Creatine Shmeatine?

Most Supplemented, Most Misunderstood

Why the answer isn't as simple as "5 grams a day" — and why your mineral foundation matters more than what's in your supplement stack.

TL;DR

• Creatine is a naturally occurring molecule synthesized by your body from three amino acids, and found abundantly in red meat and fish — your body makes roughly 1–2 grams of it daily on its own
• Its primary job is rapid energy regeneration — acting as a phosphate "emergency fund" for your muscles and brain during high-demand moments
• Creatine deficiency shows up as persistent muscle fatigue, brain fog, poor recovery, and reduced physical output; low dietary intake from avoiding animal foods accelerates this
• Dr. Ben Bikman and Dr. Paul Saladino make compelling, research-backed cases for supplementation: sharper cognition especially under sleep deprivation, improved bone density, muscle preservation with aging, blood sugar regulation, and early Alzheimer's protection
• Dr. Jack Kruse calls supplementation a tool for "smooth brainers and chimps" — and from a quantum biology standpoint he raises serious concerns: most synthetic creatine carries deuterium (a heavier form of hydrogen that disrupts cellular energy production) and manufacturing residues that most purity certificates don't even test for
• Creatine supplementation without a verified mineral foundation can actively drain magnesium, distort the mineral ratios your cells depend on, and turn a promising supplement into a stressor on an already taxed system
• Hair Tissue Mineral Analysis (HTMA) can reveal whether your internal environment is even capable of utilizing creatine effectively — or whether you're adding more noise to an already broken signal
• If you're eating quality animal protein and optimizing your light environment, your body may already be synthesizing and utilizing creatine more efficiently than any powder can replicate
• The supplement debate is a distraction from the real question: is your mitochondrial environment built for it?

There are few supplements that generate quite the same mix of passionate advocacy and equally passionate ridicule as creatine. Walk into any gathering where Bitcoiners, carnivores, and biohackers intersect and you'll find the believers clutching their Thorne monohydrate like a sidearm and the skeptics, led by none other than Dr. Jack Kruse, who refers to creatine enthusiasts as "smooth brainers" operating at chimp-level biology.

The truth, as usual, lives somewhere in the rabbit hole — and it's more interesting than either camp acknowledges.

Let's go in...

What Happens When You Don't Have Enough — or Take Too Much

Before we argue about powders, let's talk about what creatine deficiency actually looks like in the body, because most people have never connected their symptoms to this particular molecule.

People with chronically low creatine — whether from inadequate animal protein intake, impaired synthesis, or both — tend to present with persistent muscle fatigue that doesn't resolve with rest, stubborn brain fog, poor short-term memory, slow recovery after exercise, and a general feeling of "heaviness" in the limbs. Vegetarians and vegans are particularly affected: studies show their muscle creatine levels run 20–30% lower than meat-eaters, with measurable impacts on both physical performance and cognition. As Dr. Ben Bikman, a biomedical scientist and professor of cell biology at BYU, notes in his Metabolic Classroom lecture on creatine, this is a population for whom supplementation "could be an absolute game-changer from biceps to brains."

On the other end, creatine in excess — particularly from poorly sourced supplements — can cause water retention (especially with monohydrate), GI distress at high doses, and, in certain biochemical contexts we'll get into, can actively work against the mineral balance your cells depend on.

The sweet spot, as with most things in biology, is context-dependent. And the context is almost never discussed.

What Creatine Actually Is (And Why You Already Have It)

Creatine is a naturally occurring compound produced by your liver and kidneys from three amino acids: arginine, glycine, and methionine. Your body makes roughly 1–2 grams of it per day. You can also get it from animal foods — a pound of beef or salmon delivers approximately that same 1–2 gram daily amount.

Here's where it gets genuinely fascinating.

Bikman describes creatine's primary role as "a rapid response energy buffer in cells, especially in cells with high energy demands like the exercising muscle or even the neurons of the thinking brain."

To understand what that means, you need a brief word on ATP — adenosine triphosphate — which is essentially your cells' energy currency. Imagine every cellular action, from a muscle contraction to a neuron firing a thought, as a purchase. ATP is the money that funds it. When ATP makes that purchase, it breaks a chemical bond, loses a phosphate group, and becomes ADP (adenosine diphosphate) — a spent bill, if you like. The problem is that ATP stores run out fast during intense activity. You might deplete them in seconds.

