Compared with standard glutathione (500 mg), LipoMicel at a lower dose (300 mg) increased iAUC and C max by ~2.49-fold and ~2.43-fold, respectively, and when dose-normalized (to a 300 mg equivalent), incremental systemic exposure and peak levels were up to ~4-fold higher, supporting greater absorption per unit dose. The findings indicate LipoMicel is a promising delivery method for oral glutathione, though the researchers added larger, long-term studies are still needed
