Creatine is also one of the most extensively researched supplements, with evidence supporting improvements in strength, power, repeated high-intensity performance, and training adaptations when paired with exercise. It's not just for bodybuilders.

Walkers, hikers, and everyday active people can benefit most when their routine includes hills, intervals, gym work, or carrying loads. This guide breaks down what actually works (and what's mostly marketing), explains how to dose creatine simply, and helps choose a product without overpaying - with safety considerations for people who may need extra caution.[1][2][11][12][33][34]

Health & Wellness Disclaimer

The information in this article is intended for general education and wellbeing and discusses creatine supplementation, including potential benefits, dosing approaches, product selection, and safety considerations for generally healthy adults.

Creatine may not be suitable for everyone. If you have any medical conditions - especially kidney disease or reduced kidney function, high or unexplained creatinine blood results, liver disease, hypertension, or any long-term condition - or if you are pregnant or breastfeeding, under 18, have a history of bipolar disorder, or are taking prescription medicines (particularly those that may affect kidney function), you should speak to your GP, pharmacist, or another qualified healthcare professional before starting creatine or changing your supplement routine. If you have been advised to limit protein, fluids, or certain supplements for medical reasons, do not start creatine without professional advice.

This article does not provide medical advice and should not be used as a substitute for professional healthcare. Supplements are not regulated in the same way as medicines in the UK, and product quality can vary between brands. Always follow the manufacturer's directions, do not exceed recommended doses, and stop use and seek medical advice if you experience concerning symptoms. If you develop urgent symptoms such as chest pain, a severe allergic reaction, fainting, severe vomiting, or signs of acute illness, seek immediate medical attention by calling 999 or attending A&E.


Creatine is a naturally occurring compound your body produces. You also obtain small amounts from foods such as red meat and fish. Supplementing with creatine increases muscle creatine stores beyond what most diets provide, which is why it consistently shows performance benefits in well-controlled research.[1][3][4][5]

Key takeaway
If you want the best type of creatine to take, the evidence overwhelmingly supports:

  • Creatine monohydrate (powder or capsules) as the default choice[1][2][37][38]
  • 3-5 g daily as a simple, effective dose[1][2][5]
  • A loading phase is optional (helps you feel the benefits sooner, but is not required)[1][5]
  • Paying extra for advanced forms is rarely worthwhile: most have limited or no evidence of superior outcomes and often cost more[35 ‑ 38)]

Overview

Creatine is one of the most widely studied performance and health supplements. It's widely used for strength, power, repeated high-intensity efforts, and to support training adaptations[1][11]. Emerging research also supports potential benefits in healthy ageing, brain energy demands, and certain clinical contexts[1][25 ‑ 31] - but it's still important to keep expectations realistic and match creatine to the type of activity you actually do.

If you're a walker, hiker, or general fitness trainer, creatine can still make sense: it's most useful when your walking life includes hill climbs, interval sessions, gym work, carrying loads, repeated sprints, or anything that feels like short bursts of hard effort rather than steady plodding.[7 ‑ 10]

Basics

What is creatine?

Creatine is a naturally occurring compound derived from amino acids and stored mainly in muscle tissue (it is also present in the brain). In muscle, it exists as free creatine and phosphocreatine, acting as a rapidly available energy buffer[3][4][5]. Creatine in your muscles exists in two usable forms: 'free' creatine (ready to be converted to phosphocreatine) and phosphocreatine (creatine with an extra phosphate attached that your body can quickly use to help 'recharge' energy during short, hard efforts).

You can obtain creatine from food (especially meat and fish), but typical dietary intake is far below the amounts used in most research and supplementation protocols[1][3].

Should I take creatine supplements?

Creatine is most likely to be worth it if you want at least one of the following:

  • More strength/power in the gym[1][11][12]
  • Better performance in repeated bursts (e.g., hills, sprints, hard intervals, team sports)[7 ‑ 10]
  • Support for training volume and adaptation over time[11][12]
  • Help maintain or build muscle as you age[17 ‑ 22]
  • Potential support for certain aspects of cognitive performance under stress[26][27][28]

The idea of helping maintain or build muscle as you age is interesting to me, as more and more recent studies are linking muscle to longevity.

If your only exercise is long, steady, low-intensity walking, creatine may still help indirectly (e.g., by improving recovery from the strength work you add in), but it's not a magic endurance pill. Some studies show little or no benefit for pure endurance performance without a high-intensity component[11].

How creatine works

How does creatine work in the body?

