1. What is Creatine Monohydrate?
Creatine monohydrate is an organic compound naturally present in the human body, synthesized in the liver, kidneys and pancreas starting from three amino acids: arginine, glycine and methionine .
Where is Creatine Found?
- In the body : ~120 g in the muscles of a 70 kg adult (95% of the total)
- In the diet : red meat (beef, pork), fish (salmon, tuna, cod), poultry
-
Dietary quantities :
- 1 kg of raw red meat: ~5 g of creatine
- 1 kg of salmon: ~4.5 g of creatine
- ⚠️ Cooking destroys 30-50% of creatine
Vegans and vegetarians have muscle creatine levels 10-30% lower compared to omnivores, making integration even more crucial.
Why "Monohydrate"?
The creatine monohydrate it is the form chemically bonded to a water molecule (H₂O). This is:
- The shape more studied (>1000 studies)
- The cheaper and bioavailable
- The safer (approved by EFSA, FDA, ISS)
- 88% pure creatine (the remaining 12% is hydration water)
2. How Creatine Works: The ATP-PCr System
To understand why creatine monohydrate it's so powerful, we have to get into cellular biochemistry.
ATP: The Energy Currency of Muscles
ATP (Adenosine Triphosphate) it is the molecule that provides immediate energy to muscles during contraction. The problem? Muscle ATP reserves last only 2-3 seconds during maximal efforts (sprinting, weightlifting, jumping).
What happens next? The body must quickly regenerate ATP to continue the effort.
The Phosphocreatine (PCr) System
Here's where it comes in creatine monohydrate :
- Creatine + Phosphate (Pi) → Phosphocreatine (PCr) (stored in muscles)
-
During intense effort:
- ATP → ADP + Pi + Energy (ATP is consumed)
- Phosphocreatine (PCr) → Creatine + Pi (releases phosphate)
- ADP + Pi → ATP (immediate regeneration)
Result : Creatine monohydrate increases blood reserves muscle phosphocreatine of 20-40% , allowing you to regenerate ATP faster and longer.
Practical Translation for the Athlete
✅ More repetitions with heavy loads ✅ More sprints at high intensity ✅ More power in jumps, throws, sprints ✅ Faster recovery between series ✅ Higher training volume tolerated.
3. 10 Scientifically Proven Benefits of Creatine Monohydrate
1. Increased Muscle Strength and Power 💪
Key studies :
- +8-14% maximal strength (1RM squat, bench, deadlift) after 4-12 weeks (Kreider et al., 2017)
- +10-20% explosive power (jumps, sprints) (Branch, 2003)
- +5-15% total training volume (multiple sets x reps tolerable)
Mechanism :
- More phosphocreatine → more ATP → more energy for maximal contractions
- Reduction of the accumulation of ADP/AMP (fatigue metabolites)
2. Increased Muscle Mass (Hypertrophy) 🏋️
Key studies :
- +1-2 kg of lean mass in 4-8 weeks (Kreider et al., 2017)
- +2-4 kg total mass in 12 weeks (including glycogen and intracellular water)
Multiple mechanisms :
- Cellular volumization : creatine draws water into muscle cells → "swollen" cell → anabolic signal
- Activation of mTOR pathways : stimulates muscle protein synthesis
- Increased IGF-1 expression : muscle growth factor
- Satellite cell proliferation : formation of new muscle cells (myogenesis)
- Higher training volume : more accumulated hypertrophic stimulus
⚠️ Note : initial 1-2 kg are intracellular water (beneficial!), then true muscle hypertrophy follows.
3. Improved high intensity anaerobic performance ⚡
EFSA approved claim : "Creatine increases physical performance in successive short-term sessions of high-intensity exercise" (dose: 3 g/day).
Documented benefits :
- Repeated sprints : +5-10% speed, reduction of fatigue between sprints
- Weightlifting : +10-20% repetitions to failure
- Team sports (football, basketball, rugby): +5-15% sprints, jumps, changes direction
- CrossFit/HIIT : +10-20% total work in sessions
It does NOT work for : pure aerobic endurance (marathon, long cycling) – in these sports creatine has little or no weight.
