What Is the Best Magnesium to Take for Insomnia?

Here are the best kinds of magnesium for sleep, along with their unique properties and strengths.

1. Magnesium Glycinate: The Calming Champion

Many medical professionals recommend magnesium glycinate for sleep optimization. This is because glycine acts as a calming neurotransmitter, enhancing magnesium’s own calming effects. This makes it highly effective for lowering anxiety and calming the mind before sleep. It also supports muscle functioning.

However, it’s important to consult medical professionals before adding a new supplement to your diet, especially for people with kidney diseases.

2. Magnesium Citrate: The Gentle Relaxer

Magnesium citrate is known for its good bioavailability. It has an osmotic effect, drawing water into your bowels and promoting gastrointestinal health. Magnesium citrate also offers relaxation effects. However, it should be managed thoughtfully as it can cause digestive issues when used incorrectly.

3. Magnesium L-Threonate: The Brain Booster

Magnesium L-threonate is widely regarded for its ability to cross the blood-brain barrier, which is typically highly impermeable. It is a newer and patented form of magnesium.

It can increase magnesium levels in your brain, which greatly improves cognitive health, memory and neuroplasticity. It is also able to calm the brain, especially for those with racing thoughts and anxiety.

4. Other Forms of Magnesium

There are other forms of magnesium that are less well known than the previous three. Magnesium oxide has poor bioavailability, even though it is high in elemental magnesium. As such, it doesn’t help much with sleep support or with alleviating magnesium deficiency. Instead, it is used as a laxative.

Another one is magnesium malate. This type of magnesium is bound to malic acid. It can be energizing for some, which is why many people take it in the morning rather than before sleep.

Frequently Asked Questions (FAQs)

Here are the most frequently asked questions about using magnesium to optimize sleep.

Can I take magnesium with MTHFR?

Yes. Magnesium is recommended for people with the MTHFR gene mutation. It is included in the treatment list for methylation issues along with other nutrients such as calcium, vitamin B6, vitamin C, zinc and methionine. However, it’s best to consult your doctor for more personalized medical advice.

Can I take magnesium glycinate while on GLP-1?

GLP-1 agonists may cause digestive side effects. Currently, there are no major known contraindications, but it is still critical to consult your prescribing doctor before adding any new supplements to avoid potential negative interactions. You can include whole, complex carbohydrates such as pasta and rice to improve your magnesium levels and keep you asleep.

What is the strongest or best magnesium for sleep?

Strength can be measured through a medicine’s bioavailability and targeted effect. Both magnesium glycinate and magnesium L-threonate are strong in these areas. Glycinate is especially effective for calming the nervous system, while L-threonate is highly effective in crossing the blood-brain barrier.

Pair taking supplements with good sleep hygiene. For example, setting your room temperature between 60° and 67°F can help you fall asleep more easily.

Is magnesium citrate or glycinate better for insomnia?

Magnesium glycinate is objectively better for helping treat insomnia, as it calms the nervous system. However, taking too high a dose at night can cause digestive discomfort.

Your Journey to Better Sleep Starts Tonight

Achieving restorative sleep is crucial for your overall health. Magnesium is a safe and powerful mineral that addresses typical barriers to rest, like anxiety and an overactive mind.
