Buying Guide

Choose the right K form

MK-4 and MK-7 have different absorption and tissue targets; look for formulas that specify which menaquinone is included to match your health goals

Check combined nutrients

Products that pair vitamin K with vitamin D3, zinc, or vitamin C can support bone and cardiovascular pathways more effectively than isolated K alone

Dose and serving economics

Compare microgram or milligram amounts per serving and total servings per bottle to assess value rather than relying on price alone

Formulation & delivery

Consider softgels, capsules, or liquid drops based on ease of swallowing and whether the product is vegan or uses carrier oils that affect absorption

Third-party info & ratings

Prioritize brands with clear labeling, consistent star ratings, and accessible ingredient lists to verify purity and manufacturing standards
