Hi mama! Honestly, I haven't tried SKJN collagen during pregnancy kaya hindi ako makakapagsabi ng sure, yun pang kailangan i-check talaga ng doctor mo dahil bawat pregnancy ay different and some ingredients in supplements can be tricky during that time. A few of my mum friends said they stuck lang with prenatal vitamins lang during pregnancy para safe, then nag-collagen sila after. Better safe than sorry talaga, kaya best ask your OB-GYN muna before taking any new supplements, okay?
