CALCIOM-500

Calciom-500 Tablets 

I checked the uploaded image closely. The front of the pack clearly states “Calcium Carbonate & Vit. D3 Tablets” and identifies the product as Calciom-500. The exact strength panel is not visible in the photograph, so the safest way to state the composition is to distinguish the confirmed ingredients from the likely strength.

1. Calcium Carbonate

Calcium carbonate (CaCO₃) is the calcium salt used as the principal calcium source.

An important distinction is that 500 mg of calcium carbonate is not equivalent to 500 mg of elemental calcium. Calcium carbonate contains approximately 40% elemental calcium by weight.

Therefore, approximately:

1,250 mg Calcium Carbonate → 500 mg elemental Calcium

This type of formulation is commonly described as:

Calcium Carbonate 1,250 mg equivalent to Elemental Calcium 500 mg

Calcium is required for:

• Formation and maintenance of bones and teeth

• Normal muscle contraction

• Normal nerve transmission

• Normal cardiac function

• Blood-clotting processes

• Various cellular signalling processes

Calcium carbonate also has antacid properties, although in a calcium supplement its principal purpose is calcium replacement/supplementation.

2. Vitamin D3 (Cholecalciferol)

Vitamin D3 is cholecalciferol, a fat-soluble vitamin.

Its major relevance in this combination is calcium absorption.

Vitamin D3 is metabolized in the body to active vitamin-D metabolites that help regulate calcium and phosphate homeostasis.

In simplified terms:

Vitamin D3 → improved intestinal calcium absorption → better calcium availability → support for bone mineralization

Thus, combining calcium with vitamin D3 is useful when supplementation of both nutrients is required.

Why Calcium + Vitamin D3 are combined

Taking calcium alone does not address all aspects of calcium metabolism.

The combination provides:

Calcium carbonate
↓
Provides calcium

Vitamin D3
↓
Supports calcium absorption and utilization

Together
↓
Support normal bone and mineral metabolism.

Important composition point

The image does not show a readable numerical value for Vitamin D3. Calcium/vitamin-D products can contain different D3 strengths, so I would not assume a particular IU value from the product name alone.

For comparison, other calcium carbonate + vitamin D3 products can contain strengths such as 100, 200, 250, 400 IU or higher. The exact Calciom-500 strength should therefore be taken from its strip, carton side panel, or package insert rather than guessed. (Scribd)

In pharmaceutical notation

The composition is intended to be represented approximately as:

Each tablet contains:
Calcium Carbonate — 1,250 mg
Equivalent to elemental Calcium — 500 mg
Vitamin D3 (Cholecalciferol) — exact strength to be confirmed
Excipients — q.s.

I would not fill in the Vitamin D3 IU from this photograph, because it isn't readable.

If you upload a clear photo of the back/side of the Calciom-500 box or one tablet strip, I can give you the exact composition (mg/IU), mechanism, indications, dosage, contraindications, adverse effects, drug interactions, precautions, and counselling points.
