The Claim
In adults with chronic kidney disease stages 3b or 4, vitamin K2 supplementation over a 12-month period has no effect on blood markers of mineral metabolism or vascular health, including B-type natriuretic peptide.
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 K2 supplements for 12 months does not change levels of blood markers related to mineral balance or heart health in adults with moderate to severe chronic kidney disease.
See the scientific wording
In adults with chronic kidney disease stages 3b or 4, vitamin K2 supplementation does not alter blood markers of mineral metabolism or vascular health, including B-type natriuretic peptide, over a 12-month period.
In advanced kidney disease, the blood contains too much calcium and phosphate, which build up in blood vessel walls. Vitamin K2 normally helps activate a protein that stops this buildup, but in this condition, the protein cannot be activated because the kidneys cannot process the vitamin properly, so the calcium and phosphate keep accumulating without change.
What the research says
1 studyThis study gave people with advanced kidney disease vitamin K2 pills for a year and found no change in their heart or mineral blood markers compared to those who took a placebo. So, the vitamin didn’t help or hurt these measures.
