Why BioRestLab
Most recovery and sleep content online does not clearly explain how products are evaluated. BioRestLab applies a transparent, criteria-based approach: every rated product is assessed against six weighted criteria using published research, manufacturer specifications and certifications, and systematic analysis of verified-purchase owner feedback. We do not claim in-house physical testing when we have not performed it. Read our full rating methodology, or learn more about who we are.
