Hay, honestly I've tried both kaya depende talaga sa budget and kung ano ang effective sa'yo, a few of us sa mommy group namin, some swear by Omegabloc dahil affordable and okay naman ang results, while iba naman prefer ATC kasi mas mataas ang dosage. I started taking fish oil around second trimester ng pregnancy ko kasi sabi ng OB ko importante para sa baby's brain development, pero maraming mommies din na nagsimula lang after birth for lactation and overall health, best ask your doctor kung kelan mo specifically dapat istart based sa pregnancy or health status mo!
