Determination of the Biological Activity of Enriched Serums on Healthy Volunteers After Consumption of the Kera-Diet® Ingredient

The clinical study will be conducted in two phases. The first phase will aim at characterizing the metabolites present in human serum after consumption of the Kera-Diet® ingredient and at determining the overall absorption peak of the tested ingredient. The second phase will involve collecting sera enriched with metabolites at the absorption peak, following the ingestion of the ingredient. Subsequently, the final objective will be to characterize the influence of these sera enriched with metabolites of interest on the behavior of human skin cell and intestinal epithelial cell cultures.
