The Claim
The absence of an effect of vitamin K2 on vascular stiffness in chronic kidney disease does not imply that other forms of vitamin K, different dosages, longer durations, or different patient populations lack potential effects on vascular stiffness.
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.
Vitamin K2 does not reduce vascular stiffness in people with chronic kidney disease, but this does not mean other types of vitamin K, higher doses, longer use, or different patient groups also have no effect.
See the scientific wording
The lack of effect of vitamin K2 on vascular stiffness in chronic kidney disease does not rule out potential benefits from other forms of vitamin K, different dosages, longer durations, or different patient populations.
Vitamin K activates a protein that stops calcium from building up in blood vessel walls; if this protein is not activated, calcium deposits harden the arteries.
What the research says
1 studyJust because one type of vitamin K didn't help stiff arteries in kidney patients doesn't mean other kinds, higher doses, or different people won't benefit — the study itself says other approaches might still work.
