Our Top 5 Picks

Best Creatine Supplements, Ranked

All picks use Creapure® or independently NSF/Informed Sport certified monohydrate unless noted.

RANK 01 / 05
Best Overall NSF Certified Monohydrate
★★★★★ 5.0 / 5.0 — Editor's Pick
Thorne Creatine
Type: Creatine Monohydrate Dose: 5 g / serving Price/serving: ~$0.50 Servings: 90

Thorne is the gold standard for quality control in the supplement industry. Their creatine is NSF Certified for Sport — the same certification used by MLB, NFL, and Olympic athletes. It mixes clean, has zero filler, and consistently passes independent heavy metal testing. If you want one creatine you never have to question, this is it.

Pros
  • NSF Certified for Sport
  • No additives or fillers
  • Trusted by elite athletes
  • Excellent mixability
Cons
  • Slightly pricier than bulk
  • Unflavored only

Informed Sport Monohydrate
★★★★★ 4.8 / 5.0
Klean Athlete Klean Creatine
Type: Creatine Monohydrate Dose: 5 g / serving Price/serving: ~$0.55 Servings: 60

Klean Athlete uses Creapure® — the globally recognized pharmaceutical-grade creatine monohydrate manufactured in Germany by AlzChem. Informed Sport certified, meaning every batch is tested for 250+ banned substances. A top choice for competitive athletes and anyone prioritizing purity.

Pros
  • Creapure® certified source
  • Informed Sport batch-tested
  • Ultra-pure, no taste
Cons
  • Fewer servings per tub
  • Premium price point

RANK 03 / 05
Budget Pick Micronized Monohydrate
★★★★☆ 4.5 / 5.0
Optimum Nutrition Micronized Creatine
Type: Micronized Monohydrate Dose: 5 g / serving Price/serving: ~$0.17 Servings: 120–240

The best value-per-gram option that still clears quality bar. ON's micronized creatine dissolves more easily than non-micronized and is manufactured in GMP-certified facilities. Widely available, consistently pure on independent testing, and at ~$0.17/serving it has no serious competition on price.

Pros
  • Best price per gram
  • Micronized for mixability
  • GMP certified facilities
  • Multiple size options
Cons
  • Not Creapure® sourced
  • No third-party sport cert

RANK 04 / 05
Informed Sport Monohydrate
★★★★☆ 4.4 / 5.0
Momentous Creatine Monohydrate
Type: Creatine Monohydrate Dose: 5 g / serving Price/serving: ~$0.67 Servings: 45

Momentous has become the go-to brand for performance-focused researchers and physicians, partly due to Dr. Andrew Huberman's endorsement of their protocols. Informed Sport certified with Creapure® sourcing. Premium packaging and branding; solid product with no corners cut — though you pay for the positioning.

Pros
  • Creapure® sourced
  • Informed Sport certified
  • Physician-trusted brand
Cons
  • Highest cost per serving
  • Fewer servings per tub

RANK 05 / 05
Creatine HCl Informed Sport
★★★★☆ 4.2 / 5.0
Kaged Creatine HCl
Type: Creatine HCl Dose: 750 mg / serving Price/serving: ~$0.40 Servings: 75

Creatine hydrochloride (HCl) binds creatine to hydrochloric acid, dramatically increasing water solubility. The result: a smaller effective dose (~750 mg vs. 5 g) with near-zero bloating or GI discomfort. Best choice for those who experience digestive issues with monohydrate. Note: direct muscle uptake equivalence to monohydrate has not been confirmed in head-to-head RCTs.

Pros
  • Minimal GI side effects
  • High water solubility
  • Small dose convenience
  • Informed Sport certified
Cons
  • Less RCT evidence than mono
  • Higher cost per equivalent dose

Dosing Protocol: Loading vs. Maintenance

Protocol Guide

Loading Phase (Optional)

Take 20 g / day split into 4 × 5 g doses for 5–7 days. This saturates muscle creatine stores rapidly. GI discomfort is common; reduce to 10 g/day if needed. After loading, drop to maintenance dose.

Maintenance Phase

Take 3–5 g / day consistently. No loading required — daily maintenance achieves full saturation in ~28 days. Take with or without food. Post-workout with carbohydrates may marginally improve uptake via insulin-mediated creatine transport.

Timing

Daily consistency matters more than exact timing. Post-workout is backed by one head-to-head RCT (Antonio & Ciccone 2013). Morning with breakfast is equally effective for non-training days.

Cycling

Not necessary. No evidence supports creatine cycling. Long-term continuous use (5+ years studied) shows no adverse effects in healthy individuals. Endogenous creatine production resumes normally if you stop.

Frequently Asked Questions

What is the best form of creatine to take?
Creatine monohydrate is the gold standard. It has the most peer-reviewed evidence (500+ studies), highest purity, and lowest cost per gram. Creatine HCl is more soluble and easier on digestion — but current evidence does not show superior muscle uptake compared to monohydrate in head-to-head trials.
Do I need to do a loading phase?
No. Loading (20 g/day for 5–7 days) saturates muscle creatine stores faster but is not required. Taking 3–5 g/day consistently achieves the same saturation within 28 days. Loading can cause GI discomfort in some individuals; maintenance dosing avoids this entirely.
Is creatine safe for long-term use?
Yes. Creatine is one of the most extensively studied sports supplements. Research spanning up to 5 years shows no adverse effects on kidney or liver function in healthy individuals. The International Society of Sports Nutrition (ISSN) classifies creatine as safe and effective. Individuals with pre-existing kidney disease should consult a physician before use.
When should I take creatine — pre- or post-workout?
Post-workout is marginally superior based on current evidence. Antonio & Ciccone (2013) showed greater lean mass and strength gains with post-workout dosing vs. pre-workout in a controlled trial. However, daily consistency is far more important than timing — take it whenever you'll remember to take it daily.
Does creatine cause hair loss or raise DHT?
Evidence is weak and not replicated. One 2009 study (van der Merwe et al.) in 20 rugby players showed a transient DHT increase. No subsequent study has replicated this finding, and no human study shows creatine supplementation causes hair loss. Current scientific consensus does not support a meaningful link between creatine and androgenic hair loss.
