The Claim

Following daily oral dosing at 80.4 mg/kg/day for 40 days, sucralose is metabolized in the rat intestine into two previously unreported acetylated metabolites, challenging prior assumptions that it is excreted unchanged.

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

When rats eat sucralose every day for 40 days, their intestines turn it into two new substances that scientists didn’t know existed before—this means it’s not just passing through their bodies unchanged like we thought.

1 study
  1. Study: Intestinal Metabolism and Bioaccumulation of Sucralose In Adipose Tissue In The Rat

    This study gave rats the same artificial sweetener (sucralose) every day for 40 days and found that their bodies changed it into two new substances they didn’t know about before — meaning it’s not just passed through unchanged like people thought.
