Bone health, calcium utilisation, cardiovascular wellness
Adults with limited dietary intake of vitamin K-rich foods or those seeking bone and vascular calcium balance support in daily wellness routines.

MK-4 activates vitamin K-dependent proteins such as osteocalcin and matrix Gla protein, which may help direct calcium into bones and away from soft tissues.
Caution: Those using anticoagulant medicines should seek medical guidance because vitamin K can affect how these medicines work.
Vitamin K1 supports the carboxylation of vitamin K-dependent proteins involved in calcium handling and normal blood clotting.
Caution: If you use anticoagulant medicines, consult a professional as vitamin K1 intake can influence clotting measurements.
MK-7 provides a longer-lasting form of vitamin K that activates calcium-regulating proteins to support bone mineralisation and vascular calcium balance.
Caution: People on anticoagulant therapy should check with a professional because MK-7 can alter vitamin K status.
Vitamin D3 increases intestinal calcium absorption and supports the production of osteocalcin, aiding bone mineralisation.
Caution: Take with food containing fat for better absorption, and avoid combining with high-dose calcium without guidance if you are prone to high calcium levels.
Vitamin D3 supports calcium absorption and the production of osteocalcin, while the K vitamins activate osteocalcin and other Gla proteins so they can bind calcium effectively. MK-7 offers a longer half-life, complementing the faster-acting MK-4 and K1 to maintain activation of calcium-regulating proteins throughout the day.
Label Warning: Consult a healthcare professional before use if pregnant, nursing, under 18, taking medication (especially anticoagulants such as warfarin), or have a medical condition. Discontinue use if adverse reactions occur.
Who should be cautious: People on anticoagulants such as warfarin may need closer monitoring due to vitamin K content. Those with a history of high calcium or on high-dose vitamin D should use caution with the vitamin D3 amount. If combining with anticoagulants, discuss with a healthcare provider before use.
Storage: Store in a cool, dry place.
