Specifications & Active Composition

Mechanism of Action & Formulation Insights

Magnesium Hydroxide is the primary active ingredient and functions through two mechanisms:

1. As a Laxative: It acts as an osmotic agent, drawing water into the intestines. This softens the stool and stimulates bowel movement within 30 minutes to 6 hours, depending on the dose and the individual.
2. As an Antacid: It neutralizes stomach acid, relieving occasional heartburn, acid indigestion, and sour stomach. Magnesium hydroxide reacts with hydrochloric acid in the stomach to form magnesium chloride and water, thereby buffering acid levels.

Because it’s a non-stimulant laxative, it tends to cause less cramping or urgency than stimulant options like senna or bisacodyl, making it a preferred choice for gentle overnight relief.

Performance & Effectiveness

Milk of Magnesia is widely regarded for:

• Reliable constipation relief: Most users experience bowel movements within 6 hours, often overnight when taken at bedtime.
• Gentle on the stomach: It is non-habit forming and less aggressive than many other laxatives.
• Dual-purpose use: Unlike most laxatives, it also addresses mild acid reflux or dyspepsia symptoms.
• Consistent formulation: The product has remained mostly unchanged for decades, which speaks to its enduring efficacy.
