Bone health; Calcium absorption support
Adults with low dairy or calcium intake and people who spend limited time outdoors seeking simple daily bone mineral support.
Adults take 1 tablet with a meal, twice daily; taking with food and a full glass of water may improve tolerance and ease swallowing. Tablets may be broken in half. Can be taken with a multivitamin.
Gluten Free. Contains: Shellfish (oyster). No added yeast or artificial flavors.
Calcium provides the mineral building blocks for bones and teeth and supports normal muscle contraction and nerve signaling.
Caution: Take with food and water to reduce stomach upset; high intakes may contribute to constipation or interfere with absorption of iron and certain medications.
Vitamin D3 helps the intestines absorb calcium and supports proper calcium balance for bone mineralization.
Caution: Avoid combining with high-dose vitamin D from other supplements unless advised, as excessive intake may raise blood calcium levels.
Vitamin D3 supports intestinal absorption of calcium, helping more of the mineral reach the bloodstream. Adequate vitamin D3 also helps regulate calcium balance, which complements calcium’s structural role in bones.
Label Warning: Consult a healthcare provider before use if you are pregnant, nursing, taking medications, have a medical condition, or are planning a medical procedure. Stop use and contact a physician if adverse reactions occur.
Who should be cautious: People with shellfish allergies should avoid this product due to oyster shell calcium. Those with a history of kidney stones, high calcium levels, or on thyroid medications or certain antibiotics may need to separate dosing from calcium. People taking blood pressure medicines that are calcium channel blockers should discuss use with a healthcare provider. If combining with medications that may interact with calcium, consult a healthcare provider before use.
Storage: Store at room temperature.
