dr. mercola, vitamins d3 & k2, 30 capsules

Researchers are discovering that Vitamin D may be the most important nutrient ever discovered for supporting immune health. Regulating the expression of more than 900 genes in your body, vitamin D3 influences just about every function, including healthy cell development and growth, strong bones, cardiovascular health, brain health and cognition. However, supplementing with just vitamin D isn’t enough. When you take vitamin D, it is vitally important to also get enough vitamin K2. Not only do the two vitamins work synergistically, vitamin D needs vitamin K2 to function properly. Taken together, vitamins D3 and K2 support your overall heart health, arteries and veins, bone health, and respiratory and immune systems.
