Im a first time mom so I can't really say if it increased my milk supply cause I cant compare it to anything and I dont pump much . I will say I notice my breast are alot fuller when I drink gatorade .
I naturally usually have a really good supply. Things I do to help establish my supply though are drink loads of water, drink at least 1 Gatorade a day, take 2 brewers yeast tabs a day, and take 2 fenugreek twice a day. I do this for 1-2 weeks and then I get a pretty solid 6-7 oz every 3 oz.
