Magnesium for Sleep: What to Know Before You Buy
Could better sleep really come in a capsule? Before buying magnesium for sleep, check what the research can—and cannot—promise.
The quick answer
Research on magnesium supplements for insomnia is limited, and results are mixed. A popular bedtime trend is not proof that it will help you. Supplements can also cause side effects and interact with medicines; ask your pharmacist before starting one.
Try these basics tonight
Keep your bedroom dark, quiet and comfortably cool.
Use a consistent sleep and wake-up schedule.
Avoid caffeine close to bedtime and put screens away as you wind down.
Product focus: a comfortable sleep mask
If unwanted light is the problem, an adjustable sleep mask is a practical option. Look for a comfortable fit, easy cleaning and a design that does not press on your eyes. It is an optional accessory, not a treatment for insomnia.
When to ask for help
If sleep problems keep affecting your day, speak with a healthcare professional. Cognitive behavioural therapy for insomnia (CBT-I) is usually the first treatment recommended for long-term insomnia.
