What is it?
Creatine is a small nitrogenous compound your body makes naturally from three amino acids (glycine, arginine, methionine) — primarily in the liver, kidneys, and pancreas. You also get a meaningful amount from dietary meat and fish (which is why vegetarians typically run lower endogenous stores). Once in circulation, ~95% gets stored in skeletal muscle as phosphocreatine — a high-energy molecule that donates its phosphate group to regenerate ATP from ADP almost instantaneously when cellular ATP demand spikes.
That last sentence is the whole compound in one line. Creatine is not a muscle-building signal. It’s an ATP-regeneration substrate — a cellular energy buffer that keeps the system running when demand temporarily outstrips production capacity. The bodybuilding-culture framing of the past three decades was a marketing accident; the actual biology is universal because ATP demand is universal. Every energetically demanding cellular process — muscle contraction, neuronal firing, immune activation, ion-gradient maintenance, fat oxidation in mitochondria — runs on ATP. Creatine supports them all.
The remaining ~5% of body creatine is distributed across the brain, heart, and nervous system — precisely the tissues that show the most pronounced functional decline with age and that are most sensitive to ATP availability. That’s why the OHM use case for creatine isn’t athletic performance; it’s foundational support for the cellular energy decline that underlies much of what we experience as aging.
What does it do in my body?
The mechanism has two layers worth understanding separately: what creatine does once it’s in the cell, and how it gets into the cell (which most people get wrong).
Inside the cell — the phosphocreatine system
Inside the cell, creatine and phosphocreatine cycle between two states via the enzyme creatine kinase (CK):
- Phosphocreatine + ADP → Creatine + ATP (donates phosphate to regenerate ATP from ADP under demand)
- Creatine + ATP → Phosphocreatine + ADP (recharges the buffer during rest/recovery)
This cycle is faster than mitochondrial ATP production by orders of magnitude — phosphocreatine donates its phosphate in milliseconds, where new ATP from oxidative phosphorylation takes seconds. So during intense demand (sprint, neuronal firing burst, immune-cell activation), phosphocreatine is the immediate buffer; mitochondrial ATP production catches up behind it. Saturated intracellular creatine stores = larger buffer = more sustained capacity to handle demand before performance falls off.
The downstream effects (three mechanisms for body composition)
When intracellular creatine is well-supplied across the body, three distinct mechanisms support a leaner metabolic phenotype:
-
ATP availability driving basal metabolic rate. Tired cells store fat; energized cells burn it. When mitochondria are producing ATP efficiently — which the phosphocreatine system supports by absorbing the demand spikes — basal metabolic rate (the rate at which cells consume energy at rest) stays higher. A cell running at full energy availability is willing to oxidize stored fat. A cell running on depleted ATP is in conservation mode, defending its energy stores. [established cellular bioenergetics]
-
The futile creatine cycle in adipose tissue. A 2015 landmark Cell paper from the Spiegelman lab (Kazak et al., Cell 163, 643–655; PMC4656041) described what they termed the futile creatine cycle in beige and brown adipose tissue: creatine drives mitochondria in metabolically active fat cells to run hotter, consuming more energy as heat. When the researchers genetically knocked out creatine specifically in fat cells, the mice gained weight and became insulin resistant — apparently because they could no longer regulate thermogenesis properly. Extended by Sun et al. 2021 Nature (CKB controls futile creatine cycling in thermogenic fat). Honest caveat: a 2022 Nature Metabolism critical-assessment paper has questioned the magnitude of this effect in humans ``, so OHM’s tier is “mechanism well-established in rodent models + tissue physiology; magnitude in human energy expenditure is still under active debate.” The mechanism operates independent of muscle and independent of training — that’s what makes it interesting for the OHM customer who’s running a GLP-1 RA and trying to maximize fat-mass-vs-lean-mass loss ratio.
-
GLUT4 upregulation in skeletal muscle. A study in the Journal of Diabetes looked at participants with one leg immobilized for 2 weeks (a disuse-atrophy model). The immobilized leg lost ~20% of its GLUT4 expression — GLUT4 being the transporter that moves glucose from blood into muscle cells. During rehabilitation, the creatine group ended up with GLUT4 ~40% above their own baseline, while placebo simply returned to normal. More GLUT4 → more efficient glucose uptake into muscle → lower circulating blood glucose → less insulin required → improved insulin sensitivity → energy partitioning shifts away from fat storage and toward fat oxidation.