During short, intense efforts, your body rapidly uses ATP. ATP (adenosine triphosphate) is your body's 'immediate energy' molecule - the fuel your cells use to power muscle contractions and other work, especially during short, high-intensity bursts. The phosphocreatine system helps regenerate ATP quickly, helping you maintain force and power output for a little longer and repeat hard efforts with less drop-off[3][4][5][7 ‑ 10].

Infographic showing how creatine supports short uphill surges and repeat hill efforts

Supplementation raises your muscle creatine stores[4][5], which is why creatine reliably benefits high-intensity, repeated efforts more than slow, steady-state exercise.

Absorption and bioavailability of creatine

Creatine monohydrate is well absorbed and effective at increasing muscle creatine[1][4][5][6]. Many new forms claim better absorption, but the key question is: do they outperform monohydrate in outcomes? The best overall evidence suggests: generally no[1][35 ‑ 38].

Proven benefits and uses of creatine

Infographic showing proven creatine benefits for strength, repeated efforts, recovery and cognition

Improving athletic performance

Creatine is best known for improving:

  • Repeated sprint / repeated high-intensity performance[7 ‑ 10]
  • Maximal efforts and high-intensity work capacity[7 ‑ 11]

This is why creatine is so relevant to sports and sessions involving repeated, hard bursts (intervals, hill repeats, circuits, gym work and certain team sports).

Increasing muscle mass and strength

Across many studies and meta-analyses, creatine supplementation combined with resistance training tends to increase lean mass and strength more than resistance training alone[1][11][12].

Women benefit too. Trials in women show that creatine improves strength and training progress[12][13].

Muscle recovery and soreness

Creatine may support recovery from hard eccentric work (think downhill hiking and gym work, or strength sessions that leave you sore). Controlled studies show improved recovery of force after muscle-damaging exercise[14].

Healthy ageing and functional performance

Creatine, combined with resistance training, can be particularly useful in older adults for:

  • Increasing strength and fat-free mass[17 ‑ 22]
  • Improving certain functional performance outcomes (e.g., tasks related to daily living)[18][20][21]

A systematic review/meta-analysis supports additional benefits when creatine is added to resistance training in older adults[19]. This is key, as more studies are linking muscle and longevity.

Bone and falls-related factors

Evidence suggests that creatine, when combined with resistance training, may have potential benefits for bone-related outcomes, though this is an evolving area and results vary by study design[23][24]. In practice, creatine is best viewed as a potential support for a broader healthy-ageing plan that includes resistance training, protein, balance work, and sufficient vitamin D and calcium.

Blood sugar and glucose control

In type 2 diabetes, creatine combined with exercise improved glycaemic control in a randomised controlled trial[25]. This doesn't mean creatine treats diabetes, but it does suggest that creatine may support exercise-mediated metabolic benefits in some populations[25]. Walking can also reduce blood sugar spikes.

Brain function and cognition

Creatine plays an energy role in the brain, too[3]. Human trials and systematic reviews suggest potential benefits in certain cognitive domains, particularly under high brain energy-demand conditions (e.g., stress, sleep deprivation, low dietary creatine intake)[26][27][28].

  • Improved working memory and reasoning were observed in one controlled trial[26].
  • Sleep deprivation studies suggest potential positive effects on mood and tasks that stress executive function[27].
  • A systematic review found possible improvements in short-term memory and reasoning, with mixed results across other domains[28].

Mood and mental health

Research has explored creatine as an adjunct in depression:

  • An RCT in women with major depressive disorder found that adding creatine to SSRI treatment improved clinical response[29].
  • An earlier open-label pilot suggested potential benefit but also highlighted caution in bipolar depression because of the risk of hypomania/mania[30].

This is not a recommendation for self-treatment - it's an area to discuss with a clinician.

Rehabilitation and muscle loss

Creatine has also been studied in rehabilitation contexts. A classic controlled study found that creatine supported rehabilitation from disuse atrophy and affected markers of muscle regeneration[31]. This matters in real life: illness, injury, immobilisation, and starting again are common.

Types of creatine explained

Creatine monohydrate (recommended)

In my view, this is the gold standard for creatine. It's the form used in the bulk of research and consistently improves outcomes in the right contexts[1][2][11][37].

Who it suits: almost everyone.

Buffered creatine (e.g., Kre-Alkalyn)

Claims: Fewer side effects, better retention, and a lower dose required.

Evidence: Controlled studies show no meaningful advantage over monohydrate for muscle creatine, body composition, or training outcomes[35].

Creatine ethyl ester

Claims: Better absorption.

Evidence: Controlled research found it was not superior and appeared less effective at raising muscle creatine levels than monohydrate[36].

