Our editorial standards
Articles cite peer-reviewed studies by PubMed ID where claims warrant it. Health claims are limited to what the trials actually support. We don't speak in absolutes about therapeutic effects, and we don't substitute for a physician's care. The blog complements the Ones product but stands on its own as a research resource.
