Vitamin K2: What It Does, Food Sources, and Supplement Basics
Quick overview
A practical guide to vitamin K2, food sources, supplement labels, and why medicines can change supplement decisions.
What vitamin K2 is
Vitamin K2 refers to several menaquinone forms of vitamin K.
Food-first choices are a sensible starting point.
Food sources
K2 appears in some fermented foods, cheeses and animal foods.
Diet patterns matter more than chasing one single nutrient.
Supplements and medicines
Supplement labels may list MK-4 or MK-7.
People using medicines affected by vitamin K should discuss supplements with a clinician.
A practical approach
Use supplements only when there is a clear reason.
More is not automatically better.