This is where creatine steps in.

Once phosphorylated — meaning it picks up a phosphate group — creatine becomes phosphocreatine (PCr). Phosphocreatine holds a spare phosphate in reserve, ready to donate it back to spent ADP and instantly regenerate ATP. The enzyme that makes this happen, creatine kinase, is extraordinarily fast. Think of phosphocreatine as a backup generator that kicks in the moment the main power grid flickers. That's not a gym-bro concept. It's the biochemistry operating in every one of your cells, right now.

The Case for Supplementation: Bikman and Saladino Make Their Move

If you've spent any time in the ancestral health space, you know Paul Saladino — the cardiologist-turned-animal-foods advocate who built a following defending nose-to-tail carnivore eating. His relationship with creatine supplementation is, to put it mildly, enthusiastic. He's spoken publicly about taking up to 20 grams on days following poor sleep — a protocol that actually has emerging research support.

A 2024 paper published in Scientific Reports found that a single high dose of approximately 0.35g per kilogram of body weight — which works out to roughly 20–30 grams for most adults — meaningfully boosted memory and processing speed in sleep-deprived individuals. Effects kicked in around three hours after dosing and lasted up to nine hours. For the Bitcoiner who stayed up until 3am in a heated debate about layer-2 solutions, that's not nothing.

Saladino also highlights creatine's bone health data — the 10-gram dose range has been studied specifically for bone mineral density — and makes the point that women are dramatically underexposed to this research.

"Most women have never heard of creatine," he notes. "And especially for women, it's such a valuable supplement."

Bikman's breakdown is more systematic, and covers ground that most supplement conversations miss entirely.

Muscle and Recovery. Creatine is the most well-validated supplement for high-intensity, short-duration performance. Studies show it can increase strength by up to 10% and power output by up to 15% compared to placebo. A 1999 study found creatine users gained 2–4 pounds more lean mass than the placebo group after 12 weeks of resistance training — some of that is water drawn into muscle cells alongside the creatine, but lean tissue gains were real. On recovery: a 2004 report found creatine reduced markers of muscle damage by 20–40% following eccentric exercise — the "lowering" portion of a movement, which creates more micro-tears than the lifting phase, and which most people feel two days later when they can't walk properly after leg day.

Brain Function. Your brain burns roughly 20% of your body's total energy — an extraordinary proportion for an organ of its size. Neurons depend on the phosphocreatine system for rapid energy top-ups, the same way muscles do. A 2007 study found that vegetarians given just five grams of creatine daily for six weeks showed measurably better working memory and processing speed. Evidence is also building for Parkinson's neuroprotection, recovery support after traumatic brain injury, and early-stage Alzheimer's — which Bikman frames not as a plaque disease but as a brain energy crisis, making the ATP-supporting role of creatine a logical intervention. A 2025 study showed creatine slowed cognitive decline in early-stage Alzheimer's patients.

Metabolic Control. Creatine phosphate appears to enhance something called GLUT4 translocation — GLUT4 is essentially a doorway on the surface of muscle cells that lets glucose in from the bloodstream. Normally, that door only opens in response to insulin or exercise. Creatine phosphate helps open it through a third pathway, independent of both. The practical result is better blood sugar control, both in athletes and in sedentary people with type 2 diabetes. The mechanism is clean and makes biological sense.

Cellular Protection. Beyond ATP, creatine does things most people never hear about. It stabilizes the fatty structure of cell membranes — making them more resistant to damage under stress. A review published in Physiological Reviews in 2000 showed creatine integrates into the lipid bilayer (the double-fat-layer wall of the cell) in a way that reduces the leakage of harmful ions and preserves cell integrity. Creatine also appears to boost antioxidant enzyme activity and directly neutralize some reactive oxygen species — the molecular "sparks" that damage proteins, fats, and DNA inside your cells. It also influences gene expression, upregulating growth factors that drive muscle protein synthesis and repair. In Bikman's framing, creatine is "a multi-tool for the cell" — not merely a performance enhancer but a cellular protector.

