Natecal D3 (Colecalciferol, Calcium Carbonate)

Colecalciferol is converted in the liver to 25‑hydroxyvitamin D and then in the kidney to the active hormone calcitriol. Calcitriol binds to vitamin D receptors, increasing transcription of calcium‑binding proteins and enhancing intestinal absorption of calcium and phosphate, which are essential for bone mineralization.

The specific dose of Natecal D3 is determined by the prescribing healthcare professional based on the individual’s age, nutritional status, laboratory values and clinical needs. Patients should follow the prescriber’s instructions and not exceed the recommended amount.

Safety in pregnancy and lactation has not been fully established; therefore, use should be discussed with a qualified healthcare provider. The prescriber will weigh potential benefits against any theoretical risks before recommending the supplement.

GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any required import documentation.

Natecal D3 combines both colecalciferol and calcium carbonate in a single oral formulation, whereas many alternatives provide only vitamin D or calcium alone. This dual composition may simplify dosing for patients needing both nutrients, but clinicians should compare potency, elemental calcium content and regulatory status when selecting a product.

Natecal D3 should be stored at ambient temperature, below 25 °C, in its original packaging. Keep the container tightly closed, protect it from moisture, direct sunlight and excessive heat to maintain product stability throughout its shelf life.

The product is taken orally, usually with food or a glass of water, as directed by the prescribing clinician. Swallow tablets or capsules whole; do not crush or chew unless the formulation specifically allows it.

The most serious adverse reactions include hypercalcemia, which may present with nausea, vomiting, weakness, and cardiac arrhythmias, and rare allergic responses such as rash, itching or swelling. Patients experiencing these symptoms should seek medical attention promptly.

Individuals with known hypersensitivity to colecalciferol, calcium carbonate or any excipients, as well as patients with severe hypercalcemia, hypervitaminosis D, or certain renal disorders, should avoid using this supplement unless a healthcare professional advises otherwise.
