HelloPharmacist Scorecard of Vitamin K2 MK-7 Gold 120 mcg by NutriGold

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, at 120 mcg per capsule. The capsule also contains inactive ingredients — tapioca maltodextrin, cellulose, and dicalcium phosphate — which are fillers and binders.

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: Supports bone, heart, and dental health.
  • We looked for evidence on: Cardiovascular disease (CVD), Osteoporosis, Prostate cancer, Bone density, Vascular calcification, Arterial health.
  • The strongest evidence on file: Vitamin K is rated "Possibly Effective" for Osteoporosis (Natural Medicines).
  • Also on file: Vitamin K is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD), Prostate cancer.

Vitamin K is effective for treating vitamin K deficiency, vitamin K-dependent clotting factor deficiency, and hemorrhagic disease (a bleeding disorder). It's also effective for managing warfarin anticoagulation (meaning your doctor may use it to adjust your blood thinner if needed).

For osteoporosis, the evidence suggests it may help, though the data is still being gathered.

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 the amounts found in food and most supplements. The most common side effects are mild — nausea, diarrhea, and stomach upset.

Serious side effects from oral vitamin K are rare. The data shows vitamin K is likely safe in pregnancy and while breastfeeding, though you should still check with your doctor before starting any supplement 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.

Check with your pharmacist or doctor before using this product if you take warfarin (Coumadin) or any other blood thinner (anticoagulant). Vitamin K can reduce how well these drugs work and may need your dose adjusted.

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.

If you're not on blood thinners and don't have a clotting disorder, this is a straightforward supplement to consider for bone health support. If you take warfarin or any other anticoagulant, you absolutely must talk with your pharmacist or doctor before adding this — don't use it on your own.

Start the conversation before you begin.

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 supplement help my bones?
The evidence suggests vitamin K may help with osteoporosis, though the research is still coming in. If bone health is your goal, that's a reasonable reason to consider it — just clear it with your pharmacist or doctor first, especially if you're on any medications.

Why can't I just take this if I'm on warfarin?
Vitamin K can interfere with how warfarin works — it may make the blood thinner less effective at preventing clots. Your doctor may need to adjust your warfarin dose if you're taking vitamin K, so you need their input before starting.
