Supplements aren't FDA-rated like drugs, so we assess brands on the real quality signal: independent third-party testing and certifications — NSF, NSF Certified for Sport, USP Verified, Informed Sport, and cGMP manufacturing.

The FDA does not approve or recall-rate supplements the way it does prescription drugs, so a recall-safety score doesn't apply. Instead we look at the signal that actually separates supplement quality: independent third-party testing and certification. The strongest marks are NSF and NSF Certified for Sport (screens 280+ banned substances), USP Verified, and Informed Sport/Choice; cGMP manufacturing and per-batch Certificates of Analysis add assurance. We surface what each brand is verified for rather than invent a single score. This is general reference, not medical advice — always consult a professional.
