We do not use Abbot products, but we are now being told his Nutricia Phenylade GMP Ready is on back order with no date for when it will not be. Due to everyone not getting their Abbott products it is not causing a huge constraint on everyone else including us. We have been trying Cambrooke Glyactin since we can’t get Phenylade and our son hates it. Which is causing him not to get the milk he needs and making his levels higher than they should be.
