Yes, he was generally not been a big fan of probiotics in general but did speak favorably about phages. Some forum members used that particular one with good results so I decided to give it a try!interesting, I got off all probiotics, Im still new to Ray Peat, but I am under the impression that he is anti-probiotics...But if it works as a solution occasionally (as in, not taking it daily), perhaps its ok...Anyone know more about Dr. Peat's view on Probiotics as a solution for constipation?