How creatine gets into the cell — the absorption mechanism most people get wrong
This is the operational insight that determines whether your creatine protocol actually works. Creatine cannot cross the cell membrane passively. It requires a specific transporter protein — SLC6A8 (solute carrier family 6, member 8) — to physically pull it from the bloodstream into the cell. SLC6A8 is sodium-dependent: it uses the sodium gradient across the cell membrane to drive creatine uptake. Without an adequate Na+ gradient on the extracellular side, the transporter doesn’t open effectively. The creatine circulates, reaches the kidney, and gets excreted. [established cell biology]
This isn’t theoretical. Green et al. 1996, Acta Physiologica Scandinavica (DOI 10.1046/j.1365-201X.1996.528300000.x; PMID 8899067) — “Carbohydrate ingestion augments creatine retention during creatine feeding in humans.” Healthy adult men were given 5 g of creatine daily, either in plain water or with carbohydrates. The carb-cogestion group generated an insulin response and augmented creatine retention into muscle tissue compared to plain water. The magnitude varies across the literature; the direction is solidly established.
The mechanism of the insulin effect is three-part:
- Insulin upregulates the Na+/K±ATPase pump → steepens the sodium gradient → drives SLC6A8 more efficiently.
- Insulin stimulates nitric oxide production → vasodilation → better creatine delivery to target tissue.
- Insulin activates mTOR signaling → anabolic state → increased cellular capacity to accumulate osmolytes like creatine.
The dehydration problem reinforces the same picture from a different angle. When you’re dehydrated: plasma volume drops → reduced peripheral blood flow → AMPK activation (the cellular energy sensor) → cells deprioritize non-essential processes including creatine uptake. Dehydration doesn’t just passively reduce absorption; it actively suppresses it through a specific biochemical pathway.
The practical implication closes the loop: the most common creatine protocol — first thing in the morning, fasted, in plain water — is approximately the worst-possible conditions for absorption. Sodium is at its lowest after 8 hours of sleep-driven mild dehydration. Cells are dehydrated. The transporter is sodium-starved. Most of the dose gets excreted.
The “creatine bloating” reframe: the bloating people attribute to creatine is frequently creatine sitting in the gut because the cellular uptake conditions aren’t present. Cells can’t pull it in → it sits in the intestine drawing water osmotically. That’s not a creatine side effect — it’s a timing and hydration problem.
How can it help me?
- Best fit: Adults 40+; anyone on a GLP-1 RA fat-loss protocol; anyone with cognitive-load / sleep-deprivation demands; vegetarians (lower dietary intake); the aging musculature broadly
- Where the science stands: >700 human trials; foundational meta-analyses across muscle, cognitive function, fat-mass reduction, glucose handling. The most-studied supplement in human nutrition.

Is it dangerous? What are the side effects?
Creatine is one of the cleanest-safety-profile supplements in nutrition. Decades of use, hundreds of trials, no documented serious harm at standard doses.
- GI upset / bloating — almost always a timing-and-hydration problem (see §How it works → absorption), not a creatine effect. Fix by taking with a meal + adequate hydration.
- Weight gain in the first 1–2 weeks (~1–2 kg) — this is intracellular water shift as creatine pulls into muscle (creatine is osmotically active in the cell). It’s lean tissue water, not fat. It plateaus after saturation and does not reflect fat gain. Worth noting upfront for the GLP-1 customer who’s watching the scale — there’s a brief scale-up before the long-term fat-loss signal that should not be misread as the peptide failing.
- Kidney concerns — the persistent myth that “creatine damages the kidneys” is not supported by the trial base in healthy adults. There IS a sensible caution for people with pre-existing kidney disease (CKD, history of nephritis, etc.) — talk to your physician first. For everyone else, the safety record is exceptionally clean.
- Trimethylamine N-oxide (TMAO) — some early concern about creatine raising TMAO (a cardiovascular risk marker); recent literature has not borne this out as a meaningful signal at standard doses.
Regulatory status: Generic dietary supplement. Not a peptide. Not a drug. Sold over-the-counter worldwide without prescription.

Typical dosing
The doses and schedules here are for educational and informational purposes only. These peptides are sold for research use only and are not FDA-approved drugs. This is not medical advice. Consult a qualified physician before beginning any protocol.
The protocol that actually works
- Dose: 5 g daily, every single day, no exceptions. Consistency over everything else. Creatine works by saturating the intracellular pool over 2–4 weeks of consistent intake; missing days means the pool never fully charges and you sit in a perpetually subsaturated state where benefits are attenuated.
- No loading phase needed for the OHM use case. The 20 g/day × 5 days “loading” protocol is for athletes who want saturation in 5 days instead of 4 weeks. For aging-foundation use, just take 5 g/day from the start. You’ll feel cellular-energy changes at ~14 days and see body-composition + recovery changes at 3–4 weeks.
- Timing: with a meal containing both carbohydrates and protein. Not a sugar drink — a real meal. The modest insulin response from eggs / yogurt / oatmeal + protein / lunch with rice + chicken / similar combinations is sufficient to activate the Na+/K±ATPase pump and drive SLC6A8 efficiently. The Green 1996 insulin-mediated absorption effect compounds across every dose.
- Hydration: drink 12–16 oz of water 20–30 minutes before dosing. Take creatine into a hydrated system, not a dehydrated one.
