If you've set your SMART goals and you're showing up consistently, the next question is simple: are you giving your body the right tools to actually get there?
Creatine is one of the most researched supplements in sports nutrition history. It's not a trend. It's not a steroid. And it's not just for bodybuilders. Yet despite decades of evidence, it remains one of the most misunderstood compounds in the gym bag.
This is the straight-shooting, evidence-led guide to creatine — what it does, what's genuinely new in the research, and how to use it properly.
What Creatine Actually is
Creatine is a naturally occurring compound found primarily in meat and seafood, and also produced in small amounts by your liver and kidneys. Around 95% of your body's creatine is stored in skeletal muscle as creatine and phosphocreatine.
Phosphocreatine acts as rapid backup fuel for high-intensity efforts — it helps regenerate ATP, the immediate energy currency your muscles (and brain) rely on. When you're pushing through a heavy set, a sprint, or a repeat effort, your phosphocreatine stores are what keep you going in those critical seconds.
Supplementing with creatine increases those stores. More stores means more fuel available when it counts.
The Proven Benefits (The Ones That Hold Up)
Increased Strength and Power Output
Creatine reliably improves performance in high-intensity, short-duration work — heavy sets, sprints, and repeated efforts. In practice, this often means:
-
More reps completed at a given load
-
Better repeat sprint ability
-
Higher peak power output
Over weeks and months, that extra training volume compounds into greater strength and performance gains. [1]
Increased Lean Mass
Creatine consistently increases lean body mass, particularly when combined with resistance training. Two things are happening:
-
Training effect: You can do more quality work, recover better, and progress faster.
-
Intracellular water: Creatine draws water into muscle cells. This is not "fake muscle" — it's a real physiological adaptation — but it does explain why the scale can tick up early.
Don't let that put you off. The lean mass gains that follow are real. [1][2]
Improved Training Capacity and Recovery
Creatine isn't a stimulant. You won't feel it like caffeine. The benefit is that it supports repeated high-intensity output and reduces the performance drop-off across sets.
Think of it as a "do more quality work" supplement. And in the long run, that's exactly what drives results.
What's New: Brain, Cognition, and High-Demand States
Creatine research in cognition is one of the most active areas right now — and it's also where people get sloppy and overclaim. Here's the accurate version.
Cognitive Performance: Promising in Specific Contexts
A 2024 systematic review and meta-analysis reported small but meaningful beneficial effects on specific cognitive domains — particularly memory — while noting that evidence quality varies and not all domains improve consistently. [3]
At the same time, EFSA (the European Food Safety Authority) reviewed the evidence and concluded that a cause-and-effect relationship has not yet been established for a broad cognitive function health claim across the general population. [4]
What this means honestly: Creatine has potential cognitive benefits, especially under high cognitive demand or stress. It is not a guaranteed brain supplement for every healthy person in every situation. The research is encouraging — not conclusive.
Creatine and Sleep Deprivation / High-Demand States
One of the more interesting emerging discussions — including content from The Diary of a CEO — centres on creatine's potential role when the brain is under stress, including sleep deprivation. The mechanism proposed is brain energy buffering: creatine may help maintain ATP availability in the brain during periods of high demand or reduced recovery.
The Diary of a CEO has explored this directly, including a recent episode asking: Can creatine offset the effects of sleep deprivation? [5] And a longer conversation with Dr Rhonda Patrick covering creatine's role in longevity, brain health, and performance. [6]
Important framing: Podcast content is not primary evidence. It's valuable for explaining why researchers are interested — the mechanisms, the hypotheses, the early findings. Claims still need to be anchored to peer-reviewed research, which is why the reviews above matter.
Common Misconceptions (And the Actual Truth)
"Creatine is a steroid"
No. Creatine is not anabolic-androgenic. It's a naturally occurring compound involved in cellular energy metabolism. It's widely studied, permitted in all sport, and has nothing to do with hormones.
"Creatine damages your kidneys"
In healthy individuals, creatine supplementation at standard doses has not been shown to damage kidney function in the evidence base used across sports nutrition practice. [2]
One nuance worth knowing: creatine can increase serum creatinine (a breakdown marker) without any actual kidney damage — which can confuse blood test interpretation. If you're supplementing and getting bloodwork done, let your GP know.
Anyone with pre-existing kidney disease should speak with a clinician before supplementing.
"Creatine causes dehydration and cramps"
This fear persists, but it's not supported as a general rule. Creatine increases intracellular water in muscle — it doesn't pull water away from the rest of your body. That said, if you're training hard in the heat, manage your hydration regardless. That's just good practice.
"It's only for bodybuilders"
Creatine can benefit:
-
Strength and power athletes
-
Team sport athletes (repeat sprint capacity)
-
Recreational lifters who want better training output
-
Older adults working to preserve strength and function
-
Plant-based athletes, who tend to have lower baseline creatine stores and may respond particularly well
Safety: What We Can Confidently Say
For most healthy adults, creatine monohydrate is considered one of the most well-studied supplements available, with a strong safety profile at standard doses.
What to expect:
-
A weight increase of ~1–2 kg in the early phase is common (primarily intramuscular water)
-
Occasional GI discomfort in some people, often dose-related — taking it with food usually helps
Who should seek medical advice first:
-
People with known kidney disease or reduced renal function
-
People on medications that affect kidney function
-
Pregnant or breastfeeding individuals (not because it's proven harmful — evidence is simply limited, and caution is appropriate)
Who Should Take Creatine
Consider creatine if you:
-
Do resistance training and want measurable performance progression
-
Play field or court sports involving repeated hard efforts
-
Are an older adult focused on maintaining strength and function (with GP or allied health guidance)
-
Eat a plant-based or low-meat diet and want to optimise your creatine stores
You can probably skip it if:
-
You're not training consistently yet — get the basics right first
-
You're unwilling to accept small early scale-weight changes
-
You have a medical reason to avoid it — speak with your clinician
How to Take It (Simple, Effective, No Drama)
-
Form: Creatine monohydrate — it's the benchmark, it's the most studied, and it works
-
Dose: 3–5 g daily, every day
-
Timing: Not critical — consistency is what matters
-
Loading phase: Optional. 20 g/day for 5–7 days saturates stores faster, but it's not necessary and is more likely to cause GI discomfort
