Dose: 5–10 g

Strong

Magnesium citrate acts as an osmotic laxative, drawing water into the large intestine to soften stool and stimulate peristalsis. The citrate anion directly activates smooth muscle contraction, making this form specifically effective for constipation-type bowel irregularity.

Dose: 500–2000 mg
