Oleovit D3 (Colecalciferol)

Colecalciferol is first converted in the liver to 25‑hydroxyvitamin D and then in the kidney to the active hormone 1,25‑dihydroxyvitamin D. This active form binds to vitamin D receptors, increasing intestinal absorption of calcium and phosphate, which are essential for bone health and calcium balance.

The appropriate dose of Oleovit D3 is determined by the prescribing clinician based on the patient’s serum vitamin D level, age, weight, and clinical condition. Dosage may vary widely, and patients should follow the specific instructions provided by their healthcare provider.

Oleovit D3 may be used during pregnancy or lactation only if the prescriber deems it necessary. Vitamin D is important for fetal bone development, but the decision should be individualized, and the lowest effective dose should be selected to avoid excess calcium.

To order Oleovit D3, submit an enquiry on the product page at gnhindia.com with the required quantity.

Oleovit D3 provides colecalciferol, the same active ingredient found in many vitamin D supplements. Compared with ergocalciferol (vitamin D2), colecalciferol generally has a longer half‑life and may achieve more stable serum levels, making it a preferred choice for many clinicians.

Oleovit D3 should be stored at room temperature, below 25 °C, in its original packaging. Keep the container tightly closed, protect it from moisture and direct sunlight, and discard any product that appears discolored or compromised.

Oleovit D3 is taken orally, usually with water. It can be taken with or without food, but consistent administration with respect to meals helps maintain stable absorption. Patients should follow the dosing schedule prescribed by their healthcare professional.

The most serious risks include severe hypercalcemia, which can cause cardiac arrhythmias, renal stones, and kidney damage. Rarely, allergic reactions such as rash, swelling, or anaphylaxis may occur. Patients should seek immediate medical attention if they experience symptoms of high calcium or an allergic response.

Oleovit D3 should be avoided in individuals with known hypersensitivity to colecalciferol or any excipients, those with untreated hypercalcemia, and patients with severe renal impairment unless specifically directed by a physician. Pregnant or nursing women should only use it under medical supervision.
