How We Rank Creatine Supplements
Every product is evaluated on three criteria:
- Cost per clinically-effective daily dose. Not cost per pill or cost per bottle. We calculate what it actually costs per day to take the dose used in clinical trials.
- Third-party certification. USP Verified, NSF Certified for Sport, and ConsumerLab Approved indicate independent testing for purity, potency, and contaminants.
- Bioavailable form. We prioritize products using the specific chemical form shown to be most effective in published research.
Rankings are not influenced by affiliate commissions. We earn the same commission regardless of which product you choose. Read our full methodology.
