ClinConnect Summary

This clinical trial, called "Dairy Choline Bioavailability," is exploring whether dairy products, specifically a type of whey protein, are as good a source of choline as eggs for post-menopausal women. Choline is an important nutrient that our bodies need for various functions, and the researchers want to understand how our bodies use it. Participants will be asked to drink a chocolate-flavored beverage that contains either whey protein phospholipid concentrate (WPPC) or whole egg powder to see how effective each source is for choline absorption.

To be eligible for this study, women aged 51 to 70 who are post-menopausal can participate, provided they are not allergic to dairy or eggs and have maintained a stable body weight for the last six months. Participants will need to complete health surveys, keep a food diary for four days, and provide samples of blood, urine, and stool at the start and after 10 days of drinking the study beverages. It's important for participants to be in good health, free from certain medical conditions, and willing to avoid rigorous exercise during the study. This research could help us understand more about the best sources of choline for women in this age group.
