Comparing E415 - Xanthan gum vs E409 - Arabinogalactan

Is xanthan gum bad for you?

No—at typical food levels it isn’t considered harmful; it’s approved for use in the U.S. and EU. Very high intakes can cause gas or a laxative effect in some people.

Is xanthan gum safe?

Yes—xanthan gum (E415) is approved by regulators like the FDA and EFSA and is considered safe at normal food-use levels. Large supplemental amounts may cause digestive upset, and xanthan-gum–based thickeners are not recommended for premature infants.

What is xanthan gum made from?

It’s a polysaccharide made by fermenting simple sugars (often from corn, sugarcane, or wheat) with the bacterium Xanthomonas campestris, then precipitated, dried, and milled into a powder.

Is xanthan gum bad for dogs?

No—it's not considered toxic to dogs, and small amounts used in pet foods are generally safe. Large amounts may cause diarrhea or gas, so avoid overuse and consult a vet if your dog has GI sensitivities.

What does xanthan gum do?

It works as a thickener, stabilizer, and emulsifier—adding viscosity, suspending particles, and preventing separation. In gluten-free baking it helps bind dough and improve texture, and it’s shear‑thinning so it pours easily but thickens at rest.
