I have used AB products for about 5 years. I absolutely love them. My pup had allergies so freaking bad it almost looked like she had mange. Poor sad baby. I used the allergy test to see what to start cutting out. I emailed them pictures of my poor pup and asked where to start. They very kindly suggested using Yeast Beast Kit and Leaky Gut Kit (both at half doses) in rotation until it was under control. I wasnt sure how they yeast beast was going to help since allergies were the issue but bc the skin allergies had been so bad she had an extensive case of skin yeast that almost made it impossible to heal. I hadn't realized that. After several cycles back and forth she is almost completely healed. I am switching over to this kit now that there are no signs left of yeast. Thanks a million AB!
