Official title
Evaluation of Vitamin A Absorption From Fortified Bouillon Using Post-prandial Retinyl Ester Response in Comparison With an Oil-based Vitamin A Supplement
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to measure how well different formulations of vitamin A (VA) are absorbed by the body when they are added to bouillon (broth) as vitamin A palmitate (VAP). Fortifying bouillon cubes with VA is one potential approach to addressing VA deficiency, which is a major public health issue in many low- and lower-income countries. The main question this study aims to answer is to compare the amount of VA that is absorbed by the body from three different VAP formulations that are added to bouillon. Participants will consume different formulations of VA and have multiple blood collections.
