Okay lang yan, mommy! Calcium carbonate is safe to take anytime of day, but marami sa amin prefer taking it with food para mas better ang absorption and para walang upset stomach, ang hapon is perfectly fine, lalo na kung kumain ka na ng lunch. Just make sure you're consistent with your timing so hindi ka makakalimutan, at if you have any concerns about the amount you're taking or kung may side effects ka, better check with your OB para sigurado lang. Congrats sa pregnancy!
