Creatine
Creatine Monohydrate
The most researched supplement for strength, power, and cognitive function under stress.
Creatine monohydrate is the most extensively studied sports supplement with over 1,000 peer-reviewed publications. It increases phosphocreatine stores in muscles, enabling faster ATP regeneration during high-intensity activities.
Mechanisms of Action
ATP Production
Increases cellular energy availability by replenishing ATP stores faster
Brain Energy
Supports cognitive function under stress or sleep deprivation
Cellular Recovery
Accelerates muscle repair and reduces exercise-induced damage
Recommended Dose
5g daily
Loading: Optional: 20g/day (4x5g) for 5-7 days to saturate faster
Optimal Timing
- Any time
- Post-workout may have slight advantage
Can be taken without food
Best Form
Monohydrate powder
Alternatives: Capsules, Micronized monohydrate
Monohydrate is the most studied form. Other forms (HCL, ethyl ester) offer no proven advantages.
Duration
Minimum: 4 weeks
Optimal: 8 weeks
Cycling: Not required
Note: Consistency matters more than timing. Take daily, even on rest days.

Increased Strength
Noticeable improvement in max lifts and power output
Muscle Fullness
Muscles appear fuller due to increased water retention in muscle cells
Water Retention
Temporary weight gain (1-3 lbs) from intracellular water
Better Workout Capacity
Ability to do more reps or sets before fatigue
Insufficient data; consult healthcare provider
Generally safe for athletes 18+; younger should consult doctor
Who Should NOT Take This

Top studies from 40+ peer-reviewed papers
de Guingand DL et al. • Nutrients (2020)
“However, all future studies of creatine supplementation in females should consider surveillance and comprehensive reporting of adverse outcomes to better inform participants and health professionals involved in future trials.”
Key Findings:
- Six hundred and fifty-six studies were identified where creatine supplementation was the primary intervention; fifty-eight were female only studies (9%).
- No statistically significant difference was reported in measures of renal or hepatic function.
- In conclusion, mortality and serious adverse events are not associated with CrM supplementation in females.
- Nor does the use of creatine supplementation increase the risk of total adverse outcomes, weight gain or renal and hepatic complications in females.
Kreider RB et al. • Journal of the International Society of Sports Nutrition (2017)
“Creatine monohydrate is the most effective ergogenic nutritional supplement currently available to athletes for increasing high-intensity exercise capacity and lean body mass.”
Key Findings:
- Increases strength by 5-15%
- Enhances muscle mass gains
- Improves high-intensity exercise performance
Wang Z et al. • Nutrients (2024)
“In conclusions, creatine supplementation with resistance training enhances upper- and lower-body muscle strength in adults aged < 50, with greater benefits likely to be seen in males than females.”
Key Findings:
- In comparison with a placebo, creatine supplementation combined with resistance training significantly increased upper-body (WMD = 4.43 kg, p < 0.001) and lower-body strength (WMD = 11.35 kg, p < 0.001).
- Subgroup analyses showed a trend for greater upper-body strength improvements for males on creatine compared with females on creatine (p = 0.067, Q = 3.366).
- Additionally, males who consumed creatine combined with resistance training significantly increased both upper- and lower-body strength, whereas females showed no significant gains.
- There was a trend indicating greater lower-body strength gains from high-dose creatine compared with lower doses (p = 0.068, Q = 3.341).
Pashayee-Khamene F et al. • Journal of the International Society of Sports Nutrition (2024)
“Creatine supplementation has a small effect on body mass and estimates of fat-free mass and body fat percentage.”
Key Findings:
- Creatine supplementation increased body mass (WMD: 0.86 kg; 95% CI: 0.76 to 0.96, I2 = 0%) and fat-free mass (WMD: 0.82 kg; 95% CI: 0.57 to 1.06, I2 = 0%) while reducing body fat percentage (WMD: -0.28 %; 95% CI: -0.47 to -0.09; I2 = 0%).
- Creatine supplementation has a small effect on body mass and estimates of fat-free mass and body fat percentage.
- These findings were more robust when combined with resistance training.
Prokopidis K et al. • Nutrition Reviews (2023)
“Creatine supplementation improved measures of memory compared with placebo, with significant benefits in older adults.”
Key Findings:
- Significant improvement in memory (SMD = 0.29)
- Greater benefits in older adults (66-76 years)
- Supports brain health across lifespan
