Drug Interactions: Calcium can interfere with tetracycline antibiotics and calcium channel blockers. Consult your physician before use if you are taking any thiazide diuretics, as these can cause extremely high (potentially toxic) levels of calcium in the body.

Nutrient Depletions: Calcium can impair the absorption of the mineral iron. Foods high in phosphorus (animal protein and soft drinks) promote urinary loss of calcium. High consumption of caffeine, and excess dietary fat and fibre can inhibit calcium absorption. Calcium may be depleted by corticosteroids, bronchodilators, anti-osteoporotics, cholesterol-reducing medications, anti-gout medications, and sulfonamides.

Supportive Interactions: Vitamin D enhances calcium absorption. Ensure that you are getting at least 400 IU of Vitamin D each day for optimal calcium absorption.

Warnings and Precautions: None known when taken as directed.

Toxicity, Adverse Warnings and Side Effects: Calcium carbonate may cause symptoms of gas, bloating or constipation. If this occurs, switch to calcium citrate. Do not exceed recommended dosage. Excess calcium can contribute to the development of kidneys stones, and may cause calcium deposits in the body.
