Vitamin K2
Usually taken alongside vitamin D for calcium handling
MK-7 is the form usually taken, alongside vitamin D, on the reasoning that this fat-soluble vitamin directs calcium to bone rather than arteries. Human outcome evidence is much weaker than the mechanistic story, so it stays a companion supplement rather than a headline one. Standing caution for anyone on blood thinners.
