Ingredients explained
Vitamin D3 (cholecalciferol)
Vitamin D3 is converted to calcitriol, which regulates calcium and phosphorus absorption and supports normal bone mineralization and muscle function.
Caution: High-potency vitamin D may raise blood calcium; consult a professional if you take high-dose calcium or have kidney concerns.
Vitamin K2 (menaquinone-4 and menaquinone-7)
Vitamin K2 activates matrix Gla protein and osteocalcin, directing calcium into bones and away from soft tissues.
Caution: Vitamin K can interact with anticoagulant medications like warfarin; speak with a professional before use if you use blood thinners.
Vitamin K1 (phylloquinone)
Vitamin K1 serves as a cofactor for enzymes that enable vitamin K–dependent proteins to bind calcium for normal clotting and bone-related functions.
Caution: May affect blood-thinning therapy; consistent intake and professional guidance are important if you use anticoagulants.
Vitamin A (retinyl palmitate)
Vitamin A supports the formation of visual pigments and regulates gene expression involved in epithelial tissue integrity and immune function.
Caution: Excess preformed vitamin A can accumulate; avoid combining with other high-dose vitamin A products, especially during pregnancy.
How they work together
Vitamin D3 supports calcium absorption, while vitamins K1 and K2 activate proteins that guide calcium to bones and away from soft tissues. Vitamin A adds support for epithelial tissues and overall nutrient balance in a fat-soluble vitamin complex.
