Magnesium Deficiency: Signs You Might Be Missing

An estimated 70% of UK adults may not be meeting their daily magnesium intake. Here is how to recognise the signs and what to do about it.

Magnesium is involved in over 300 enzymatic reactions in the body, yet it remains one of the most overlooked minerals. From energy production to muscle function and sleep regulation, this essential mineral touches nearly every system in your body.

So what happens when you're not getting enough? The signs of magnesium deficiency can be subtle and easy to dismiss. Common indicators include:

Muscle cramps and twitches — especially in the legs at night, often dismissed as just tiredness or dehydration.

Fatigue and low energy — magnesium plays a central role in ATP (energy) production. When levels are low, so is your energy.

Poor sleep quality — magnesium helps regulate GABA, the neurotransmitter that promotes relaxation and sleep. Low levels are linked to restless nights.

Headaches and migraines — research suggests people who experience frequent migraines often have lower magnesium levels.

Anxiety and mood changes — magnesium helps regulate the stress response. Deficiency can amplify feelings of anxiety and irritability.

Why are so many people deficient? Modern diets high in processed foods are low in magnesium-rich whole foods like dark leafy greens, nuts, seeds, and wholegrains. Stress and intensive exercise can also deplete magnesium faster.
