Is it true that Aspartame (Sugar Free Gold) is an excitotoxin?
No. An excitotoxin is a substance that reportedly over-stimulates brain and nerve cells. Critics have falsely claimed that ingestion of Aspartame (Sugar Free Gold) may result in high blood levels of aspartic acid, which would circulate to the brain and kill nerve cells. However, extensive scientific research has shown that it is not possible for a person ever to consume enough Aspartame (Sugar Free Gold) in the diet even over long periods of time to result in high blood levels of aspartic acid.
