What this is

Saccharin is a synthetic (non‑nutritive) sweetener (E 954) roughly 200–700 times sweeter than sucrose. It is a calorie‑free sugar substitute used in “diet” sodas, tabletop sweeteners (e.g. Sweet’N Low), and sugar‑free desserts or syrups. Global regulators regard saccharin as safe when consumed within approved limits. For example, the FDA and WHO consider it safe (it has GRAS/food‑additive status) and no warning labels are required. Early high‑dose rat studies linked saccharin to bladder tumors, but experts now agree that mechanism does not apply to humans. Consequently, IARC classifies saccharin (and its salts) as Group 3 (“not classifiable” for human cancer). Typical exposures from diet sodas or foods are far below the acceptable daily intake (ADI) established by regulators.
