Hi! Unfortunately hindi ko sure kung available ang Mama's Choice prenatal vitamins sa Mercury kasi ang Mama's Choice products na commonly nakikita ko ay yung skincare at breastfeeding line nila, hindi masyado yung vitamin supplements, pero definitely check their official website or mag-call ka sa Mama's Choice customer service nila para malaman mo kung saan exactly makikita mo yun, basta sigurado ka na authentic! A few of us moms prefer bumili directly from their online store or authorized retailers para sure na legit ang bili natin. Sana mahanap mo na!
