Bone health, calcium utilization, cardiovascular support
Adults with limited sun exposure or low dietary intake of K2-rich fermented foods seeking daily bone and cardiovascular nutrient support.
Take 1 tablet daily, preferably with a meal; fat-containing meals may support vitamin D3 absorption.
Non-GMO. Contains: Soy. Contains no yeast, dairy, egg, gluten, or wheat. No preservatives, or artificial color, flavor, or fragrance.
Vitamin D3 is converted to calcitriol, which supports calcium absorption in the gut and helps regulate calcium balance for bones and other tissues.
Caution: Take with food to support absorption; excessive total vitamin D from multiple products may raise calcium levels.
Vitamin K2 (MK-7) activates calcium-regulating proteins like osteocalcin and matrix Gla protein that help direct calcium to bones and away from soft tissues.
Caution: Consult a healthcare professional if using blood-thinning medications because vitamin K can affect anticoagulation.
Calcium provides a structural mineral for bones and participates in muscle contraction and nerve signaling.
Caution: Space calcium away from certain minerals or medications when possible because it can interfere with their absorption.
Vitamin D3 supports intestinal calcium absorption, while vitamin K2 activates proteins that guide calcium to bones and away from soft tissues. The added calcium supplies a direct mineral source that complements D3 and K2’s roles in calcium utilization.
Label Warning: If you are pregnant, may become pregnant, breastfeeding, or taking anticoagulant drugs such as warfarin, consult a healthcare practitioner before use. Vitamin K2 may counteract anticoagulation therapy and is not recommended for those on blood-thinning medications.
Who should be cautious: People with soy allergies should avoid this product. Those on anticoagulants like warfarin may have interactions with vitamin K and should discuss with a healthcare provider before use. People taking anticoagulants are recommended to consult with a healthcare provider before combining with medications that may cause interaction.
Many users feel the combo supports bone strength and heart wellness in a convenient daily dose.
