What Is Magnesium?

Magnesium is involved in many processes such as protein synthesis, muscle and nerve function, blood sugar control and blood pressure regulation (1, 2).

It is also needed to make your DNA and a type of antioxidant called glutathione.

As an adult, you need around 310 – 420mg of magnesium each day (3 ). What you need will change with age, sex, pregnancy and lactation.

Examples of foods which are high in magnesium are almonds, spinach, cashews and cereals (4 ).

How Does Magnesium Help Constipation?

Your doctor may advise you to take magnesium-based laxatives for constipation relief.

Magnesium is often the main active ingredient in laxatives because it has an osmotic effect on your bowel. This means that they draw in water to the large bowel, helping you pass stools (5 ).

Magnesium can also stimulate your gut to move stools along (5 ).

Can Magnesium Laxatives Cause Diarrhoea?

Due to their osmotic affect on your bowel, magnesium supplements can cause diarrhoea (5 ).

Always monitor your symptoms and if you start getting loose stools, discontinue or reduce your supplement.
