From our pharmacy team — supplement deep dive

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product has 2 active ingredients: MenaQ7, a form of vitamin K, and VegD3, a plant-based vitamin D3. The drops are suspended in sunflower oil and medium-chain triglyceride (an inactive carrier oil to help absorption).

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 D3 and K2 nutrient supplementation.
  • We looked for evidence on: Hemorrhagic disease, Hypoprothrombinemia, Intraventricular hemorrhage, 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.

MenaQ7 (vitamin K) is effective for treating vitamin K deficiency conditions and supporting blood clotting factors. It's also possibly effective for osteoporosis.

We don't have effectiveness data on file for VegD3 in this product.

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.

Vitamin K by mouth is generally well tolerated. The most common side effects are mild stomach upset, nausea, diarrhea, and abdominal pain — usually mild to moderate.

Vitamin K is rated likely safe in pregnancy and during breastfeeding. Normal dietary amounts are fine, but before you take supplements, check with your doctor, especially if you're on any medications.

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 any blood thinner, check with your pharmacist before starting this product — vitamin K can reduce its effectiveness. We couldn't check the VegD3 ingredient, so mention all your prescriptions when you ask.
