The rationale for people with most neurodegenerative disorders, including Alzheimer's / Parkinson's Disease, taking Immunocal is based on the evidence contained in the abstracts & articles below, which describe the role of oxidative stress & the decrease of Glutathione in the brain. Other supporting abstracts can also be found.
Glutathione plays a crucial role in mediating free radical damage & maintaining the oxidant/anti oxidant balance. Since the Brain consumes about 20% of the oxygen utilized by the body, the potential for oxidative stress is high. When glutathione is depleted this tilts the balance in favor of the oxidants - resulting in oxidative stress. Immunocal provides cells with the precursors, or building blocks, needed to produce glutathione. This helps scavenge the free radicals and may slow down the degenerative process in Alzheimer's, Parkinson's Disease, as well as other neurodegenerative disorders.
