ADK (60 Capsules)
About this product

Doctor-formulated daily capsule combining Vitamins A (as Retinyl Palmitate), D3 (as Cholecalciferol), and K2 (as MK-7) from DaVinci Laboratories, designed to support bone, heart, and immune health. Vegetarian, gluten-free, and soy-free, with a minimal excipient profile and no fillers. Intended for use under the guidance of a healthcare practitioner; individuals taking this product should have serum Vitamin D levels monitored.

How it works
Vitamin A, as Retinyl Palmitate, helps maintain the health and function of mucosal membranes to promote a balanced immune response. Vitamin D3, as Cholecalciferol, supports the absorption and use of calcium by the body to help fortify bone health and support bone renewal and mineralization. Vitamin K2, as MK-7 (menaquinone-7), activates osteocalcin, a critical protein that helps guide calcium into bone rather than arteries, supporting both skeletal integrity and heart health. Together, the three vitamins address bone, cardiovascular, and immune function in a single daily capsule.
