Common benefits or risks of Xanthan Gum
Several studies have shown that Xanthan Gum is ‘safe’ in normal doses, for humans and pets.
Risks: That said, Xanthan Gum requires a ‘medium’ to grow and often the medium of choice is a carbohydrate like corn, soy, dairy, or wheat, all of which are potentially allergenic substances, especially if fed over long periods of time.
