Mastical (Calcium Carbonate)

When taken orally, calcium carbonate dissolves in stomach acid, releasing calcium ions. These ions are absorbed through the intestinal wall and become available for incorporation into hydroxyapatite, the mineral that gives bone its strength, as well as for enzymatic processes that require calcium, such as muscle contraction and nerve signaling.

The appropriate dose of Mastical is determined by a qualified health‑care professional based on the patient’s age, dietary calcium intake, underlying health conditions, and specific therapeutic goals. Patients should follow the prescribing clinician’s instructions and not exceed the recommended amount without medical advice.

Calcium is an essential nutrient during pregnancy and lactation, but the safety of any supplement, including Mastical, should be evaluated by a physician. A prescriber can assess individual calcium needs and decide whether Mastical is appropriate, considering any other medications or health conditions.

To request Mastical, visit the product page on gnhindia.com, enter the desired quantity, and submit the enquiry form. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and the necessary import documentation.

Mastical provides calcium carbonate, which typically contains a higher elemental calcium percentage than calcium citrate or calcium gluconate, making it a cost‑effective option for many patients. However, calcium carbonate requires an acidic environment for optimal absorption, so individuals with reduced stomach acidity may prefer alternative calcium salts. The choice depends on clinical needs, tolerability, and physician recommendation.

Mastical tablets should be stored at ambient temperature, preferably below 25 °C. Keep them in the original packaging to protect from moisture and direct sunlight. Do not store in bathrooms or near heat sources, and keep out of reach of children.

Mastical is taken orally with a full glass of water. It can be taken with or without food, but if gastrointestinal upset occurs, it may be helpful to ingest the tablet with meals. Patients should follow the timing instructions provided by their prescriber, especially when other medications are involved.

The most serious adverse events associated with calcium carbonate include hypercalcemia, which can cause weakness, confusion, cardiac arrhythmias, and kidney stone formation in susceptible individuals. If any signs of severe constipation, unexplained abdominal pain, or allergic reactions such as rash or breathing difficulty appear, medical attention should be sought promptly.

Mastical should be avoided by individuals with known hypersensitivity to calcium carbonate or any excipients in the tablet. Patients with severe renal impairment, hypercalcemia, or a history of calcium‑containing kidney stones should consult a health‑care professional before using this supplement.
