You shouldn't take pro-biotics when on anti-biotics as the anti-biotics will only kill off the pro-biotics So start the pro-biotics after the anti-biotics

Prevention is always better than cure in my books, Fast-Tract is pure pro-biotic and more potent than In-Liven and more easy to take too, tastes better. Start with Fast Tract, I should have said that before! Der! Inner Health only has a couple of strains of pro-biotic, In-Liven and Fast-Tract are far superior and also organic.
