Wa'alaikum assalam! Aku amik Calcium Lactate masa breastfeed dulu sebab paediatricianku suggest, tapi a few of my mum friends swear by Calcium Citrate sebab easier on the stomach, macam Blackmores or local brands pun ada. Best thing is to check with your doctor or gynae dulu sebab depend on your dietary intake and health condition, then they can recommend which one suits you best, tau!