4. Accelerated Muscle Recovery 🔄
Key studies :
- -20-40% reduction in muscle damage (CPK, LDH) post-intense training (Cooke et al., 2009)
- -30% reduction in muscle pain (DOMS) at 24-48 hours post-exercise
- Phosphocreatine recovery : +50% faster between sets
Mechanism : creatine reduces oxidative stress and inflammation, accelerates ATP resynthesis.
5. Cognitive Function and Brain Health 🧠
Surprise : the brain uses creatine to produce neuronal energy!
Key studies :
- Improved working memory +10-20% in vegans (Rae et al., 2003)
- Reduction of mental fatigue in prolonged cognitive tasks
- Neuroprotection : study on Parkinson's, Alzheimer's, head trauma (Balestrino & Adriano, 2019)
- Reduction of brain fog in sleep deprivation (McMorris et al., 2007)
Dose for cognitive effect : 5-20 g/day (high doses necessary to overcome the blood-brain barrier).
6. Benefits for the Elderly and Sarcopenia 👴👵
Key studies :
-
Creatine + resistance training in the over 65s:
- +1.5-3 kg of lean mass in 12 weeks
- +20-30% strength (Chilibeck et al., 2017)
- Improved functionality : getting up from a chair, climbing stairs, balance
- Sarcopenia reduction (age-related muscle loss)
Because it works :
- The elderly have reduced muscle creatine reserves (-10-20%)
- Greater sensitivity to integration
- Counteracts muscle catabolism
7. Bone Health (Women Menopause) 🦴
Key studies :
-
Creatine + resistance training in post-menopausal women:
- +3-5% bone mineral density (BMD) in 12 months (Chilibeck et al., 2015)
- Reduction of osteoporosis risk
- Improved strength, balance, reduction of falls
Effective dose : 5 g/day for at least 12 weeks.
8. Metabolic Support (Glycaemia and Insulin) 🍬
Key studies :
- Improved insulin sensitivity in type 2 diabetics (Gualano et al., 2011)
- Post-prandial blood sugar reduction -10-15%
- Increased glucose absorption in muscle cells (GLUT-4)
Mechanism : insulin mimetic creatine for glucose absorption.
9. Cardiovascular Health (Hypertriglyceridemia) ❤️
Emerging studies :
- Reduction of triglycerides -10-20% in sedentary subjects + training (Santos et al., 2021)
- Improved endothelial function
- Homocysteine reduction (cardiovascular inflammatory marker)
Note : effect mainly mediated by increased physical activity made possible by creatine.
10. Support in Neurological Pathologies 🧬
Clinical research (still in experimental phase):
- Parkinson : improvement of motor function (Bender et al., 2006)
- Amyotrophic Lateral Sclerosis (ALS) : slow progression (some conflicting studies)
- Muscular dystrophy : Strength improvement in some forms
- Head trauma : reduction of secondary brain damage
Experimental dose : 10-30 g/day (much higher than the sports dose).
4. Creatine Monohydrate Dosage: Loading vs Maintenance Phase
They exist two main protocols for creatine monohydrate supplementation:
Protocol 1: With Loading Phase (Rapid Method)
Loading Phase (5-7 days) :
- Doses : 0.3 g/kg/day (e.g. 70 kg → 21 g/day)
- Frequency : 4 doses of 5 g distributed throughout the day (breakfast, lunch, snack, dinner)
- Objective : rapidly saturate muscle creatine reserves (+20-40% in 5-7 days)
Maintenance Phase (from day 8 onwards) :
- Doses : 0.03 g/kg/day = 3-5 g/day (e.g. 70 kg → 3 g/day)
- Frequency : 1 single dose per day
- Duration : undefined (no loop necessary)
Pro : ✅ Effects visible quickly (within 1 week)
✅ Complete saturation of muscle reserves
Against : ❌ Possible gastrointestinal disorders (bloating, diarrhea) in the first few days
❌ Greater initial water retention (+2-3 kg)
❌ More expensive
Protocol 2: Without Loading Phase (Gradual Method)
Constant daily dose :
- 3-5 g/day (single dose)
- Duration : indefinite
Objective : gradually saturate muscle reserves over 3-4 weeks.
