Eggshell Calcium + Vitamin D3: Brands, Price & Uses in Bangladesh

Eggshell Calcium + Vitamin D3 is a nutritional supplement combining natural eggshell-derived calcium carbonate with vitamin D3 (cholecalciferol). It is used for:

• Established uses: Prevention and treatment of dietary calcium deficiency; as a calcium and vitamin D supplement in individuals with inadequate dietary intake.
• Guideline-supported adjunct use: Adjunct to specific therapy in the management of osteoporosis and osteopenia, particularly in postmenopausal women and older adults, to reduce the risk of bone loss and fractures.
• Supportive use: Calcium and vitamin D supplementation during pregnancy and lactation when dietary intake is insufficient (as advised by a physician).
• Adjunct use: Supportive therapy in rickets, osteomalacia, and hypoparathyroidism, generally alongside specific medical management.

Eggshell Calcium + Vitamin D3 is not a substitute for prescription osteoporosis medications (e.g., bisphosphonates) but is commonly used alongside them to ensure adequate calcium and vitamin D status.

Administration: Eggshell Calcium + Vitamin D3 is taken orally, preferably with or after meals to enhance calcium absorption and reduce gastrointestinal upset. Tablets should be swallowed whole with water unless the product is labeled as chewable. Doses should be spread out over the day (e.g., morning and night) rather than taken all at once, as calcium absorption efficiency decreases at higher single doses.

Because eggshell-derived calcium carbonate is generally well tolerated, adverse effects with Eggshell Calcium + Vitamin D3 are usually mild and infrequent:

• Common: Constipation, bloating, gas, mild abdominal discomfort, and nausea.
• Less common: Loss of appetite, dry mouth, headache.
• Rare (usually with excessive or prolonged high-dose intake): Hypercalcemia, kidney stones, and metabolic alkalosis (see Overdose Effects and Contraindications).

Patients with known egg allergy may rarely experience hypersensitivity reactions due to the eggshell source; discontinue and seek medical advice if signs of allergic reaction occur.
