Magnesium laxatives are a type of over-the-counter medication used to relieve constipation. These products contain magnesium, a natural mineral that helps to stimulate bowel movements by relaxing the muscles in the digestive tract. Magnesium laxatives come in various forms, including tablets, powders, and liquids, and can be taken orally or rectally. They are generally safe to use and can provide fast relief for those experiencing constipation. However, it is important to follow the recommended dosage instructions and consult with a healthcare provider if symptoms persist or worsen.

Frequently Asked Questions (FAQs)

1. Why does magnesium make you poop more?

Stool softener: Magnesium draws water into the intestines, working as an osmotic laxative. This increase in water stimulates bowel motion, or motility. It also softens and increases the size of the stool. This prompts a bowel movement and helps to make stools easier to pass.

2. Which magnesium works as a laxative?

Magnesium citrate is a saline laxative that is thought to work by increasing fluid in the small intestine. It usually results in a bowel movement within 30 minutes to 3 hours.

3. How much magnesium should I take for a laxative?

One magnesium pill of 350 mg per day of magnesium supplement is felt safe for healthy adults. Some individuals see better bowel movements with 200-500 mg of Magnesium gluconate, oxide or citrate in the morning and evening. The dose for magnesium is individual, so begin low and increase the dosage as needed.

4. How long does it take for magnesium to make you go poop?

After taking magnesium citrate for constipation relief, you should expect the laxative effect to begin in 1 to 4 hours. Contact your doctor if you notice side effects or don't experience a bowel movement. Your constipation may be a sign of a more serious underlying health condition.
