What Is Neotame?
Neotame is a structural analog of aspartame but far more potent — approximately 7,000-13,000 times sweeter than sucrose. Unlike aspartame (E951), it does not release significant phenylalanine on metabolism and does not require PKU labeling. It is heat-stable in some applications. JECFA established an ADI of 0–2 mg/kg body weight. EFSA reviewed neotame in 2007 and confirmed the ADI. Approved in EU, USA (2002), Australia/NZ, and Canada. Due to its extreme sweetness, it is used at very low concentrations, making its use highly efficient relative to other sweeteners.
? Did You Know?
Neotame isn't just a food additive — it's also used in medicine.
To reach the Acceptable Daily Intake limit, a 60kg adult would need to consume approximately ~171 cans of neotame-sweetened beverage (355ml) in a single day. (This is a mathematical illustration, not a safety recommendation.)
Neotame is fully synthetic — it doesn't exist in nature and is manufactured entirely through chemical processes.

Everyday Perspective
For a 60kg adult, this limit is roughly equivalent to consuming:
Natural Occurrence
This additive is not known to occur naturally in significant quantities.
Manufacturing
Synthesized from aspartame by adding a 3,3-dimethylbutyl group. This modification makes it much sweeter and eliminates the need for phenylketonuria (PKU) warnings.
Applications Beyond Food
Sweetener in chewable tablets and liquid medicines
