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 at 45 micrograms per serving. The liquid also includes medium chain triglyceride oil and an antioxidant blend as inactive ingredients to stabilize and deliver the vitamin.

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 system health.
  • We looked for evidence on: Cardiovascular disease (CVD), Osteoporosis, Warfarin anticoagulation, Vascular calcification, Bone mineralization.
  • The strongest evidence on file: Vitamin K is rated "Effective" for Warfarin anticoagulation (Natural Medicines).
  • Also on file: Vitamin K is rated "Possibly Effective" for Osteoporosis.
  • Also on file: Vitamin K is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD).

Vitamin K2 is effective for correcting vitamin K deficiency and supporting the vitamin K-dependent clotting factors your body needs for normal blood clotting. It's also possibly effective for osteoporosis, though the evidence for that use isn't as established.

The evidence, ingredient by ingredient Vitamin K

How safe is it?

Well-documented data
Safety Information · database check

  • 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.

  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
