Magnesium threonate is a form of the essential mineral magnesium. The body requires magnesium for various functions, including protein synthesis, glucose control, and nerve function.
Magnesium is essential for many of the body’s processes. According to a
Magnesium threonate, or
This article looks at magnesium threonate, its benefits, and possible side effects. It also explores the importance of magnesium in the body and the symptoms an individual may experience with magnesium deficiency.
Some animal studies have found that magnesium threonate can increase magnesium ions in the brain and improve cognitive function.
For example, a
In light of these findings, people may take magnesium L-threonate for its potential cognitive benefits and to normalize their magnesium levels. However, there is a lack of research to support these effects in humans.
Magnesium threonate could have

If an individual ingests
Ingesting more than 5,000 milligrams (mg) of magnesium per day, usually from magnesium-containing laxatives and antacids, can cause magnesium toxicity, leading to symptoms such as:
- low blood pressure
- urine retention
- muscle weakness
- nausea and vomiting
- difficulty breathing
- irregular heartbeat
- cardiac arrest
Some medications can affect magnesium levels or interact with magnesium supplements. People taking the following medications should discuss their magnesium intake with a healthcare professional:
Recommended dietary allowances (RDAs) are the intake levels of essential nutrients that meet the nutrient needs of most people.
Currently, no recommended daily allowance exists for magnesium L-threonate.
Magnesium intake recommendations vary. The RDAs for males and females over 31 years are
These values change for females during pregnancy and lactation as follows:
|Magnesium RDA during pregnancy
|Magnesium RDA during lactation
|Females aged 19–30 years
|Females aged 31–50 years
The Office of Dietary Supplements states the upper limits for magnesium supplements and medications. The upper limits are lower than RDAs because RDAs include magnesium from all sources, including diet and supplements.
The upper limit for supplemental magnesium for males and females aged 19 years and over, including pregnant and lactating females, is 350 mg. People taking magnesium supplements and medications containing magnesium should ensure they do not exceed this dose. If in doubt, discuss magnesium intake with a healthcare professional.

However, people may develop a magnesium deficiency if they eat a diet low in magnesium, have an alcohol use disorder, take certain medications, or have certain other health conditions.
Early symptoms of magnesium deficiency include:
- loss of appetite
If the deficiency continues, a person may develop:
In severe cases, the individual may also develop low serum calcium or potassium levels because of the disruption to how their body manages mineral homeostasis or balance.

Magnesium threonate is one of the various forms of magnesium. Magnesium is an important mineral in the body.
Magnesium is essential for over 300 enzyme reactions and plays a role in DNA synthesis, muscle and nerve function, mental abilities, and more.
If an individual has a magnesium deficiency, they can experience symptoms ranging from nausea and vomiting to severe heart problems.
Animal studies suggest that magnesium threonate may have benefits for cognitive function but there is no evidence of this effect in humans.