But Muh Kidneys...

On the kidney damage myth — which refuses to die — the confusion stems from mixing up two different molecules: creatine and creatinine. Creatinine is simply the waste product left over after creatine has done its job — your kidneys filter it out and it leaves in the urine. When you supplement creatine at high doses, your body naturally produces more creatinine as a byproduct.

A standard blood panel may flag this as elevated, which some doctors interpret as a kidney concern. But elevated creatinine from creatine supplementation is just evidence that the molecule is being metabolized — it's the exhaust from a revving engine, not a sign the engine is damaged. Kidney filtration capacity itself was tracked in a 2008 study following athletes taking up to 20 grams daily for five years, with no deterioration found. For anyone with a pre-existing kidney condition, a conversation with your doctor is still warranted. For healthy people, the data is clear.

Enter Dr. Kruse: "Creatine Is for Smooth Brainers"

If you follow Jack Kruse on X, you know he is not quietly neutral on this topic. In a thread posted May 2025, Kruse wrote:

"Beware the hidden risks of creatine supplementation. Major brands rarely disclose levels of deuterium, dicyandiamide (DCDA), or triazines, toxic residues from manufacturing that slip through even third-party testing."

This is not contrarianism for the sake of it. Kruse's concerns operate at a level the supplement industry — and most of functional medicine — simply isn't looking at.

Here's the argument unpacked, as clearly as possible.

The Deuterium Problem

If you've been with this newsletter for a while, you've encountered deuterium before — we covered it in depth in a previous issue. To recap briefly: deuterium is a naturally occurring but heavier form of hydrogen. Regular hydrogen has one proton and one electron. Deuterium has an extra neutron, making it roughly twice as heavy. Inside your mitochondria — the cellular power plants responsible for producing ATP — there is an extraordinarily precise proton transport system. Protons (hydrogen ions) are pumped across the inner mitochondrial membrane and flow back through a protein complex called ATP synthase, which spins like a molecular turbine and uses that flow to build ATP. This proton movement, known as the Grotthuss mechanism (essentially proton "hopping" through a chain of water molecules), is calibrated for regular hydrogen. Deuterium, being twice as heavy, throws off that mechanism — like putting a larger, mismatched ball bearing into a precision gear system.

Most commercial creatine is synthesized through industrial chemical reactions that do not exclude deuterium. As Kruse stated plainly in an April 2025 thread:

"All creatine has tons of D in it. Creatine from food doesn't." This is a distinction no mainstream creatine conversation addresses.

DCDA and Triazines: The Residues Nobody Tests For

The manufacturing process for synthetic creatine typically involves reactions with dicyandiamide (DCDA) and sarcosine under industrial conditions. This process leaves behind trace residues of DCDA and related compounds called triazines. These aren't classified as toxins under standard supplement regulations, and most purity certificates don't even test for them. Kruse's concern — grounded in structural physics — is that these molecules have specific light-absorption profiles in the UV range (200–300 nanometers) and may interact with the ambient non-native electromagnetic field (nnEMF) environment — Wi-Fi, 5G — in ways that amplify their biological disruptiveness. The interaction could generate reactive oxygen species and interfere with the ultra-weak photon emissions (essentially biophotons — light signals your cells use to coordinate cellular activity) that your mitochondria rely on for internal communication. A 2017 study confirmed that EMF alters the optical properties of biological tissue. If those optical properties are further disrupted by triazine residues resonating in an EMF-saturated environment, the downstream effects on cellular signaling could be significant.

Kruse's conclusion was unambiguous:

"So if you are a tech abuser, stay away from these products. Employ the precaution principle."

If you're a Bitcoiner running multiple screens in a 5G-dense urban environment, that sentence was directed at you personally.

Who among us is NOT a "tech abuser?" Few.

The Glutathione Angle

In a September 2025 thread, Kruse made a claim that stopped a lot of people mid-scroll:

"I wonder when people are going to realize that creatine powder has the same effect on endogenous glutathione recycling as Tylenol."

The two "cats" he refers to?

