There is no direct evidence suggesting that glutamine causes constipation. Glutamine is an amino acid that plays a crucial role in various bodily functions, including supporting the immune system and maintaining the health of the gastrointestinal tract.
In fact, some studies have suggested that glutamine might have a positive impact on gastrointestinal health and could potentially alleviate symptoms of conditions like inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS).
However, it is essential to remember that individual responses to supplements can vary, and some people might experience side effects or adverse reactions, even to generally well-tolerated substances like glutamine.
If you are concerned about constipation or any other gastrointestinal issues, it's best to consult with a healthcare professional who can provide personalized advice based on your medical history and current health status.
