Because of its use as a thickening agent, it only makes sense that xanthan gum could be useful in improving the texture of smoothies. The idea has gained traction on TikTok, where a quick search for xanthan gum smoothies or protein shakes yields countless results. In a video shared last year, for example, TikToker Sarah Ryan recommended blending frozen strawberries, açaí purée, vanilla protein powder, honey, and a splash of your preferred milk with a dash of xanthan gum to make a thick, practically fluffy smoothie.
According to Total Shape, xanthan gum is particularly helpful for binding smoothies that contain a mixture of protein powder and other natural ingredients, which tend to separate from one another, even after blending. The xanthan gum emulsifies everything together and ensures a consistently smooth texture in your beverage.
When adding xanthan gum to your smoothies for the first time, be sure not to overdo it: Using too much xanthan gum can result in a smoothie with an unpleasantly gummy texture, per Spin the Food. For the perfect drink, Wellnessed recommends starting with ⅛ to ¼ of a teaspoon of the additive, about as much as a generous pinch. Now, all the best healthy smoothie recipes can be just a little thicker. Now, why not try something fun like a sweet potato smoothie recipe?
