Medical Reference
A.
The following doses have been studied in scientific research:

BY MOUTH:
  • For preventing low calcium levels: 1 gram elemental calcium daily is typically used.
  • For heartburn: Calcium carbonate as an antacid is usually 0.5-1.5 grams as needed.
  • To reduce phosphates in adults with chronic renal failure: The initial dose of calcium acetate is 1.334 grams (338 mg elemental calcium) with each meal, increasing to 2-2.67 grams (500-680 mg elemental calcium) with each meal if necessary.
  • For prevention of weak bones (osteoporosis) in postmenopausal women: Doses of 1-1.6 grams elemental calcium daily in divided doses (as carbonate, citrate, lactate gluconate, or citrate malate) to raise the intake of calcium to recommended levels.
  • For prevention of bone loss in premenopausal women over 40: A dose of 1 gram.
  • For pregnant women with low dietary calcium intake: The dose for increasing fetal bone density ranges from 300-1300 mg/day beginning at gestation week 20-22.
  • For premenstrual syndrome (PMS): 1-1.2 grams calcium per day as calcium carbonate.
  • For reducing thyroid hormone levels in people with chronic renal failure: 2-21 grams calcium carbonate.
  • To prevent bone loss in people taking corticosteroid drugs: Divided daily doses of 1 gram of elemental calcium daily.
  • For high blood pressure: 1-1.5 grams calcium daily.
  • For preventing high blood pressure during pregnancy (pre-eclampsia): 1-2 grams elemental calcium daily as calcium carbonate.
  • For preventing colorectal cancer and recurrent colorectal benign tumors (adenomas): Calcium 1200-1600 mg/day.
  • For high cholesterol: 1200 mg daily with or without vitamin D 400 IU daily has been used in conjunction with a low-fat or calorie-restricted diet.
  • For preventing fluoride poisoning in children: Calcium 125 mg twice daily, in combination with ascorbic acid and vitamin D.
  • For weight loss, increasing calcium consumption from dairy products to a total intake of 500-2400 mg/day in combination with a calorie-restricted diet has been used.
Calcium carbonate and calcium citrate are the two most commonly used forms of calcium.

Calcium supplements are usually divided into two doses daily in order to increase absorption. It’s best to take calcium with food in doses of 500 mg or less.

The daily Dietary Reference Intakes (DRI) for elemental calcium are: Age 1-3 years, 500 mg; 4-8 years, 800 mg; 9-18 years, 1300 mg; 19-50 years, 1000 mg; 51+ years, 1200 mg; pregnant or breast-feeding (under 19 years), 1300 mg; pregnant or breast-feeding (19-50 years), 1000 mg. The daily upper intake level (UL) for calcium is 2.5 grams for everyone over one year of age.
