If your body already struggles to manufacture or regenerate glutathione efficiently, beginning with the active, reduced form (GSH) makes biological sense
The cellular studies using CHO cells indicated that the pre-treatment of DSePA significantly upregulated the mRNA expressions of seleno-GPxs ( GPx1 , GPx2 , GPx3 , and GPx4 ), increased total GPx activity, and concurrently improved the viability of irradiated cells with a dose modification factor of 1.53 [85]
