Breastfeeding also affects a mother's bones. Studies have shown that women often lose 3 to 5 percent of their bone mass during breastfeeding, although they recover it rapidly after weaning. This bone loss may be caused by the growing baby's increased need for calcium, which is drawn from the mother's bones.
The amount of calcium the mother needs depends on the amount of breast milk produced and how long breastfeeding continues. Women also may lose bone mass during breastfeeding because they're producing less estrogen, which is the hormone that protects bones. The good news is that, like bone lost during pregnancy, bone lost during breastfeeding is usually recovered within 6 months after breastfeeding ends. [quoted from NIAMS]
These are all the supplement I am currently taking. Why I chose Blackmores? I have no idea. I think the content are just the same. Maybe I like the labellings kot :P
I read in the internet that taking Multivitamins and Vitamin C could increase the milk supply, but I'm not sure how true so kena cuba la kan?
