Phosphatidylcholine, an edible carrier for nanoencapsulation of unstable thiamine.

Lipid nanoparticles have been used for carrying different therapeutic agents because of the advantage in improved absorption, bioavailability, targeted deliveries and reduction in the quantity of drugs required. The aim of the study was to prepare and characterize nanoliposomes containing thiamine hydrochloride and study their physicochemical stability as this vitamin is highly unstable. Phosphatidylcholine (PC) was used as an edible encapsulant.
