Vitamin K supplements:
what actually matters
This page is based on 1 vitamin k supplements that passed indexable quality thresholds inside SuppScoreLab. The average scientific score across the cluster is 6.1/10.
Not all vitamin k forms are equal
Instead of treating all vitamin k products as interchangeable, SuppScoreLab can compare how the market behaves by declared form. That is where the gap between better and weaker products becomes visible.
Form not declared
These products do not clearly declare the chemical form.
The strongest immediate signal is transparency. Products with no declared vitamin k form score materially lower on average than the leading declared forms in this cluster. That does not automatically make every undeclared product poor, but it does make independent evaluation weaker and reduces confidence in formulation quality.
