Official title
Novel 13C Carotenoids for Absorption and Metabolism Studies in Humans.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Tomatoes contain several compounds which may be beneficial for human health and prevention of disease, although this relationship is poorly understood and very controversial. This study uses a new technology to study the absorption and metabolism of three different compounds found in tomatoes. These compounds are called: phytoene, phytofluene, and lycopene. We hypothesize that by studying the absorption and metabolism of these compounds, we may be able to understand how the compounds may influence health and disease processes.
