Let’s clear up the misconception that exogenous supplements of glutathione are cheaper and more effective than endogenously produced glutathione. Cysteine Peptide (endogenous synthesis of glutathione) versus Liquid Glutathione (exogenous intake). Endogenous means produced within an organism, tissue, or cell. Exogenous means originating from outside a cell, tissue, or organism.
From the above, we can intuitively deduce that going by the endogenous route is the most efficient, more economical, and effective in terms of results. Glutathione degrades rapidly (due to its half-life nature) and by the time it completes its track through the digestive system, very little remains for absorption. Hence, to reach similar results, you may need to consume 20 capsules of liquid glutathione (500mg x 20) to obtain the same with 960mg of Cysteine peptide. Exogenous intake of glutathione encounters a significant barrier—the fragility of G hinders its crossing into cell membranes due to its rapid hydrolysis in circulating plasma.
In comparison, the robustness of Cysteine Peptide survives the gut to penetrate into our bloodstream. In the bloodstream, it is degraded rapidly by an enzyme called gamma-glutamyl transpeptidase found on the extracellular surfaces of our cells. This process yields glutamate, cysteine, and glycine. As a result, the cell surface provides the cells with the ingredients to synthesize glutathione.
In conclusion, AG-FACTOR™ is different from glutathione pills out there as AG-FACTOR™ teaches your body to be more intelligent to produce its own glutathione instead of forcing your body to absorb foreign-sources.
