Maxi-Kalz Vit. D3 (Colecalciferol, Calcium)

Colecalciferol is 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 in the intestine, stimulating the synthesis of calcium‑binding proteins and thereby increasing calcium and phosphate absorption, which are essential for bone mineralization and calcium homeostasis.

The appropriate dose of Maxi‑Kalz Vit. D3 is determined by the prescribing healthcare professional based on the patient’s age, nutritional status, laboratory results and clinical needs. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Calcium and vitamin D are essential nutrients during pregnancy and lactation, but the safety of Maxi‑Kalz Vit. D3 in these populations should be evaluated by a qualified healthcare provider. The prescriber will consider maternal and fetal needs before recommending the product.

Maxi‑Kalz Vit. D3 combines calcium with colecalciferol in a single oral tablet, offering a convenient source of both nutrients. Compared with separate calcium or vitamin D supplements, it simplifies dosing and may improve adherence, while the elemental calcium and vitamin D content are comparable to other standard formulations.

Store Maxi‑Kalz Vit. D3 at ambient temperature, preferably below 25 °C. Keep the tablets in the original container, protect them from moisture, excessive heat and direct sunlight. Do not store in the refrigerator or freezer unless otherwise indicated on the packaging.

Maxi‑Kalz Vit. D3 is taken orally, usually with a glass of water. It can be taken with or without food, but some patients prefer taking it with meals to reduce possible gastrointestinal discomfort. Follow the dosage instructions provided by the prescribing clinician.

The most serious risks associated with calcium and vitamin D supplementation include hypercalcemia, which may present with nausea, vomiting, weakness, or cardiac arrhythmias, and the formation of kidney stones. If any of these symptoms occur, medical attention should be sought promptly and the product discontinued.

Individuals with known hypersensitivity to calcium, colecalciferol or any excipients in the tablet should avoid the product. Patients with severe renal impairment, hyperparathyroidism, sarcoidosis, or active hypercalcemia should not use it without medical supervision, as the supplement may exacerbate these conditions.
