What are the side effects of L-carnosine?

L-Carnosine is generally considered a safe supplement for short-term use, but it can cause some side effects, which are usually mild. Common side effects mainly involve gastrointestinal discomfort, such as nausea, vomiting, diarrhea, or stomach cramps; taking it with food may help relieve these symptoms. Other less common mild reactions include rash, dry mouth, changes in appetite, and fatigue. However, it's important to note that L-carnosine has the potential to lower blood pressure, so people with low blood pressure or those taking antihypertensive medication should use it with caution to avoid lowering their blood pressure too much. Additionally, it may affect blood sugar levels; people with diabetes should consult their doctor before use and are advised to stop taking it at least two weeks before any scheduled surgery to avoid interfering with blood sugar control during and after the procedure. It is generally not recommended for pregnant or breastfeeding women because its safety has not been fully established. It is best to consult a healthcare professional before starting L-carnosine or any new supplement to ensure it is suitable for your individual health condition.
