Non-Dairy Calcium

Calcium from alternative sources to dairy products.

Definition

Calcium from sources other than dairy products, such as certain minerals, dietary supplements, or mineral waters, used particularly in people intolerant of dairy products.

How it works

Non-dairy calcium includes calcium supplements in different forms (carbonate, citrate) and mineral waters rich in calcium. The bioavailability of supplemented calcium varies depending on its form: calcium citrate is better absorbed than carbonate, especially in people with low gastric acidity. Calcium carbonate requires gastric acidity to be absorbed and should be taken with meals. These sources can be useful to cover insufficient intake in people intolerant of dairy products.

Role

Provide an alternative source of calcium in case of lactose intolerance or a diet excluding dairy products.

Examples

  • Calcium carbonate (supplement)
  • Calcium citrate (supplement)
  • Mineral water with calcium (500 mg/L)
  • Prescribed calcium tablets

Recommendations

Fractionate the intake into several doses of up to 500 mg to improve absorption. Take calcium citrate with or without meals, calcium carbonate with meals. Consult a healthcare professional for choosing the appropriate supplement.

Key takeaway

Non-dairy calcium is a valid option to achieve the recommended intake in case of intolerance or restriction.
