Vitamin D regulates calcium and phosphate biology and contributes to immune and muscle function.

Vitamin K2 evidence for bone and cardiovascular endpoints is still evolving. The combination should be marketed around established nutrient functions, not as a proven anti-calcification or longevity intervention.\u003c\/p\u003e\u003cp\u003eWHO IT IS FOR\u003cbr\u003eAdults with limited sun exposure or an identified need for vitamin D support, excluding people using vitamin K antagonists without clinician approval.\u003c\/p\u003e\u003cp\u003eHOW TO USE\u003cbr\u003eAdults take one capsule daily with a meal containing fat.
