Indications & Clinical Uses

Natecal D Flas is a nutritional supplement that addresses mineral and vitamin deficiencies affecting bone metabolism.

  • Calcium deficiency: helps restore normal calcium levels in the body.
  • Vitamin D deficiency: provides vitamin D to improve serum 25‑hydroxyvitamin D concentrations.
  • Bone health maintenance: supports bone mineralization and may reduce risk of osteoporotic fractures.

How It Works

  • Colecalciferol is converted in the liver and kidneys to the active hormone 1,25‑dihydroxyvitamin D, which enhances intestinal absorption of calcium and phosphate. Calcium carbonate supplies elemental calcium that, together with the increased absorption, raises serum calcium concentrations and provides the substrate needed for bone mineralization and remodeling.

Side Effects

Adverse reactions may occur, although many users experience no problems.

Common Side Effects

  • Nausea: mild stomach upset after ingestion.
  • Constipation: reduced bowel movements.
  • Abdominal discomfort: cramping or bloating.
  • Flatulence: increased gas production.
  • Mild hypercalcemia: transient elevated calcium levels without symptoms.
  • Headache: occasional mild headache.

Serious or Rare Side Effects

  • Severe hypercalcemia: symptoms such as confusion, arrhythmia, or kidney impairment.
  • Kidney stones: formation due to excess calcium.
  • Allergic reaction: rash, itching, swelling, or difficulty breathing.
  • Hypervitaminosis D: toxicity from excessive vitamin D leading to calcium overload.
  • Hyperphosphatemia: elevated phosphate levels in rare cases.
  • Acute pancreatitis: very rare inflammatory pancreas response.

Precautions & Warnings

Before using Natecal D Flas, consider the following safety measures.

  • Assess renal function: impaired kidneys may affect calcium handling.
  • Monitor serum calcium: avoid excessive levels, especially in patients on other calcium sources.
  • Evaluate vitamin D status: adjust dose if baseline levels are already sufficient.
  • Review concomitant medications: certain drugs may increase calcium or vitamin D effects.
  • Pregnancy and lactation: 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

Natecal D Flas can interact with other medicines; awareness of the interaction level helps manage risk.

Major Interactions (Avoid)

  • Thiazide diuretics: may cause significant hypercalcemia.
  • Vitamin D analogues: risk of additive hypervitaminosis D.
  • Calcium channel blockers: potential alteration of calcium balance.

Moderate Interactions (Monitor Closely)

  • Bisphosphonates: may reduce absorption if taken simultaneously.
  • Antacids containing aluminum or magnesium: can interfere with calcium carbonate absorption.
  • Corticosteroids: may increase calcium loss, requiring dose adjustment.

Frequently Asked Questions

Natecal D Flas is an oral nutritional supplement that provides calcium carbonate and colecalciferol (vitamin D3) to address calcium and vitamin D deficiencies and to support normal bone mineralization in adults.

Colecalciferol is converted by the liver and kidneys into the active hormone 1,25‑dihydroxyvitamin D, which increases intestinal absorption of calcium and phosphate, thereby raising serum calcium levels and facilitating bone mineral formation.

The appropriate dose of Natecal D Flas is determined by the prescribing healthcare professional based on the patient’s age, nutritional status, laboratory results and any concurrent therapies.

Pregnant or breastfeeding individuals should discuss use with their physician. Calcium and vitamin D are essential nutrients, but dosing should be individualized to avoid excess, especially when other supplements are taken.

Submit an enquiry on the product page at gnhindia.com, specifying the required quantity. 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 D Flas combines calcium carbonate with colecalciferol in a single oral formulation, offering a convenient source of both nutrients. Compared with products that contain only calcium or only vitamin D, it addresses two deficiencies simultaneously, which may simplify dosing regimens.

Store the product at ambient temperature, preferably below 25 °C. Keep it in the original packaging, protect it from moisture and direct sunlight, and ensure the container is tightly closed to maintain stability.

Natecal D Flas is taken orally, usually with water. It can be taken with or without food, but patients should follow the specific instructions provided by their healthcare provider.

The most serious risks include severe hypercalcemia, kidney stone formation, and hypervitaminosis D, which can lead to calcium overload and organ dysfunction. Patients should report symptoms such as persistent nausea, vomiting, confusion or severe abdominal pain to a clinician.

Individuals with known hypersensitivity to colecalciferol, calcium carbonate, or any excipients, as well as patients with severe renal impairment, hypercalcemia, or certain granulomatous diseases, should avoid using Natecal D Flas unless advised otherwise by a physician.
