What I learned about Magnesium, Myelin, & Exercise

 

My short recap of Jeff Bowles's self-published book on hormones, cholesterol and much more. (p 1-90)

I'm deep in the rabbit hole of understanding why my testosterone is at 0.8 ng/dL & low cortisol. While doctors tell me I'm too young for hormones

In this book, Bowles argues with AI models (Perplexity and Grok 3) about magnesium deficiency in hormone and cholesterol production. And that's when everything clicked.

The $900 Therapy Nobody Offers in South Florida

Last year, I read an IV therapy book and became obsessed with something called phospholipid exchange therapy. It's a real thing—practiced extensively in Eastern Europe, used for mold toxicity, Lyme disease, chronic fatigue, neurotoxicity, and neurodegenerative diseases.

The therapy uses phosphatidylcholine IV infusions combined with glutathione and folinic acid to remove toxins from your cell membranes and tissues. It's brilliant. It's also expensive as hell.

I searched all of South East Florida. Nobody offered it. I found exactly one provider in Tampa charging $900 per session.

Meanwhile, every IV bar in Miami offers NAD+, glutathione, Myers cocktails, beauty drips, hangover drips—every trendy IV treatment except the one that might actually address the root problem: toxic tissues that can't absorb nutrients properly, especially

MAGNESIUM!!

The Magnesium Bomb That Explains My High Triglycerides

While Bowles argued with AI about magnesium, I learned something critical:

Magnesium is necessary for lecithin cholesterol acyltransferase (LCAT) enzyme activity.

LCAT lowers LDL cholesterol, lowers VLDL cholesterol, raises HDL cholesterol, and lowers triglycerides.

I have high triglycerides. This got my attention.

A 1984 study showed 54% reduction in LCAT activity when rats were magnesium-deficient. A 2023 PMC study confirmed: "Lecithin–cholesterol acyl transferase (LCAT), which lowers triglyceride and LDL-C levels and boosts HDL-C levels, also needs magnesium to function."

Bowles' comment in the margin: "Wow starting to look like there is a bunch of iffy science in this area of research"—meaning mainstream medicine hasn't connected these dots because there's no pharmaceutical profit in you healing yourself with a $15 mineral supplement.

The Tissue Theory That Changes Everything

Here's where my brain exploded:

Phospholipid exchange therapy removes toxins from your cell membranes and muscle tissues. Magnesium gets absorbed into your tissues, not just your blood.

If your cell membranes are loaded with environmental toxins and cellular waste—they're not functioning optimally. That includes nutrient uptake. You could have "normal" blood magnesium while your tissues are starving for it.

You're pouring magnesium into a clogged drain.

Bowles clarifies this perfectly: Magnesium deficiency happens at the tissue level, not in your blood. Blood tests lie. You can have "normal" serum magnesium and be severely deficient at the cellular level where it actually matters.

Why I Feel Like Shit After Working Out: The Biochemical Truth

Then I asked Perplexity and Grok: "Please give a detailed description at the biochemical level of how exercise depletes magnesium and also describe how severe magnesium deficiency can damage nerves."

The answer hit me like a freight train.

Exercise Destroys Your Magnesium Stores Through Multiple Pathways

1. Sweat Loss You lose 1-6mg of magnesium per liter of sweat under normal conditions. In hot environments (hello, Bikram yoga), you lose up to 15mg per liter.

I used to do Bikram yoga. 105°F heated room. 90-minute sessions. And I felt depleted afterward not energized, not zen, not refreshed. Depleted.

BOOM. I was and am magnesium deficient through sweat loss.

2. Urinary Loss Exercise increases urinary magnesium excretion. Studies show serum magnesium dropping significantly during just 90 minutes of exercise in heat—and it's not just from sweat. Your body is redistributing and losing magnesium through urine too.

3. Energy Metabolism Consumption This is the biochemical kicker: Magnesium is required for ATP production.

ATP (adenosine triphosphate) is your cellular energy currency. Every single energy-dependent process in your body requires ATP. And ATP exists as Mg-ATP complex—meaning you literally cannot produce or use energy without magnesium.

Exercise increases your energy demands. More energy = more ATP needed = more magnesium consumed.