Glutathione is your body's primary antioxidant and detoxification molecule — what keeps your cells' cleanup crews running efficiently. Tylenol's well-documented danger in excess is its depletion of glutathione, which is why emergency rooms exist specifically for acetaminophen overdose. Raising that comparison in the context of a widely celebrated supplement is not a casual observation.

In this post, Kruse references the epiphany reached by functional hormone expert, Tom Simmons, @yoursimmo11 on X:

Creatine as Signal Noise

Kruse's deepest critique may be this one, posted April 2025:

"Creatine offers no information to the body on temperature, light, or oxygen when you take it, so it becomes NOISE and ruins the fidelity of the signal mtDNA is looking for."

Your mitochondrial DNA is not simply running chemistry — it's reading its environment. Light spectrum, temperature gradients, oxygen levels — these are the upstream signals that regulate energy production. Exogenous (outside the body) creatine from a powder bypasses that signaling entirely. In a well-optimized system — morning sunlight, grounding (direct bare-skin contact with the earth, which equalizes the body's electrical charge and supports antioxidant electron flow), low nnEMF, quality animal foods — the TCA cycle, which is the core metabolic engine your mitochondria use to generate energy, operates fully and creatine becomes, in Kruse's framing, "superfluous." When that cycle isn't running well — when the light-sensitive protein complexes inside mitochondria that handle electron transport are impaired by poor environment or heavy metal interference — supplemental creatine becomes a chemical bypass rather than a solution. "Cytochrome proteins are heme-based," Kruse wrote in a separate thread, "so when they are destroyed you believe in creatine and carbs because you cannot use the TCA cycle and you must use Warburg metabolism and the PPP — you think like a chimp." Provocative? Absolutely. Technically defensible? More than his critics acknowledge.

The Mineral Status Dimension: Where HTMA Becomes Essential

Here's where the conversation shifts from theoretical to something you can actually act on.

No magnesium, no functional creatine cycling. This is not a minor caveat — it's the biological prerequisite for creatine to do what you're taking it to do.

Creatine's entire energy-regenerating mechanism depends on magnesium. The phosphocreatine reaction cannot happen without magnesium ions stabilizing the phosphate group throughout the transfer.

The problem is that a large portion of people under chronic stress are functionally magnesium-depleted — even if a standard blood test says their levels are "normal." Blood magnesium is tightly regulated by the body, which will pull magnesium from bones, muscles, and other tissues to keep blood levels looking fine. By the time blood magnesium actually drops on a lab report, you're already significantly depleted at the tissue level where it matters.

When someone in this state adds creatine, the supplement pulls additional magnesium into the mitochondria to keep the reaction running. The fluid surrounding the cell machinery gets even more depleted.

Beyond magnesium, creatine draws water into cells. In a well-mineralized, healthy cell, this is one of creatine's beneficial effects. In a cell already struggling with disrupted sodium-to-potassium balance — which governs cell membrane function, nerve signaling, and the body's basic electrical architecture — the extra water pressure can work against you. Minerals that should be cycling through the system get locked in the wrong compartments.

This is why knowing your mineral ratios before supplementing creatine is not optional information — it's the prerequisite question. And the only functional tool that gives you a 2–3 month picture of your actual tissue mineral status, not just a blood snapshot, is Hair Tissue Mineral Analysis.

HTMA works because hair, as it grows, incorporates minerals and metals from your blood supply — making it a continuous biochemical record, a rolling log of what your body has been doing metabolically. Think of it as a blockchain of your biology: immutable, sequential, and revealing patterns that a one-time blood draw simply cannot capture.

What HTMA shows that standard panels miss: your calcium-to-magnesium ratio (which governs nervous system reactivity and sleep quality), your sodium-to-potassium ratio (which reflects adrenal function, stress adaptation, and cell membrane integrity), your oxidative type (whether your metabolism is running fast, slow, or somewhere between), and your toxic metal burden — mercury, lead, cadmium, arsenic — all of which compete directly with the mineral cofactors creatine requires to function. You cannot know whether creatine is helping or hurting without knowing this picture first. Feeling fine on a supplement is not the same as the supplement being appropriate for your system.

