Vitamin D3/K2 compared
The reference figure is cholecalciferol (vitamin D3) per serving. Label values given in International Units are converted to mass.
Documented batch measurements first, then linked lab reports and sourced declarations. Reports with measurements outside a stated criterion rank last. Equal evidence is ordered by serving price. This ranks documentation, not health effects.
