Best Magnesium Supplements for Sleep & Stress in the UK (2025 Guide)

More than 36% of UK adults struggle with poor sleep and rising stress levels. Instead of prescription pills, many people are turning to magnesium supplements — especially magnesium glycinate, the most bioavailable and gentle form.

But with so many options (oxide, citrate, bisglycinate, glycinate), how do you know which is right? This guide explains the science, the benefits, and highlights the best clean magnesium supplements in the UK.

Why Magnesium Matters for Sleep & Stress

Magnesium is known as the relaxation mineral. It helps calm the nervous system, regulate melatonin, and support over 300 biochemical reactions in the body. Deficiency is widespread in Britain — especially in people under stress.

😴 Improves sleep quality
🧠 Calms anxiety & racing thoughts
💪 Relaxes muscles & prevents cramps
⚡ Boosts energy by day, relaxes at night

Different Forms of Magnesium

Magnesium Oxide — cheap, poorly absorbed, often causes stomach upset
Magnesium Citrate — better absorbed, but can have a laxative effect
Magnesium Glycinate (Bisglycinate) — gold standard for sleep and stress, highly absorbable and gentle
Magnesium Malate — more for energy & muscle recovery

👉 For sleep, stress, and nervous system health, **Magnesium Glycinate** is the clear winner.
