The synergistic combination found in Vitamin A, D3 & K2 Capsules helps to support bone structure, density, and integrity, proper bone remodeling, calcium utilization, and cardiovascular function. Vitamin A is required for normal development, growth and maintenance of the skeleton throughout life. Vitamin D3 is essential for maintaining normal calcium metabolism. It supports calcium absorption in the gut. Vitamin K2, known as menaquinone is the form that has been shown to support normal bone formation. When Vitamin K2 is deficient or not well used in our bodies, bone structure and function can be compromised.
