Creatine Monohydrate
The most evidence-backed supplement for strength, muscle, and emerging brain health benefits.
Creatine monohydrate is the most studied sports supplement in existence, with over 500 peer-reviewed studies confirming its safety and efficacy. It is a naturally occurring compound found in muscle tissue that serves as a rapid energy source for high-intensity activity. Supplementation increases intramuscular phosphocreatine stores by 20-40%, improving strength, power output, and training capacity. Emerging research also shows significant benefits for brain health and aging.
Evidence-Based Benefits
Strength & Power
Increases phosphocreatine stores, providing more rapid energy for heavy lifts and explosive movements. Meta-analyses show 5-10% strength gains.
Muscle Growth
Enhances training capacity (more reps, more volume) and may directly stimulate muscle cell signaling pathways like mTOR.
Recovery
Reduces muscle damage markers and inflammation after intense exercise, potentially speeding recovery between sessions.
Brain Health
The brain is highly energy-dependent. Creatine supplementation improves cognitive performance, especially under stress, sleep deprivation, or aging.
Sarcopenia Prevention
Robust evidence in older adults showing creatine combined with resistance training preserves muscle mass and strength better than training alone.
Bone Health
Emerging evidence suggests creatine combined with resistance training may improve bone mineral density in postmenopausal women.
Dosing Guide
Loading phase (20g/day for 5-7 days) saturates stores faster but is not necessary. 3-5g daily will reach saturation in 3-4 weeks. No need to cycle. Creatine monohydrate is the only form with robust evidence — ignore marketing for "advanced" forms.
Forms & Comparison
Creatine Monohydrate
The gold standard. Cheapest, most studied, and most effective form. All other forms are compared against it.
Micronized Creatine Monohydrate
Same compound, smaller particles. May dissolve better in water. No difference in efficacy.
Creatine HCl
Marketed as better absorbed, but no evidence of superior efficacy over monohydrate. More expensive for no proven benefit.
Buffered Creatine (Kre-Alkalyn)
Marketed to reduce bloating. Research shows no advantage over monohydrate.
Cautions & Interactions
- May cause 2-4 lbs of water weight gain (intracellular, not bloating) in the first 1-2 weeks.
- Adequate hydration is important — drink at least 8 glasses of water per day.
- Safe for kidneys in healthy individuals — over 500 studies confirm no kidney damage.
- Not recommended with severe pre-existing kidney disease without medical supervision.
- Does not cause hair loss — the one study suggesting this (via DHT) had significant methodological issues.
Frequently Asked Questions
Does creatine cause kidney damage?
No. This myth persists despite 500+ studies showing no kidney damage in healthy individuals. Creatine does elevate creatinine (a kidney marker) because creatinine is a breakdown product of creatine — not because the kidneys are being damaged. If you have pre-existing kidney disease, consult your doctor.
Do I need to load creatine?
No. Loading (20g/day for 5-7 days) reaches saturation faster but causes more GI discomfort and water retention. Simply taking 3-5g daily reaches the same saturation level in 3-4 weeks.
Should I cycle creatine?
No evidence supports cycling. Creatine has no downregulation effects. Consistent daily use maintains muscle saturation. Stopping just depletes your stores over 4-6 weeks.
Does creatine cause hair loss?
This concern comes from a single 2009 study that found creatine increased DHT in rugby players. The study has never been replicated, and subsequent research has not confirmed a link between creatine and hair loss.
