Does magnesium help you sleep? In short, yes. Using magnesium for sleep is a great, natural way to get some rest at night. While this mineral is incredibly important to your body overall, it’s not one that your body actually produces, so you have to find it in food and supplements. Here, we’ll discuss all things magnesium and sleep, including the best time to take magnesium, the relationship between magnesium glycinate and sleep, the side effects of too much magnesium and more.
What is Magnesium?
Magnesium is a mineral. Though it’s essential in helping your body function, it’s not a substance that your body produces. We get this mineral from supplements and our diets, and it contributes to keeping muscles healthy, keeping bones strong, regulating blood pressure, and, of course, helping us sleep. About half the magnesium in your body can be found in your bones, and the rest is distributed around, mainly in your soft tissue.
According to the National Institutes of Health, women need about 310-320 mg of magnesium in a day, and men need about 400-420 mg of magnesium a day.
How Does Magnesium Improve Sleep?
There are a few different ways that magnesium can affect your sleep. Because this mineral is so crucial in helping your body with a variety of things, that means there are myriad ways that can, in turn, help you sleep better.
Of course, the primary way magnesium improves sleep is by getting right to the core of insomnia. Proper levels of magnesium can regulate the amino acid GABA, according to studies, which helps your brain shut off and welcome sleep.
Magnesium helps you manage stress and anxiety. It works by regulating the sympathetic and parasympathetic nervous systems, finding a balance and helping your body deal with stress. With magnesium’s assistance, your systems can remain even-keeled, and with less stress, you’re bound to sleep better.
Magnesium, similarly to potassium, can help stop your muscles from cramping. This can help in a couple of ways. Some studies have shown that some magnesium combos have decreased nighttime muscle cramps, making it more comfortable to sleep. It’s also thought that magnesium can help prevent restless leg syndrome because it keeps your legs from locking up. Magnesium can also be beneficial for pregnant women who experience any muscle spasms during the night.
Magnesium can help with emotions as well. It’s been shown to help with depression, though there hasn’t been much research done on this yet. There has been a correlation, though, between magnesium supplements and reduced depression symptoms, which, in turn, has led to improved sleep.
Sources Of Magnesium
You can, of course, get magnesium from foods, but there are other places to reap the benefits of this mineral. Because it’s not naturally produced by the body, it’s important to take magnesium every day. Your body needs a few hundred milligrams of it every day to help regulate everything, so here’s where you can find magnesium.
It’s pretty easy to get your daily recommended amount of magnesium from your diet alone, as long as you’re a pretty healthy eater. Magnesium is found in a lot of foods, including:
- Dairy milk
- Soy milk
- Fish like halibut and salmon
- Vegetables like leafy greens, squash, broccoli, and avocados
- Seeds and nuts like cashews, almonds, sunflower seeds, and sesame seeds
- Peanut butter
- Beef and chicken
There are a few ways to take in a magnesium supplement. Some of them will be pure magnesium, but some are a combination. Magnesium citrate, for example, is a mixture of the two that not only helps you sleep but can also calm you down. Citrate is known for its calming properties, making this a really good option if you’re looking for sleep benefits.
Magnesium glycinate is another supplement that’s great for sleep because glycine is also an amino acid that promotes sleep. These two together have been proven to improve sleep.
What Happens When You Don’t Have Enough Magnesium?
Not having enough magnesium in your body will do more than affect your sleep. As we said, it’s one of those minerals that does a lot of things for you, so not having enough in your body can lead to larger issues.
- Osteoporosis: Because magnesium is so essential to bone health, without enough of it, your bones may not be as strong, leading to osteoporosis.
- Stroke: There’s been some research done that shows an increased intake of magnesium lowered the risk of stroke; thus, a magnesium deficiency can increase the risk of stroke.
- Cardiovascular disease: Heart problems are already so prevalent, and studies have proven that having enough magnesium in your body can lower your risk.
- High blood pressure: Supplemental magnesium can also manage blood pressure, which means a deficiency in this mineral puts you at risk for high blood pressure.
Additional Health Benefits
Have we mentioned that magnesium goes a long way in helping your body? Because it does. Yes, it can help you sleep better at night, but it can also help with all of these things too:
- Improved mood
- Less stress
- Pain relief
- Bone health
- Metabolic health
Potential Side Effects of Magnesium
It’s important not to consume too much magnesium. Most likely, you won’t do this with your diet, but taking too many magnesium supplements could cause side effects like diarrhea, nausea, and cramping, and extreme overdoses of magnesium can lead to heart problems, coma, and even death. However, you’d have to consume a very large amount of magnesium to reach these levels.
