Creatine is the most studied supplement in sports nutrition history. Over 500 peer-reviewed studies confirm its safety and efficacy for improving strength, power output, and lean muscle mass. If you're not taking it, you're leaving performance on the table.
What Is Creatine?
Creatine is a naturally occurring compound found in muscle cells. It helps produce ATP (adenosine triphosphate) — the primary energy currency for high-intensity exercise. Supplementing creatine increases your muscle phosphocreatine stores, allowing you to train harder before fatiguing.
The Proven Benefits
- Increased strength — meta-analyses show 5–10% improvement in 1RM strength
- More reps — enables 1–2 additional reps at submaximal loads
- Greater muscle mass — through improved training volume and cell volumization
- Faster recovery — reduces muscle cell damage and inflammation
- Cognitive benefits — emerging evidence for brain health and memory
Which Form of Creatine?
Creatine Monohydrate (The Winner)
Creatine monohydrate is the most studied, most proven, and most affordable form. Every other form (HCL, buffered, ethyl ester) costs more and shows no meaningful benefit over monohydrate in research.
Don't let marketing fool you. Creatine monohydrate is the gold standard.

How to Take Creatine
Loading Phase (Optional)
Take 20g per day (divided into 4 doses of 5g) for 5–7 days. This saturates muscle stores faster.
Maintenance Phase
Take 3–5g per day. This is all you need to maintain elevated creatine levels once saturated.
Loading is not required. You can skip straight to 5g/day — it just takes 3–4 weeks to reach full saturation instead of 1 week.
When to Take It
Timing doesn't matter much. Take it whenever it's convenient — with a meal is fine. Consistency is what matters.
Common Creatine Questions
Does it cause water retention? Creatine draws water into muscle cells (intracellular), which increases muscle fullness and size. This is a good thing. It does not cause bloating or subcutaneous water retention.
Is it safe long-term? Yes. Studies spanning up to 5 years show no negative effects on kidney or liver function in healthy individuals.
Do I need to cycle off it? No. Cycling creatine is not supported by research. You can take it continuously.
Will it work if I'm a vegetarian? Potentially more so. Vegetarians have lower baseline muscle creatine levels and tend to respond more dramatically to supplementation.
Who Shouldn't Take Creatine?
People with pre-existing kidney disease should consult a physician before supplementing. Everyone else — it's one of the safest supplements available.
The Bottom Line
Creatine monohydrate is the single most cost-effective supplement for athletic performance. It works, it's safe, it's cheap, and it's been proven in hundreds of studies. Take 5g every day, don't overthink it.

Frequently asked
Questions people ask about this
Does creatine cause water retention?
Creatine draws water into muscle cells (intracellular), which increases muscle fullness and size. This is beneficial — it does not cause bloating or subcutaneous water retention that affects how you look.
Is creatine safe to take long-term?
Yes. Studies spanning up to 5 years show no adverse effects on kidney or liver function in healthy individuals. People with pre-existing kidney disease should consult a physician before supplementing.
Do I need to cycle off creatine?
No. Cycling creatine is not supported by research — you can take 3–5 g per day continuously without your body downregulating its own creatine production in any meaningful way.
Does creatine work for vegetarians?
Vegetarians often respond more dramatically to creatine supplementation because they have lower baseline muscle creatine stores. Dietary creatine comes primarily from red meat and fish, so plant-based eaters have more room to saturate.
When should I take creatine for best results?
Timing doesn't meaningfully matter — morning, pre-workout, post-workout, with food, or without. Consistency is what drives results. Take it at whatever time you'll reliably remember every day.
Which form of creatine is best?
Creatine monohydrate. Every other form (HCl, buffered, ethyl ester, kre-alkalyn) costs significantly more and shows no meaningful performance advantage over monohydrate in head-to-head research. Micronized monohydrate is the gold standard.
