Vitamin K2 is essential to the body as it helps to dissolve the calcium remnants located in the arteries, leading them to the bones of the body, thus avoiding osteoporosis and decreasing the risks of heart disease. According to research I have done, I am using the same in conjunction with magnesium and vitamin D3 and I also use omega 3 capsules. Vitamin D is a fat-soluble vitamin, ie it should be ingested with a food that has fat to potentiate its effects. So I like to eat after breakfast or lunch. In the other, I recommend the purchase to all !!!
