The Claim

In hemodialysis patients, vitamin K2 supplementation at 360 μg three times weekly for 18 months is not associated with an increased risk of adverse events, vascular access complications, or thrombosis.

In plain English

In patients undergoing hemodialysis, taking vitamin K2 at 360 micrograms three times per week for 18 months does not increase the occurrence of adverse events, complications with vascular access, or blood clots.

See the scientific wording

In hemodialysis patients, vitamin K2 supplementation at 360 μg three times weekly for 18 months is not associated with increased risk of adverse events, vascular access complications, or thrombosis, despite concerns about its role in coagulation pathways.

Why this might work

Vitamin K2 activates a protein in blood vessel walls that stops calcium from building up in the wrong places; this process does not interfere with blood clotting or the function of dialysis access sites.
