Oooh mama, yan talaga ang side effect ng iron supplements, napaka-bitter and metallic ang lasa! A few of us nag-complain din nito during pregnancy, it's so annoying kasi parang laging may weird taste sa mouth. Try taking it with juice (orange juice works best!) or right before meals para hindi gaano-lasa, and some of my mum friends swear na mas okay kung kinukunan ng "flush" with water agad after, marami ring nagsabi na mas tolerable pag take mo siya at bedtime na lang. But honestly, if it's really unbearable or if it's affecting your health (like hindi ka kumakain or something), mas better mag-check with your OB or doctor para sila na mag-adjust ng dosage or ibang brand na mas kaya mong kayanin!
