The facts: Potassium Sorbate is restricted in European Union (ADI 3 mg/kg body weight; maximum permitted levels vary by food category), Australia, though the FDA still allows it in the US. We can't tell you whether it's safe for your pregnancy — that's a conversation for your OB-GYN or midwife. What we can do is show you the regulatory facts and flag Potassium Sorbate on any product's label so you can decide with your provider. Commonly found in: Bread and bakery products, Cheese, Wine.

Potassium sorbate is the potassium salt of sorbic acid, a naturally occurring short-chain fatty acid originally derived from the mountain ash berry (Sorbus aucuparia). Commercial potassium sorbate is synthetically produced by reacting sorbic acid with potassium hydroxide. It is the most widely used food preservative globally.
Potassium sorbate is a broad-spectrum antimicrobial preservative effective against yeasts, molds, and some bacteria. Used in a wide range of foods including breads, cheese, wines, dried fruits, juices, and personal care products. It is effective at lower concentrations than benzoates and has a neutral flavor profile.
Potassium sorbate has a generally good safety profile compared to other synthetic preservatives. EFSA's 2015 re-evaluation maintained the ADI at 3 mg/kg body weight, finding no significant carcinogenicity or genotoxicity. However, some human and in vitro studies have documented concerns. A 2010 study in Toxicology in Vitro found potassium sorbate was genotoxic (caused DNA strand breaks) in human blood cells at concentrations achievable in food. The study found it damaged peripheral blood lymphocytes. A 2014 study in Food and Chemical Toxicology found potassium sorbate caused DNA damage in human lymphocytes at food use concentrations. Contact dermatitis and allergic reactions from topical use are documented. At very high doses in animal studies, liver and kidney effects have been observed. The general regulatory consensus is that potassium sorbate is one of the safer food preservatives, but the in vitro genotoxicity findings deserve attention.
