Is Your Brain Wired and Tired? Magnesium May Be the Missing Link

By Dr. Greg Fors
Have you ever crawled into bed completely exhausted, only to discover your brain apparently didn’t get the memo?
Your body is tired.
Your eyes are tired.
Your spouse is asleep.
Even the dog is asleep.
But your brain? It has suddenly decided that 11:00 p.m. is the perfect time to review every mistake you’ve made since third grade, plan next year’s vacation, solve world hunger, and wonder why the neighbor’s garage light is still on.
Welcome to what I call the “wired and tired” brain.
I see it every week in my clinic. Patients tell me:
“Dr. Fors, I’m exhausted all day long, but the minute my head hits the pillow, my brain turns on.”
Sound familiar?
If so, one of the most overlooked factors may be a simple mineral deficiency: magnesium.
The Mineral Most People Are Missing
Magnesium is involved in more than 300 biochemical reactions throughout the body. It helps regulate blood sugar, blood pressure, muscle function, energy production, nerve transmission, and perhaps most importantly for many people : sleep.

Yet research suggests that nearly 80% of American adults fail to meet optimal magnesium intake requirements. [1]
That’s a problem.
Because magnesium acts like one of the body’s natural brakes.
Without enough magnesium, the nervous system becomes overstimulated. The brain stays alert when it should be relaxing. Muscles remain tense when they should be releasing. Thoughts continue racing when they should be slowing down.
The result? A brain that feels like it drank three cups of coffee right before bedtime.
Your Brain Has Both an Accelerator and a Brake
Think of your nervous system like a car. You have an accelerator pedal that keeps you alert, focused, and ready for action. You also have a brake pedal that helps you slow down, relax, and eventually sleep.

One of magnesium’s most important jobs is helping activate the braking system. It supports GABA (gamma-aminobutyric acid), one of the brain’s primary calming neurotransmitters. [2]
GABA helps quiet excessive brain activity, reduce nervous system stimulation, and prepare the body for sleep. When magnesium levels are low, that calming signal weakens. The accelerator remains stuck down while the brakes barely work. That’s when people describe feeling anxious, restless, overstimulated, and unable to “turn their brain off.”
Why You Wake Up at 3 A.M.
One of the most common complaints I hear at the Pain and Brain Healing Center is:
“I fall asleep okay, but then I wake up at 2 or 3 in the morning and my brain is suddenly wide awake.”
Magnesium deficiency may contribute to this pattern. Magnesium helps support healthy melatonin production, the hormone responsible for maintaining your circadian rhythm and signaling that it’s time to sleep. [3]
When magnesium levels are inadequate, melatonin production may become less efficient, leading to fragmented sleep and early-morning awakenings. The result is often that frustrating experience of staring at the ceiling while your brain decides it’s time for a committee meeting.
Unfortunately, you’re the only committee member present.
Why Magnesium Deficiency Is So Common
Many people assume they get enough magnesium because they eat reasonably well. Unfortunately, that isn’t always true. Modern agriculture has depleted many soils of minerals compared to decades ago.
On top of that, magnesium is rapidly depleted by:
- Chronic stress
- High sugar intake
- Alcohol
- Processed foods
- Certain medications
- Insulin resistance
- Excessive sweating
- Poor digestive absorption
In other words, the exact same people most likely to need magnesium are often the people losing it the fastest.
Timing Matters More Than Most People Realize
Many people take magnesium randomly. Some take it in the morning. Others remember whenever they happen to see the bottle.
But magnesium works best when used intentionally. I generally recommend taking magnesium approximately 30 to 60 minutes before bedtime.
Why? Because magnesium doesn’t simply provide a nutrient. It provides a signal.

When taken consistently at the same time each evening, it becomes part of your brain’s nightly shutdown routine. Think of it like a sleep trigger. Over time, your nervous system begins recognizing:
“The magnesium is here. The lights are dim. The book is open. Sleep must be coming soon.”
Your brain loves predictable patterns. The more consistent the routine, the stronger the sleep signal becomes.
My Preferred Form: Magnesium Glycinate
Not all magnesium supplements are created equal. Many inexpensive forms are poorly absorbed and simply end up in the toilet.
One of my favorite forms is magnesium glycinate. Why? Because it provides two calming compounds:
- Magnesium: Supports relaxation, GABA activity, muscle relaxation, and healthy sleep regulation.
- Glycine: An amino acid that acts as a calming neurotransmitter and supports healthy sleep architecture.
Together they make an excellent combination for many people struggling with a wired and tired brain. At Biospec Nutritionals, we utilize a highly absorbable magnesium glycinate formula for this reason.
How Much Magnesium Should You Take?
The honest answer is: it varies. Every person absorbs and utilizes magnesium differently.
One of the easiest ways to know you’re approaching your optimal dose is that:
- You sleep better
- You feel calmer
- Muscle tension decreases
- Bowel regularity improves
In fact, one of the most reliable signs that you’ve exceeded your ideal dose is loose stools. When that happens, your body is essentially telling you: “Thank you very much, but I can’t absorb all of this.”
Excess magnesium remains in the bowel, pulls water into the colon, and produces softer stools. That’s your cue to slightly reduce the dosage.
What About Liposomal Magnesium?
Some individuals have significant digestive issues or absorption challenges. In those cases, liposomal magnesium may offer advantages. Liposomal delivery wraps magnesium inside microscopic fat-based spheres called liposomes. These tiny carriers help protect magnesium during digestion and improve cellular delivery. For some individuals, this can result in improved absorption and better clinical outcomes.

Don’t Forget the Other Half of the Equation
Magnesium helps. But magnesium isn’t magic. If you’re drinking caffeine all afternoon, staring at bright screens until midnight, and watching breaking news while scrolling social media in bed, magnesium can only do so much.
Your brain still needs healthy sleep signals. I encourage patients to:
- Get morning sunlight exposure
- Exercise regularly
- Maintain a consistent bedtime
- Reduce evening screen exposure
- Keep the bedroom cool and dark
- Avoid large meals close to bedtime
When these habits are combined with proper magnesium supplementation, the results are often remarkable.
Take Control of Your Sleep
Sleep isn’t a luxury. It’s one of the most powerful healing tools your body possesses. When sleep suffers, inflammation rises. Blood sugar worsens. Memory declines. Stress hormones increase. Recovery slows. And life simply becomes harder.
If you’ve been living with a wired and tired brain, don’t assume it’s just aging. Often it’s your body asking for the nutrients and habits it needs to properly shut down. Sometimes the difference between lying awake for hours and sleeping peacefully starts with something as simple as magnesium.
And that’s a pretty good trade.
