoporosis, Vitamin K-dependent clotting factors deficiency (VKCFD), Warfarin anticoagulation — and 3 related terms.
  • The strongest evidence on file: Vitamin K is rated "Effective" for Hemorrhagic disease (Natural Medicines).
  • Also on file: Vitamin K is rated "Effective" for Hypoprothrombinemia, Warfarin anticoagulation, Vitamin K-dependent clotting factors deficiency (VKCFD).
  • Also on file: Vitamin K is rated "Possibly Effective" for Osteoporosis.

Vitamin K2 is effective for treating vitamin K deficiency conditions and low prothrombin levels (hypoprothrombinemia), as well as hemorrhagic disease. For osteoporosis, the evidence is currently rated as possibly effective—meaning there's some promise, but more research is needed to confirm a real benefit.

The evidence, ingredient by ingredient Vitamin K

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Taken by mouth, vitamin K is generally well tolerated. The most common side effects are mild: diarrhea, nausea, and stomach upset.

The data shows these are relatively infrequent. Because normal dietary amounts of vitamin K are fine, but supplemental doses can shift how blood thinners work, it's important to check with your doctor before adding a vitamin K supplement to your routine.

Side effects, ingredient by ingredient Vitamin K

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Vitamin K.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 2 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with your doctor or pharmacist before taking this product if you use warfarin (Coumadin) or any other blood thinner. Vitamin K2 can reduce how well these medications work, and your anticoagulation will need to be monitored if your doctor decides it's safe to proceed together.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Ubervita's MK-7 is a straightforward vitamin K2 supplement suited for people who need to correct a vitamin K deficiency or are interested in bone health support. If you take blood thinners like warfarin, you'll need to confirm with your doctor or pharmacist before starting it—this is not a product you can simply add on your own.

Talk it over with your own healthcare provider to make sure it fits your health picture.

MK-7 by Ubervita: Common Questions

Does MK-7 by Ubervita interact with any medications?
Yes. Based on its ingredients, MK-7 has a known interaction with 2 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
MK-7 contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this interact with my blood thinner?
Yes—if you take warfarin, this product is a Major interaction concern. Vitamin K can weaken warfarin's blood-thinning effect. Check with your doctor or pharmacist before starting it; they may need to monitor your blood clotting if you do take both together.
What side effects might I have?
The most common are mild stomach effects: diarrhea, nausea, and abdominal pain. Serious side effects are rare when taken by mouth. Most people tolerate it well.
Is vitamin K2 safe during pregnancy or while breastfeeding?
The data shows vitamin K is likely safe in pregnancy and lactation. That said, any supplement in pregnancy deserves a conversation with your doctor—they know your full picture and can advise you on whether this one makes sense for you.
What does vitamin K actually do?
It's essential for blood clotting and also plays a role in bone health. This product is effective for treating vitamin K deficiency and related bleeding disorders, and may help with osteoporosis, though the bone benefit needs more study.
Does this have any fillers or other stuff I should know about?
Beyond the vitamin K2, there's a vegetable capsule and rice flour to make the capsule work—both are inactive ingredients. Nothing fancy, just the basics you need to take the supplement.
