What Is Magnesium Hydroxide?
Magnesium hydroxide is a compound made from magnesium and water, most commonly recognised as Milk of Magnesia. It's used both as a gentle laxative and as an antacid.
You'll often find it in liquid or chewable tablet form, offering fast-acting support for digestive discomfort.
Magnesium Hydroxide vs. Other Forms of Magnesium
Compared to other types like magnesium chelate, liquid magnesium, and magnesium oil spray, magnesium hydroxide is mainly used for short-term digestive support.
While it doesn't absorb as easily, it still offers helpful results—especially for constipation and acid reflux.
So, if you're comparing options, magnesium hydroxide stands out for targeted digestive relief, rather than long-term supplementation.

How Magnesium Hydroxide Works in the Body
Magnesium hydroxide acts in two key ways: it draws water into the intestines to soften stool, and it neutralises excess stomach acid.
This makes it effective for constipation, indigestion, or occasional heartburn. It also supplies magnesium, a mineral your body uses for nerve, muscle, and cell function.
While it's not the best choice for general magnesium support, it can help correct low levels in the short term.
Top Health Benefits of Magnesium Hydroxide
Gentle Relief from Occasional Constipation
This is what magnesium hydroxide is best known for.
By drawing water into the colon, it softens stool and promotes bowel movements within a few hours. It's a reliable, non-habit-forming option when you need occasional digestive support.
Neutralises Stomach Acid and Eases Indigestion
As an antacid, magnesium hydroxide helps quickly reduce excess stomach acid. If you deal with heartburn or indigestion after meals, this can provide fast, temporary relief.

May Support Regularity
Using magnesium hydroxide from time to time may help those who struggle with irregular bowel habits. Just be sure to use it occasionally—not as a long-term fix.
Helps Restore Magnesium Levels
While not the most absorbable form, magnesium hydroxide still provides magnesium to the body.
For those with mild deficiencies, it can offer short-term support, especially if paired with other magnesium-rich foods or supplements.
Contributes to Electrolyte Balance
Magnesium is an essential electrolyte, playing a role in hydration, nerve function, and muscle control.
By maintaining normal magnesium levels, magnesium hydroxide can indirectly support these systems—especially when fluid or electrolyte loss is a concern.
Who Might Benefit from Magnesium Hydroxide Use?
Magnesium hydroxide is a good fit for those needing occasional help with constipation or digestive discomfort.
It's also a helpful option for people who want a short-term boost in magnesium but prefer to avoid pills or powders.
While athletes and active individuals may benefit from magnesium, other forms like magnesium oil spray or magnesium chelatemay be better suited for regular use.
How to Use Magnesium Hydroxide Safely and Effectively
Always follow label directions, and start with the lowest effective dose.
For adults, that usually means one to two tablespoons of the liquid form taken once a day. It can be taken with or without food.
Do not use it for more than a few days in a row unless directed by a healthcare provider.
Side Effects and Precautions
Magnesium hydroxide is safe for most people when used occasionally and as directed. Taking too much can lead to diarrhoea, dehydration, or mineral imbalances. Those with kidney issues or on medication should consult a healthcare provider before use.
