Clinical Trial Summary

This study aims to conduct a randomized cross-over study investigating the release of cranberry polyphenols from chewing gum formulated with polyphenol-lecithin precipitate (PLP). 10 participants will be on study for up to 2 weeks and will each complete 2-30 minute study intervention visits.

Description:

This study is intended to evaluate the bioavailability of a dietary supplement, cranberry PLP, compared to another dietary ingredient, cranberry extract. The intent of the evaluation is to provide preliminary data for future evaluation of cranberry PLP on the normal structure or function in humans, which includes the effect of cranberry PLP on oral health. Participants will be asked to refrain from eating, drinking, or using tobacco products, and vigorous exercise for 1 hour before the intervention period. Participants will also be asked to avoid chewing gum 48 hours before the intervention. Water is acceptable up until 10 minutes before sample collection. Participants will be given these instructions during the informed consent process, and will be sent a reminder email about study protocols at least 72 hours in advance of the study visit. If their second visit is 48 hours after their first, the investigators will remind them of these restrictions at the end of their first visit. On the day of each intervention and sampling period, participants will be asked to visit the Bolling Laboratory at the Department of Food Science adhering to the dietary guidance described above. Participants with appliances or dentures will be asked to remove them during sampling periods. Then, participants will chew the intervention or control gum for a total of 60 minutes while providing chewed gum and saliva samples at specified intervals throughout this time. Participants will come back to the Bolling Laboratory at a later time, a minimum of 48 hours after the last sampling period, to chew the other gum in the same manner as the first sampling period.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Concentration of Polyphenols	Participant chewed gum samples will be measured for polyphenol concentration.	Baseline before chewing gum; then 1, 3, 6, 10, 15, 21 minutes after start of chewing gum.
Secondary	pH	Participant saliva samples will be measured for pH.	Baseline before chewing gum and approximately 60 minutes after start of chewing gum.
Secondary	Concentration of Polyphenols	Participant saliva samples will be measured for polyphenol concentration.	Baseline before chewing gum and approximately 60 minutes after start of chewing gum.
