Hi! My vet put my three girls on Healx Booster to, hopefully, improve their immune sysytems. Penelope has been on antibiotics three times and the two lil girls were on them for 2 & 3 weeks while in quarantine. They all got a clean bill of health but are on an antihistamine twice a day to see if allergies are at play & the vet ordered the Booster which just came in today. Information that I was given with it says that it has antibacterial, antiviral, anti fungal & anti protozoan properties & boosts the immune system. Sounds like it has vitamins or pre-cursors to vitamins E, A, K and others.Just curious if anyone else has used it and what your results were. Thanks in advance!
