Magnesium has become one of the most heavily marketed supplements out there, promising to fix your sleep overnight. So in this episode I went through what the research actually says. The honest answer is that the evidence is pretty thin. A lot of it comes from small studies, often funded by companies selling the product, and frequently without a proper placebo group. There is one small trial in elderly people with insomnia that gets quoted a lot, and it showed only modest improvement in a low quality study. When you pull together the better evidence, magnesium might nudge sleep very slightly in some people, but the effect is small and the certainty is low. A chunk of what people feel when they take it is likely the placebo effect, and I talk through why that matters so much with sleep specifically. There is one group it can genuinely help though, and that is people who are actually deficient. Certain people are more likely to run low, including those with poorly controlled diabetes, gut conditions that affect absorption, heavy drinkers, and people on certain long term medications. A standard blood test can be misleading here too, since less than one percent of your body's magnesium is in your blood. For someone eating a reasonably varied diet, true deficiency is not that common, since magnesium is already in foods like leafy greens, nuts, seeds, beans and whole grains. The bigger question I wanted to get into is why you are not sleeping properly in the first place, because a supplement can only ever paper over a cause. I cover the real drivers I see time and again, caffeine too late in the day, alcohol quietly wrecking your deep sleep, an inconsistent wake time, a bedroom that is too warm or bright, and a stressed mind that will not switch off. I also share a bit of my own experience with this during a rough patch with George's sleep, and what actually helped me get through it. Then I walk through the free changes that genuinely shift sleep long term, anchoring your wake time every day, getting outside in daylight soon after waking, cutting caffeine off by midday, keeping alcohol away from bedtime, keeping your room cool and dark, and getting your phone out of the bedroom. The full list of research references I mention is in the description of the YouTube version of this video.