- Electrolytes: ensure dietary sodium, potassium, and magnesium are adequate. No specialized electrolyte product is required; this is a foundational nutrition pattern, not a pre-workout supplement need.
- If you trained heavily or used heat exposure first: rehydrate before dosing. AMPK-suppression of creatine uptake is real; don’t fight it.
The mistakes that compromise absorption
- First thing in the morning, fasted, in plain water. The single worst protocol. Sodium lowest, cells dehydrated from sleep, transporter at minimum efficiency. Most of the dose gets excreted.
- Immediately post-workout or post-sauna. Electrolytes depleted through sweat; plasma volume reduced; AMPK active. Wait until you’ve rehydrated and eaten.
- Inconsistent dosing. Saturation requires 2–4 weeks consistent daily intake.
On a GLP-1 receptor agonist (Retatrutide, Semaglutide, Tirzepatide): creatine is the fourth non-negotiable for muscle preservation alongside protein, resistance training, and lowering fasting insulin (see the existing “non-negotiables” section in Retatrutide). The Kazak 2015 thermogenic effect in adipose tissue may also contribute additively to the GLP-1-driven fat-loss signal — mechanism-plausible, not formally trialed as a stack. Timing rule: take creatine with one of your post-injection meals — the insulin-state-dependent absorption mechanism it shares with GH peptides means the morning-fasted-plain-water default isn’t just suboptimal, it’s actively undermining your peptide’s lean-mass-preservation goal.
On MOTS-c: both creatine and MOTS-c support cellular ATP availability through different mechanisms — MOTS-c via AMPK-driven mitochondrial biogenesis, creatine via the phosphocreatine buffer. They’re additive, not overlapping. No interactions; stack freely.
On SS-31 (Elamipretide) + NAD+: the brain/cognitive layer where all three converge. SS-31 stabilizes mitochondrial structure (cardiolipin); NAD+ supplies the SIRT1/PARP redox cofactor; creatine buffers the ATP demand. The full mitochondrial-support stack for the aging-cognitive use case is SS-31 + NAD+ + creatine.
Product quality criteria
- Micronized creatine monohydrate. Particle size matters for gut absorption and reduces the gut irritation that poorly-processed bulk creatine causes.
- Third-party tested for purity / contamination. The supplement industry has variable QA; look for COA-backed product.
- “Beyond those two criteria, creatine monohydrate is creatine monohydrate. The molecule is the molecule.” Don’t pay premium for branded forms (HCl, ethyl ester, buffered creatine, etc.) — the evidence base is on monohydrate. The marketing variants don’t have better mechanistic or trial data; they have better marketing margins.

Creatine is the most studied supplement in human nutrition — and the most underutilized for the OHM customer profile. Originally framed as a “gym supplement,” it’s actually a cellular energy compound that becomes more relevant, not less, as you age. For anyone running a GLP-1 receptor agonist (Retatrutide, Semaglutide, Tirzepatide) for fat loss, creatine is the fourth non-negotiable for muscle preservation alongside protein, resistance training, and lowering fasting insulin. This article covers what the molecule actually does, why most people aren’t absorbing it, how to fix that, and where it sits in the OHM peptide stack.

What the research shows
The compound has the densest human-trial base of any supplement in nutrition. Over 700 human trials; consistent findings across muscle preservation, cognitive function, metabolic regulation, and direct effects on fat tissue at the cellular level. The highlights relevant to the OHM customer:
Muscle preservation in aging adults + body composition.
- 2020 Nutrients meta-analysis — adults aged 50+ on resistance training programs. Creatine group lost significantly more fat mass than placebo with identical training and diet.
- 2024 Journal of Strength and Conditioning Research meta-analysis — 12 RCTs in adults under 50. Creatine group lost ~0.7 kg more fat + reduced body fat percentage by ~1 full point vs controls doing the same training without creatine.
- This is fat loss, not just weight loss — the lean-mass-preservation effect is consistent across the meta-analytic base.
Cognitive support + brain energy metabolism.
- 2024 Scientific Reports — a single high-dose creatine measurably restored brain energy metabolism + cognitive performance during sleep deprivation. The brain is roughly 2% of body weight but consumes ~20% of total ATP; phosphocreatine buffering matters there too.
- Broader creatine-cognition literature (Rae 2003, Watanabe 2002, etc.) supports memory and processing-speed effects, especially under cognitive load or sleep restriction.
- Currently ongoing: a 26-week RCT at a major Canadian university testing creatine supplementation in older adults with mild cognitive impairment.
The aging-biology framing.
- After 40: natural creatine synthesis declines; sarcopenia at 3–8% per decade after 30, accelerating after 60; mitochondrial number and efficiency fall; NAD+ declines. The cellular machinery for ATP production is progressively less efficient, and creatine is the buffer for exactly that demand-vs-production gap. A 2024 narrative review explicitly framed creatine as one of the most underutilized compounds for the muscle-brain axis in aging adults.
