In 2011, researchers discovered that oral glutathione supplements or injections may reduce some of the effects of autism. However, the team did not specifically look at the children's symptoms for any improvement, so further research is needed to determine this effect.

Glutathione is an innate substance in the human body. In infants and young children, the content of glutathione in the body is highest, and it decreases with age. In nature, it mainly exists in animal liver, yeast, muscle and blood cells.
