How it works
1 study reviewed
In plain English

Vitamin K2 supplementation increases the activation of matrix Gla protein in rats with and without chronic kidney disease.

See the scientific wording

Vitamin K2 supplementation increases matrix Gla protein carboxylation in both healthy rats and rats with chronic kidney disease, suggesting it can restore a key vascular protective mechanism even in the presence of kidney dysfunction.

Why this might work

Vitamin K2 is taken up by blood vessel cells and used to activate an enzyme that adds a chemical group to a protein called matrix Gla protein. This activated protein binds to calcium in the vessel walls and stops it from forming hard deposits. Without this activation, calcium builds up and causes stiffening and damage to blood vessels.

  1. Study: Vitamin K antagonism aggravates chronic kidney disease-induced neointimal hyperplasia and calcification in arterialized veins: role of vitamin K treatment?

    Giving vitamin K2 helped activate a natural 'shield' protein in rats' blood vessels, even when their kidneys were damaged — meaning the body still listens to vitamin K2 even with kidney disease.
