A K2 deficiency leads to weak bones and teeth and clogged arteries. K2 has an influential role in the utilization of minerals, protection from tooth decay, growth and development, reproduction, protection against heart disease and the function of the brain. Vitamin K2 is produced by animal tissues, including the mammary glands and rapidly growing green plants.
K2 protects against calcification of the arteries leading to heart disease, and is a major component of the brain.
K2 works synergistically with vitamins A and D. Vitamins A and D signal to the cells to produce certain proteins and vitamin K then activates these proteins.