Magnesium is also a cofactor for:

• 300+ enzymatic reactions including all of glucose metabolism
• Oxygen delivery to working muscles
• Creatine kinase activity (the enzyme that rapidly regenerates ATP during high-intensity exercise)
• Lactate clearance (magnesium lowers lactate buildup that causes fatigue)

Without adequate magnesium, your muscles can't produce energy efficiently. That's why I feel like shit after working out. My body is trying to perform while running on empty magnesium stores.

4. Redistribution from Bones and Blood During exercise, your body mobilizes magnesium from bone stores to muscle tissue to support the increased metabolic demand. After exercise, it redistributes again. This constant shuffling depletes your overall stores, especially if you're not replacing what you lost through sweat and urine.

Athletes Need 10-20% More Magnesium Than Sedentary People

Studies confirm: if you exercise regularly, your magnesium requirements are 10-20% higher than someone who sits on the couch all day.

The RDA for women is 300mg/day. If you're active, you need 330-360mg/day minimum. If you're doing hot yoga, running, intense training? You need even more.

Most people aren't getting even the baseline RDA from diet. Add exercise, and you're walking around severely depleted.

How Severe Magnesium Deficiency Damages Your Nerves

Now here's where it connects to my car accident and the nerve damage I still feel years later.

Magnesium deficiency causes axonal degeneration—actual structural damage to nerve fibers.

Magnesium keeps your arteries healthy

By preventing your blood from getting too sticky. Without enough magnesium, your arteries harden, your blood pressure rises, your heart beats irregularly, and calcium builds up where it shouldn't: in your arteries instead of your bones.

This is why low magnesium leads to both heart problems AND weak, fragile bones: the calcium goes to the wrong places.

The Biochemical Mechanisms of Nerve Damage from Magnesium Deficiency

1. Calcium Dysregulation (Excitotoxicity) Magnesium acts as a natural calcium channel blocker. When you're magnesium deficient, calcium floods into nerve cells uncontrolled. This is called excitotoxicity—excessive calcium causes neurons to fire uncontrollably, leading to oxidative stress, inflammation, and cell death.

A study in The Journal of Neurochemistry showed magnesium deficiency exacerbates calcium-mediated oxidative stress, impairing neuronal integrity and increasing susceptibility to neuropathic pain.

Translation: Burning sensations, tingling, numbness, hypersensitivity. All symptoms of nerve damage.

2. NMDA Receptor Hyperactivation Magnesium normally blocks NMDA receptors (N-methyl-D-aspartate receptors) under resting conditions. NMDA receptors are involved in pain sensitization and nerve excitability.

Without magnesium blocking these receptors, they stay open. This causes central sensitization—your nervous system becomes persistently hypersensitive to pain signals. You feel pain from stimuli that shouldn't hurt.

3. Reduced GABA (The Brain's Brake Pedal) GABA is your inhibitory neurotransmitter—it calms nerve activity. Magnesium is required for GABA release and function.

Magnesium deficiency = reduced GABA activity = increased nerve excitability. Your nerves fire too easily, too often, and you can't shut them down.

4. Impaired Myelin Formation Here's where it connects to the progesterone discovery I'll get to in a minute:

Magnesium is involved in the formation of membrane phospholipids and the myelin sheath.

Myelin is the protective coating around nerve fibers—literally a mixture of protein and phospholipid. Without adequate magnesium, your body can't form or maintain healthy myelin.

5. Oxidative Stress and Inflammation Magnesium deficiency triggers inflammatory responses that directly damage peripheral nerves. Magnesium normally neutralizes reactive oxygen species (ROS) and supports antioxidant enzymes like superoxide dismutase and glutathione peroxidase.

Without it? Oxidative stress damages your neurons, and inflammation keeps the damage going.

6. Impaired Nerve Regeneration Even if you want your nerves to heal after injury, they need magnesium to do it. Schwann cells (the cells that make myelin in the peripheral nervous system) require magnesium to proliferate, maintain the myelin sheath, and support axon growth.

Studies show low serum magnesium is independently associated with axonal degeneration—actual nerve fiber damage, not just demyelination (loss of the protective coating).

What This Means for Me

I was in a car accident years ago. I still feel nerve damage. Not one doctor mentioned magnesium for nerve repair.

They didn't mention progesterone for nerve repair either (we'll get there).

They didn't mention phospholipid exchange therapy to remove toxins from my tissues so nutrients can be absorbed properly.

They didn't mention that constipation = magnesium deficiency.

