Bone health, calcium absorption
Adults with low dietary calcium intake or limited sun exposure seeking everyday bone and mineral support.
Take 3 tablets daily with a meal or a glass of water; taking with food may enhance comfort and vitamin D absorption.
Gluten-free
Calcium provides the mineral building blocks for bones and teeth and supports muscle contraction and nerve signalling.
Caution: Take with food or water to reduce stomach upset; separate from high‑iron or high‑zinc supplements by a few hours as minerals can compete for absorption.
Vitamin D increases intestinal absorption of calcium and phosphorus, supporting normal calcium balance for bone mineralisation.
Caution: Avoid combining with high‑dose vitamin D from other products to limit excessive intake, and consider taking with a meal containing fat for better absorption.
Vitamin D supports intestinal uptake of calcium and helps the body utilise calcium effectively, while calcium supplies the structural mineral needed for bones and teeth. Together they address both absorption and availability to support daily mineral needs.
Label Warning: Do not use if the safety seal is broken or missing. Keep out of reach of children. Keep your registered health care practitioner informed when using this product.
Who should be cautious: People taking tetracycline or fluoroquinolone antibiotics, or thyroid medications, as calcium may reduce absorption; consider separating doses by at least 2 hours. Those with a history of kidney stones or high calcium levels may need medical guidance. Individuals on high-dose vitamin D regimens should monitor total intake from all sources.
Storage: Store in a cool, dry place.
