In the pharmaceutical industry, Shelcal 500 is a leading brand of Calcium and Vitamin D3 supplements. As a pharmacist and manufacturer, I can tell you that the standard adult dosage is typically one tablet once or twice daily.

However, the “best” frequency depends on how your body absorbs the elemental calcium.

Standard Dosage Guidelines

Goal	Typical Dose	Frequency
Daily Maintenance	500 mg	Once Daily
Osteoporosis / Pregnancy	1000 mg	Twice Daily (split into morning and evening)

The “500 mg Rule” for Absorption

The human body has a physical limit on how much calcium it can absorb at one single time.

• Saturation Point: The efficiency of calcium absorption decreases significantly as the dose increases. The body absorbs calcium best in doses of 500 mg or less.

• Why Split the Dose? If you are prescribed 1000 mg per day, taking two Shelcal 500 tablets at once is wasteful. Taking one in the morning and one in the evening ensures that your body absorbs the maximum amount of elemental calcium from each tablet.

The Pharmacist’s “Golden Rules” for Shelcal 500

As you develop your digital platforms and e-commerce marketplace, providing these “Technical Tips” will establish your firm’s authority:

Take with Food: Shelcal 500 contains Calcium Carbonate, which requires stomach acid for optimal absorption. Taking it after a meal is highly recommended.

Hydration: Always take the tablet with a full glass of water to reduce the risk of constipation, a common side effect of calcium supplements.

Interaction Gap: As a pharmacist, you know that calcium can interfere with the absorption of other drugs. It should be taken at least 2 hours apart from antibiotics (like Ciprofloxacin) or Iron supplements.

The Manufacturer’s Perspective: Technical & Export

From a production and B2B standpoint at your WHO-GMP facility in Mumbai, Shelcal 500 is a benchmark for quality:

• Elemental Yield: Shelcal 500 provides 500 mg of elemental calcium from 1250 mg of Calcium Carbonate. On your marketplace, highlighting the elemental value is a major USP, as many low-quality generics only list the total salt weight.

• Stability of D3: Cholecalciferol (Vitamin D3) is highly unstable. At our facility, we utilize Alu-Alu blister packaging and specialized stabilized Vitamin D3 granules to ensure the product maintains its potency for 36 months in tropical Zone IVb regions.

• Dossier Support: Since bone health is a priority for global health tenders, we provide full CTD/eCTD Dossiers to support your firm in registering this as a high-quality alternative to major brands.
