Magnesium is essential for supporting nerve and muscle function, producing stomach acid, and strengthening energy production. Chronically low magnesium levels can put you at risk of type 2 diabetes, high blood pressure, kidney disease, and even heart disease.
Ensuring you get enough magnesium each day can help prevent illness and physical weaknesses. Although you can get this essential electrolyte through food, it can be difficult to meet your daily recommended intake, which is where magnesium supplements come in.
However, these salts come in a variety of different forms, so how do you know which one is best for your needs? To help you choose, we take a close look at magnesium threonate and magnesium glycinate, comparing their uses, benefits, and side effects.

Both magnesium threonate and magnesium glycinate are used in supplements to increase magnesium levels and alleviate other problems like sleeplessness and anxiety, which can lead to burnout.
The main difference between these types of magnesium is their parent compounds. Magnesium threonate comes from threonic acid, which is a sugar. Magnesium glycinate comes from glycine, which is a non-essential amino acid.
Magnesium glycinate is better in some ways because it’s easier for the body to absorb non-essential amino acids. While some types may help with severe constipation, people with inflammatory bowel diseases like Crohn’s disease might prefer magnesium glycinate because it’s less likely to have a laxative effect than other types of magnesium.
Magnesium threonate, also known as magnesium L-threonate, is a magnesium salt metabolite of ascorbic acid (vitamin C). Vitamin C is a crucial aspect of iron absorption and is common in various fruits and vegetables.
L-threonate has 144mg of elemental magnesium per a 2,000mg dosage. Elemental magnesium refers to how much actual magnesium is within a magnesium salt.
There are numerous benefits to taking magnesium threonate supplements, including:
Using magnesium threonate supplements may also lead to certain potential side effects, such as:
Users should take magnesium threonate with meals to get the most comfortable and effective experience. Taking magnesium supplements without food can lead to diarrhea, bloating, cramps, and nausea.
The recommended magnesium threonate dosage for adult men is 400–420mg daily. Adult women require 310–320mg of magnesium a day, while pregnant women need more at roughly 350–360mg per day.
Magnesium glycinate is a compound consisting of magnesium bound to the non-essential amino acid glycine. As an amino acid, this type is absorbed more easily by the body than other forms of magnesium.
A 709mg dose of magnesium glycinate contains 100mg of elemental magnesium.
There is another type of magnesium glycinate called magnesium bisglycinate. Instead of having a single magnesium atom paired with a glycine molecule, magnesium bisglycinate sees magnesium bound with two glycine molecules.
These are some of the various benefits of taking magnesium glycinate supplements:
Magnesium glycinate carries some possible side effects, including:
Whether you’re using them in a pill or powder form, it’s recommended to take magnesium glycinate supplements with food to stimulate digestion and improve absorption.
Consuming the supplements on an empty stomach can also cause digestive upset, which can lead to stomach cramps, nausea, vomiting, excess gas, and bloating.
An appropriate magnesium glycinate dosage for adult men is 40–420mg per day. Women need less magnesium, 310–320mg daily. However, pregnant women need more magnesium, ideally 350–360mg each day.
Generally, magnesium is used to improve sleep because it stimulates gamma-aminobutyric acid (GABA), which slows certain brain functions and makes it easier to fall asleep. It also lowers your internal body temperature, making it easier to stay asleep comfortably.
Here are the main pros of magnesium glycinate for sleep:
By contrast, these are the primary benefits of using magnesium threonate for sleep:
Although both types of magnesium provide benefits for a good night’s sleep, we recommend magnesium glycinate. This is best for promoting restful sleep because it is an amino acid that is easier for the body to absorb.
In general, magnesium is an effective anxiety treatment as it affects the hypothalamus, a part of the brain that regulates glands that control the body’s stress response. However, although magnesium threonate and magnesium glycinate are both effective anxiety treatments, they do have some differences.
Here are some strengths for magnesium glycinate when it comes to relieving anxiety:
However, these are reasons for using magnesium threonate for anxiety:
Overall, magnesium threonate is more effective in relieving anxiety because, as previously mentioned, it has a higher bioavailability. This makes it easier for the body to absorb this type of magnesium.
Magnesium glycinate and magnesium L-threonate are different types of magnesium. They have different properties and effects on magnesium deficiencies. For example, magnesium glycinate has more elemental magnesium and smoother magnesium absorption. L-threonate, however, crosses the blood-brain barrier and has a more significant impact on memory and cognitive processes.
You can take magnesium glycinate and magnesium L-threonate together if you do so in the right dosages. For instance, adults between the ages of 19 and 51 need 310–420mg per day, depending on their specific age and gender.
Magnesium threonate helps with sleep by permeating the blood-brain barrier and getting magnesium to the brain cells effectively. It stimulates gamma-aminobutyric acid (GABA) and lowers internal body temperature. These changes make it easier to fall asleep and stay asleep, considerably improving sleep quality.
Although a large portion of people from countries with high quantities of processed foods are at risk of having magnesium deficiencies, there are several ways to address the issue.
Adult men require 400–420mg of magnesium daily, while women only require 310–320mg. Too much of this mineral can lead to abdominal pain, nausea, and diarrhea. Striking the balance is essential to avoid painful discomfort and disrupted bowel movements.
Magnesium supplements can be useful in lowering stress levels and improving your sleep, but there are other things that you can include in your daily routine to avoid burnout. For example, running each day has several benefits for both your mental and physical health.
Anyone interested in taking supplements to increase their magnesium levels should consult with a medical professional. Most of these supplements contain magnesium oxide, which is frequently used to relieve constipation.
Both magnesium glycinate and magnesium threonate are effective treatments that can lower blood pressure, improve vitamin D absorption, relieve stress, and increase sleep quality.
However, while magnesium glycinate is better for improving sleep quality and cognitive function, threonate is a more effective anxiety buster. Therefore, the type of magnesium supplement we’d recommend depends on your individual needs.
If you’re still unsure about whether you should supplement magnesium, you should speak to your doctor, who can advise you on the best course of action.