Pro : ✅ Zero gastrointestinal disorders
✅ Gradual and less evident water retention
✅ Cheaper
✅ More convenient (1 dose per day)
Against : ❌ Effects visible after 3-4 weeks (slower)
Which Protocol Should You Assign?
| Situation | Recommended Protocol |
|---|---|
| Start of competitive season/competition near | With load (speed) |
| Continuous off-season use | Without load (convenience) |
| First time with creatine | Without load (tolerability) |
| Sensitive stomach | Without load |
| You want immediate results | With load |
| Limited budget | Without load |
Conclusion : both protocols work equally well in the long term (after 4 weeks there is no difference). The choice depends on urgency, tolerance and convenience.
5. When and How to Take Creatine Monohydrate
Timing: Pre, Intra or Post-Workout?
The scientific answer : timing is NOT critical for creatine monohydrate. What matters is the daily consistency (take it every day, training or not).
However, there are slight practical advantages :
Post-Training (Best Choice) ⭐
✅ Better muscle uptake : more receptive muscles after training ✅ Synergy with carbohydrates/proteins : post-wo insulin peak favors creatine uptake ✅ Convenience : take with post-workout protein shaker
Recommended dose post-wo : 3-5 g creatine + 30-40 g proteins + 40-60 g carbohydrates
Pre-Training (Valid Alternative)
✅ Immediate availability : phosphocreatine ready during training ✅ It can improve the pump (cell volumization)
Duration : 30-60 minutes before training
Rest days
✅ Hire morning or evening (it makes no difference) ✅ Preferably with meal containing carbohydrates (better absorption)
With what to take creatine?
Better options to maximize absorption :
-
Water + Fast Carbs (maltodextrin, dextrose, fruit juice):
- Insulin peak → creatine absorption +20-30%
- Carbohydrate dose: 30-50 g
-
Post-workout protein shaker :
- Protein + carbohydrates + creatine = perfect combination
-
Plain water :
- It still works (minimal long-term difference)
To be avoided : ❌ Caffeine (high doses >300 mg): some studies suggest interference (conflicting evidence) ❌ Acidic juices (orange, lemon): can degrade creatine into creatinine (ineffective)
How Much Water Should You Drink?
Creatine monohydrate increases intracellular water retention (beneficial!), but you need to drink more:
- Minimum 2.5-3 liters of water/day
- +500 ml for every 5 g of creatine hired
- Sign of good hydration: light yellow urine
6. Creatine Monohydrate vs Other Forms of Creatine
There are more than that on the market 20 different shapes of creatine. Here's the scientific truth:
Creatine Monohydrate (The Queen) 👑
Pro : ✅ More studied : >1000 published studies ✅ More effective : 20-40% increase in muscle PCr ✅ Cheaper : €0.10-€0.30/dose ✅ Safer : EFSA, FDA, ISS approved ✅ Bioavailability : ~99% absorption (if pure)
Against : ❌ Moderate solubility in cold water (resolves with warm water or micronization)
❌ Possible GI disorders with high load (resolvable with gradual protocol)
Creatine HCl (Hydrochlorate)
Claim : "41 times more soluble, lower dose (1-2 g), zero swelling"
Scientific truth :
- ⚠️ Zero studies demonstrating superiority on monohydrate
- Greater solubility ≠ greater efficacy
- Dose is 1-2 g insufficient to saturate the muscles
- Much more expensive (€1-2/dose vs €0.20 monohydrate)
Conclusion : hype, no real benefit.
Creatine Ethyl Ester
Claim : "Greater bioavailability, no retention"
Scientific truth :
- ❌ Less effective of monohydrate (study Spillane et al., 2009)
- It breaks down into creatinine (ineffective) in the stomach
- demonstrated advantage
Conclusion : total flop.
