K2

Vitamin K2 is a fat-soluble vitamin that plays a fundamental role in calcium regulation, absorption, and bone health. 

Overall, Vitamin K2 promotes proper calcium handling throughout the body, prevents excessive calcium buildup in the vascular system, and supports overall immunity. 

Vitamin K2 activates matrix GLA protein, a protein found in the tissues of the heart, kidneys, and lungs that plays a dominant role in vascular calcium metabolism. Matrix GLA protein production is stimulated by Vitamin D3, but it requires adequate Vitamin K2 intake to be activated. Once activated by Vitamin K2, matrix GLA protein can bind calcium and escort it out of the areas where it is deleterious, like the cardiovascular system and soft tissues.

Supplemental Vitamin K2 exists in several forms, but the most common ones are the synthetic menaquinone-4 (MK-4) and the natural menaquinone-7 (MK-7). 

Studies consistently show that Vitamin K2 as MK-7 is much more effective compared to MK-4. HD Muscle K2 is formulated using patented MenaQ7 vitamin K2. Each capsule contains 160 mcg of Vitamin K2 as MenaQ7. MenaQ7 is the only clinically proven form of vitamin K2 and studies show it has the highest absorption, half-life, and bioavailabilty over other forms. Take as directed.
