What should I know about d3 k2 vitamin dosierung wirkung und kombination?

Vitamin D3 and K2 work synergistically: D3 enhances calcium absorption in the gut, while K2 (especially MK-7) activates proteins that direct calcium into bones and teeth and prevent arterial calcification. Optimal dosage depends on individual status – typical recommendations are 1000–2000 IU D3 and 45–100 µg K2 (MK-7) daily. A blood test (e.g., VitalCheck Basic) can measure D3 levels; K2 is usually not directly tested. The combination is plausible, but evidence for a fixed joint dosage is moderate – many studies are observational. Caution with blood thinners (vitamin K antagonists): K2 may interfere. MyBody-X offers nutrient tests, but these do not replace medical advice. Consult a doctor before supplementing if you have health conditions or take medication.
