Is magnesium good for your memory?

Do you experience frequent forgetfulness or mental fatigue? Magnesium, often associated with relaxation, also plays a leading role in your brain health .

This mineral actively participates in the protection of your nerve cells and supports memory and concentration.

The role of magnesium in your brain health

For your nervous system to be both calm and efficient, it needs magnesium. This mineral helps perform more than 300 tasks in the body , especially those that support your brain.

When there isn't enough of it, your brain's messaging system slows down and your nerve cells quickly become exhausted. Think of it as the great stabilizer that helps your brain work smoothly, without overheating.

How does magnesium affect brain function?

Magnesium has multiple effects on the brain. On the one hand, it stabilizes the membranes of neurons, protecting them from overstimulation that could damage them.

On the other hand, it is essential for communication between neurons, as it regulates the action of several neurotransmitters , the chemical messengers that transmit signals.

Finally, it participates in the production of ATP, the molecule that provides the energy needed for the functioning of all your cells, including brain cells.

The impact of magnesium on your brain's plasticity

This mineral directly influences brain plasticity , that is, your brain's ability to change, create new connections, and adapt. This ability is central to learning and memory.

By promoting healthy and responsive neural connections, magnesium supports your ability to acquire new knowledge and consolidate memories over the long term.

The benefits of magnesium on memory and concentration

A brain well-nourished with magnesium is a more efficient brain. This nutrient helps maintain good cognitive health by acting on memory, attention, and mental clarity.

Its calming effects on the nervous system also contribute to a mental environment conducive to reflection and concentration.

Improving memory and attention span

Magnesium supports memory consolidation , the process that transforms a short-term memory into a lasting one. Studies show that adequate magnesium levels are associated with better cognitive performance.

By improving communication between neurons, it facilitates the processes of recording and recalling information, resulting in better attention in everyday life.

Reducing mental fatigue for greater clarity

Mental fatigue and brain fog are often linked to stress and an overworked nervous system. Magnesium helps regulate the stress response, thus preserving your mental energy.

For students during exam periods, adults under heavy workload, or people prone to migraines , a proper intake of magnesium helps maintain a sharper mind and better concentration .

Signs of magnesium deficiency on cognitive function

Chronic stress is a major consumer of magnesium. Even a slight deficiency can quickly manifest itself through symptoms that affect your mental well-being and cognitive functions .

Less magnesium means less neuronal efficiency, which can result in a feeling of persistent mental fatigue.

Here are some common signs that may indicate a magnesium deficiency :

• Increased irritability and nervousness

• Difficulty concentrating and frequent forgetfulness

• Decreased motivation and general fatigue

• Sleep disorders that affect brain recovery

• A feeling of "mental fog"

Which sources of magnesium should you choose for your brain?

To benefit from the effects of magnesium on your memory, it is advisable to turn to a variety of food sources and, if necessary, to quality food supplements.

The goal is to choose forms that your body can easily absorb and use, especially at the level of the nervous system.

Foods rich in magnesium to maintain memory

A balanced diet is the first step to maintaining good magnesium levels. Regularly include foods like almonds , cashews , and pumpkin seeds.

Dark chocolate (over 70% cocoa), bananas , avocados and leafy green vegetables like spinach are also excellent sources.

Also consider legumes (lentils, chickpeas) and certain mineral waters naturally rich in magnesium.

Forms of supplements with high bioavailability

If supplementation is being considered, not all forms of magnesium are created equal.

For targeted action on the brain, it is recommended to favour those which are well absorbed by the body and which pass the blood-brain barrier , this filter which protects the brain.

Combining it with vitamin B6 is often suggested because it improves the absorption and use of magnesium by cells.

Form of magnesium	Bioavailability	Main action on the brain
Magnesium bisglycinate	Very high	Soothing and relaxing action on the nervous system, ideal for stress and sleep.
Magnesium citrate	High	Supports energy production (ATP) and helps fight mental fatigue.
Magnesium malate	High	It also participates in the energy cycle, which is useful in cases of physical and mental fatigue.

Protecting your neurons against oxidative stress

The brain is a major consumer of oxygen, making it particularly vulnerable to oxidative stress , a process linked to cellular aging. Magnesium plays a neuroprotective role by acting as an indirect antioxidant.

It helps protect nerve cells from damage caused by free radicals, thus helping to preserve their integrity and function in the long term.

Regulating cortisol to preserve long-term memory

Cortisol , known as the stress hormone, can negatively affect memory when produced in excess and chronically. Magnesium helps regulate cortisol production, thus limiting its negative impact on the hippocampus, a brain region crucial for memory.

A good magnesium balance therefore contributes to a hormonal environment more favorable to cognitive health .

Magnesium support in the face of cognitive aging

As we age, maintaining optimal cognitive function becomes a priority. While no single nutrient can stop time, adequate magnesium intake supports brain health throughout life.

By participating in neuroprotection, stress management and synaptic plasticity, this mineral helps maintain the vitality of your brain and support your memory .

When is magnesium supplementation justified?

Supplementation may be relevant in certain specific situations where needs are increased or intake is insufficient. This is particularly the case during periods of intense intellectual work , persistent nervous fatigue, or to support memory problems that can appear with age.

However, it is always recommended to consult a healthcare professional before starting a course of magnesium supplements. This precaution is especially important if you are taking medication or suffer from kidney failure, as there are contraindications.

At SuperNutrition, we recommend magnesium combined with Omega 3 for optimal cognitive comfort.

FAQ: Practical questions about magnesium and memory

Is there a specific form of magnesium for the brain?

Yes, magnesium L-threonate is a form specifically studied for its cognitive benefits. Research suggests it has a superior ability to cross the blood-brain barrier, making it particularly interesting for supporting memory and brain plasticity.

For memory, is it better to take magnesium in the morning or in the evening?

For overall benefit, the evening is often ideal. Deep sleep is essential for memory consolidation. Magnesium promotes relaxation and restorative sleep, so taking it in the evening indirectly supports this nighttime brain process.

Is it safe to take a magnesium supplement with coffee or tea?

It's best to avoid it. The caffeine and tannins in tea can decrease magnesium absorption and increase its elimination through urine. For optimal effect, it's recommended to leave at least two hours between taking your coffee/tea and your supplement.

Is magnesium recommended for students' concentration?

Yes, it can be a valuable ally during exam periods as it helps manage stress and mental fatigue. However, consulting a healthcare professional is recommended to confirm the need and ensure that the intake remains within the recommended nutritional limits for their age.
