The Claim
Vitamin K supplementation has no overall effect on vascular stiffness or vascular calcification measures in patients with chronic kidney disease.
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.
Taking vitamin K supplements does not change the stiffness or calcification of blood vessels in people with chronic kidney disease.
See the scientific wording
An updated meta-analysis combining the results of this trial with prior studies shows no overall effect of vitamin K supplementation on vascular stiffness or vascular calcification measures in patients with chronic kidney disease.
Vitamin K activates proteins that prevent calcium from building up in blood vessels, but in people with kidney disease, these proteins are already fully active or blocked by other factors, so adding more vitamin K does not change calcium deposits or artery stiffness.
What the research says
1 studyScientists gave vitamin K supplements to people with kidney disease for a year and found it didn’t help stiff arteries get better. When they added this result to all other similar studies, they still found no benefit.
