Struggling with sleep despite good habits led one person to try magnesium supplements, resulting in noticeable improvements in restfulness and relaxation. Experts say magnesium may benefit those having trouble winding down, particularly amid stress or aging.
- Magnesium may improve sleep efficiency and reduce insomnia symptoms.
- Types like magnesium glycinate are preferred for sleep with fewer side effects.
- Consult a doctor if you have kidney problems or take certain drugs.
What happened
After struggling for months with falling asleep despite maintaining good sleep hygiene such as consistent bedtimes, a cool room, and screen avoidance, a person sought professional advice. Sleep specialists recommended attempting magnesium supplementation alongside further testing for conditions like sleep apnea.
Clinical psychologist Daniella Marchetti and sleep expert Likhita Shaik agree magnesium may help people with trouble relaxing, muscle tension, or stress-related restlessness. Various types of magnesium supplements exist, each with different absorption rates and side effect profiles that influence their suitability for improving sleep.
Why it feels good
Magnesium influences sleep by increasing melatonin, a key hormone regulating the sleep-wake cycle, and reducing cortisol, a stress hormone that can disrupt rest. Studies from 2025 indicate magnesium biglycinate can modestly improve insomnia severity, especially for those who don’t consume sufficient magnesium naturally through diet.
Choosing the right supplement form also matters. Magnesium glycinate is noted for good absorption and minimal gastrointestinal symptoms, making it a popular choice. However, magnesium threonate may offer extra cognitive benefits but at a higher cost and potential side effects. Determining a personal dose that balances benefits with tolerance is important.
What to enjoy or watch next
If you are curious about trying magnesium for better sleep, start with a lower dose to assess your body's reaction and look for trusted brands certified by third parties like USP or NSF that clearly list elemental magnesium content. Be mindful of possible digestive side effects such as diarrhea, especially when beginning supplementation.
Remember that magnesium isn’t a universal remedy and should be avoided or used cautiously by individuals with kidney disease or those on certain medications like diuretics and proton pump inhibitors. Consulting a healthcare professional before adding magnesium supplements can help ensure safety and tailor the approach to your needs.
