Between normal formula so to speak and the Gold ones? I know they have extra omega 3 but other that????

I'm currently BF exclusively and am trying to express enough also for when i go back to work cause I would like to still BF then but my supply just doesn't seem to be increasing with feeding and expressing so am considering my options for when I do go back (in 3 wks)

I noticed one in the supermarket by somthing organics??? Has anyone used this one??
