I just got back from my dentist. She gave me another probiotic. It called Phytocare Functional Foods Replete with glutamine. Made in Australia. I think only practitioner can dispense it. I need to take it 1 teaspoon mixed with 1 tablespoon of Perm A vite Powder (this one is made in US)in room temperature water three times a day, half hour before each meal.
