The Connective IssueThe Fascia Institute & Treatment Center Journal
A weekly report from the line of scrimmage of fascia medicine — where grit, recovery, and getting back in the game meet.
The supplement everyone is asking about — and what it can’t do.
Creatine is having a moment. Most of what you’re reading about it is true. Some of it is marketing wearing a lab coat, and one popular claim lands uncomfortably close to home for a fascia clinic.
I get asked about creatine more than any other supplement right now, and the questions have changed. It used to be teenage boys and powerlifters. Now it’s women in their fifties asking about bone, patients asking about brain fog, and — increasingly — people asking whether it will help their connective tissue.
That last one is why I wanted to write this up carefully. There’s a version of the creatine story circulating online that goes: creatine pulls water into your cells, hydrated tissue glides better, therefore creatine hydrates your fascia. It’s a tidy story. I went looking for the evidence behind it, and I want to tell you honestly what I found — including the part where I have to tell you the answer isn’t there yet.
Then, because a few of you have asked what actually makes us different from the last four places you tried: the whole playbook — every test we run before we treat you, and every tool we can reach for once we know. Followed by a patient whose high hamstring problem resolved in two visits, which is the shortest version of that argument I can give you.
Also inside: OxeFit assessments are free for the entire month of September, in New Orleans and Beverly Hills, and September is now eleven days away. And a long-overdue spotlight on Brittany, who has been my nurse for a decade and runs the two most technical programs we have.

Creatine, fascia & hydration: what the evidence shows.
One of the most studied supplements on earth, and one of the most confidently oversold. Here’s the line between the two.
Let me start where I’d start with you in the exam room. Creatine is not a fad and it is not a steroid. It’s an amino-acid derivative your body already makes from glycine, arginine, and methionine, and that you already eat in meat and fish. Roughly 95% of it sits in skeletal muscle, where most of it is stored as phosphocreatine — a rechargeable battery your cells drain in the first seconds of hard effort. Supplementing tops that battery off.
The hydration claim, examined
Here’s the argument you’ve probably seen. Creatine is osmotically active — it pulls water with it. More water in the cell means a better-hydrated, more resilient tissue. Fascia depends on hydration to glide. Therefore: creatine for fascia.
The first half is real. Creatine loading measurably increases total body water. In one small deuterium-dilution study in soccer players, a week of loading added more than a liter of it. That’s the honest explanation for the fast two-to-four-pound gain people see in the first week — it’s water, not fat.
The second half is where it comes apart. The most rigorous study on where that water actually goes used tracer dilution — the reference method for this question — and found that total body water rose without changing the ratio of intracellular to extracellular fluid. The water didn’t preferentially move inside the cells. It went up everywhere, proportionally.

So the popular reassurance that “all the water goes inside the muscle cell, so you won’t look puffy” rests on a weaker measurement method than the study that contradicts it. And the leap from intramuscular water to fascial hydration is a leap nobody has actually measured.
What exists on connective tissue — all of it
I want to be precise here, because this is my field and I’d rather disappoint you than mislead you. No human trial has ever measured creatine’s effect on fascia directly. Not a small one, not a bad one. What exists is this:
A 250% rise in collagen gene expression — in nine people
Muscle biopsies after five days of creatine showed a large increase in COL1A1 messenger RNA (Deldicque et al., J Appl Physiol, 2008). That is the instruction to build type I collagen, not collagen itself. No protein was measured, no tendon or fascia was sampled, the study was five people on creatine against four on placebo, and it hasn’t been replicated in eighteen years. This is a reason to run a study, not a reason to make a claim.
One tendon-injury trial that measured muscle
Eighteen adolescent swimmers with tendon overuse injuries, randomized (Juhász et al., J Sports Sci Med, 2018). The creatine group lost less muscle during immobilization and got their strength back faster. Real result — but tendon structure and tendon healing were never measured.