Creatine HCl, nitrate, magnesium chelate, liquids, blends

These forms are heavily marketed. Independent outcome research is limited, and broader reviews conclude that no alternative form has convincingly outperformed monohydrate[1][37][38].

Walks4all takeaway
If you tolerate monohydrate, as most people do, there's rarely a compelling reason to upgrade.

Absorption & effectiveness of creatine

Do advanced forms perform better?

Usually, no. Across reviews and comparative evidence:

  • Monohydrate reliably increases muscle creatine[4][5][6]
  • Buffered and ethyl ester forms do not show superiority in real-world outcomes[35][36]
  • Broader analyses of marketed alternatives show a pattern of limited evidence and higher cost[37][38]

Does taking creatine with carbs or protein help?

Comparison showing creatine taken with meals versus with water and daily consistency

It can. Studies show that adding carbohydrate (and/or protein + carbohydrate) can increase creatine retention and muscle creatine accumulation, likely via insulin-mediated mechanisms[15][16]. So, if you already take creatine with a meal or a shake, you're covered.

Dose: How much creatine should you take?

For most adults:

  • 3-5 g daily (or ~0.1 g/kg/day) is effective[1][2][5]

For many people, the simplest plan is: 5 g daily, every day, with no cycling. In creatine terms, as with many other supplements, 'cycling' means taking creatine for a set period (e.g., 4-12 weeks), then stopping for a break (e.g., 2-4 weeks) before starting again - rather than taking a consistent daily dose year-round.

There is emerging evidence that taking a higher dose than this is beneficial, especially for brain function and cognition. I'll keep a watching brief on studies in this area, and I'm testing it myself.

Creatine loading phase

Research on creatine loading

Loading is a strategy to saturate muscle creatine faster[5].

Benefits of creatine loading

You may notice benefits sooner because muscle stores rise quickly[5].

How to load creatine (simple protocol)

A common evidence-based approach:

  • Loading: ~20 g/day split into 4 doses (e.g., 4 × 5 g) for 5-7 days
  • Maintenance: 3-5 g/day afterward[1][5]

Timeline infographic comparing creatine effects with loading versus no loading

If you skip loading, you can still reach saturation, it just takes longer[1][5]. As long as you are in no particular hurry and can wait 3-4 weeks for it to take full effect, that is the way I would recommend, and the way I've always restarted on creatine if I've not taken it for any length of time.

What happens when you start taking creatine?

You may notice:

  • Better ability to repeat hard bursts[7 ‑ 10]
  • Slight scale weight increase due to additional water inside the muscle (often early)[1][2]
  • Better training progression over the weeks[11][12]

Should I take creatine every day?

Yes - daily intake is how you maintain elevated muscle stores[1][5].

What happens when you stop taking creatine?

Muscle creatine stores gradually return towards baseline over a few weeks[11][12]. You don't crash, but performance support fades as stores normalise.

Best time to take creatine

Clock infographic showing different times to take creatine, stressing daily consistency

The evidence-based, practical answer:

  • Timing matters less than consistency. Daily adherence is the key[1][2].
  • Take it whenever you remember: morning, with lunch, post-workout, any time is fine[1][2].
  • If you want to slightly optimise uptake, take it with a meal or a shake containing carbs/protein[15][16].

How to incorporate creatine into your routine

  • Mix into a smoothie or protein shake
  • Add to yoghurt/porridge
  • Use capsules if you dislike the texture

What actually matters when choosing creatine?

Checklist infographic showing what to look for in a creatine supplement and what to avoid

  • Type: Creatine monohydrate[1][37]
  • Dose per serving: Ideally 3 g or 5 g (to make it easy to hit the evidence-based dose)[1][5]
  • Minimal extras: Avoid paying for unnecessary blends[38]
  • Quality and purity: Choose reputable brands; contamination and impurities in supplements are a real concern[39]

Creapure, micronised, flavoured capsules: are these worth it?

  • Creapure can be a quality signal (not more effective, but it can indicate manufacturing standards).
  • Micronised often mixes better; efficacy is still essentially that of monohydrate[37].
  • Flavoured: Convenient, but typically more expensive per gram.
  • Capsules: Convenient but cost more per gram[38].

Safety, side effects, and misconceptions of creatine

Checklist showing who should speak to a clinician before using creatine supplements

Is creatine safe?

In healthy adults, creatine monohydrate is considered safe at recommended doses, supported by extensive research and long-term observations[1][2].

Long-term studies in athletes report no meaningful adverse changes in clinical health markers with prolonged use[34], and kidney-function-focused research in healthy athletes has not shown any impairment[33] .

