Unraveling the Side Effects of Xanthan Gum

Xanthan gum, a common food additive, has carved out a niche for itself in various industries, from food and beverage to pharmaceuticals and cosmetics. Despite its widespread use, some potential side effects of xanthan gum warrant attention.

What is Xanthan Gum?

Before diving into the side effects of xanthan gum, let’s understand what it is. Xanthan gum is a polysaccharide, a type of sugar, produced by the fermentation of a carbohydrate with Xanthomonas campestris bacteria. Its excellent thickening and stabilizing properties make it a popular additive in various food products and industrial applications.

Common Uses of Xanthan Gum

You’ll often find xanthan gum in products like ice cream, sauces, gluten-free foods, personal care products, and even oil drilling operations due to its exceptional ability to thicken and stabilize mixtures.

Possible Side Effects of Xanthan Gum

Although xanthan gum is generally safe for consumption and topical use, some individuals may experience certain side effects.

Digestive Issues

One of the most commonly reported side effects associated with xanthan gum is digestive discomfort. Since it’s a type of fiber, it can cause bloating, gas, and laxative effects, especially when consumed in large quantities.


While rare, some individuals may be allergic to xanthan gum. Symptoms can range from skin rashes to difficulty breathing. If you notice any allergic reactions after consuming a product containing xanthan gum, consult with a healthcare professional immediately.

Xanthan Gum and Dietary Concerns

Xanthan gum has a unique place in the food industry due to its vegan, gluten-free, and low-calorie properties. However, it’s essential to note that its dietary compatibility doesn’t guarantee it’s free from side effects.

Impact on Blood Sugar

Xanthan gum can slow digestion and impact how quickly sugar enters your bloodstream, potentially aiding in blood sugar control. While this might benefit individuals in managing their blood sugar levels, abrupt changes in blood sugar can cause issues in some people.

Xanthan Gum on a Gluten-Free Diet

Xanthan gum is often a lifesaver in gluten-free baking as it provides the elasticity that gluten offers in traditional baking. However, those with severe gluten sensitivity or celiac disease might react to xanthan gum if it’s produced from a wheat-derived medium.

Precautions When Using Xanthan Gum

While the potential side effects of xanthan gum should not be ignored, it’s important to remember that these reactions are relatively rare and typically linked to excessive consumption. It’s always advisable to use food additives like xanthan gum in moderation and heed any discomfort or reactions your body may show.

Other Health Considerations Related to Xanthan Gum

While xanthan gum is generally safe for most people when consumed in moderate amounts, some health considerations need to be kept in mind.

Potential for Choking

Due to its thickening properties, xanthan gum can potentially pose a choking risk, especially if it isn’t mixed well with liquids before consumption. This risk is especially relevant for elderly individuals and those with swallowing difficulties.

Impact on Gut Health

There is ongoing research into how food additives like xanthan gum may affect our gut health. Some studies suggest that consuming large amounts of these additives may negatively impact the balance of our gut flora.

Xanthan Gum in Non-Food Items

It’s also important to note that xanthan gum is not only found in food but is also a common ingredient in many non-food items, which can also lead to side effects.

Use in Cosmetics and Skin Products

Xanthan gum is often used as a binder, emulsion stabilizer, and skin-conditioning agent in cosmetics and skin products. However, some people may experience skin irritation or other allergic reactions to these products.

Use in Medication

Xanthan gum is also used as a filler in some medications. If you’re sensitive or allergic to xanthan gum, it’s essential to check the ingredient list of any medication you take.


While xanthan gum is generally safe and beneficial for a variety of applications, like with any substance, it’s not without potential side effects. By understanding what xanthan gum is and how it affects your body, you can make informed decisions about its consumption. As always, if you experience any adverse effects from consuming xanthan gum, it’s essential to seek medical advice.
