I have used BIO X4 for the last three months because I was irregular due to my colitis flare-ups and the pockets I have in my colon (colon cancer runs in my family tree). So there has been many a time at work, special occasions, and just being out that has been uncomfortable for me, as I never knew when I would have a flare-up. Since taking BIO X4 I have become regular, no cramping or feeling of nausea. It has been a pleasure to have part of my life back.
Bottom Line: Yes, I would recommend this to a friend
