HelloPharmacist Scorecard of K-2 MK-7 Raspberry by KAL

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 Jul 11, 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 K in the MK-7 form. Vitamin K is essential for the body's clotting factors (proteins that help blood clot) and is also involved in bone metabolism.

The inactive ingredients—mannitol starch complex, maltodextrin, natural flavors, cellulose, and others—are fillers and binders used to form the tablet and add taste.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Bone health support.
  • We looked for evidence on: Osteoporosis, Bone density, Bone strength, Fracture prevention.
  • The strongest evidence on file: Vitamin K is rated "Possibly Effective" for Osteoporosis (Natural Medicines).

The evidence supports vitamin K for treating clotting factor deficiencies and conditions like hypoprothrombinemia and hemorrhagic disease. For osteoporosis, the evidence is less established — we rate it possibly effective, meaning there's some promise but the data isn't conclusive enough yet.

If you're taking this for bone health, talk with your doctor about whether it's right for your specific situation and what else may help.

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.

These happen in a small number of people. Dietary amounts of vitamin K are safe for healthy people, but if you're considering supplements, it's worth checking with your doctor first — especially if you're on any medications.

Vitamin K is rated likely safe in pregnancy and lactation.

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.

If you take warfarin (Coumadin) or another blood thinner (anticoagulant), you must check with your pharmacist or doctor before using this product. Vitamin K significantly reduces how these medications work, and the effect can change how well your blood clotting is controlled.

The bottom line

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

This supplement is straightforward for people with clotting disorders or those not on blood thinners. If you take warfarin or another anticoagulant, do not use this product without checking with your pharmacist or doctor first — the interaction is serious and requires supervision.

Everyone else should run their medications through the checker on this page before starting.

When taken by mouth, vitamin K is generally well tolerated. The most common side effects are mild and include nausea, diarrhea, stomach upset, and abdominal pain. Serious side effects are very rare.
What is vitamin K used for?

Why is there such a big warning about blood thinners?
