Magnesium plays a crucial role in over 300 biochemical reactions in the human body, from muscle function and nerve signaling to energy production and bone health. Yet, many people in the UK aren’t getting enough of this essential mineral.

Magnesium deficiency is often called the “invisible deficiency” because the symptoms can be subtle and easily overlooked. In this guide, we’ll walk you through the 11 most common warning signs of magnesium deficiency—and what you can do to correct it.

1. Muscle Cramps and Spasms

Frequent muscle twitches, cramps, or spasms—especially in the legs—may be your body’s way of asking for more magnesium. This mineral helps regulate muscle contractions, and low levels can lead to involuntary muscle movements.

2. Chronic Fatigue or Low Energy

If you’re constantly tired despite getting enough rest, magnesium could be the missing piece. Magnesium is essential for producing ATP, the energy currency of your cells. Without enough, fatigue and weakness can become daily struggles.

3. Sleep Issues or Insomnia

Struggling to fall asleep or stay asleep? Magnesium promotes relaxation by regulating neurotransmitters like GABA, which calm the brain. Low magnesium levels can contribute to restless sleep and even insomnia.

4. Headaches or Migraines

Magnesium deficiency is linked to an increased risk of migraines. It helps regulate blood flow to the brain and reduces nerve overactivity—both important factors in preventing headaches.

5. Anxiety and Mood Swings

Magnesium supports mental well-being by balancing brain chemicals and reducing inflammation. Deficiency has been associated with increased anxiety, irritability, and even symptoms of depression.

6. High Blood Pressure

Magnesium helps relax blood vessels, improving circulation and reducing blood pressure. Chronically low levels may contribute to hypertension—especially when combined with a poor diet or stress.

7. Numbness or Tingling

A lack of magnesium can affect your nervous system, leading to unusual sensations like numbness, tingling, or pins and needles, particularly in the hands and feet.

8. Irregular Heartbeat

Also known as arrhythmia, an irregular heartbeat can sometimes be linked to low magnesium levels. Magnesium helps regulate heart rhythm and supports healthy cardiac function.

9. Osteopenia or Weak Bones

Magnesium is critical for bone health. It supports calcium absorption and works alongside vitamin D. Without enough magnesium, bones may become weaker over time—raising the risk of fractures.

10. PMS Symptoms in Women

Magnesium has been shown to reduce symptoms of premenstrual syndrome (PMS), such as bloating, cramps, mood swings, and breast tenderness. Deficiency may intensify these monthly discomforts.

11. Poor Blood Sugar Control

Magnesium plays a role in regulating insulin sensitivity and blood sugar levels. Deficiency may contribute to insulin resistance and is linked to a higher risk of type 2 diabetes.

What Causes Magnesium Deficiency?

Several factors may contribute to low magnesium levels, including:

• Processed food diets low in whole grains and leafy greens
• Excess alcohol or caffeine consumption
• Gastrointestinal disorders (e.g., Crohn’s, IBS)
• Certain medications (e.g., diuretics, antibiotics)
• Chronic stress or intense exercise

How to Restore Magnesium Levels Naturally

1. Eat Magnesium-Rich Foods: Include dark leafy greens, nuts, seeds, whole grains, and legumes.
2. Reduce Stress and Caffeine: These can deplete magnesium over time.
3. Supplement Wisely: If diet alone isn’t enough, a high-quality supplement can help.
