Buying Guide

Choose the right K form

K1 supports liver-related clotting functions while K2 (MK-4 and MK-7) is linked to bone and arterial calcium metabolism; select formulas that list which forms and amounts are included

Check standardized dosages

Look for supplements that state microgram or milligram amounts per serving so you can compare potency—some products provide high-dose MK-4 while others emphasize MK-7 for longer circulation

Look for complementary nutrients

Vitamin D, calcium-regulating cofactors, zinc, or vitamin C are often paired with K to support bone and cardiovascular function; evaluate combos based on your health needs

Consider delivery format and bioavailability

Softgels, capsules, and emulsions can affect absorption—lipid-soluble K2 generally benefits from oil-based softgels or liquid emulsions for better uptake

Assess brand transparency and labeling

Prefer products that disclose MK-4 vs MK-7 content, provide clear serving sizes, and note vegan or vegetarian status if that matters to you
