Buying Guide

Choose the right vitamin K form

MK-4 and MK-7 have different half-lives and tissue targets, so pick a product that contains the form(s) aligned with your health goals

Check dosage per serving

Compare micrograms or milligrams per serving to ensure the product delivers an effective dose for bone or cardiovascular support

Consider combined nutrients

Formulas that include vitamin D3, calcium cofactors, zinc, or vitamin C can support absorption and complementary pathways

Select the right delivery format

Softgels, capsules, and liquid drops offer different absorption profiles and dose flexibility—choose based on convenience and tolerance

Review purity and labeling

Look for transparent ingredient lists, explicit MK-4 vs MK-7 labeling, and third-party testing or manufacturing disclosures when available
