                                Reports show that consuming large single doses of specific amino acids, such as arginine, can lead to significant gastrointestinal distress, including diarrhea. While a balanced diet is the body's primary source, supplemental amino acids, when taken in excess, can overwhelm the digestive system. This article uncovers the science behind why amino acids can cause diarrhea and offers practical advice on how to avoid it.