One trial that measured tissue stiffness — and found none added
Twenty men, creatine versus placebo, measuring musculotendinous stiffness (Watsford et al., J Strength Cond Res, 2003). Creatine did not increase stiffness; at the highest load it came down slightly. Worth knowing in both directions — it’s evidence against a connective-tissue benefit, and also against the old locker-room worry that creatine makes you more strain-prone.
Cell biology suggesting creatine matters to fibroblasts
Skin cells from patients with a genetic creatine-transporter deficiency show disrupted extracellular-matrix genes, collagens among them (Nota et al., Human Mutation, 2014). That tells us creatine availability matters to matrix biology in a disease state. It tells us nothing about supplementing someone who already has enough.
That sentence is the most I can defend, and I think it’s still a good reason for many of our patients to take it. If you’re coming back from an injury, if you’re over sixty, if you’re hypermobile and losing ground on strength, the muscle argument is enough on its own. It just isn’t a fascia argument, and you should be skeptical of anyone selling it as one.
What creatine is genuinely good at
- Muscle and strength, paired with resistance training — the best-supported effect there is. Meta-analyses in older adults show roughly 1.3 kg more lean tissue than training alone. Note the pairing: creatine without training does very little.
- Holding onto muscle during a layoff — the most underrated benefit, and the one most relevant if you’re in a boot or a sling.
- Brain, under stress — promising and genuinely mixed. The clearest signal is in sleep deprivation and in people with low baseline stores, such as vegetarians. In rested, well-fed omnivores the cognitive trials mostly come back null.
- Women through midlife — women carry lower total-body creatine stores than men — largely a function of muscle mass and dietary intake rather than a concentration deficit — and the strength and lean-mass findings hold up. Bone is the one people overstate: the trials are split, and the honest summary is not proven.
Four myths I can put down
It wrecks your kidneys. A 2025 pooled analysis of 685 trials — roughly 13,000 people on creatine versus 13,000 on placebo — found overall side-effect rates that did not differ — 13.7% versus 13.2%. Creatine studies were somewhat more likely to report stomach upset and cramping, though that difference disappears once you weight by number of participants. A separate 2025 meta-analysis looking specifically at the kidney found no change in measured filtration rate. In people with normal kidney function, this is about as reassuring as a supplement literature gets. If you have chronic kidney disease, one kidney, a transplant, or you’re on a medication that’s hard on the kidneys, that’s a different conversation — have it with your physician first.
It causes hair loss. This traces to a single 2009 study of twenty rugby players that measured a hormone ratio and never once looked at hair. It has not been replicated in the dozen or so hormone studies since — and a 2025 randomized trial finally did the obvious thing and measured hair itself over twelve weeks. No difference.
It dehydrates you and causes cramps. The data run the other direction — a systematic review of heat and hydration studies found no detriment, and an observational study in college football players found fewer cramps among creatine users.
You have to cycle off. No physiological basis. Your own production dips slightly while you supplement and returns to normal when you stop.
One thing worth telling your doctor
Creatine breaks down into creatinine — the same molecule labs use to estimate kidney function. Supplementing can nudge your serum creatinine up and make your calculated eGFR look worse than your kidneys actually are. Measured kidney function doesn’t change, but the number on the report does. So mention it to whoever orders your labs. It can save you a scare, and occasionally an unnecessary workup.
Educational information only, not medical advice, and not a recommendation to start any supplement. Creatine is not appropriate for everyone — particularly in kidney disease, pregnancy, or breastfeeding, where human safety data are inadequate. Talk with your own physician before starting.
Most clinics start with treatment. We start with why.
If you’ve been to four places for the same pain, you’ve probably noticed that each one offered you the thing they happen to own. That’s the problem we built this practice around.
Here is the uncomfortable truth about musculoskeletal medicine: a clinic with one modality will find a way to make your problem fit it. If all they have is a table, you need adjustments. If all they have is a needle, you need an injection. Nobody is being dishonest. The tool just quietly becomes the diagnosis.
