Ingredients explained
Vitamin D3 (cholecalciferol)
Vitamin D3 is converted to its active form that supports calcium and phosphorus absorption and influences immune cell signaling.
Caution: Avoid excessive total vitamin D intake from multiple products because very high levels may raise blood calcium.
Vitamin K2 (MK-4, menatetrenone)
Vitamin K2 activates proteins like osteocalcin and Matrix Gla Protein that help direct calcium into bones and away from soft tissues.
Caution: Consult a healthcare professional if you use blood-thinning medications because vitamin K can affect how they work.
How they work together
Vitamin D3 supports calcium absorption from the gut, while vitamin K2 activates proteins that guide calcium into bone tissue. Together they address both uptake and placement of calcium for efficient mineral use.
Safety and tips
Label Warning: If pregnant, consult your health-care practitioner before use.
Who should be cautious: People taking anticoagulants such as warfarin may need to be cautious with vitamin K2. Those using high-dose vitamin D alongside calcium should monitor total intake. Consult a healthcare provider before combining with anticoagulants.
Storage: Store tightly sealed in a cool, dry place. Do not refrigerate.
