Bioenhancer‐Driven Modulation of Membrane Dynamics Improves B‐Vitamin Uptake in Caco‐2 Cells

open access: yesChemFoodChem, Volume 2, Issue 2, June 2026.
Natural bioenhancers such as extracts from ginger, turmeric, black pepper, and spearmint increase the uptake of vitamins B1, B5, B6, and B7 in Caco‐2 cells. Micellized formulations further increase efficacy. These findings indicate that altered membrane fluidity contributes to enhanced cellular absorption, providing a new route to improve vitamin B ...
