Oral glutathione is less effective due to poor absorption
Calf muscles (soleus, plantaris, and gastrocnemius muscles of lower hind-limb) were collected from male C57BL/6J mice (8-weeks old) of four experimental groups ( n =3/group): control, 5 days of muscle-disuse induced by tail suspension, and 3 days pre-administration of GSSSG or LASSS (about 50 g/g body weight per day in drinking water) followed by 5-days muscle disuse without the GSSSG and LASSS supplementation

The cysteine in whey protein is largely present as glutamylcystine, which is resistant to digestive degradation and serves as an efficient substrate for glutathione synthesis [22]

Moreover, although PET-based fluorescence switching enables effective off-on activation, the extent of initial quenching and the magnitude of signal recovery upon activation are highly dependent on the COFs electronic structure and local microenvironment, necessitating precise molecular engineering to balance diagnostic signal-to-noise ratio with therapeutic output
