Hi mama! I really can't say if that specific brand is safe or right for you, kailangan mo talaga tanungin ang doctor mo or OB mo about that, lalo na if you're pregnant or breastfeeding, okay? They know your health best and pwede ka nila i-guide sa tamang calcium para sa'yo. A few of us mums always check with our doctors first before trying any new supplement, so sige na, message your doc agad!
