Bone health, calcium balance, muscle and nerve function, antioxidant support
Adults with low dairy or calcium intake and people who spend most of their time indoors or have limited sun exposure.
Take 3 tablets daily with food; taking with a meal may enhance calcium and vitamin D3 absorption and improve tolerance.
Formulated without: Gluten, GMOs, or Soy. Not manufactured with milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soy, sesame, or gluten. Produced in an FDA-registered, third-party audited, cGMP-compliant facility that may process other products containing these allergens.
Calcium provides the building blocks for bones and teeth and is involved in muscle contraction and nerve signaling.
Caution: Take with food to support absorption and reduce stomach upset; separate from high-dose iron or zinc to avoid absorption competition.
Vitamin D3 supports calcium absorption in the gut and helps regulate calcium balance for bone mineralization.
Caution: Avoid excessive total vitamin D intake from multiple sources to reduce the risk of elevated calcium levels.
Vitamin K2 activates proteins like osteocalcin that help direct calcium into bones and away from soft tissues.
Caution: People using blood-thinning medications should consult a healthcare professional because vitamin K can affect clotting pathways.
Magnesium is a cofactor for enzymes involved in bone formation and helps regulate calcium transport and muscle and nerve function.
Caution: May cause loose stools in some people; consider splitting the dose with meals if sensitive.
Citrus bioflavonoids act as plant antioxidants that may help protect cells from oxidative stress.
Caution: Those sensitive to citrus should monitor for digestive discomfort.
Calcium supplies the core mineral for bone structure, while vitamin D3 enhances calcium absorption. Vitamin K2 helps guide absorbed calcium into bones, and magnesium supports bone enzyme activity and calcium regulation. Citrus bioflavonoids add antioxidant support for overall cellular health.
Label Warning: Consult a qualified healthcare professional before use. Accidental overdose of iron-containing products can be fatal in children under 6; keep out of reach of children and seek medical help or contact a poison control center immediately if overdose occurs.
Who should be cautious: People taking anticoagulants such as warfarin may need caution due to vitamin K2 content. Those on thyroid medications or certain antibiotics may need to separate dosing from calcium and magnesium to avoid reduced absorption. If you use medications that may interact with vitamin K, calcium, magnesium, or iron, discuss with a healthcare provider before use.
Storage: Store in a cool, dry place. Protect from heat, light, and moisture.
