The Platinum Standard for Vitamin K Complex Supplements The Calcium Traffic Cop Recent clinical studies have shown that Vitamin K2 acts as a traffic cop when it comes to directing calcium where it needs to go to make sure it does its critical work - strengthening your bones and teeth. Why is Vitamin K2 Important? Vitamin K2 is virtually absent in our modern day diets. K2 deficiencies occur in as little as a week when your diet is low on K2 rich foods . . . and the result is calcium starts accumulating in the soft tissues and arteries and is not getting to the bone, where it's desperately needed. Do I need More Than One Form of Vitamin K Yes . . . That's because Vitamin MK-7 and MK-4 serve different vital functions necessary for your good health. - MK-4 is found in the brain and plays a significant role in supporting normal brain functions. - MK-7 is a bioactive form of K2 found naturally occurring in Natto and causes the carboxylation of specific bone proteins required for building strong bones. Recent studies also indicate MK-7 promotes cardiovascular health.
