What is the effect of magnesium on neuronal activity in humans?

This article will explore the worlds of nutrition and neurology, focusing specifically on how minerals like magnesium can influence brain activity. In my role as a nutritionist and dietician, I will help you to understand magnesium's impact on our neurons and its potential benefits or disadvantages. Also, you can expect to find out about the sources of magnesium as well as tips for maintaining a balanced level of this mineral.

Magnesium and Neuronal Activity

Magnesium is essential for many biochemical reactions in our body. However, its importance for neuronal function is of particular note. According to research from the National Institutes of Health, magnesium acts as a natural NMDA antagonist that helps control neuronal excitability. This mineral helps to prevent overstimulation, which can lead to neuronal damage. It also promotes optimal brain health.

A sufficient intake of magnesium is linked with improved mood, cognitive function and memory. According to a recent study in the Journal of Alzheimer's Disease, magnesium deficiencies can cause neurological disorders such as depression and migraines.

Starting off: Ensure adequate magnesium intake

Magnesium is essential for optimal neuronal function. RDA for magnesium is between 310 and 420mg per day for adults, depending on their age and gender. Studies show, however, that most people do not meet their magnesium requirements through diet alone. Supplementation is therefore a necessity.

Important to know that too much magnesium in supplements can lead to side effects such as nausea, diarrhea and abdominal cramps. It's important to speak with your healthcare provider prior to starting any new supplementation program.

More Tips and Suggestions

Aside from supplementation and dietary changes, lifestyle modifications can improve your body's absorption and utilization of magnesium. Exercise, such as regular exercise, can improve the uptake of magnesium in muscles. Limiting alcohol intake, which interferes with magnesium absorption may also be helpful.

Stress management can also be crucial, as chronic stress depletes magnesium in the body and negatively impacts neuronal function. Yoga, meditation and deep breathing techniques can be used to manage stress.


Magnesium plays a vital role in the neuronal function and affects mood, memory, cognitive functions, etc. It is important to ensure that you are getting enough magnesium, both through your diet and possibly through supplements, in order to maintain optimal brain health. Consult your healthcare provider prior to starting any new diet or supplementation plan.
