Cathy McGuire knows all about psoriasis: she developed psoriasis when she was just 16. After 25 years of trying countless creams and treatments—and enduring stares and comments from strangers—she finally stumbled across a probiotic therapy that helped clear her skin. McGuire has written a book about her experience, entitled Psoriasis Coach, in which she recounts her years of struggle with the disease. She provides valuable advice and describes how she discovered that treating her immune system with the probiotic Bio-K+ proved highly effective in ridding of her of the disease once and for all. Many people become so frustrated and discouraged after repeated futile attempts to treat their psoriasis that they resign themselves to a lifetime of suffering. McGuire wrote Psoriasis Coach to let them know it doesn't have to be that way: "I hope that describing my own experience will inspire others to try probiotics to see if this simple treatment is effective for them".