Alkaline Creatine (Kre-Alkalyn)
Claim : "high pH, zero creatinine degradation, no load"
Scientific truth :
- ⚠️ Zero studies demonstrating superiority (study Jagim et al., 2012: same as monohydrate)
- Creatinine degradation is minimal even with monohydrate
- Much more expensive
Conclusion : same effect, triple the price.
Micronized Creatine
What is it : creatine monohydrate with reduced particles (200 mesh)
Real benefits : ✅ Better solubility in cold water ✅ Reduction of GI disorders (faster absorption) ✅ Same effectiveness of the classical monohydrate
Conclusion : excellent choice if classic monohydrate causes solubility/stomach problems. Small justified surcharge.
Creapure® (reference standard)
What is it : creatine monohydrate purity 99.99% , produced in Germany (AlzChem)
Certifications : ✅ GMP, ISO, HACCP
✅ Sport Informed (anti-doping)
✅ Vegan, Kosher, Halal
✅ Zero contaminants (DHT, DCD, creatinine)
Conclusion : the global benchmark for creatine monohydrate. If you want the best, choose Creapure®.
Final Verdict
95% of athletes should use creatine monohydrate (preferably Creapure® or micronized). Other forms are marketing campaigns without superior scientific evidence.
7. Myths to dispel about Creatine Monohydrate
Myth 1: "Creatine Damages the Kidneys" ❌
Scientific truth :
- ✅ Zero kidney damage in healthy subjects (>30 years of study)
- ✅ Study Kim et al. (2011): 5 g/day for 5 years → normal renal function
- ✅ Creatinine increases (creatine metabolite), but it is an unreliable marker in those who supplement creatine
- ✅ Use creatinine clearance or cystatin C to evaluate true renal function
Who needs to pay attention : only those who have pre-existing renal disease (consult nephrologist).
Myth 2: "Creatine Causes Swelling and Retention of Subcutaneous Water" ❌
Scientific truth :
- ✅ Intracellular water retention (inside the muscle cells) → fuller, more voluminous muscles
- ❌ NOT subcutaneous retention (the one that makes you look "bloated")
- ✅ Initially +1-3 kg (water + glycogen + creatine), then stabilizing
Conclusion : Creatine improves muscle appearance, not worsens it.
Myth 3: "You need to cycle Creatine (On/Off)" ❌
Scientific truth :
- ✅ No need for cycles (Kreider et al., 2017)
- ✅ Creatine monohydrate does not downregulate receptors nor does it cause addiction
- ✅ Continuous use is safe and more effective
When to suspend :
- Only if you want to test the natural response (curiosity)
- After discontinuation, muscle creatine levels return to baseline 4-6 weeks
Myth 4: "Creatine Causes Muscle Cramps" ❌
Scientific truth :
- ✅ Creatine REDUCES cramps (if well hydrated) (Lopez et al., 2009)
- ✅ Cramps were associated with dehydration (resolved by drinking more)
Solution : drink 2.5-3 L water/day.
Myth 5: "Creatine is a Steroid/Dopant" ❌
Scientific truth :
- ✅ Creatine is natural substance (food, body produces it)
- ✅ Legal in all sports (NOT on the WADA list)
- ❌ It is NOT anabolic (does not affect testosterone/hormones)
Myth 6: "Creatine Doesn't Work for Everyone" ⚠️ Partially True
Scientific truth :
- 20-30% population = "non-responder" (PCr increase <10%)
- Why? Already have high muscle creatine levels (genetics, meat-rich diet)
- Vegans/vegetarians : 100% responder (starts from low levels)
How to understand if you are a responder?
- Try 4-8 weeks: if +strength/mass/performance → responder
- Otherwise: you are already naturally saturated (lucky!)
8. Side Effects and Safety of Creatine Monohydrate
Real Side Effects (Rare and Mild)

Gastrointestinal disorders (5-10% users):
- Bloating, nausea, diarrhea
- Cause : high doses (>10 g) on an empty stomach
- Solution : divide the dose, take with food, use micronized
-
Weight gain (+1-3 kg first days):
- Intracellular water + glycogen
- It's not fat , is beneficial for performance
-
