What are the recommended daily amounts of calcium?


Suggested daily amounts of calcium vary by age. The National Academy of Sciences Institute of Medicine developed these recommendations for (adequate) daily calcium intake:

  • Age 0 to 6 months: 210 mg
  • Age 7 to 12 months: 270 mg
  • Age 1 to 3 yeas: 500 mg
  • Age 4 to 8 years: 800 mg
  • Age 9 to 13 years: 1,300 mg
  • Age 14 to 18 years: 1,300 mg (including when a female is pregnant or breastfeeding)
  • Age 19 to 50: 1,000 mg (including when a female is pregnant or breastfeeding)
  • Age 51 + years: 1,200 mg

A variety of foods provide calcium, including dairy products and certain vegetables, such as spinach. Some people are unable to get the necessary amount of calcium from diet alone - for example, they may follow a vegan diet, which does not allow dairy products, or they may be lactose intolerant, which means they have difficulty digesting dairy products without experiencing intestinal discomfort.

Calcium supplements are also recommended to help prevent or reverse osteoporosis. Your healthcare provider can discuss whether supplementation is right for you depending on your overall health status, other medications and supplements you take, and a range of other factors.
