Lutein has various biological activities, its application in food and pharma industries are limited due to poor aqueous solubility, stability, and bioavailability. To achieve various benefits, lutein-poly (lactic-co-glycolic acid) (PLGA)-phospholipid (PL) nanocapsules were prepared. Lutein-PLGA NCs (+PL) were synthesized, characterized and its bioavailability was studied in vitro and in vivo. The cellular uptake and anti-proliferative activity were analyzed in Hep G2 cells. The mean size and zeta value of lutein-PLGA NCs (+PL) were 140 ± 6 nm and − 44 mV. The amorphous nature of lutein in PLGA NCs (+PL) was confirmed by XRD and DSC. In vitro lutein release kinetics showed an initial burst followed by sustainable release up to 86%. In vitro bioavailability showed 62.7% higher lutein bioaccessibility than lutein in free form. The AUC of lutein after single oral dose of lutein-PLGA NCs (+PL) revealed 3.91 …
