The rationale for people with Autism taking Immunocal is based on the evidence contained in the abstracts below, which describe the role of oxidative stress, toxins, and abnormal glutathione levels in this disorder. This may be a contributory factor in the process. Immunocal provides cells with the precursors, or building blocks, needed to produce glutathione. Glutathione plays a crucial role in mediating free radical damage, maintaining the oxidant/anti oxidant balance, and removing toxins in the body. This may result in improve measures of autistic behavior.
