I love this product! It is the best probiotic I've tried. I used to get stomach aches whenever I had to take an antibiotic and this product changed things. It is true that I used it almost continuously for 4 months before I was forced to take antibiotics but I noticed a (good) difference. I intend to take 2 caps a day for 3 months after my last course of prescribed medication. Here comes the WARNING though and it is meant for NON-US CUSTOMERS: YOU ARE FORECD TO PAY SHIPPING FEES AS IF iHerb sent this product in an iced, insulated package to you which DOES NOT HAPPEN! Basically you have the same shipping conditions as for any other product (including the similar in size and weight RAW Enzymes, Women(90 caps) still from Garden of Life). Still the weight used to determine shipping costs (particularly relevant for those using DHL os UPS) is 1.52 kg versus the 0.39 kg weight of RAW Enzymes! I've contacted customer service twice about this issue and I've received a standardised answer that didn't truely address my question. Disappointing!
