What Is Magnesium and Why Is It Important?

Magnesium is a mineral found in your bones, muscles, and brain. It plays a part in over 300 biological processes that keep your body running smoothly. From regulating blood pressure to supporting restful sleep, magnesium helps you feel balanced and energised.

Despite its importance, many people in the UK don’t get enough magnesium through diet alone. This is where supplements come in.

Top Magnesium Benefits

Let’s look at some of the biggest reasons people take magnesium and how it can improve your daily life:

  • Better Sleep: Magnesium helps calm the nervous system, making it easier to fall and stay asleep.
  • Reduced Stress and Anxiety: It supports the production of calming brain chemicals, helping you feel more relaxed.
  • Muscle Health: Prevents cramps, supports muscle recovery, and reduces soreness after exercise.
  • Heart Support: Helps regulate blood pressure and supports a steady heartbeat.
  • Improved Energy Levels: Magnesium helps convert food into energy, reducing fatigue.
  • Stronger Bones: Works with calcium and vitamin D to keep bones healthy.
  • Better Digestion: Helps with bowel regularity and can relieve occasional constipation.

Signs You Might Be Low in Magnesium

It’s surprisingly easy to be magnesium-deficient, especially with today’s processed diets. Here are some common signs:

  • Muscle cramps or twitching
  • Fatigue or low energy
  • Difficulty sleeping
  • Increased anxiety or irritability
  • Frequent headaches or migraines
  • Poor digestion or constipation

If you’re experiencing any of these symptoms, it might be worth speaking to your GP or considering a supplement.

Best Sources of Magnesium in the UK Diet

While supplements are popular, you can also get magnesium from certain foods. Here are some great dietary sources:

  • Dark leafy greens like spinach and kale
  • Whole grains such as brown rice and oats
  • Nuts and seeds (especially almonds and pumpkin seeds)
  • Legumes like lentils and chickpeas
  • Dark chocolate (in moderation!)

Unfortunately, UK soil has become depleted of magnesium over time, which can make it harder to get enough through diet alone — another reason why supplements are popular.

Popular Types of Magnesium Supplements

Not all magnesium supplements are the same. Here are some of the most common types available in the UK, and what they’re good for:

  • Magnesium Glycinate: Great for sleep and anxiety, gentle on the stomach
  • Magnesium Citrate: Helps with constipation and digestion
  • Magnesium Malate: Supports energy and muscle recovery
  • Magnesium Threonate: Best for brain and cognitive function
  • Magnesium Oxide: Affordable, but not as well absorbed

Always check the label and aim for a well-absorbed form. Talk to your pharmacist or GP if unsure.

Are Magnesium Supplements Safe?

Magnesium is safe for most people when taken in recommended amounts. Side effects are rare but can include mild diarrhoea, especially if you take too much at once.

The NHS recommends not exceeding 400mg per day of magnesium from supplements, unless advised by a doctor.
