Walk into any chemist and you'll find a whole shelf of magnesium for sleep. Glycinate, citrate, powders, gummies, "night" blends. It's become the go-to fix for people who lie awake. Meditation, on the other hand, costs nothing and takes a bit of practice. So which one should you reach for?
The honest answer: they work in different ways, and for a lot of people the best result comes from understanding what each one can and can't do.
The Short Answer
If your body is low in magnesium, topping it up may help your sleep a little. If your mind is busy at night, meditation goes straight at the problem. Most people who can't sleep have the second problem, not the first.
| Magnesium | Meditation | |
|---|---|---|
| What it does | A mineral your body needs for muscles, nerves and hundreds of other jobs | Calms the stress response and gives a racing mind somewhere to rest |
| Evidence for sleep | Small studies, mixed results. Most promising in older adults and people who are low in it | Good evidence that mindfulness and relaxation practices help people fall asleep and rate their sleep better |
| How fast | Varies. Often a few weeks to notice anything | Some people feel calmer the first night; it gets easier with practice |
| Cost | Around $15 to $40 a month | Free |
| Side effects | Loose stools, stomach upset; can interact with some medicines | Rare. Occasionally brings up uncomfortable feelings |
| Best for | People with low intake, muscle cramps, or a GP's go-ahead | Busy minds, stress, worry, 3am waking |
What Magnesium Can (and Can't) Do for Sleep
Magnesium is an essential mineral. You get it from leafy greens, nuts, seeds, legumes and whole grains. It helps your muscles relax and your nervous system work properly, which is why people link it with sleep.
The research, though, is thinner than the marketing. Reviews of the studies have found only modest, low-quality evidence that supplements improve sleep, mostly in older adults. If you already eat well and your levels are fine, extra magnesium may not do much. If you're low, it may help more.
The forms you'll see, like glycinate, citrate or oxide, mostly differ in how well they're absorbed and how likely they are to upset your stomach. There isn't strong evidence that one "sleep form" beats the rest.
A few safety basics. In Australia the recommended daily intake from all sources is about 400 to 420 mg for men and 310 to 320 mg for women, and the upper limit for magnesium from supplements is 350 mg a day for adults. Too much can cause diarrhoea and cramps. People with kidney problems should avoid supplements unless their doctor says otherwise, and magnesium can interfere with some antibiotics and osteoporosis medicines. Check with your GP or pharmacist before you start, especially if you take other medication.
What About Melatonin?
People often ask about magnesium vs melatonin. They're very different. Melatonin is a hormone that tells your body it's night-time. In Australia it generally needs a prescription, although pharmacists can supply some products to people aged 55 and over. It's mainly useful for shifting your body clock, for example with jet lag, rather than for a busy mind. Talk to your GP before trying it.
What Meditation Does for Sleep
Most sleepless nights aren't about minerals. They're about a mind that won't stop and a body that's still braced for the day. Meditation works on exactly that. Slowing your breath, relaxing your muscles and giving your attention one simple thing to rest on lowers the stress response that keeps you awake.
It doesn't come in a bottle, which is both the downside and the point. It's a skill. The first few nights it might feel strange. After a week or two, many people find their body starts to recognise the routine and settle faster.
If you'd like to try it tonight, start with the 10-minute sleep meditation, the body scan for sleep or a deep sleep meditation.
Can You Use Both?
Yes, and plenty of people do. If your GP is happy for you to take magnesium, there's no conflict with meditating. Just be honest with yourself about which one is doing the work. A useful test: take a break from the supplement for a couple of weeks while you keep meditating, and see if anything changes.
Whatever you choose, the basics still matter most. A regular wake-up time, a dim last hour, less caffeine after midday and a calm routine in bed will do more than any single product.

Frequently Asked Questions
What is the best magnesium for sleep?
There's no clear winner. Glycinate is popular because it's gentle on the stomach, but the evidence for any one form is limited. Ask your pharmacist which suits you and your medicines.
When should I take magnesium for sleep?
Many people take it with dinner or in the evening. Follow the label or your pharmacist's advice, and don't go over the recommended dose.
Is meditation better than magnesium for sleep?
For stress and a busy mind, meditation targets the cause more directly. Magnesium may help if you're low in it. They aren't rivals, and you can do both.
