Introduction
Calfer-D tablet is a nutritional supplement containing Calcium and Vitamin D3 (Cholecalciferol). Some formulations may also include other minerals like Zinc and Magnesium. It is designed to prevent or treat deficiencies in these vital nutrients, which are crucial for maintaining strong bones and overall health. While “Calfer D” itself might not be the most common brand name globally or specifically in Pakistan (where similar products like Osnate-D, Calpro-D, Calfor-D, or Calray-D exist), this article covers the general properties, uses, and considerations for tablets combining Calcium and Vitamin D3.
Composition and Mechanism of Action
- Calcium: This essential mineral is the building block for strong bones and teeth. It’s also vital for proper nerve transmission, muscle function, blood clotting, and hormone secretion. If dietary intake is insufficient, the body draws calcium from the bones, weakening them over time. Calcium in these supplements is often in the form of Calcium Carbonate.
- Vitamin D3 (Cholecalciferol): Often called the “sunshine vitamin,” Vitamin D3 plays a critical role in helping the body absorb calcium and phosphorus from the intestines. Adequate Vitamin D3 levels are necessary for bone formation, growth, and regeneration. It also supports immune function, cell growth, and neuromuscular health.
- Other Minerals (in some formulations):
- Zinc: Supports bone-building cells and inhibits cells that break down bone tissue.
- Magnesium: Aids in calcium absorption by helping to convert Vitamin D into its active form.
Uses Of Calfer-D Tablet
Calcium and Vitamin D3 tablets like Calfer-D are used to:
- Prevent and Treat Deficiencies: Address low levels of calcium and/or Vitamin D3 due to poor diet, lack of sun exposure, or certain medical conditions.
- Manage Bone Conditions:
- Osteoporosis: Treat and prevent bone loss, reducing fracture risk, especially in postmenopausal women and the elderly.
- Osteomalacia (Adults) & Rickets (Children): Treat softening of the bones caused by severe Vitamin D deficiency.
- Support Parathyroid Health: Manage conditions caused by decreased activity of the parathyroid gland (hypoparathyroidism).
- Meet Increased Needs: Provide supplemental calcium and vitamin D during periods of high demand, such as pregnancy, breastfeeding, and periods of growth.
- Adjunct Therapy: Support healing in cases of bone fractures with delayed callus formation.
- Chronic Kidney Disease: Sometimes used as a phosphate binder.
Dosage
- The typical dosage often involves taking one or two tablets daily, usually divided into two doses (e.g., one tablet twice daily).
- It’s generally recommended to take these tablets with or shortly after a meal to enhance calcium absorption.
- Always follow the dosage prescribed by your doctor or pharmacist. Do not take more than the recommended amount.
- The specific dose depends on your age, medical condition, calcium/vitamin D levels, and dietary intake.
- Chewable tablets should be chewed thoroughly before swallowing.

When taken as directed, Calfer-D is generally well-tolerated. However, some side effects may occur:
- Common: Constipation, gas, bloating, upset stomach.
- Less Common: Nausea, vomiting, loss of appetite, headache, dry mouth, metallic taste.
- Signs of High Calcium/Vitamin D (Hypercalcemia/Hypervitaminosis D – require medical attention): Increased thirst, increased urination, unusual tiredness or weakness, confusion, bone pain, nausea/vomiting, constipation.
- Rare but Serious: Allergic reactions (rash, itching, swelling, severe dizziness, trouble breathing), kidney stones (especially with excessive intake).
