Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to find out if dairy is a good source of choline compared to eggs. The main questions it aims to answer are:

* How the body uses choline; and,
* What effect WPPC has on choline metabolism.

Researchers will compare Whey Protein Phospholipid Concentrate (WPPC) to whole egg powder to see if WPPC is as effective as eggs.

Participants will drink a chocolate-flavored drink mixed with either WPPC or whole egg powder.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is intended to evaluate the bioavailability and metabolism of choline in WPPC compared to the most commonly -used food for bioavailable choline, whole egg. The intent of the evaluation is to improve the knowledge of how WPPC contributes to the nutritional needs and health of postmenopausal women.
