Mineral Deficiency, Anxiety & Gut Health: Why Magnesium Matters

Did you know that up to 80% of people may have a mineral deficiency — particularly magnesium? This powerhouse nutrient is behind over 300 essential processes in the body, from muscle function to brain health, gut balance to energy production. In fact, it even regulates other key minerals like sodium, potassium, and calcium, while supporting glutathione — your body’s master antioxidant.

When magnesium levels are low, you feel it. Fatigue, restless nights, anxious thoughts, and gut discomfort can all be linked to this common mineral deficiency.

What happens when your body runs low?

Research shows that magnesium deficiency disrupts the microbiome — the community of bacteria in your gut. In studies on mice, those on low-magnesium diets not only had poor gut diversity but also displayed behaviours linked to depression in humans.

Low magnesium leads to:

• Reduced beneficial bacteria

• Increased inflammation

• Poor gut health and lower mood

And it doesn’t stop there. Signs of a mineral deficiency may include:

• Leg cramps and restless legs

• Insomnia and poor sleep

• Anxiety, irritability, restlessness

• Fatigue and low energy

Magnesium is also crucial for healthy levels of GABA, the calming neurotransmitter. Without enough, your nervous system stays on edge.

What causes mineral deficiency?

Magnesium shortfalls are more common than you think. Here’s why:

• Soil depletion — modern farming strips minerals from our food supply

• Digestive issues — conditions like leaky gut, IBD, or SIBO reduce absorption

• Medication use — some drugs interfere with gut health and nutrient uptake

• Stress — high stress depletes magnesium rapidly

• Genetics — some people simply absorb it less efficiently

How to raise your magnesium levels naturally

The best sources of magnesium-rich foods include:

• Dark leafy greens

• Nuts and seeds

• Lentils and other legumes

• Whole grains

• Dark chocolate (75%+ cacao)