“Your hamstring hurts” is not a diagnosis. It’s a location. What we want to know is what’s actually generating it, what your tissue is made of, what your metabolism is doing to your ability to heal, and how you’re loading the area — before anyone touches you.
First we measure
- Metabolic labs — inflammation, vitamin D, B12 and folate, thyroid, hormones, metabolic health. Tissue that can’t heal often has a reason, and it’s frequently one you can fix.
- Genetic testing — specifically where it changes management, which is the only reason to order it. Connective-tissue panels can reframe an entire case and answer questions patients have carried for years. We do not run genetic panels as a routine screen.
- Diagnostic ultrasound — we look at the tissue in real time, while you move it. Much of what goes wrong in fascia is a gliding problem, and watching layers slide under the probe shows you things a standard MRI protocol simply isn’t built to capture.
- Fascial mapping — a hands-on exam technique, not a lab test, for finding where the restriction actually lives. Very often that’s nowhere near where it hurts.
- OxeFit assessment — objective force, symmetry, and movement data. Numbers, not impressions, and a baseline you can re-check later.
Then we pick the tool that fits
- Physical therapy — the foundation. Almost nothing we do holds without it.
- Shockwave therapy — for stubborn tendon and fascial pain that has stopped responding to load alone.
- TECAR — deep tissue temperature and circulation, useful where hands can’t reach and tolerance is limited.
- PEMF — pulsed electromagnetic field therapy, used as an adjunct for pain and recovery.
- Hydrodissection — ultrasound-guided fluid used to separate fascial layers and free entrapped nerves. This is the one most patients have never been offered anywhere else.
- Prolotherapy — for lax, unstable, chronically irritated attachment sites.
- High-dose PRP — concentrated platelets from your own blood, prepared at higher concentrations than a standard office kit produces, for cases that need a real biologic push.
That’s the whole argument. Measure first, then choose — from a bench deep enough that the choice actually means something. What follows is what it looks like when it works.
Not every option listed is right for every patient, and several are not appropriate for some conditions. Prolotherapy, PRP, and hydrodissection are not FDA-approved for these indications and are generally not covered by insurance. What we recommend depends entirely on what the evaluation finds.
A high hamstring, resolved in two visits.
The section above is the theory. This is the same argument, compressed into two appointments and one week — in his mother’s words, not ours.
“Best kept secret!!!! Excellent, amazing and highly recommended! My son… sustained a significant hamstring injury in his upper thigh (right below the glutes), a more difficult recovery area that requires longer healing time. Because of the injury location, my son had two visits. First visit gave immediate relief with some lingering effects. Second visit — absolute relief. This all occurred over a one week period. Amazing!”
Google Review · Mother of an athlete treated at The Fascia Institute
She has the location exactly right, and it’s the whole story: upper thigh, right below the glutes. That’s the proximal hamstring, where the tendon anchors to the sitting bone — and it is one of the most reliably mismanaged injuries in sports medicine. It hurts most when you sit still. It aches on the drive home. It does not behave like the mid-belly hamstring strain everyone is trained to look for.
So it gets treated as one. Stretched, rolled, rested. Sometimes for a season. For young athletes it’s often longer, because the assumption is that they’ll simply grow out of it.
Stretching a proximal hamstring problem often makes it worse. Bending at the hip compresses the tendon against the sitting bone, so a hamstring stretch adds the exact load the tissue can’t tolerate. That’s the trap: the intervention that feels most obvious is the one making the least progress.
What changed the outcome here wasn’t a secret technique. It was looking first — putting an ultrasound probe on the area and finding what was actually generating the pain instead of assuming — and then choosing the intervention that matched what we found. Note what she reports from visit one: immediate relief, with some lingering effects. That’s what it looks like when you’ve identified the right structure but the tissue still needs a second pass. The second visit wasn’t a new theory. It was finishing the job.
And the phrase I’d underline is the one she buried in the middle: a more difficult recovery area that requires longer healing time. She’s right, and she clearly knew it going in. That expectation — months, maybe a lost season — is the standard one for this injury, and it’s why the week mattered as much as the relief did.
