Good for Your Heart and Your Bones
DO NOT take vitamin D3 without the MK-7 version of vitamin K2. D3 causes calcium to be absorbed into your small intestines. Without K2 that calcium will calcify your arteries causing a heart attack. With K-2 the calcium will be driven into your bones where it belongs. Do not use the MK-4 version. A study found zero difference between the blood levels of people who took MK-4 and people who took none. In other words MK-4 is useless. Only MK-7 is bioactive.
