What is methanol and does it pose a problem in consuming aspartame?

Upon digestion, aspartame breaks down into its components - the amino acids, aspartic acid and phenylalanine, and methanol - which are then absorbed and used into the body. These components are used in the body in exactly the same ways as when they are also derived from common foods and beverages. Neither aspartame nor its components accumulate in the body over time.

Methanol is a natural and harmless breakdown product of many commonly consumed foods and is part of the normal diet. The methanol produced during the digestion of aspartame is identical to that which is obtained in much larger amounts from many fruits, vegetables and their juices. In fact, a glass of tomato juice provides 6 times as much methanol as an equal amount of beverage sweetened with aspartame.

Regardless of its source, methanol is further broken down through normal body processes. Numerous scientific studies have shown that the methanol derived from aspartame could not possibly reach harmful levels.
