Supplementation Efficacy in Health Adults on Plasticizer RemovalNCT07714135
Evaluation of an Oat Fiber Supplement on Health
A study testing Oat Fiber in people with Supplementation Efficacy in Health Adults on Plasticizer Removal, run by California Polytechnic State University-San Luis Obispo at 1 site in United States.
Trial summary
The purpose of the study is to determine whether short-term use of an oat fiber supplement reduces exposure to your urine levels of dietary chemicals like bisphenol A (BPA). This study will also examine whether supplementation with NeutraOat oat fiber influences blood glucose levels using continuous glucose monitoring. Read more about this study

About this study
The purpose of the study is to determine whether short-term use of an oat fiber supplement reduces exposure to your urine levels of dietary chemicals like bisphenol A (BPA).
This study will also examine whether supplementation with NeutraOat oat fiber influences blood glucose levels using continuous glucose monitoring.
Read the detailed description
The purpose of this study is to evaluate whether short-term supplementation of oat fiber reduces exposure to plasticizers following a controlled dietary exposure and whether any resulting changes influence glycemic responses.

- Oat Fiber, Placebo
- Keywords
- Oat FIber, supplementation, metabolic health, BPA
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Oat FiberDietary supplement
4 grams of supplementation by capsule per day for two days

How can a doctor refer a patient or contact the research team?
Contact Todd Hagobian, PhD (805-756-7511, thagobia@calpoly.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Urine Plasticizer Concentration (time frame: Urine samples will be take over the course of three weeks.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jul 2026.
