Can magnesium help promote brain injury recovery?

Magnesium is one of the most abundant minerals in the body and is involved in more than 300 bodily reactions. Additionally, it’s suggested that magnesium may hold some neuroprotective benefits that can help promote recovery after TBI.

This article will discuss what evidence regarding the role of magnesium for brain injury recovery shows and share some ways to naturally increase your magnesium intake.

Magnesium for Brain Injury Recovery

A rapid decline in magnesium levels has been observed in the bloodstream after brain injury. When the body lacks magnesium, it may not function optimally.

Magnesium contributes to the regulation of many major bodily functions, including:

• Muscle contraction
• Blood pressure
• Insulin metabolism
• DNA, RNA, and protein synthesis
• Nerve transmission
• Neuromuscular coordination
• Protecting against excitotoxicity
• Cellular energy metabolism

It’s also suggested that magnesium has multiple neuroprotective benefits that can reduce the progression of secondary damage following traumatic brain injury.

For example, magnesium inhibits the actions of glutamate receptors. Glutamate is a powerful neurotransmitter that excites nerve cells and helps them send signals between one another.

However, after a brain injury, the brain releases excessive amounts of glutamate. Too much glutamate in the brain can make the neurons exhaust themselves, which eventually leads to cell death. In fact, researchers believe this process is the main source of neuronal damage after a head injury.

By making sure there is enough magnesium in the body, individuals can promote glutamate regulation. Hypothetically, this should help reduce secondary damage following brain injury.

Magnesium also plays a role in relaxing the blood vessels, which leads to increased cerebral blood flow. Since brain injury reduces cerebral blood flow, taking magnesium may help counter that effect.

In the following section, we’ll discuss what clinical evidence suggests about magnesium for brain injury recovery.

Is There Evidence That Magnesium Aids in Brain Injury Recovery?

Generally, studies on the effects of magnesium for brain injury recovery show mixed results.

For instance, one study followed patients given magnesium sulfate within 12 hours after a closed head injury. In the end, the patients who received magnesium displayed less swelling and lower mortality compared to patients that did not.

On the other hand, another double-blind trial found that magnesium had no significant impact on survival or neurological recovery. This study was conducted on patients within 8 hours of injury and continued for five days.

While magnesium appears to have neuroprotective benefits that can apply to traumatic brain injury, clinical studies fail to show consistent results. Most studies do not show any significant improvement in cognitive function compared to a placebo.

However, that doesn’t mean magnesium can’t help patients with other problems. After brain injury, individuals may experience additional effects such as emotional changes and headaches.

This study found that magnesium performed just as well as some antidepressant drugs at reducing depression. Likewise, this study found that magnesium can reduce migraine frequency by about 50%.

Although more research is necessary, current evidence seems to indicate that while magnesium will not repair the brain, it may help relieve some of the more severe secondary effects of TBI.

Now that you understand how important magnesium is for optimal functioning, let’s discuss how to increase your magnesium intake.
