Did you know that nearly half of U.S. adults and kids aren’t getting enough magnesium in their diet? Since magnesium plays a role in sleep, not getting enough of it might be why you're having trouble sleeping. But don’t worry—magnesium supplements could help! Let’s dive into what magnesium is, how it can improve your sleep, and what you should look for when choosing a supplement.
What Is Magnesium?
Magnesium is an essential mineral that your body needs to stay healthy. It’s involved in a lot of important stuff like muscle function, nerve health, bone development, blood sugar control, and even heart rhythm. Plus, it helps keep your sleep on track. If your magnesium levels are low, you might find it harder to fall asleep or stay asleep.
To keep your magnesium levels where they should be, you can eat magnesium-rich foods daily, or if you’re not getting enough through food, supplements can help. The general recommendation for adults is between 310 and 420 milligrams of magnesium per day, depending on your age, gender, and whether you're pregnant.
How Magnesium Can Help You Sleep Better
Magnesium has been shown to improve sleep in several ways. People who have higher magnesium levels tend to sleep better and feel more rested during the day. Studies have even found that magnesium helps older adults fall asleep faster and prevents waking up too early.
But how does magnesium work its magic? While experts are still figuring out exactly how it helps with sleep, we know it affects certain brain chemicals like GABA and melatonin, which play big roles in how relaxed and sleepy you feel.
Magnesium and Insomnia
If you struggle with insomnia—whether that’s trouble falling asleep or staying asleep—magnesium might help. One study showed that adults in their 60s slept longer and woke up less often when they took magnesium supplements. Of course, more research is needed, but many people have found magnesium helpful for insomnia.
Dr. Abhinav Singh, a sleep expert, says, “Magnesium may help with sleep problems, especially if they’re related to a magnesium deficiency, like leg cramps.”
Magnesium and Restless Legs Syndrome (RLS)
A lot of people take magnesium to help with leg cramps and restless legs syndrome (RLS), which is when you feel uncomfortable sensations in your legs that make it hard to sleep. Some research shows magnesium might help with leg cramps, especially during pregnancy, and could be linked to fewer RLS symptoms.
However, we need more studies to know for sure if magnesium is a solid treatment for RLS. Right now, it seems like magnesium supplementation at recommended doses is safe and may help, but it’s not a guaranteed fix for everyone.
Magnesium vs. Melatonin: What’s the Difference?
You’ve probably heard of melatonin, another popular supplement people use for sleep. While magnesium is a mineral, melatonin is a hormone produced by your brain when it gets dark. Both magnesium and melatonin can help regulate sleep, but in different ways.
Melatonin helps you feel sleepy by signaling to your brain that it’s time for bed. It’s often used to reset your sleep schedule or to help with jet lag. Magnesium, on the other hand, impacts brain chemicals that help you relax and fall asleep. It’s not a “sleep hormone” like melatonin, but it plays an important role in helping your body settle down for the night.
How to Choose Magnesium Supplements for Sleep
If you want to try magnesium supplements for better sleep, there are a few things to keep in mind. Since supplements aren’t regulated by the FDA in the same way as prescription medications, you need to be careful about which one you choose.
Here’s what to look for:
-
Formulation: Magnesium comes in different forms, and some are easier for your body to absorb. Magnesium glycinate is a good option for sleep, as it's more easily absorbed and less likely to cause side effects.
-
Dose: Experts suggest taking no more than 350 milligrams of magnesium per day to avoid side effects. Some supplements offer higher doses, but it’s best to stay within the recommended limit.
-
Brand: Always choose reputable brands that have their supplements tested by a third party. This ensures that what’s on the label is actually in the bottle and that the product is free from harmful substances like mold or heavy metals.
Magnesium glycinate is often recommended by sleep experts because it’s well-absorbed and can help promote calmness and better sleep.
Frequently Asked Questions About Magnesium
How Much Magnesium Should I Take?
The right amount of magnesium depends on your age and health needs, but it’s generally safe to take up to 350 milligrams per day. Taking more than that can lead to side effects, like diarrhea.
What Foods Are High in Magnesium?
Magnesium is found in a variety of foods, including seeds (especially pumpkin and chia), leafy greens, nuts (like almonds and cashews), beans, and fish such as salmon and halibut. Eating these foods can help you get enough magnesium.
Does Magnesium Have Any Side Effects?
Taking too much magnesium (more than 350 milligrams a day) can cause issues like diarrhea, nausea, or stomach cramps. Some forms of magnesium, like magnesium oxide, are more likely to cause side effects, so it’s good to go with forms like magnesium glycinate.
Is It Safe to Take Magnesium Every Day?
For most people, it’s safe to take magnesium daily, as long as you stick to the recommended dose of 350 milligrams. If you're on medication or have a health condition, it's a good idea to talk to your doctor before starting a magnesium supplement.
Final Thoughts
Magnesium can be a great addition to your routine if you're struggling with sleep issues. It might help you fall asleep faster, stay asleep longer, and feel more rested when you wake up.
