Sources of calcium include milk, yogurt, cheese, leafy greens and fortified products like cereal and juice. One cup of plain yogurt contains 488 mg of calcium, 8 ounces of milk has 301 mg of calcium and one half cup of spinach has 136 mg. Prenatal vitamins also contain part of your daily recommended amount of calcium. According to Babycenter, your body can only absorb 500 mg of calcium at a time, so try to spread out your intake of calcium food sources or supplements throughout the day
e.g. 1 slice of kraft cheese can also supplement abt 20% of daily requirements
