The Claim
Vitamin K antagonism is associated with increased neointimal hyperplasia and vascular calcification in arterialized veins of rats with chronic kidney disease and in human dialysis patients, due to impaired carboxylation of matrix Gla protein.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Inhibition of vitamin K activity is linked to excessive tissue growth and calcium buildup in blood vessels of rats with kidney disease and in humans undergoing dialysis, resulting from reduced activation of matrix Gla protein.
See the scientific wording
Vitamin K antagonism is associated with increased neointimal hyperplasia and vascular calcification in arterialized veins of rats with chronic kidney disease, as well as in human dialysis patients, likely due to impaired carboxylation of matrix Gla protein, a key inhibitor of vascular calcification.
When vitamin K is blocked, a protein that normally stops calcium from building up in blood vessels cannot work. Without this protection, calcium deposits form in the vessel walls, which triggers cells in the vessel to multiply and thicken the inner lining, narrowing the blood vessel.
What the research says
1 studyBlocking vitamin K makes blood vessels more likely to harden with calcium because it stops a natural shield protein from working. Giving vitamin K2 helps fix this shield and reduces calcium buildup, proving the link.
