Adherence Marker Study

Volunteers Needed

Individuals are being recruited for a study on developing an adherence marker compound for tracking consumption of nutrient supplements. 

Interested individuals will be prescreened by phone using a prescreening questionnaire; those who may be eligible will be scheduled for an in-person screening visit at the Ragle Human Nutrition Center on the UC-Davis campus.  Eligible participants will be enrolled in the study for 15 consecutive days.

Participation involves eating a nutrient supplement that contains two adherence marker compounds daily for 10 days and collecting urine samples on 6 days over the course of the study. The adherence marker compounds are an FDA-approved food additive and a naturally occurring compound in grapes. 

To qualify for this study you must:

  • be healthy non-pregnant, non-lactating women

  • be between 18-45 years of age

  • have a BMI between 18.5 and 25.0 kg/m2
