Powder XRD patterns of sodium selenite (a), the lyophilized physical mixture of formulation constituents (b), lyophilized placebo liposomes (c), and Man-Lip-Se (d). Crystallinity can be seen with the lyophilized sodium selenite and the physical mixture, whereas the lyophilized placebo- and selenium-loaded formulated liposomes display amorphous characteristics. Type: 2Th/Th locked; Start: 5.000°–End: 39.996°; Step: 0.010°; Step time: 96 s; Temp: 25°C (Room); Time started: 4 s; 2-Theta: 5.000°–Theta: 2.500°