Common side effects of creatine

Diagram showing creatine drawing water into muscle cells, explaining early scale changes

  • Water retention/scale weight increase early on (not fat gain)[1][2]
  • GI discomfort in some people, especially with large single doses[1][2]

Kidney health: What people worry about versus what the data shows

  • Creatine can increase creatinine (a breakdown product), which can affect some blood tests[2].
  • In healthy athletes, studies show no impairment of renal function with long-term supplementation[33][34].
  • If you have known kidney disease (or are taking medications that affect the kidneys), speak to a clinician first before taking[1][2].

Hydration, cramping, and heat illness

The claim that creatine causes dehydration or cramps doesn't hold up based on the available evidence. A systematic review found no evidence that creatine compromises heat tolerance or body fluid balance at recommended doses[32].

Does creatine cause hair loss?

This idea largely stems from a small study in rugby players, in which the DHT:testosterone ratio changed after creatine supplementation - hair loss itself was not measured[40]. Overall, this is not strong evidence that creatine causes hair loss, but if you're already anxious about androgenetic hair loss, it's reasonable to be cautious and discuss it with a clinician.

Interactions

Most people don't have issues, but be mindful if you:

  • Take medications that affect the kidneys
  • Have medical conditions (kidney disease, bipolar disorder, etc.)
  • Are pregnant/breastfeeding

Clinical caution is especially relevant when considering creatine for non-sport related reasons[1][2][29][30].

Is it worth paying more for better creatine?

For most people: no.

Here's why:

  • A review of creatine forms concludes that no alternative has clearly outperformed monohydrate in efficacy[37].
  • A market analysis found that alternative creatine forms commonly cost more and often lack supporting evidence for their marketing claims[38].
  • Head-to-head research shows that upgraded versions. such as buffered creatine and ethyl ester, don't deliver better outcomes than monohydrate[35][36].

Walks4all takeaway
Spend your money on a quality monohydrate, use it consistently every day, and better training (plus sleep and protein).

Walks4all overall takeaway

Best creatine to take: Creatine monohydrate

Best dose: 3-5 g daily

Loading: Optional

Paying more: Rarely justified

If your goal is to feel stronger on hills, recover better from strength sessions, and maintain muscle as you age, creatine is one of the few supplements that's consistently evidence-backed - when used correctly and paired with training[1][11][17 ‑ 22].

Frequently Asked Questions (FAQs) on the best types of creatine to take

FAQ infographic answering common questions about creatine dose, timing, loading and safety

What is creatine, and what does it do?

Creatine is a naturally occurring compound stored mainly in muscle tissue and also present in the brain. It helps your body rapidly regenerate ATP during short, intense efforts, which can improve repeated high-intensity performance and training output.[1][3][4][5]

What is the best type of creatine to use?

For most people, creatine monohydrate is the best option because it has the strongest evidence for effectiveness, safety, and value. Newer, advanced forms have not consistently shown better real-world outcomes than monohydrate.[1][2][35 ‑ 38]

How much creatine should I take each day?

A simple, evidence-aligned daily dose is 3-5 g (or around 0.1 g/kg/day). Take it consistently to maintain elevated muscle stores.[1][2][5]

Do I need to do a creatine-loading phase?

No - loading is optional. Loading can saturate muscle stores faster, but daily dosing without loading still works; it just takes longer to fully saturate.[1][5]

When is the best time to take creatine?

The best time is whenever you will take it consistently every day. Taking it with a meal or shake can be a helpful routine and may support retention, but timing is generally less important than daily consistency.[1][15][16]

Should I take creatine every day (including rest days)?

Yes. Creatine works by building and maintaining muscle creatine stores, so daily use (training and rest days) is the simplest approach for most people.[1][5]

How long does it take for creatine to take effect?

If you load, stores rise quickly (often within about a week). If you don't load, it typically takes 3-4 weeks of daily dosing to reach full saturation.[1][5]

Does creatine cause weight gain?

Creatine can cause a small increase in body weight, especially early on, mainly from additional water stored in muscle cells; it isn't fat gain. This is more noticeable during a loading phase.[1][2]

Is creatine harmful to your kidneys?

In healthy adults, research does not support kidney damage at recommended doses. If you have kidney disease, abnormal kidney function tests, or take medications that affect kidney function, seek medical advice first.[1][2][33][34]

Does creatine cause hair loss?

Current evidence does not show that creatine causes hair loss. One commonly cited study examined hormone markers (not hair loss itself), and the claim hasn't been confirmed with direct hair-loss outcomes.[2][40]
