Shelcal 500 Calcium+Vitamin D3 Tablet

Shelcal 500 is a high-potency nutritional intervention containing Calcium Carbonate (500mg elemental calcium) and Vitamin D3 (Cholecalciferol 250 IU), specifically engineered for the clinical management of hypocalcemia, osteoporosis, and osteomalacia. Utilizing a unique “Bio-Active Absorption” system, this tablet works by providing the essential substrates for bone mineralization. Calcium Carbonate serves as a concentrated mineral source, while Vitamin D3 acts as a critical hormonal regulator that facilitates the active transport of calcium across the intestinal mucosa. By maintaining optimal serum calcium levels, Shelcal effectively inhibits the release of parathyroid hormone (PTH), thereby preventing excessive bone resorption. This targeted biochemical action provides a decisive therapeutic response by strengthening the skeletal matrix and reducing the risk of fragility fractures.

Key Features

Specifically formulated to provide 500mg of elemental calcium per tablet to meet daily physiological requirements efficiently.
Clinically recognized for its role in enhancing calcium bioavailability and supporting neuromuscular function.
Acts as a functional building block for the hydroxyapatite crystals that form the structural framework of bones and teeth.
Specifically engineered to assist in the suppression of secondary hyperparathyroidism in calcium-deficient states.
Formulated to ensure rapid disintegration and maximum ionic release within the gastric environment.

Key Ingredients

Calcium Carbonate (from Oyster Shell or Synthetic Source)
Vitamin D3 (Cholecalciferol)
Microcrystalline Cellulose
Magnesium Stearate
Povidone

Precautions

Consult with a healthcare professional before use, especially if you have a history of kidney stones (nephrolithiasis) or renal impairment.
Contraindicated in patients with elevated blood calcium levels, hypervitaminosis D, or certain bone tumors.
Calcium can interfere with the absorption of certain antibiotics (tetracyclines, quinolones) and iron supplements; space doses by at least 2–4 hours.
Use with caution if you are taking digitalis glycosides (digoxin), as high calcium levels can increase the risk of cardiac arrhythmias.
Some users may experience mild constipation or flatulence; increasing fiber and water intake can help mitigate these symptoms.
Patients with sarcoidosis should be monitored closely due to the potential for increased sensitivity to Vitamin D3.

How to Use

Swallow the tablet whole with a full glass of water. Do not crush or chew the tablet unless specifically directed by a physician.
For optimal clinical results, take Shelcal 500 with a meal. The presence of food triggers gastric acid production, which enhances the solubility and absorption of calcium carbonate.
Typically taken as one tablet daily, or as prescribed by your healthcare provider based on your specific biochemical needs.
Maintain a strict daily schedule to ensure a steady supply of minerals for bone remodeling and systemic functions.
Limit excessive intake of caffeine and alcohol, as these substances can interfere with calcium absorption and increase urinary excretion.
Keep the tablets in their original container, stored in a cool, dry place (below 30°C) away from moisture and direct sunlight.
