Calcium + Vitamin D3 Tablets
Manufactured by: Healthy Life Pharma Pvt. Ltd. (WHO-GMP Certified)
Exported by: Healthy Inc (Star Export House)
1. Product Introduction
Healthy Life Pharma Pvt. Ltd. is a specialized Manufacturer of Calcium Carbonate and Vitamin D3 Tablets in India. This combination is the foundational supplement for Bone Health. Calcium is the primary building block of bone tissue, while Vitamin D3 is the essential “key” that allows the body to absorb Calcium from the gut. Without D3, calcium supplements are largely ineffective. This formulation is globally prescribed for the prevention and treatment of Osteoporosis, Osteopenia, and calcium deficiency during pregnancy and lactation.
We offer Contract Manufacturing (Third Party) services for this high-volume nutritional product. Calcium tablets can be bulky and chalky. Our WHO-GMP certified facility in Mumbai utilizes high-density granulation technology to produce tablets that contain a high elemental dose (500mg) yet remain compact and easy to swallow. Healthy Inc manages the export logistics, supplying antenatal clinics, geriatric care centers, and pharmacy chains across Africa, Southeast Asia, and the Middle East.

3. Manufacturing Technology
Building strong bones, one tablet at a time.
The Manufacturer: Healthy Life Pharma Pvt. Ltd.
Vitamin D3 Stability: Vitamin D3 oxidizes easily. We use Stabilized Vitamin D3 powder (protected by an antioxidant matrix) and overage calculations to ensure the potency remains 100% throughout the shelf life, even in warm climates.
Compact Formulation: 1250mg of Calcium Carbonate is a large volume of powder. We use High-Shear Wet Granulation to densify the powder, allowing us to compress it into a streamlined, patient-friendly tablet size without compromising dissolution time.
Bioavailability: We ensure the tablet disintegrates rapidly in the acidic environment of the stomach, which is necessary to solubilize the calcium carbonate for absorption.
The Exporter: Healthy Inc
Family Packs: We specialize in bulk “Family Jars” (100s or 500s) which are popular in export markets for long-term maintenance therapy.
4. Quality Assurance
We adhere to strict Pharmacopoeial standards:
Assay: We confirm the potency of both Calcium and Vitamin D3 is strictly within label claim limits (90-110% for Calcium, 90-125% for D3).
Dissolution: We test release profiles to ensure >75% release within 30 minutes in 0.1N HCl.
Heavy Metals: We rigorously test the raw Calcium Carbonate (especially if oyster-derived) to ensure it is free from Lead, Arsenic, and Mercury.
5. Why Use Calcium + Vitamin D3?
The perfect pair for skeletal strength.
Mechanism:
Calcium: Mineralizes the bone matrix, giving it hardness and strength.
Vitamin D3: Acts on the intestine to increase Calcium absorption efficiency by 30-40%. It also regulates Calcium reabsorption in the kidneys.
Key Indications:
Osteoporosis: Prevention of fractures in post-menopausal women and the elderly.
Pregnancy & Lactation: Meeting the high calcium demands of the developing fetus and nursing infant.
Rickets / Osteomalacia: Softening of bones due to deficiency.

7. Frequently Asked Questions
Q: Who manufactures Calcium + Vitamin D3 Tablets?
A: Healthy Life Pharma Pvt. Ltd. manufactures them in India.
Q: Is it Shellcal?
A: Shellcal is a popular brand name. We manufacture the Generic Equivalent (Calcium Carbonate + Vit D3), often using the same oyster shell source.
Q: Can it cause kidney stones?
A: Excessive use can. Patients with a history of kidney stones should consult a doctor. Drinking plenty of water helps reduce this risk.
Q: When should I take it?
A: After a meal. Calcium Carbonate requires stomach acid to dissolve properly. Taking it after food ensures there is enough acid for absorption.
