Dietary supplements are rapidly growing consumables that impact the daily lives of many people.  CTI participates in Expert Review Panels (AOAC), proficiency testing (NIST, AOCS), as well developing validated methods for dietary supplement analysis. Involvement in such organizations keeps our finger on the pulse of the field.