Food vs. Powder: The Question Kruse Actually Answers — and the One He Raises

When you eat quality animal protein — grass-finished red meat, wild-caught fish, organ meats — you're getting creatine the way your biology was designed to receive it: embedded in a protein matrix alongside the mineral cofactors, structured fats, and natural water that allow for appropriate absorption and metabolism. No manufacturing residue. No deuterium contamination from industrial reactors. No synthetic byproducts.

But here's where Kruse's position gets more specific — and more interesting — than most of his detractors realize.

Kruse doesn't just say eat animal food and skip the powder. He has a clear hierarchy, and fish sits at the top of it. The reasoning isn't arbitrary. Wild-caught fatty fish, particularly cold-water species, are among the most concentrated sources of DHA (docosahexaenoic acid) in the human diet. DHA is the specific long-chain omega-3 fatty acid that makes up a critical portion of your brain's structure and the membrane of every cell in your body. It's the molecule that allows your cell membranes to remain fluid, flexible, and electron-rich — a property that Kruse ties directly to how well your mitochondria can communicate with their environment through light. In short, he considers fish the superior dietary "antenna" for quantum biological function, not merely a protein source.

Fish also delivers creatine in a genuinely food-derived, non-industrially synthesized form — exactly what Kruse argues is missing from every container of monohydrate on the market.

This is a compelling case. And it immediately raises a question that anyone paying attention should be asking.

The Mercury Problem Nobody Wants to Sit With

If Kruse is right that fatty fish is the superior vehicle for natural creatine delivery, DHA, iodine, selenium, and the mineral matrix your mitochondria need — and the research largely supports this — then a practical counter-concern has to be addressed honestly: methylmercury.

Mercury contamination in fish is not a fringe concern. Methylmercury — the organic, lipid-soluble form of mercury that accumulates in aquatic food chains — crosses the blood-brain barrier with relative ease and has well-documented neurotoxic effects at sufficient exposure levels. Its particular biological nastiness comes from the fact that it disrupts selenoproteins — the selenium-dependent enzymes your body relies on for antioxidant protection and thyroid function, including glutathione peroxidase.

So you have Kruse advocating fish as the ideal food, and methylmercury as a legitimate reason for pause. How do you square that in a real family's life — with a spouse, a teenager who trains, jobs, and no intention of relocating to a pristine coastal environment?

The Selenium Buffer: Why Species Selection Is the Variable That Matters Most

The nuance that most mercury-fear content misses is this: selenium and mercury have an extraordinarily high chemical affinity for each other. In whole fish — as opposed to isolated fish oil supplements — selenium is present in the same food matrix as any mercury that species has accumulated. Research by Dr. Nicholas Ralston at the University of North Dakota established that what matters toxicologically is not the absolute amount of mercury in a fish, but the ratio of selenium to mercury at the molecular level. When selenium is present in greater concentration than mercury — which is true for the vast majority of small, short-lived, cold-water species — the selenium effectively outcompetes the mercury for the binding sites that would otherwise disrupt your selenoproteins. The selenium surplus keeps your protective enzymes running even after the mercury has been bound and rendered largely inert.

This protection disappears when you strip away the food matrix. A fish oil supplement that has removed the intact protein and mineral context leaves any mercury residue more bioavailable, not less. Whole fish is protective in a way that isolated oil is not — which is itself an argument for food over supplement that goes well beyond the creatine conversation.

The practical implication is that species selection matters far more than fish avoidance. The safest and most nutrient-dense choices are small, short-lived, low-food-chain species: sardines, anchovies, wild-caught oysters, mussels, herring, and mackerel. Because these animals live shorter lives and occupy lower positions in the ocean food chain, they accumulate far less mercury while delivering concentrated DHA, selenium, zinc, iodine, and naturally occurring creatine. These are the species that should anchor a family's regular rotation.

Wild-caught salmon and trout occupy a reasonable middle tier — higher in the food chain, but still well within sensible consumption for most people. The species to genuinely limit or avoid are the large, long-lived predators: tuna, swordfish, shark, and Chilean sea bass. These animals have had years or decades to bioaccumulate mercury up the food chain, and no selenium context changes that calculus enough to justify making them dietary staples.

The Light, Grounding, and Mineral Context

There's a deeper layer here that's easy to miss if you're tracking only the toxin rather than the resilience of the host receiving it.

