I took Lactaid Fast Act three times and got violently ill with vomiting and diarrhea that lasted for three hours each time. (I did not realize it was the lactaid making me sick until the third time I took it because I don't have a problem with any of their other products.) I reported the problem to Lactaid and they did refund my purchase. However, the associate told me that because I experienced diarrhea they were going to consider it a bought of lactose intolerance! I tried to explain that my experiences were much worse than my normal lactose intolerance, but she just kept reading the same statement. Very sad the company would ignore a potential allergic reaction or lot problem.
No, I would not recommend this product
