The following is the recommended dietary allowance (RDA) for calcium as published by National Academy of Sciences:

  • Infants
  • ** Age 0 to 6 months: 210 mg
    • Age 7 months to 1 year: 270 mg
  • Children
  • ** Age 1 to 3 years: 500 mg
    • Age 4 to 8 years: 800 mg
  • Women
  • ** Age 9 to 18 years: 1300 mg
    • Age 19 - 50 years: 1000 mg
    • Over Age 51 years: 1200 mg
    • *** Pregnancy
      • **** Under Age 19: 1300 mg
        • Age 19 and Over: 1000 mg
      • Lactating
      • **** Under Age 19: 1300 mg
        • Age 19 and Over: 1000 mg
  • Men
  • ** Age 9 to 18 years: 1300 mg
    • Age 19 - 50 years: 1000 mg
    • Over Age 51 years: 1200 mg

These recommendations were published in 2004 by the National Academy of Sciences

It may also be important to know that the body can not absorb more than 600mg of calcium at any time, so if taken as suppliments, it must be spaced out through the day. I would also add 200mg to the maleover 35 - 1.2g until 50 then 1.4g per day.