Your body's ability to handle trace methylmercury exposure isn't fixed — it scales with the robustness of your detoxification infrastructure. Glutathione, your body's master antioxidant and detox molecule, is selenium-dependent. Melanin — the pigment produced in skin through UV exposure — has a documented affinity for heavy metals and functions as a biological chelator embedded in your own tissue. The metallothionein proteins that serve as your body's backup system for binding and exporting toxic metals are zinc- and copper-dependent. If your zinc-to-copper ratio is off — something an HTMA will reveal clearly, and standard blood work will miss entirely — that entire backup system is operating at reduced capacity.

Which means: if your nnEMF exposure is high, your glutathione is already suppressed. If you're avoiding the sun, you're not building the melanin-based chelation infrastructure your skin and nervous system use to sequester heavy metals before they cause damage. If your mineral ratios are dysregulated, the metallothionein pathway that should backstop all of this is weakened further.

The methylmercury risk in a sardine eaten by someone with optimized mineral status, regular sun exposure, grounding habits, and clean water is genuinely different from the same sardine eaten by someone who is mineral-depleted, nnEMF-saturated, and chronically stressed. Toxicity is not just about the molecule — it's about the environment the molecule enters.

This is not a license to eat swordfish daily and call it ancestral eating. It is an argument for building the biology that treats trace mercury as a manageable input rather than an inevitable insult. Small fatty fish, eaten regularly within a well-supported mineral and light environment, is a genuinely different proposition than the mercury-fear narrative suggests.

One more practical note worth making: anxiety about mercury contamination can itself become a biological problem. Chronic dietary restriction and food-related stress elevate cortisol, which depletes magnesium, selenium, and zinc — the very minerals you need to keep heavy metal detoxification pathways open. Stress about toxins is not a neutral act at the cellular level. Sometimes the most protective thing you can do is make a reasonable, informed choice, eat the sardines, and trust the body you've actively built to handle it.

The ancestral argument is clean: if you're prioritizing small cold-water fish as a dietary staple, eating nose-to-tail from quality animal sources, attending to your morning light, and keeping your mineral foundation verified and intact, your body may be generating and utilizing creatine more effectively than any powder can replicate — without the manufacturing residues, without the deuterium load, and with a built-in buffering system for the trace contaminants that come with living in the modern world.

The powder is a workaround. Food is the system.

The Reconciliation: Both/And, Not Either/Or

Bikman and Saladino are describing real, well-documented biochemical benefits. Kruse is raising real, physics-grounded risks that the supplement industry has no financial incentive to address. They're not contradicting each other — they're operating at different levels of the same stack.

Bikman and Saladino work at the biochemical level: here's the molecule, here's what it does, here's three decades of research.

Kruse works at the quantum biological level: here's what the manufacturing process puts into that molecule, here's what happens to it in a compromised environment, and here's why fixing the environment should precede introducing the isolate.

The practical synthesis: if your foundation is sound — minerals verified, nnEMF managed, light environment attended to, quality animal protein anchoring your diet — the risk-benefit calculation for a clean creatine supplement shifts more favorably for specific use cases: sleep deprivation recovery, intense training phases, periods of high cognitive demand. If your foundation isn't sound, creatine is at best a bandage and at worst an accelerant on a smoldering mineral deficit.

The question isn't "is creatine good or bad?" The question is "am I a good enough environment to use it well?"

That's a question only your data can answer.

The Bottom Line

Creatine is not the magic powder the gym world sold you, and it's not the unequivocal villain it occasionally sounds like coming from Kruse's feed. It's a powerful, context-dependent molecule whose effects — positive or negative — are heavily shaped by the environment it enters.

If your minerals are depleted, your magnesium is low, and your mitochondria are already running on stress hormones and nnEMF overload, creatine supplementation is unlikely to deliver what you're hoping for — and may quietly deepen what's already broken.

If your foundation is solid and you're eating the animal foods that provide creatine in its natural, food-matrix form, you may not need the powder at all.

And if you're in the messy middle — which most of us are — the answer isn't more guessing. The answer is verification.

Your health is the ultimate long position. Don't run it on assumptions.
