Creatine Monohydrate

Also known as: creatine, Creapure

Grade A — Strong Evidenceamino acidperformance
3–5 gAny time, daily consistency matters most. Post-workout with carbs + protein for best uptake.

Creatine monohydrate is arguably the most researched sports supplement in history, with over 500 peer-reviewed studies supporting its safety and efficacy. Beyond its well-established benefits for strength and power output, emerging research shows cognitive benefits — particularly under conditions of sleep deprivation, stress, or aging. Your body produces ~1g/day and you get ~1g from a typical omnivorous diet, but supplementing with 3-5g daily saturates muscle and brain stores.

TL;DR: One of the most researched supplements in history. Strong evidence for strength, power, and emerging evidence for brain function.

Forms Comparison

Creatine Monohydrate

✓ High Absorption

The original and most researched form. Decades of safety data. No other form has proven superior.

everything — this is the gold standard

Micronized Creatine Monohydrate

✓ High Absorption

Same as monohydrate but with smaller particles for better mixability. No absorption difference.

better mixability in water

Creatine HCl

✓ High Absorption

Hydrochloride salt form. More soluble in water but NOT proven more effective than monohydrate.

those with bloating from monohydrate

Buffered Creatine (Kre-Alkalyn)

~ Moderate Absorption

pH-buffered form marketed as superior. Studies show no advantage over monohydrate.

marketing hype — save your money

Interaction Warnings

DiureticsModerate

Creatine increases intramuscular water; combined with diuretics may cause dehydration

NSAIDsLow

Both put kidney load; acceptable if kidneys healthy

CaffeineLow

High-dose caffeine (600mg) may blunt loading effects; normal coffee intake fine

⚠️ Important Notes

  • Stay well hydrated
  • Safe at recommended doses — decades of research
  • Mildly increases serum creatinine (not kidney damage in healthy people)
