What Is Carrageenan?

A family of sulfated polysaccharides extracted from red seaweed. Used as a thickener, stabilizer, and emulsifier in dairy products, plant-based milks, deli meats, and infant formula.

Mechanism of Action

Food-grade carrageenan (undegraded, molecular weight >100 kDa) is not absorbed systemically. Concerns center on degraded carrageenan (poligeenan, MW <50 kDa), which has been shown to cause intestinal inflammation in animal models. Some researchers (Tobacman, 2001) argue that food-grade carrageenan may degrade in the acidic stomach environment, though this is debated.
