The packs look good IMO however I have not found much evidence that
glutathione enters the blood intact...unless one hass engaged in quite a bit
of grain consumption which can lead to permeable gut situations.  Providing
the raw materials (cysteine, glutamine etc.) and consuming products like
alpha lipoic acid (a fat and water soluble antioxidant which increases the
production of GLU) SAME, and milk thistle among others have excellent
science behind them.  This is also another benefit of animal proteins VS
plant proteins, the former being much richer sources of sulpher cmino acids
which are important for this process.
