Calcium carbonate Pregnancy Warnings
Calcium carbonate has not been formally assigned to a pregnancy category by the FDA. Animal reproductive studies and data from controlled human studies are not available. Calcium carbonate is commonly used safely to provide calcium supplementation during human pregnancy. Calcium carbonate should only be used during pregnancy when benefit outweighs risk.
Calcium is transported across the human placenta. The human fetus is entirely dependent on its mother for the supply of nutrients--including calcium--and oxygen and removal of waste products. Fetal accumulation of calcium occurs mainly during the third trimester. By the end of normal human pregnancy the fetus acquires approximately 28 grams of calcium and 16 grams of phosphorus for skeletal development. The recommended daily calcium supplementation for a pregnant woman averages 1,200 mg (compared to 800 mg/day in the nonpregnant adult), with an additional 250 to 300 mg/day recommended during the last trimester. One quart of milk contains approximately 1,200 mg of calcium; women who do not consume milk or milk products may require calcium supplementation. The milk-alkali syndrome associated with calcium carbonate has been reported during human pregnancy. In one case, after resolution of hypercalcemia, a 31-year-old woman delivered a stillborn fetus with short limbs and low-set ears at 37 weeks' gestation. Chromosomal analysis was normal, and autopsy revealed no evidence of tissue calcification. In another case, a 31-year-old woman delivered a normal 2,950 gram male infant.
Calcium carbonate Breastfeeding Warnings
The calcium content of human milk averages 30 mg/dl. The recommended daily allowance (RDA) for calcium in the lactating woman is 1,200 mg (compared to 400 mg/day in the nonlactating adult). One quart of milk contains approximately 1,200 mg of calcium. Women who do not consume milk or milk products may require calcium supplementation.
There are no data on the excretion of calcium carbonate into human milk. Calcium is considered a normal component of human milk.
