For Lactose Intolerance "My 10-year-old son would get stomach cramps and diarrhea every time he tried milk. We tried Lactaid on two different occasions a few weeks apart, and both times it caused vomiting. Obviously, something in the pills does not agree with him."

For Lactose Intolerance "This is my second time trying this pill. The first was about ten years ago. Therefore, I brushed the side effects to the side and thought it was just me. This time, I took two pills, and all I can say is that I will never try them again! Maybe it’s just me, but I vomited, had diarrhea, and my stomach hurt for hours. I prayed to the porcelain queen like no other. All I wanted was a mini bar of ice cream, but after feeling so bad, I’d rather deal with the side effects from having the ice cream."

For Lactose Intolerance "The first time I took this, I experienced extreme stomach ache, believing that my body was just not used to it. A few hours later, I experienced diarrhea. I was very confused, but I used it again the next few days, and the second time, it did the same thing. The only difference was I experienced horrible vomiting, my throat was burning so bad I was in horrible pain. After doing some research about it, many people have experienced the same thing. DON’T BUY THEM, NOT WORTH IT."

For Lactose Intolerance "I have a mild lactose intolerance. I had a cheeseburger a few days ago, which usually only gives me a small stomachache, but about 15 minutes after taking this, I had a MASSIVE one. The next day, I thought that maybe it didn’t work because I chewed it. So I tried it again with some yogurt (which gives me a pretty bad stomachache but not crazy), and once again, MASSIVE stomachache. DO NOT TAKE THIS!"
