Health notes

Aspartame is approved by the U.S. Food and Drug Administration (FDA) as a food additive. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated aspartame and set an acceptable daily intake. The European Food Safety Authority (EFSA) has also concluded it is safe for consumption at typical levels. In 2023, the International Agency for Research on Cancer (IARC) classified aspartame as "possibly carcinogenic to humans" (Group 2B), while JECFA reaffirmed its existing acceptable daily intake. This highlights mixed evidence and ongoing scientific discussion.

Allergen info

Aspartame is not a major allergen. However, individuals with the genetic disorder phenylketonuria (PKU) must avoid phenylalanine, which is a component of aspartame, and products containing aspartame are required to carry a warning label.
