How It Works

Creatine phosphate donates phosphate groups to ADP → ATP in the phosphocreatine energy system. Increases intramuscular phosphocreatine by 20-40%. Also increases cell hydration (volumization), which may stimulate protein synthesis.

Dosage & Timing

Dosage Guide

Daily Dose3-5 g

TimingDaily (loading phase optional: 20g/day × 5-7 days, then 3-5g maintenance)

BioavailabilityMonohydrate form: near 100% absorption. Micronized versions dissolve better but same bioavailability. Take with carbs/protein to increase uptake ~60% via insulin-mediated transport.

Optimal Timing

Take with carbs or protein to increase muscle uptake ~60% via insulin. Post-workout timing slightly better than pre. Consistency matters more than timing — 5g every day.

Blood Markers to Monitor

Creatinine (expected to rise — not kidney damage)
eGFR (may show "false" decrease on creatine)
Cystatin C (more accurate kidney marker while on creatine)

Cycling & Duration

No cycling required — safe for continuous daily use.

Best Forms (Ranked)

Creatine Monohydrate — ★★★★★

Gold standard. Most researched. Cheapest.

Creatine HCl — ★★★☆☆

More soluble, less bloating claimed. Less research. More expensive.

Creatine Ethyl Ester — ★☆☆☆☆

Less effective than monohydrate. Breaks down to creatinine faster.

Buffered Creatine (Kre-Alkalyn) — ★★★☆☆

Claims better stability. No clear advantage over monohydrate in studies.

Evidence-Based Benefits

5-15% strength increase
10-20% power output improvement
2-5 lbs lean mass gain
Cognitive benefits in sleep-deprived/sleep-deprived states
Neuroprotective potential

Side Effects & Safety

Water retention (1-3kg)
GI discomfort (if dosed too high at once)
No kidney damage in healthy individuals (extensively studied)

✅ Good For

Strength athletes
Sprint/power athletes
Vegetarians/vegans (lower baseline stores)
Older adults (sarcopenia prevention)
Anyone doing high-intensity training

⚠️ Skip If

Those with pre-existing kidney disease (consult doctor)
Not necessary for endurance-only athletes
