Creatine
The most heavily researched, scientifically validated supplement on the planet. If you train, you should be taking it.
The Full Breakdown
What Actually Is It?
Creatine is a naturally occurring compound that your body produces from three amino acids — arginine, glycine and methionine. You also get small amounts from red meat and fish. About 95% of the creatine in your body is stored in skeletal muscle. Here's why it matters: when you lift, sprint, or jump, your body relies on ATP for immediate energy. Problem is, your muscle ATP stores only last about 1–3 seconds of all-out effort. Creatine binds with phosphate to form phosphocreatine, which acts as a rapid reserve to regenerate ATP during those first 10 seconds of explosive work. More phosphocreatine means more reps, more power, more force before fatigue hits. When you supplement, you're saturating your muscle stores beyond what diet alone can achieve. The average person stores about 120–140mmol/kg. Supplementation pushes that to 160–200mmol/kg, and that extra capacity translates directly to performance. The International Society of Sports Nutrition position stand confirms this across hundreds of studies. But here's what most people miss — creatine isn't just a muscle thing. Your brain uses it for energy metabolism too, and research is increasingly showing benefits for cognitive function, memory and mental fatigue resistance. It's one of the most exciting areas of current research. At the end of the day, creatine isn't exotic. It's something your body already makes and uses every day. Supplementation just gives you more of what you already have — and the difference is backed by more evidence than virtually anything else in sports nutrition.
Which Type Do I Buy?
Four popular forms. Here's how they actually compare.
Creatine Monohydrate
Over 500 studies support its effectiveness for strength, power, muscle mass and exercise performance. The most cost-effective option with the deepest evidence base in all of sports nutrition.
- Effectiveness★★★★★
- Research Volume500+ Studies
- Absorption~99%
- Cost Per Serve~$0.05
- Water RetentionMild (Intracellular)
Creapure®
Premium-grade monohydrate manufactured by AlzChem in Germany. Same creatine, higher purity — consistently 99.99% with stricter controls on impurities like creatinine and dicyandiamide. The go-to for athletes who want the cleanest sourcing available.
- Effectiveness★★★★★
- Research Volume200+ Studies
- Purity99.99%
- Cost Per Serve~$0.10
- Water RetentionMild (Intracellular)
Creatine HCL
Bonded with hydrochloric acid for significantly higher water solubility. Popular with people who prefer a smaller serving size (typically 1–2g) and want a powder that mixes easily with no residue. Less direct performance research than monohydrate, but growing in popularity.
- Effectiveness★★★★☆
- Research VolumeEmerging
- SolubilityVery High
- Serving Size1–2g
- Cost Per Serve~$0.25–$0.40
Buffered (Kre-Alkalyn)
Processed to a higher pH to reduce conversion to creatinine in the stomach. Marketed as requiring no loading phase and causing less water retention. A solid alternative for those who want a different approach, with a loyal following among lifters.
- Effectiveness★★★★☆
- Research VolumeLimited
- pH LevelAlkaline (>7)
- Serving Size1–2g
- Cost Per Serve~$0.30–$0.50
Monohydrate vs Creapure®
The only comparison that actually matters.
Purity
Standard monohydrate: 99.9% pure. Creapure: 99.99%, with significantly lower impurity levels. For most people the difference is negligible. For competitive athletes supplementing long-term, the extra margin is worth considering.
Manufacturing
Creapure is produced in a single facility in Trostberg, Germany under pharmaceutical-grade conditions. Standard monohydrate comes from multiple manufacturers worldwide with varying quality controls. The supply chain consistency is genuinely unmatched.
Value
Standard monohydrate is dirt cheap — around $0.05 per serve. Creapure costs roughly double. But even at double, it's still one of the cheapest effective supplements you can buy. If budget isn't a factor, Creapure is the no-brainer for peace of mind.
Performance
The honest truth: in head-to-head studies, there is no meaningful performance difference. They both saturate muscle stores to the same degree. The difference is quality assurance, not results.
Testing
Creapure is batch-certified free from banned substances. While reputable monohydrate brands also test, the Creapure manufacturing process inherently reduces contamination risk. For drug-tested athletes, this matters.
Our Verdict
Both are excellent. Want the cheapest option that works? Standard monohydrate. Want the cleanest manufacturing, highest purity and most transparent sourcing? Go Creapure. You can't go wrong with either.
Increased Strength
Meta-analyses consistently show 5–10% improvements in maximal strength in trained individuals. That's the difference between a plateau and a new PR. Burke et al. (2008) demonstrated this across multiple strength measures.
More Power Output
Sprint speed, jump height, throw velocity, the first few reps of a heavy set — all improve. This is the most consistently demonstrated effect in the entire creatine literature.
Greater Muscle Mass
Through increased training volume capacity, cell volumisation (water drawn into muscle cells), and potentially enhanced satellite cell activity, creatine reliably supports lean mass gains over time.
Improved Recovery
Research shows reduced muscle damage markers, decreased inflammation, and faster recovery between sets and sessions. More quality reps per session, less downtime between sessions.
Brain Benefits
Emerging evidence shows improved cognitive performance under sleep deprivation, mental fatigue and stress. Rae et al. (2003) first demonstrated this, and the research has only grown since.
Safe Long-Term
Studies extending 5+ years show no adverse effects on kidney or liver function in healthy individuals. Shao et al. (2006) and subsequent long-term trials confirm this repeatedly.
How To Use It
Two proven approaches. Both work. Pick one.
Loading Phase
The fastest way to saturate your stores. You'll reach full saturation in 5–7 days instead of 3–4 weeks. Some people experience mild stomach discomfort during loading, but it's generally well tolerated.
Best for: People who want results fast and don't mind multiple serves for the first week.
No Loading
The simpler approach. Skip loading entirely and take a consistent daily dose. You'll reach full saturation in roughly 3–4 weeks, but you avoid any potential GI discomfort from large single doses.
Best for: Most people. It's simpler, there's no downside, and the end result is identical.
What To Expect
A realistic timeline when you start supplementing.
Stores Begin Rising
If loading, you're already near saturation. If not, stores are climbing gradually. You may notice 0.5–1kg weight increase — this is water drawn into muscle cells, not fat. It's a sign it's working.
Performance Shifts
An extra rep or two on working sets, slightly more explosive power, feeling like you can push harder before fatigue sets in. The gains are subtle but consistent.
Full Saturation
Even without loading, your stores are maximised. Performance benefits are fully in play. Measurable improvements in training volume and more reliable progressive overload.
Compounding Results
The strength and muscle gains from training harder, recovering faster, and doing more quality volume start compounding. Creatine isn't magic — it enables you to do more work, and that work drives adaptation.
Myths Busted
The most common misconceptions, killed with evidence.
The Bottom Line
Creatine monohydrate is the single most effective, affordable, and safe supplement you can buy. If you train with any real intent, you're leaving results on the table without it. Pick standard monohydrate for maximum value, or Creapure for the cleanest sourcing. Take 5g daily. That's it.
