Magnesium might promote restfulness in a couple of other ways. In response to an April 2022 examine in Sleep², the mineral prompts GABA—a neurotransmitter that calms the central nervous system. It additionally suppresses calcium ranges in muscle cells, which in flip helps muscle tissue chill out. That is why it is used to enhance each signs and sleep high quality in these with stressed legs syndrome, per a December 2022 randomized managed trial in BMC Complementary Drugs and Therapies.

“Magnesium has been proven to cut back cortisol, our stress hormone, and subsequently makes us really feel extra relaxed and prepared for sleep,” Meshulam provides. Oh, and it performs a task in melatonin manufacturing³, therefore why some sleep dietary supplements bundle magnesium and melatonin collectively.

Regardless of all these connections, Dr. Chen says the decision continues to be out on whether or not there’s night-to-night effectiveness of taking magnesium for higher sleep. “Massive-scale inhabitants research haven’t proven that magnesium actually helps individuals go to sleep a lot sooner regularly, so it’s very individualized by way of whether or not it really works,” he says.

An April 2021 paper in BMC Complementary Drugs and Therapies reported that, on common, older adults with insomnia fell asleep 17 minutes sooner when supplementing with magnesium in comparison with those that acquired placebos. But even the examine authors famous this discovering was based mostly on unclear proof, and so they labeled the affiliation between magnesium consumption and improved sleep signs “unsure.” (Womp womp.)

Which kind of magnesium is greatest for sleep?

(Actual speak: By accident taking magnesium oxide may have the reverse of your meant impact if it retains you on the bathroom all night time.)

And remember that loads of meals have this important mineral, too. Black beans, spinach, avocado, almonds, pumpkin seeds, and darkish chocolate (you are welcome) are all good sources of magnesium, per the Nationwide Institutes of Well being.

Dosage and timing of magnesium for sleep

“I like to recommend beginning at 200 milligrams of magnesium glycinate and taking it about half-hour earlier than on the brink of sleep,” Meshulam says.

Magnesium glycinate dietary supplements are typically well-tolerated and secure, but it surely’s a good suggestion to run them by your physician in case you’ve been recognized with kidney or liver illness, Dr. Chen says.

And extra magnesium isn’t all the time higher. Dr. Chen recommends capping magnesium supplementation to 400 milligrams per night time in case you’re utilizing it that will help you chill out. “An excessive amount of magnesium could cause irregular heartbeat, low blood stress, and muscle weak spot,” Meshulam says. Additionally, in case your complement offers you diarrhea, you are most likely taking an excessive amount of.

Different sleep ideas

Don’t sleep on (pun meant) a strong nighttime routine, both. Meshulam recommends easy sleep hygiene ideas like holding your bed room darkish and funky, avoiding caffeine after midday, and ending consuming not less than two to 3 hours earlier than getting in mattress. “Limiting blue mild publicity [from screens] and discovering methods to chill out, equivalent to meditating, studying, or utilizing lavender important oils, can also be useful,” Meshulam says.

Greatest magnesium dietary supplements for sleep to attempt

Earlier than attempting any new dietary supplements, it is all the time a good suggestion to run them by your healthcare supplier first. As soon as they’ve given their “okay,” attempt shopping for merchandise from respected manufacturers—as a result of nutritional vitamins and dietary supplements aren’t very intently regulated by the FDA.

“I like to recommend searching for a third-party examined complement,” Meshulam says. “This fashion you recognize you’re really getting what the model says you might be.” Search for merchandise that observe Present Good Manufacturing Practices (cGMPs) and are USP- or NSF-certified, which signifies they’ve been third-party examined. You’ll often see these distinctions on a product’s label or web site.

Two picks Meshulam loves? Thorne’s magnesium bisglycinate powder ($47 on Amazon) and Pure Encapsulations’ magnesium glycinate capsules ($26 on Amazon).

Whereas magnesium gummies are additionally a factor, you are higher off selecting an unflavored powder or capsule to keep away from pointless added sugars and meals dyes, particularly earlier than mattress. And keep in mind: Magnesium isn’t a sleeping treatment (like Ambien, for instance). It may enhance sleep onset by serving to you wind down, but it surely hasn’t been confirmed to maintain you zonked all through the night time.

“Taking magnesium earlier than mattress might assist chill out your physique and mind so you may slip off to sleep extra simply,” Dr. Chen says. “But it surely won’t have a long-lasting impact by means of the night time.”
