Minerals Calcium ◆ Pregnant women absorb more of the calcium they consume and lose less calcium in the urine than do nonpregnant women. ◆ The fetus retains about 30 grams of calcium over the course of gestation. Most of the calcium is deposited in the last trimester when the fetal skeleton is growing most rapidly and the teeth are forming. RNI 800mg 1st trimester 1000mg 2nd trimester 1200mg 3rd trimester food source: milk and dairy products