We’re not going to pretend every case resolves this fast, because they don’t, and any clinic that tells you otherwise is selling something. Plenty of what we treat is measured in months. But when something has dragged on for a year and then resolves in two appointments, the difference is almost never how hard anyone worked. It’s that somebody finally asked the right question at the start.
Shared with permission and edited only to remove identifying initials. Individual results vary; this is one patient’s experience, not a promise of outcome. High hamstring injuries differ widely in severity, and many take considerably longer than this one did.
The assessment we start with is free next month.
Everything above rests on measuring before treating. For the entire month of September, the measuring part costs you nothing — at both locations.
Most people have no objective idea how their body is performing. You know whether something hurts. You don’t know whether your left side is quietly doing sixty percent of the work, whether your force production has dropped since last year, or where you’re compensating in a way you can’t feel.
OxeFit gives you that in numbers. It measures how you actually produce and absorb force — strength, balance, symmetry between sides, movement quality — and turns it into a baseline you can act on and re-check later. It’s the difference between “my knee feels weird” and knowing exactly which side is under-loading and by how much.
- Athletes and weekend warriors — know your asymmetries before the season finds them for you.
- Anyone coming back from injury — objective proof of where recovery actually stands, not just how it feels.
- Hypermobility and connective-tissue patients — a stability and control baseline that’s notoriously hard to capture any other way.
- Anyone over 40 — the earliest strength and balance changes are the ones worth catching.

Brittany Estrade, RN, BSN, CRRN
Every patient asks who’s doing their injection. Very few clinics can answer “the same nurse who has been here for a decade.”
I hired Brittany ten years ago for her rehabilitation nursing background, and that turned out to matter more than I understood at the time. She has since gone and gotten board certified in it — the CRRN after her name is Certified Rehabilitation Registered Nurse, a credential you earn by passing an exam on top of thousands of hours of actual rehab practice. Rehab nurses see the unglamorous middle of recovery — the weeks after the procedure, when progress is slow and patients get discouraged. She came in already knowing what healing actually looks like from the inside, which is not something you can teach someone who has only ever assisted with the procedure itself.
She is organized to a degree I’ve stopped trying to match, and particular about patient care in the way you want someone to be particular when they’re handling your blood. Those two traits are why she ended up running the things she runs.
What Brittany does
She is our high-dose PRP expert — the most technically demanding preparation we do, where the concentration and handling of your own platelets determines whether the treatment is worth having at all. She also runs our entire IV program. And she is licensed in California as well as Louisiana and travels to Los Angeles to deliver care there — which means the patient who flies in from out of state sees the same person, doing it the same way, in either city.
That last part deserves more attention than it usually gets. We treat patients from across the country, and the thing that quietly breaks down in that kind of care is continuity — you build a relationship with a clinic and then get whoever is available. Brittany is the reason that doesn’t happen here. Whichever coast you’re on, it’s her.
Ten years is a long time in medicine. I’m lucky she’s stayed.
Before you buy the tub.
If you and your physician have decided creatine makes sense for you, here’s the whole protocol. It fits in a paragraph.
Buy plain creatine monohydrate. Not HCl, not buffered, not ethyl ester — none of them have beaten monohydrate in a head-to-head, and ethyl ester is actually worse. Look for a third-party purity seal such as NSF Certified for Sport or Informed Sport. It should be one of the cheapest things in the store.
Take 3–5 grams a day. Skip the loading phase. Loading gets you to the same place about three weeks sooner and is the main reason people report bloating and stomach upset. Daily consistency matters more than timing.
Then be patient and pair it with resistance training, because that pairing is where nearly all of the proven benefit lives. Creatine on the couch does very little.
And the one I’d ask you not to skip: tell whoever draws your labs that you’re taking it. See the cover story for why.
Not medical advice. Talk with your own physician first — particularly if you have kidney disease, are pregnant or breastfeeding, or take medications that affect the kidneys. For anyone under 18, that conversation belongs with their pediatrician.
