Aww mama, I feel you, ang hirap ng low supply, nakaka-stress talaga! Honestly, a few of us tried different multivitamins and ang common ones na nag-help sa supply ay yung may malaking iron, calcium, at B vitamins, pero really, best is to check with your OB or pediatrician kung ano ang best fit para sa'yo and your milk production kasi bawat mama is different talaga. Besides supplements though, make sure you're drinking tons of water, eating enough (especially protein), and nursing frequently, I swear that's what really boosted supply ko more than anything, plus my mum friends kept saying rest din is important kaya don't stress yourself too much mama, you're doing your best na!
