Useful item to keep in the cupboard for stomach upsets

Milk of Magnesia has been a surprisingly helpful addition to managing my Irritable Bowel Syndrome (IBS) symptoms, especially during those challenging periods of constipation. While it’s not a cure-all for IBS (since the condition varies so much between individuals), I’ve found it to be an effective and gentle remedy when used occasionally.

One of the things I appreciate most is how quickly it works. Within a few hours, I notice relief without the cramping or urgency that some harsher laxatives can cause. The liquid form is easy to take, and though it has a chalky taste, it’s not unpleasant. For anyone who struggles with IBS-related constipation, this might just be a lifesaver on tough days.

What I love about Milk of Magnesia is its simplicity—it's just magnesium hydroxide, which means no complicated or artificial ingredients to irritate my sensitive system. Plus, it’s affordable and widely available, which is always a bonus.

That said, I use it sparingly and only when I really need it. Overuse could lead to dependency or upset the delicate balance of my gut. As with any remedy, it's a good idea to consult with a doctor, especially if you’re using it regularly or have more complex IBS symptoms.

Overall, Milk of Magnesia has been a reliable "go-to" for me as part of my IBS management toolkit. It’s like a gentle nudge for my digestive system, helping me feel more comfortable and back to normal. I’d recommend it to anyone with IBS, particularly those who experience occasional constipation, as long as it’s used responsibly.

How it works:

Milk of Magnesia, primarily composed of magnesium hydroxide (Mg(OH)₂) it works by two primary mechanisms depending on its use: as an antacid for acid reflux or a laxative for constipation.

Milk of Magnesia neutralizes stomach acid through a chemical reaction. When magnesium hydroxide comes into contact with hydrochloric acid (HCl) in the stomach, it undergoes a neutralization reaction.This reaction produces magnesium chloride (MgCl₂), a salt, and water. The process reduces acidity in the stomach, relieving symptoms of heartburn, indigestion, or acid reflux.
Unlike some other antacids, it doesn’t produce carbon dioxide (CO₂), so there's no burping or bloating from gas release.
As a Laxative
Milk of Magnesia acts as an osmotic laxative in the intestines. Magnesium hydroxide is poorly absorbed in the intestines. Its presence creates an osmotic gradient, drawing water into the intestinal lumen (the hollow part of the intestine) from surrounding tissues.
The added water softens stool and increases its volume, stimulating bowel movements by enhancing peristalsis (the wave-like contractions of the intestines).

In this case, magnesium ions (Mg²⁺) also plays a role by interacting with the intestinal walls to promote muscle relaxation and encourage natural bowel movement.

Key Points about its Use
- Onset of Action:
- As an antacid: Works quickly, often within minutes.
- As a laxative: Takes 6–8 hours to produce a bowel movement.
- Safety: Magnesium hydroxide doesn’t irritate the digestive tract, making it a gentler option compared to stimulant laxatives. However, excessive use can lead to dehydration, electrolyte imbalances, or dependency for bowel movements.

So helpful but too expensive

I have had operations & advised to take Magnesium hydroxide regularly on prescription. Alternatives are not an option as I'm intolerant to maize which is in other medications. It is an excellent product while it has few additives. This is not generally available now so I have had to buy it. It is now an exorbitant price, going beyond my & most people's means.Read full review
