We've been hit with an awful bug and have been on antibiotics. They are wreaking havoc on our guts. Usually we include Udo's probiotics or Culturelle to prevent from the tummy upset, but I can't find anything like that here. Does anyone know where I can purchase good probiotics? The kids prefer the powdered versions (capsules, sachets) so they can just mix it into yogurt and eat it. Any tips would be wonderful. Thank you!
