The surprising link between magnesium and your memory
As we age, we may notice that our memory might not function the way it used to. Suddenly names, words and even past events are not as easy to recall as before. When thinking of ways to boost our memory, we often look to brain-training games, better sleep, or even drinking more water. But there may be something you haven’t considered… magnesium.
Magnesium is mostly known for its role in muscle function and bone health support but is now gaining attention for something a little more unexpected: its ability to support brain health and memory.
Why do our brains need magnesium? Selvan Naicker, Brand Manager for CrampEase® explains that our brains need magnesium to function properly, and it is crucial for synaptic plasticity to occur (our brain’s ability to create and strengthen connections between neurons). This is key to learning and memory.
The correlation between magnesium and memory function
“Magnesium also helps regulate NMDA receptors, which play an important role in nerve signal transmission, and when these receptors are balanced, your brain can better form new memories and recall old ones,” he continues.
The correlation between magnesium and memory function can be seen in various studies. A large population-based study found that older adults with higher magnesium intake performed better on cognitive tests. The effect was strongest in women and those with good vitamin D levels. Meanwhile, the Women’s Health Initiative Memory Study followed women over 20 years and found that magnesium intake was linked to a lower risk of developing mild cognitive impairment and dementia.

Ready to increase your magnesium?
Ready to increase your magnesium? This is not a difficult change in lifestyle and can be done in your own home. Many everyday foods are packed with magnesium:
- Leafy greens like spinach and kale
- Nuts and seeds, especially almonds and pumpkin seeds
- Whole grains like brown rice and oats
- Legumes such as black beans and lentils
- Dark chocolate (yes, really!)
Another option is to add a magnesium supplement to your daily routine. CrampEase® capsules include not only magnesium but sodium, calcium and potassium, which may work together indirectly to help your cognitive function:
- Calcium is essential for nerve signal transmission helping neurons work properly.
- Sodium and potassium are electrolytes that are important for nerve impulse transmission and hydration affecting mental alertness and energy.
Magnesium might not be the first mineral you think of when it comes to memory and mental sharpness, but this powerhouse mineral is proving it’s more than just an option for your muscles. A varied diet is effective when it comes to achieving good nutrition, health, body composition as well as physical and mental well-being.
So, whether you’re a student, a busy parent, or just looking to stay sharp as you age, adding a little magnesium to your life could be a smart move for your mind.
