Calcium to baby from mother

Do you know how much calcium the fetus take from mother?
It is around 3000mgs.
That is from the bones of the mother.
So to fulfill these needs, the mother should take more calcium.
Though dietary products can supply some amount of calcium, supplementation is needed to fulfill the needs of mother and baby.

 Calcium supplements are usually advised after 12 to 14 weeks of pregnancy as calcium needs of the baby increases after this gestational age.
During first half of the pregnancy the woman should take around 500mgs of calcium per day.
In the second half of the pregnancy and during lactation around 1000 to 1200mg per day supplementation is needed.
Calcium supplements should not be taken along with iron or zinc or magnesium, as these can affect the absorption of calcium.
Some women may think that lactation may decrease their calcium levels.
During lactating period, the lactating women may have low calcium levels compared with nonlactating women.
But after lactation usually the women who have breastfed will have more bone mineral density compared with nonlactating women.
So breast feeding is advised always.
