What is Neotame?
Neotame is a synthetic dipeptide sweetener — a derivative of aspartame with a 3,3-dimethylbutyl group added to block aspartame's metabolism, preventing the release of phenylalanine. This means it is safe for people with phenylketonuria (PKU), unlike aspartame. It is approximately 7,000-13,000 times sweeter than sucrose.
Why is Neotame used in food?
Neotame is used as a high-intensity sweetener in sugar-free and reduced-calorie foods and beverages. Its extreme potency (one of the most potent sweeteners approved) means very small quantities are needed. Unlike aspartame, it does not require a PKU warning label.
What regulators have flagged about Neotame
Neotame is one of the newer synthetic sweeteners with a shorter safety track record. A 2023 study published in Frontiers in Nutrition found that neotame damaged intestinal epithelial cells in vitro and disrupted the gut microbiome in mice — including reducing beneficial bacteria and increasing bacterial invasion of intestinal cells. The study observed effects at concentrations that could be achievable through high consumption of neotame-containing products. The FDA has set an ADI of 0.3 mg/kg/day, one of the lower sweetener ADIs, reflecting a conservative safety margin. Limited long-term human safety data exist compared to aspartame, acesulfame K, or saccharin, which have been used for decades. EFSA's 2010 opinion found no safety concern at permitted levels. The Frontiers in Nutrition 2023 gut study represents new concerning findings that warrant further investigation.
