What are the most common side effects when supplemental magnesium intake exceeds the Upper Limit (UL)?
Answer
Gastrointestinal distress like nausea, abdominal cramping, and diarrhea
When the intake of supplemental magnesium surpasses the established Upper Limit (UL) of 350 mg per day, the body's ability to process this load efficiently is overwhelmed, resulting primarily in acute gastrointestinal disturbances. The most commonly reported uncomfortable side effects resulting from this excess include nausea, painful abdominal cramping, and diarrhea. These symptoms are a direct indicator that the threshold for tolerance to supplemental doses has been breached, necessitating an immediate reduction in the amount taken.
