HelloPharmacist Scorecard of Vitamin K2 MK7 Softgels 100 mcg by BulkSupplements.com

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 K2 (MK7 form) at 100 micrograms per softgel. Vitamin K2 is a fat-soluble vitamin that plays a role in bone health and blood clotting.

The inactive ingredients are soybean oil, gelatin, glycerin, and purified water — all standard softgel capsule components.

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: Bone and cardiovascular health support.
  • We looked for evidence on: Cardiovascular disease (CVD), Osteoporosis, Hemorrhagic disease, Hypoprothrombinemia, 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.

The evidence supports vitamin K for treating vitamin K-dependent disorders like certain bleeding conditions and clotting factor deficiencies. It's also effective for managing warfarin-related anticoagulation when medical supervision is involved.

For bone health and osteoporosis, the evidence is less established — the data rates it as possibly effective, meaning there's some promise but not yet strong proof.

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 in healthy people at typical dietary and supplement doses. The most common mild side effects are nausea, stomach upset, and diarrhea.

That said, check with your doctor before taking a supplement, since even food sources of vitamin K can affect certain medications and health conditions. The safety data we hold rate vitamin K as likely safe in pregnancy and breastfeeding, but talk to your provider about whether this supplement is right for you during those times.

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.

The major concern is blood thinners (anticoagulants), especially warfarin — vitamin K directly reverses its effects. If you take any blood thinner at all, check with your pharmacist or doctor before using this supplement.

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.

This is a straightforward vitamin K2 supplement that works well for its intended uses — mainly for bleeding or clotting disorders under medical care. If you're on a blood thinner like warfarin, do not take this without your doctor's approval; vitamin K directly undermines these medications.

If you're generally healthy and not on blood thinners, chat with your pharmacist before starting to make sure it fits your situation.

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.
Can I take this if I'm on warfarin or another blood thinner?
Not without talking to your doctor first. Vitamin K directly opposes how blood thinners work and can reduce their effectiveness, which is a serious safety issue. Your prescriber needs to know if you want to start this supplement.
What side effects might I notice?
Most people have no problems, but some experience mild nausea, stomach upset, or diarrhea when taking vitamin K by mouth. These are usually mild and go away on their own.

The evidence rates vitamin K as likely safe during pregnancy and lactation. Still, talk with your doctor or midwife before adding any supplement during these times — they know your full health picture.
What does vitamin K2 actually do?
Vitamin K is essential for blood clotting and plays a role in bone health. This form (MK7) is thought to be well absorbed and active in both processes.
Does this work for osteoporosis?
The evidence is not yet strong enough to say for sure. Some research suggests vitamin K may help bone health, but more proof is needed — the data rates it as possibly effective.
