Buying Guide

Choose K2 form based on longevity

MK‑7 stays in circulation longer than MK‑4 and may be preferable for once‑daily dosing; check product labels for which menaquinone forms are included

Match delivery form to absorption needs

Softgels and emulsified liquid drops can aid absorption of fat‑soluble vitamin K, while tablets may be less bioavailable without a meal containing fat

Consider combination nutrients

Products that pair vitamin K with vitamin D, calcium, zinc, or vitamin C can support bone and cardiovascular pathways but evaluate total nutrient amounts to avoid excess

Check concentration per serving

Compare microgram levels and serving size—higher mcg per serving can mean fewer doses per day and clearer dosing guidance

Verify quality and transparency

Look for clear labeling of menaquinone types (MK‑4, MK‑7), third‑party testing, and allergen or vegan status to match dietary preferences
