What is the best magnesium supplement for sleep?

Best Overall: Magnesium Glycinate by Double Wood Supplements

Double Wood’s Magnesium Glycinate supplement is our top choice for several reasons. First, it provides 400mg of magnesium from a highly-absorbable source: magnesium glycinate. This form of magnesium is also used in several research studies on magnesium and sleep, stress, and relaxation.  Additionally, this supplement is third-party tested to ensure quality, potency and purity.

Best Glyphosate Residue Free Magnesium for Sleep: Essential Magnesium by Organifi

Glyphosate is a pesticide that’s sprayed on conventionally grown crops, and some research suggests that these pesticides can bind with minerals in plant-based sources — which limits our ability to absorb them. Fortunately, Organifi’s entire product line-up is organic and/or certified to be free of glyphosate residues. This magnesium supplement is also made with easy-to-absorb magnesium glycinate, making it an excellent choice for people trying to improve their magnesium status to support healthy sleep.

Best Budget Magnesium for Sleep: Magnesium Caps by Life Extension

If you’re on a limited budget, this magnesium supplement from Life Extension is a great choice — working out to under $3 per month. It contains three different types of magnesium to help boost absorption. However, the magnesium oxide and magnesium citrate it contains — though inexpensive — are more poorly absorbed than other types.

Best Magnesium Powder for Sleep: Magnesi-Om by Moon Juice

If you want to build a calming ritual around your nighttime magnesium, then a tasty magnesium-rich drink is the perfect choice. With added L-theanine, this supplement — available in Berry, Blue Lemon, or Naked (unflavored) — makes an ideal nightcap to help you relax and unwind before bed. It’s also third-party tested and made with three forms of magnesium for optimal absorption. 

Best Magnesium Gummy for Sleep: Magnesium Gummies by Nordic Naturals

Although gummies generally aren’t the best way to get adequate doses of certain nutrients, they’re a good option for people who dislike or have trouble swallowing pills. These gummies from Nordic Naturals are made with natural flavors and colors, so you can look forward to taking them. It’s important to note that they do contain some added sugar for sweetness, though.

Best Magnesium Complex for Sleep: Magnesium Complex by Just Ingredients

Magnesium complexes are supplements that contain multiple forms of magnesium in a single dose. This is thought to help boost overall magnesium absorption and increase the benefits of supplementation. The Just Ingredients formula contains highly bioavailable magnesium carbonate, magnesium malate, magnesium orotate, magnesium taurinate, and magnesium bisglycinate. It’s also free of fillers and artificial ingredients.

Best Magnesium on Amazon for Sleep: Magnesium Glycinate by Pure Encapsulations

If you’re a Prime member, you may be wondering which magnesium supplement on Amazon is the best. While several of the options we mentioned above are also available on Amazon, we also like the magnesium glycinate from Pure Encapsulations. In addition to being third-party tested, this supplement is hypoallergenic and non-GMO. It’s also highly rated on Amazon with over 30,000 reviews averaging 4.7 out of 5 stars.

Best Magnesium Supplements for Sleep FAQs

What type of magnesium supplement works best for sleep? 

Magnesium glycinate is one of the best forms of magnesium to help promote better sleep. This magnesium is highly bioavailable, meaning it’s easy for the body to absorb and use. However, the relationship between magnesium and sleep isn’t entirely clear. Some research suggests that magnesium supplementation can improve sleep in people with poor magnesium status, but more research is needed.

Is it OK to take magnesium every night for sleep?

It is OK to take magnesium supplements nightly as long as you follow the recommended dosage and do not take more than one serving daily. If you are concerned about overdoing it, you can ask your healthcare provider to check your magnesium status and offer individualized advice about supplementation.

When is the best time to take magnesium supplements for sleep?

According to several research studies, the timing of your magnesium dosage is not a major factor. You can take magnesium at any time of day, or split your dosage and take it multiple times per day, to reap the benefits. However, forming rituals or habits around bedtime can also help support rest and encourage sleep — so taking magnesium as part of your nightly pre-bed routine can also be advantageous.

Are there any side effects of taking magnesium supplements for sleep?

In correct doses, magnesium is unlikely to cause any significant side effects. However, high-dose magnesium is often used as a laxative. If you take high doses of magnesium, you may experience nausea, diarrhea, gas, or other gastrointestinal symptoms. 

What foods are high in magnesium that can also aid sleep?

Some of the most magnesium-rich foods to include in your diet are pumpkin seeds, chia seeds, almonds, spinach, and cashews. Generally, nuts, seeds, beans, and other plant foods are good sources of magnesium. Nuts and seeds are also rich in protein and healthy fats, so they make an ideal bedtime snack.
