Creatine for Adult Skaters: What the Research Actually Supports
Physiotherapist and skater. Came back to skating at 49 and hasn't stopped.
I get asked about collagen and magnesium regularly in clinic. Creatine comes up less often, which is a little backwards — it’s one of the most heavily studied supplements in sports science, and the research specifically on older adults gives it a stronger evidence base than most of what’s actually trending.
This isn’t a supplement that will help you land anything sooner. What it can do is support the strength training that makes your body more durable for skating — which, for most adults coming back to the sport, matters more than any single trick.
What creatine actually does
Creatine is stored in muscle tissue and used to regenerate ATP, the molecule your muscles burn for quick, forceful effort — the kind of short, explosive output involved in a hard pop, an ollie, or catching yourself out of a wobble. Supplementing increases the amount of stored creatine available for that system, which is the mechanism behind most of its measured effects: slightly more capacity for repeated short bursts of effort, and — more relevantly here — better results from resistance training.
That second part is the one that matters for this audience. Creatine on its own doesn’t build muscle. Paired with regular resistance training, it consistently helps people build more of it than resistance training alone.
What the research in older adults actually shows
Supplement marketing has a habit of overselling thin evidence, so it’s worth being specific about what’s solid and what isn’t.
Lean mass and strength: this is the well-supported part. The clearest summary is a 2017 meta-analysis by Philip Chilibeck, Darren Candow and colleagues in the Open Access Journal of Sports Medicine, which pooled 22 randomized trials with 721 older adults (average ages 57 to 70 across the studies) lifting two or three days a week for anywhere from seven weeks to a year. The people taking creatine gained about 1.4 kg more lean tissue than the placebo groups and made larger gains in chest-press and leg-press strength. A 2021 follow-up analysis by the same group found the effect held regardless of whether people loaded, what maintenance dose they used, or whether they only took it on training days. That is more consistency than most supplements marketed to this age group can show.
Bone density: this is the overstated part. Despite some of the current wellness coverage implying creatine supports bone health broadly, the trial evidence specifically on bone mineral density in older adults is weak to neutral. A 2018 meta-analysis by the same Saskatchewan group (Forbes, Chilibeck and Candow, in Frontiers in Nutrition) found no extra bone-density benefit from adding creatine to resistance training at the hip, femoral neck, spine or whole body, and the largest trial since — a two-year randomized study of 237 postmenopausal women published in Medicine & Science in Sports & Exercise in 2023 — again found no difference in bone mineral density, though it did preserve some measures of bone geometry at the femoral neck that relate to bending strength. Any benefit, in other words, looks indirect or structural rather than a direct gain in density. If bone health is your primary concern, weight-bearing training and your doctor’s guidance matter far more than this supplement does.
Who it actually helps: the benefit shows up specifically for people who are also doing resistance training. If you’re not lifting anything regularly — and plenty of adult skaters aren’t, between skate sessions and the rest of life — creatine alone isn’t going to do much for you. It’s an amplifier for a training stimulus, not a substitute for one.
The practical basics
Creatine monohydrate is the form almost all of the research is based on, and it’s the one worth buying — more expensive “advanced” forms don’t have better evidence behind them. A typical maintenance dose is in the range of 3 to 5 grams daily, taken consistently; timing relative to your workout or skate session matters far less than most product marketing suggests. Some people do a short loading phase of higher daily doses for about a week to saturate muscle stores faster, but it’s optional — skipping it just means it takes a few weeks longer to reach the same place.
Drink enough water. Creatine draws some water into muscle cells, and staying adequately hydrated is the main thing that keeps that from feeling uncomfortable.
Who should talk to a doctor first
Anyone with existing kidney disease, or on medications that affect kidney function, should check with their doctor before starting creatine. The International Society of Sports Nutrition’s 2017 position stand found no compelling evidence that creatine harms kidney function in healthy people, so the concerns you hear in casual conversation are largely overstated — but they’re real enough for people with existing kidney issues that it’s not worth guessing. One practical point even if your kidneys are fine: creatine raises the blood creatinine level that routine kidney-function tests use to estimate filtration, so a standard blood panel can read as a dip in kidney function that isn’t real. Tell whoever orders your blood work that you’re taking it. The same goes if you’re managing any chronic condition or taking regular medication; a quick conversation with whoever manages your care costs you nothing and rules out an interaction you might not think to ask about otherwise.
Mild, manageable side effects — some water retention, occasional stomach discomfort if you take a large dose all at once rather than splitting it — are the most common complaints, and splitting the dose or taking it with food usually resolves them.
The honest summary
Creatine won’t make you skate better by itself. What it does is make the resistance training you’re already doing, or should be doing, somewhat more productive — and for an adult body managing recovery and trying to stay durable enough to keep showing up at the park for years, “somewhat more productive strength training” is a genuinely useful thing to have on your side. It’s not magic, and it’s not useless. It’s a reasonable, well-studied supplement that does one specific job, for the specific group of people actually doing the training it supports.
