Well my understanding is the glutathione has great properties that can help boost your immune system. Because of CF digestion problems, many CFers don't produce enough of it, even when they take enzymes. This may contribute to why many of us are colonized with pseudamonus (sp?)
Some CFers take MedImmune Plus which has pre-cursors to glutathione (you can't buy gluthatione... only it's pre-cursors) such as L-Lysine.
Others I have heard nebulize it........ or other glutathione pre-cursorers.
So I figured I would give it a shot...... the L-Lysine that is. Plus I"m trying to increase intake of avocado and broccoli which can help as well.
