You may experience symptoms of bloating, flatulence (gas), abdominal pain, constipation or diarrhea in the first few days of probiotic therapy. These symptoms occur as your digestive system re-balances in favor of the good bacteria. The symptoms should subside after a few days. However, if they persist, then you can always reduce your dosage and ramp back up slowly. If You’re Looking for a Natural Way to Support Weight Loss and Maintain a Healthy Balanced Gut, Belly Buster Probiotic Supplement is Safe, Effective, and Convenient. Like most of Dr. Fortino’s medical weight loss products and supplements Belly Buster Daily Probiotic Supplement works as an independent supplement or in conjunction with our medical weight loss programs.
