Indications & Clinical Uses

Maxi‑Kalz Vit. D3 provides vitamin D3 and calcium to address conditions related to bone and mineral metabolism.

  • Calcium deficiency: helps restore normal calcium levels and supports bone mineralization.
  • Osteomalacia/Rickets: contributes to the correction of impaired bone mineralization in adults and children.
  • Osteoporosis prevention: supplies calcium and vitamin D to maintain bone density and reduce fracture risk.

How It Works

  • Colecalciferol (vitamin D3) is converted in the liver to 25‑hydroxyvitamin D and subsequently in the kidneys to the active hormone calcitriol, which binds to vitamin D receptors in intestinal cells, enhancing calcium and phosphate absorption. Calcium carbonate dissociates in the acidic stomach environment, releasing calcium ions that are absorbed in the small intestine, together supporting skeletal mineralization.

Side Effects

Maxi‑Kalz Vit. D3 is generally well tolerated, but some users may experience adverse reactions.

Common Side Effects

  • Nausea: mild gastrointestinal discomfort.
  • Constipation: reduced bowel movements.
  • Abdominal pain: intermittent stomach cramps.
  • Headache: mild to moderate intensity.
  • Dry mouth: reduced salivation.
  • Hypercalcemia (mild): elevated blood calcium levels without severe symptoms.

Serious or Rare Side Effects

  • Severe hypercalcemia: may cause cardiac arrhythmia, confusion, or kidney dysfunction.
  • Kidney stones: calcium precipitation in the urinary tract.
  • Allergic reaction: rash, itching, or swelling.
  • Hypervitaminosis D: toxicity from excessive vitamin D intake.
  • Hyperphosphatemia: elevated phosphate levels.
  • Acute pancreatitis: rare inflammation of the pancreas.

Precautions & Warnings

When using Maxi‑Kalz Vit. D3, consider the following safety measures.

  • Assess calcium status: check baseline serum calcium before initiating therapy.
  • Monitor vitamin D levels: periodic testing to avoid excess.
  • Avoid excessive intake: do not combine with other high‑dose calcium or vitamin D supplements.
  • Renal impairment: use with caution in patients with reduced kidney function.
  • Pregnancy/Breastfeeding: consult a healthcare professional before use.
  • Store at ambient temperature: keep below 25 °C, in the original packaging, protected from moisture and direct sunlight.

Avoid Interactions

Maxi‑Kalz Vit. D3 may interact with several medications.

Major Interactions (Avoid)

  • Thiazide diuretics: can increase calcium retention leading to hypercalcemia.
  • Digitalis glycosides: heightened calcium levels may enhance toxicity.
  • High‑dose vitamin A: combined excess may cause hypercalcemia.

Moderate Interactions (Monitor Closely)

  • Corticosteroids: may reduce calcium absorption, requiring monitoring.
  • Antacids containing aluminum or magnesium: can affect calcium absorption.
  • Cholesterol‑lowering statins: occasional reports of altered vitamin D metabolism.
  • Bisphosphonates: concurrent use may affect calcium balance.
  • Loop diuretics: may increase calcium excretion, necessitating dose adjustment.

Frequently Asked Questions

Maxi‑Kalz Vit. D3 is an oral supplement that provides vitamin D3 (colecalciferol) and calcium carbonate. It is used to correct or prevent calcium and vitamin D deficiencies, support bone health, and aid in the management of conditions such as osteomalacia, rickets, and osteoporosis.

Colecalciferol is converted in the liver to 25‑hydroxyvitamin D and then in the kidneys to the active hormone calcitriol. Calcitriol binds to vitamin D receptors in the intestine, increasing the absorption of calcium and phosphate, which are essential for bone mineralization and overall skeletal health.

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

Pregnant or breastfeeding individuals should consult their physician before using Maxi‑Kalz Vit. D3. While vitamin D and calcium are important during these periods, dosing must be individualized to avoid excess and ensure safety for both mother and child.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request trade or institutional credentials before providing pricing, availability, shipping details and any necessary import documentation.

Maxi‑Kalz Vit. D3 combines colecalciferol with calcium carbonate in a single oral tablet, offering a convenient source of both nutrients. Compared with products that contain only calcium or only vitamin D, it provides synergistic support for calcium absorption, potentially reducing the need for multiple supplements.

Store Maxi‑Kalz Vit. D3 at ambient temperature, preferably below 25 °C. Keep the tablets in the original container, protect them from moisture, heat and direct sunlight to maintain potency and stability throughout the shelf life.

Maxi‑Kalz Vit. D3 is taken orally, usually with a glass of water. It can be taken with or without food, but some individuals prefer taking it with meals to improve calcium absorption. Follow the dosing instructions provided by the prescribing healthcare professional.

The most serious risks include severe hypercalcemia, which can lead to cardiac arrhythmias, kidney stones, or renal impairment, and hypervitaminosis D, a condition caused by excessive vitamin D intake. Prompt medical attention is required if symptoms such as persistent nausea, vomiting, confusion, or muscle weakness occur.

Individuals with known hypersensitivity to colecalciferol, calcium carbonate, or any excipients in the tablet should avoid using the product. Patients with severe renal disease, hypercalcemia, or certain granulomatous disorders should consult a physician before starting supplementation.
