Buying Guide

Choose the right vitamin K form

K1 supports basic clotting functions while K2 (MK-4 and MK-7) is more commonly linked to bone and vascular health; check labels for the specific menaquinone form you need

Check dose per serving

Compare microgram or milligram amounts so you can match clinical recommendations or your clinician's advice—some products provide concentrated MK-4 or combined K1/K2 blends

Consider delivery format

Softgels, capsules, and liquid drops affect dosing flexibility and absorption; liquid drops like emulsion forms may be easier for precise low-dose titration

Look for added nutrients

Formulations that pair vitamin K with vitamin D3, zinc, or vitamin C can support bone and immune functions, but review total nutrient amounts to avoid duplication with other supplements

Review quality signals

Prioritize brands with transparent ingredient lists, standardized menaquinone naming (MK-4, MK-7), and consistent high ratings and review counts from users
