Under physiological conditions, more than 98% of the total GSH pool exists in the reduced form, thereby shaping cellular redox potential and influencing proliferation, differentiation, and cell death 5 .Although the GSH/GSSG ratio has long been regarded as an indicator of cellular redox status, recent live-cell studies using genetically encoded redox sensors indicate that increases in GSSG are typically transient and compartmentalized rather than sustained intracellular accumulations 6,7
Other risk factors include age over 50 (reduced gastric acid impairs absorption), proton pump inhibitor use, prior gastric surgery, and Type 1 diabetes
Understanding selection criteria helps determine whether HCG deserves consideration in your protocol
