Yes, magnesium glycinate can still cause loose stools and cramping, even though it is usually gentler on the stomach than other magnesium forms.
Possible reasons:
Increased sensitivity to magnesium
Taking it on an empty stomach
Recent dietary changes, viral illness, or other supplements/medications
The magnesium may have relieved your usual constipation and temporarily overshot into loose stools
To reduce symptoms without changing the supplement:
Take it with or after a meal, preferably dinner.
Stay well hydrated.
Avoid taking it together with large amounts of caffeine or other supplements that may upset the stomach.
Consider splitting the dose further (if practical and approved by the product instructions).
If the loose stools occurred only once or twice and have settled, it is usually not concerning. However, if diarrhea persists, becomes severe, is associated with blood, fever, weight loss, or signs of dehydration, you should consult a healthcare professional for evaluation.
