Vitamin K2 Supplements

Vitamin K is an important nutrient, but there are actually two distinctly different forms of vitamin K: vitamin K1 and vitamin K2. K2 is also known as menaquinone. 

It is an important fat-soluble vitamin that supports healthy blood circulation, bone health, bone density, immune system function, and heart health. Vitamin K2 also supports how vitamin D is stored in the body.^†

Both forms of vitamin K are available from dietary sources. Phylloquinone, or vitamin K1, is mostly found in leafy green vegetables. K2 is found in animal sourced foods like butter, cheese, meat, egg yolks, and natto.
