Bone health, calcium utilisation, cardiovascular calcium balance
Adults with limited sun exposure or low dietary intake of vitamin K–rich fermented foods seeking daily bone mineral support.
Take 1 tablet daily with a meal; fat-containing foods may help absorption of vitamin D3.
Non-GMO. Contains: Soy. No yeast, dairy, egg, gluten, soy, or wheat. No preservatives, artificial colour, flavour, or fragrance.
Vitamin D3 is converted to its active form, which supports calcium and phosphorus absorption in the gut and helps regulate bone mineralisation.
Caution: May raise calcium levels; take with food for better absorption and avoid combining with very high-dose calcium unless advised.
MK-7 activates vitamin K–dependent proteins such as osteocalcin and matrix Gla protein, which help direct calcium into bones and away from soft tissues.
Caution: May interact with blood-thinning medicines like warfarin because it affects clotting pathways; seek professional guidance if using anticoagulants.
Calcium provides a structural mineral for bones and teeth and participates in muscle contraction and nerve signalling.
Caution: Space away from certain minerals or high-fibre supplements that may reduce absorption; do not exceed overall daily calcium needs from all sources.
Vitamin D3 supports intestinal absorption of calcium, increasing its availability. Vitamin K2 activates proteins that help deposit circulating calcium into bone and limit deposition in soft tissues. The modest calcium included supplies a foundational mineral that complements the vitamin-driven utilisation process.
Label Warning: If you are pregnant, planning pregnancy, breastfeeding, or taking anticoagulant medicines such as warfarin, speak with a healthcare professional before use. Vitamin K2 may counteract anticoagulation therapy and is not recommended for those on blood-thinning medicines.
Who should be cautious: People with soya allergy should avoid due to soya content. Those on anticoagulants should be especially cautious because vitamin K may affect anticoagulation. People taking high-dose vitamin D from other sources should monitor total intake. As this product contains vitamin K, if you use anticoagulant medicines, consult a healthcare provider before combining.
