What Does Vitamin K+D Do?
This Natural Factors formula supplies 120 mcg Vitamin K2 as MK-7 from natto and 1000 IU Vitamin D3 as cholecalciferol per serving. Evidence from reviews supports their synergy for directing calcium to bones rather than arteries, with moderate trial data for improved bone density and reduced vascular calcification at comparable doses.
How does the 120 mcg Vitamin K2 (MK-7) dose compare to amounts used in bone density studies?
What is the evidence for combining 1000 IU Vitamin D3 with MK-7 for cardiovascular health?
Are there any specific populations that should avoid this Vitamin K2 and D3 combination?
