Ingredients of Tab Supracal
Tab Supracal primarily contains calcium carbonate as its main ingredient, providing 40% elemental calcium, along with vitamin D3 (cholecalciferol) for optimal calcium absorption. While the exact formulation details of Supracal specifically aren't provided in the evidence, calcium supplements typically follow standard formulations.
Main Components
- Calcium Carbonate: The primary active ingredient, providing 40% elemental calcium 1
- Vitamin D3 (Cholecalciferol): Typically 400-800 IU to enhance calcium absorption 2
Additional Ingredients
Calcium supplements commonly contain:
- Binding agents
- Flavorings (if chewable)
- Colorants
- Preservatives
Calcium Content and Formulation
Calcium carbonate is the most cost-effective and concentrated form of calcium supplementation 3. Each tablet likely contains:
- 500-1250 mg of calcium carbonate
- Providing approximately 200-500 mg of elemental calcium per tablet
The formulation is designed for optimal absorption when taken with food, as calcium carbonate requires gastric acid for proper absorption 4.
Absorption Considerations
- Calcium carbonate should be taken with meals to ensure optimal absorption 3
- Maximum absorption occurs when doses are limited to 500 mg of elemental calcium at one time 2
- The supplement may be available in chewable tablet form for better palatability 5, 6
Clinical Implications
When taking calcium supplements:
- Divided doses are recommended for better absorption (no more than 500-600 mg elemental calcium per dose) 4
- Total daily calcium intake from all sources (diet plus supplements) should not exceed 2000-2500 mg 2
- Vitamin D is essential for calcium absorption, with recommended daily intake of 800-1000 IU for adults over 50 2
Potential Side Effects
- Gastrointestinal complaints (constipation, bloating, gas) are the most common side effects 3, 7
- Hypercalcemia may occur in some patients 7
- Elevated serum uric acid levels have been observed with calcium and vitamin D supplementation 7
Calcium carbonate supplements like Supracal are widely used for calcium supplementation in various conditions including osteoporosis prevention and treatment, always as part of a comprehensive approach that includes adequate vitamin D.
