What is the difference between products or pills that people use as supplements that are labeled as “glutathione” or “cystine”?
A. Glutathione is produced within the cells (intra-cellularly). When taking a pill labeled “glutathione”, clinical and laboratory studies demonstrate that oral glutathione is NOT absorbed but will be eliminated by the liver through the bile before ever reaching the systemic circulation (blood stream). Cystine is not well absorbed when taken by mouth. Injectable glutathione also has limited benefits. It is unstable in the blood stream. By the time it gets to the cell, much of it gets degraded, and much of this remaining glutathione cannot effectively pass through the cell membrane.

Clinical studies have demonstrated that oral cystine supplementation (NAC or N Acetyl L-Cysteine) is NOT effective in increasing cystine levels within the cell, and has also not been associated with significant increases in glutathione levels within the cell. The three bioactive proteins supplied by bioactive whey protein constitute a “natural delivery system” from these cystine precursors to the cell (in ord
