Oat Fiber Supplement for Reducing Dietary Chemical Exposure

This study is looking at whether taking an oat fiber supplement, called NeutraOat, can help reduce the levels of certain dietary chemicals, like bisphenol A (BPA), in your urine. Researchers also want to see if this supplement affects your blood sugar levels. You might be able to join if you are a healthy adult between 18 and 40 years old, have been weight-stable for the past six months, and don't smoke or have any chronic illnesses. The study aims to enroll 40 participants. Success in this study would mean that the oat fiber supplement helps lower the amount of these chemicals in your body. The current recruitment status is unclear.

Study design
This interventional study plans to enroll 40 healthy adults. Participants will receive either 4 grams of Oat Fiber or a placebo (an inactive substance) by capsule each day for two days.
What's involved
You would take a capsule daily for two days. Urine samples will be collected over three weeks, and your blood glucose levels will be monitored.
Compensation
Not stated in the trial record.
Follow-up
Urine samples will be taken over the course of three weeks after the two-day supplementation period.
