If you struggle to switch off at night, magnesium is one of the most talked-about natural options — and for good reason. Here’s how it works and how to use it well.
How magnesium supports sleep
Magnesium helps regulate the nervous system and supports GABA, a calming neurotransmitter that helps your brain wind down. It also plays a role in muscle relaxation, which is why a deficiency can leave you feeling tense and restless.
Many women are low in magnesium without realising, especially during busy or stressful periods — exactly when sleep tends to suffer.
The best form for sleep
Magnesium glycinate is the standout for rest, thanks to the calming glycine it’s bound to. It’s the focus of our Simple Magnesium. For the full comparison, see glycinate vs citrate.
Building a wind-down routine
Take magnesium in the evening, dim the lights, and step away from screens 30–60 minutes before bed. Pair it with ashwagandha if stress is keeping you up — our Stress Less Bundle combines both.
