Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Gemcal Suspension 120 ml contains Calcium Phosphate (150mg) + Magnesium (75mg) + Zinc Gluconate (4mg) + Vitamin D3 (200IU). It belongs to the Vitamin D / calcium supplement, Vitamin and mineral supplement and Antioxidant / trace element supplement class of medicines.
Treatment of Nutritional deficiencies
GEMcal P Suspension is a combination of calcium phosphate, magnesium, zinc gluconate, and vitamin D3. Calcium phosphate provides the main building blocks for bone strength. Vitamin D3 improves calcium absorption from the gut and helps deposit it into bones. Magnesium regulates calcium transport and supports bone mineralization. Zinc aids in bone tissue growth and repair. Together, they ensure proper bone formation, density, and maintenance, lowering the risk of fragility and bone disorders.
Take this medicine in the dose and duration as advised by your doctor. Check the label for directions before use. Measure it with a measuring cup and take it by mouth. Shake well before use. GEMcal P Suspension may be taken with or without food.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of GEMcal P Suspension, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
An overdose of this medicine can raise blood calcium dangerously, causing thirst, frequent urination, vomiting, confusion and kidney damage. It can cause vomiting and stomach pain, and with iron can be dangerous, especially in children. It can cause vomiting, stomach pain and, with some minerals, damage over the longer term. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Gemcal are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Do not take more than your doctor has advised. Vitamin D builds up in the body and too much raises blood calcium, causing thirst, frequent urination, nausea and confusion. High-dose weekly or monthly sachets are prescription strengths — do not repeat one because you missed a week. Tell your doctor if you have had kidney stones or have kidney disease. A supplement is not a substitute for a balanced diet or for treating the cause of a symptom. Iron makes stools black and can cause constipation — this is expected, but tell your doctor if it troubles you. Keep iron-containing products well out of reach of children; an overdose in a small child is a medical emergency. Check the labels of everything you take so you do not double up on the same nutrient. A supplement supports a normal diet; it does not prevent or treat infection. Zinc on an empty stomach commonly causes nausea — take it with food. Very high doses of vitamin A over a long period can be harmful, particularly in pregnancy. Do not take several products containing the same nutrient at once; the totals add up.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with a high blood calcium level, or with certain kidney stones.
Calcium reduces the absorption of thyroid tablets, several antibiotics and iron — separate them by a few hours. Water tablets of the thiazide group raise calcium further when combined. Iron, calcium, zinc and magnesium reduce the absorption of thyroid tablets and several antibiotics — separate them by a few hours. Tea and coffee taken with iron reduce how much is absorbed; vitamin C increases it. Zinc and other minerals reduce the absorption of some antibiotics — separate them by a few hours. Tell your doctor if you take a blood thinner, as high-dose vitamin E can add to its effect.
Store below 30°C, away from direct sunlight. Do not freeze. Once opened, use it within the period printed on the pack. Keep out of the reach of children.
Take GEMcal P Suspension regularly for maximum benefit. It works best as a long-term supplement. Adequate sunlight exposure and a balanced diet rich in calcium and protein will improve GEMcal P Suspension effectiveness. Stay hydrated and include fiber-rich foods in your diet to help prevent constipation. Do not take more than the prescribed dose. Too much calcium or vitamin D can be harmful. Inform your doctor if you have high calcium levels or if you are on other medications.