They didn't connect my post-workout exhaustion to tissue-level magnesium depletion.

They offered pain medication, told me "it takes time to heal," and sent me on my way.

The Progesterone-Myelin Connection Nobody Told Me

While reading about magnesium and myelin, I stumbled into another rabbit hole: progesterone has neuroprotective effects in nerve injury, traumatic brain injury, stroke, and peripheral nerve injury.

Not just "helps with mood" or "balances estrogen."

Progesterone promotes neuroprotection, neurogenesis, and myelin repair.

There are actual clinical trials—like the ProTECT trial in Atlanta studying progesterone for traumatic brain injury. Studies from 2007-2025 documenting how progesterone enhances proliferation and differentiation of oligodendrocyte progenitors into mature myelin-producing cells.

I looked up myelin: "a mixture of protein and phospholipid."

There it is again. Phospholipids.

My accident. Nerve damage. Myelin dysfunction plays a role in:

• Neuroinflammation
• Pain hypersensitivity
• Memory deficits
• Emotional dysregulation

All symptoms I've had since the accident.

Not one doctor mentioned progesterone for nerve repair. Not one doctor mentioned phospholipid exchange therapy for toxic tissue. Not one doctor mentioned tissue-level magnesium deficiency.

But they sure as hell were ready to prescribe antidepressants, pain meds, and tell me my symptoms were "stress."

My New Magnesium Protocol: Months of Loading Because My Tissues Are Empty

Bowles' magnesium protocol isn't "take 400mg and call it a day.

It's a 12-month tissue-loading protocol because blood levels are meaningless:

• Months 1-6: 500mg twice daily (1000mg total)
• Months 7-10: 750mg twice daily (1500mg total)
• Months 11-12: 1000mg twice daily (2000mg total)

Monitor: Heart rate and stool consistency. If you get loose stools or heart irregularity, lower the dose slightly.

BONUS POINT: If you're constipated, you're definitely magnesium deficient.

Constipation = magnesium deficiency.

This is documented in NHANES studies with 9,519 participants showing low magnesium inversely associated with constipation.

Why Such High Doses?

Because your tissues are deficient, not just your blood. You're feeling depleted of intracellular stores in muscle tissue, nerve tissue, and bone tissue. That takes time and consistent loading.

Also: magnesium absorption happens in the small intestine and colon.

If you have gut inflammation (which most people do from processed foods, alcohol, stress), you're not absorbing efficiently. If you're eating processed foods, drinking alcohol, or have leaky gut, you're blocking absorption even while supplementing.

You need higher doses for longer to overcome absorption issues and actually saturate your tissues.

For those that follow me:

The Melatonin Journey Update: Why I'm Calm But Mentally Drained

Today is my birthday, and I'm writing this because I waited to post to give you guys an update on my periods. I've been on Bowles' high-dose melatonin protocol for a few weeks now (from his other book, where he argues melatonin controls all other hormones, including testosterone).

How I feel: Much better. More calm. Less reactive. Emotionally regulated. My blood amount has subsided. I feel less froggy, less paleness and headaches!! What an accomplishment. 

What I'm noticing:  I don't feel overly exhausted like I used to. My menstrual cycle changed from 28 to 30 days. My hair isn't covering by bed and pillowcase. 

Next cycle focus: I'm feeling mentally drained, which i think its because I'm not eating enough protein and my gums are inflamed. I got my gums to get pink for one day this month. I have to figure out what I'm doing that's causing them to inflame. 

The Bottom Line

I am not broken.

I am magnesium-deficient.

My tissues are toxic.

My hormones are tanking because I don't have the minerals required to produce them.

My nerves are damaged and can't repair because nobody told me about progesterone and magnesium for nerve regeneration.

If feel like shit after working out because exercise depletes magnesium through sweat, urine, and energy metabolism—and you're not replacing it.

If you're constipated, it's because magnesium deficiency literally prevents your colon from moving waste.

And nobody's connecting the dots because there's no pharmaceutical profit in you healing yourself with $15 supplements and self-education.

So read.

Track your symptoms.

Question expensive treatments.

Start the magnesium protocol.

And share what you learn.

Because the medical system isn't coming to save us. But we can save ourselves—one PubMed study, one self-published book, one $900 IV therapy we can't afford but understand the mechanism of—at a time.
