Carrageenan
The short version
A seaweed-derived gelling agent — central to plant milks, ice cream, and processed meats; under scrutiny for gut microbiome effects.
A seaweed-derived thickener. It's approved and widely used, but some studies suggest a broken-down form can irritate the gut, and that debate isn't fully settled. That uncertainty is why we flag it.
Safety profile
ADI not specified by JECFA but use is restricted in infant formula in the EU and several other jurisdictions. The degraded form (poligeenan, not approved for food) is an established gastrointestinal inflammatory agent in animal models. Whether food-grade carrageenan has similar effects in humans is debated; recent in-vitro and animal studies have raised concerns about gut microbiome and intestinal inflammation.
