Evaluation of the relative potency factor (RPF) of the NANO formulation (dose-response curve with crosses) in respect to the BULK form (dose-response curve with triangles) of β-carotene. RPF was calculated at the effective concentration at 50 % (EC50). RPF of the nano-encapsulated β-carotene was 6*10−4 (BMD modelling by using PROAST software).
