Evaluation of Vitamin A Absorption From Fortified Bouillon

This study is being conducted to help characterize the absorption of 3 different formulations of VAP (PFH-VAP and BASF-VAP250 vs a positive control) when prepared as broth with an oil dose containing VAP or placebo (referred to as the "study treatments") and consumed by healthy adult women of reproductive age (ages 18 - 49 years).

Participants will undergo 3 treatment periods and will be blinded to treatment sequence using a 3-period, 3-treatment crossover design to receive all 3 treatments. All 3 treatment periods will include blood sampling to measure VA levels from pre- through 24 hours post-broth consumption.
