Cholecalciferol is converted to calcitriol, which supports calcium and phosphate absorption in the gut and helps regulate bone mineralisation and immune cell activity.
Caution: Avoid excessive total vitamin D intake from multiple products, as too much may raise blood calcium levels; take with food for better absorption.
MK-4 activates vitamin K-dependent proteins such as osteocalcin and matrix Gla protein, which help direct calcium into bone and away from soft tissues.
Caution: If you use blood-thinning medicines, consult a healthcare professional because vitamin K can affect how these medicines work; keep intake consistent day to day.
Vitamin D3 supports calcium absorption, while vitamin K2 activates proteins that guide calcium into bone and away from arteries. Together they address both uptake and placement of calcium for balanced skeletal and vascular support.
Label Warning: For adult use only. Consult a healthcare professional before use if you are pregnant or nursing, have a medical condition, or use prescription medicines.
Who should be cautious: People taking anticoagulants such as warfarin may need extra caution due to vitamin K2 content; discuss with a healthcare professional. Those using high-dose vitamin D or with high calcium levels may also wish to consult a healthcare professional. If you take interacting medications, it is recommended to speak with your healthcare provider before use.
