In a 24-hour society that prioritises connectivity and productivity, it\u2019s no wonder so many people struggle to achieve regular restful sleep<\/a>. It\u2019s thought around two-thirds of adults in the western world fail to get the recommended eight hours a night \u2013 with women also rating their sleep quality as lower and reporting more fluctuations in sleep quality than men. Decades of research<\/a> confirm the importance of sleep for every aspect of health. This doesn\u2019t makesleeping any easier, though. Andwhere there is struggle, there are aggressively marketed \u2018solutions\u2019 \u2013 magnesium<\/a> supps being the latest.<\/p>\n

Meet the expert:<\/strong> Dr Sammie Gill<\/a> is a registered dietitian specialising in nutritional immunology<\/p>\n

Magnesium is an essential mineral involved in more than 300 bodily processes. Plant-based food sources include leafy green vegetables<\/a>, nuts,<\/a> seeds, legumes and whole grains. Animal products also contain magnesium, but in smaller amounts. In the UK, the daily magnesium target is 270mg for women, but the most recent National Diet and Nutrition Survey<\/a> data found 17% of UK adults aged 19 to 64 have magnesium intakes well below the recommended level \u2013 and a review in the journal Nutrients<\/a> found deficiency was more commonly noted in women than in men. <\/p>\n

It\u2019s thought that magnesium can support sleep by: influencing levels of neurotransmitters that switch the brain \u2018off\u2019, such as gamma-aminobutyric acid (GABA); supporting the production of hormones involved in the sleep-wake cycle, such as melatonin; dampening the stress<\/a> response and lowering stress hormones, such as cortisol; and acting as a timekeeper by helping to regulate the internal \u2018clocks\u2019 of every cell in the body.<\/p>\n

The combined effect of these mechanisms is believed to calm the central nervous system (brain and spinal cord) and decrease feelings of anxiety<\/a> while promoting muscle relaxation and supporting maintenance of normal sleep-wake cycles. But while observational studies<\/a> indicate sleep-promoting effects, limited gold-standard trials report mixed results.<\/p>\n

Supplementation\u2019s effectiveness can also depend on the type of magnesium used. It needs to be able to cross the blood-brain barrier in a form usable by brain cells and some kinds are more brain bioavailable than others. One promising type is magnesium threonate \u2013 a recent trial<\/a> showed daily supplementation for three weeks improved sleep quality and daytime alertness in people with self-reported sleep problems.<\/p>\n

So, should everyone turn to magnesium for sleep? No. If you eat a diverse, plant-first diet and consider yourself a healthy sleeper, magnesium supplementation is unnecessary. If you struggle to sleep despite eating well, try (free!) sleep strategies backed by more robust science first, focusing on regularity, timing, temperature and lighting.<\/p>\n

That said, if you suspect you\u2019re not getting enough magnesium from your diet \u2013 or tests of your nutrient levels reveal this to be the case \u2013 and you also have difficulty sleeping, it\u2019s worth giving it a shot.<\/p>\n

But remember, health is individual and multifactorial; just because it worked for your favourite wellness TikTok-er doesn\u2019t mean the same is guaranteed for you \u2013 and there are risks involved with over-consuming magnesium, too. Consult your doctor if you\u2019re taking other medications or have an existing health condition; shop smartly (see my picks below) and measure success to see if you get ROI. Record your baseline sleep, then try one month with magnesium followed by a month without.<\/p>\n
