Are you struggling to fall asleep at night? Sleepless nights can be frustrating, leading many people to search for solutions. One option that has gained attention is taking magnesium for sleep. But does it really work? Let’s explore the benefits and considerations of using magnesium as a sleep aid.

What is magnesium?

Magnesium is a mineral that is found in a variety of foods and dietary supplements. It plays a crucial role in the body, supporting functions such as protein production, bone and DNA formation, blood sugar and pressure regulation, and the proper functioning of muscles, nerves, and the cardiovascular system.

Is magnesium good for sleep?

While the science on whether magnesium improves sleep length and quality is still mixed, it is believed to have potential benefits. Some studies suggest that magnesium may act on certain receptors in the brain, helping to calm brain cell activity and promote sleep. It is also thought to affect levels of melatonin, the hormone responsible for regulating our sleep-wake cycle.

Additionally, magnesium has muscle relaxant properties, which may help alleviate symptoms of restless legs syndrome in some individuals. However, it’s important to consult a doctor if you suspect you have this condition and need a proper diagnosis.

How much magnesium should you take?

The optimal dosage of magnesium for sleep can vary depending on individual health conditions and medications. It is recommended to consult with a healthcare professional to determine the appropriate dosage for you. Generally, it is advised to obtain magnesium through a balanced diet rather than relying solely on supplements.

If you do choose to take a magnesium supplement, it is suggested to opt for magnesium glycinate or magnesium citrate, at a dosage of around 200 milligrams. Avoid magnesium oxide, as it may have a stool-softening effect. Take the supplement approximately 30 minutes before bedtime for the best potential sleep benefits.

Side effects and precautions

While magnesium is generally safe for most people when taken as directed, there are potential side effects to be aware of. These can include drowsiness or fatigue during the day, muscle weakness, nausea, vomiting, skin flushing, or diarrhea. In rare cases, high levels of magnesium in the blood can lead to dangerous heart rhythm abnormalities, including cardiac arrest.

It’s also important to note that magnesium can be overdosed. Individuals with kidney disease or certain medical conditions may have difficulty eliminating excess magnesium from their bodies, which can lead to elevated levels. Therefore, it is always wise to follow the recommended dosage and consult with a healthcare professional if you have any concerns.


Here are some frequently asked questions about using magnesium for sleep:

Q: Can you overdose on magnesium?
A: Yes, it is possible to overdose on magnesium, especially for individuals with kidney disease or certain medical conditions. It’s important to follow the recommended dosage and seek medical advice if needed.

Q: Is it okay to take magnesium every night?
A: It is generally not recommended to rely on magnesium supplements every night for sleep. Insomnia can be a symptom of an underlying sleep disorder or other health conditions. It is best to seek a comprehensive evaluation from a healthcare professional to identify the root cause and receive appropriate treatment.

Q: Are there foods high in magnesium that can help with sleep?
A: Yes, there are several foods that are rich in magnesium and can potentially aid in sleep. These include fish, soy and soy milk, legumes, fortified breakfast cereals, whole grains, green leafy vegetables, pumpkin and chia seeds, almonds, and cashews.


While the scientific evidence on the effectiveness of magnesium for sleep is not definitive, it may still be worth considering as part of a comprehensive approach to improving sleep. Remember to consult with a healthcare professional for personalized advice, especially if you have underlying health conditions or are taking medications.
