Maacal-D is a combination of Calcium Carbonate and Vitamin D3 (Cholecalciferol), formulated to prevent and treat calcium and vitamin D deficiency and support overall bone health.
Calcium is essential for the normal functioning of bones, muscles, nerves, and other vital organs. When blood calcium levels are low, the body draws calcium from bones, leading to bone weakening and disorders. Vitamin D3 enhances intestinal absorption of calcium, ensuring optimal bone mineralization and muscle health.

It is also recommended to ensure adequate calcium and vitamin D intake in conditions such as:
500 mg & 200 IU strength:
Each film-coated tablet contains Calcium Carbonate BP (eggshell source) 1250 mg, equivalent to 500 mg elemental calcium, and Vitamin D3 BP 200 IU.
600 mg & 400 IU strength:
Each film-coated tablet contains Calcium Carbonate BP (eggshell source) 1500 mg, equivalent to 600 mg elemental calcium, and Vitamin D3 BP 400 IU.
Osteoporosis induced by long-term use of drugs such as phenytoin, phenobarbital, or corticosteroids (e.g., prednisolone)
Maacal-D contains calcium derived from European eggshell, a natural and eco-friendly source with superior bioavailability. Along with calcium, it provides trace amounts of essential minerals such as magnesium, phosphorus, and strontium, which contribute to bone formation and strength.
This formulation is:
Highly digestible (≈98%)
More absorbable than algae-, coral-, or rock-based calcium
Designed to enhance calcium fixation in bones, improve bone density, and strengthen the organic bone matrix
Enriched with natural transport proteins to maximize calcium absorption
With medicines:
May interact with digoxin, antacids containing calcium/aluminum/magnesium, other calcium supplements, calcitriol, and tetracycline antibiotics (e.g., doxycycline, oxytetracycline). Medical consultation is advised before concurrent use.
With food:
Calcium absorption may be reduced when taken with certain foods such as spinach, milk, and dairy products.
Concomitant digoxin therapy (requires close monitoring of serum calcium)
Recommended dose: One tablet in the morning and one tablet at night, or as directed by the physician.
Use in children and adolescents should be based on medical advice.
