Psyllium Husk vs Xanthan Gum: Which is Better For Your Needs?

Are you seeking digestive wellness and other ways to manage your health? Maybe you are on a quest for gluten-free and alternative dietary options? If so, you’ve probably been comparing psyllium husk vs xanthan gum.

These ingredients have found their way into the kitchens of health enthusiasts, home bakers, and those with dietary restrictions. They can both affect gut health and play a role in gluten-free cooking, but their benefits and potential health impacts differ significantly.

What is Psyllium Husk?

Psyllium husk is derived from the seeds of the Plantago ovata plant, an herb native to India and the Mediterranean region. 

The outermost covering of the seeds is ground to create a fine, powdery substance. This natural product is commonly used in the food industry and in many health and wellness applications.

It has been used for centuries as a natural remedy for various digestive issues, thanks to its high dietary fiber content. You can find it today in fiber supplements like Metamucil.

Health Effects of Psyllium Husk 

Psyllium husk is well-known for its impressive health benefits, primarily attributed to its high content of soluble fiber. Here are some of the key advantages associated with consuming psyllium husk:

Gut Guardian

Your gut is your body’s defender and nutrient processor, and psyllium husk is here to support it. By acting as a prebiotic, it nourishes the beneficial bacteria in your gut, paving the way for a healthier gut microbiome (1). 

A healthy gut means better digestion and a stronger immune system—both crucial for your overall well-being.

Digestive Harmony

Psyllium husk plays the role of a natural laxative and a trusty remedy for those uncomfortable bouts of constipation. How does it work, you wonder? The secret lies in its soluble fiber, which soaks up water and creates a gel-like substance. 

This gel softens stool, making it much easier to pass. So, it not only promotes regular bowel movements but also provides welcome relief from constipation (1).

Diarrhea Tamer 

Surprisingly, psyllium husk isn’t just about addressing constipation. That same gel-like quality that works wonders for constipation also helps manage diarrhea. It can absorb excess water, which comes in handy when you’re dealing with loose or watery stools (2).

This dual action makes psyllium husk beneficial to people with Irritable Bowel Syndrome (IBS).

Blood Sugar Balance 

Got blood sugar concerns? Psyllium husk to the rescue! Thanks to its soluble fiber, it can help regulate blood sugar levels by slowing down the absorption of glucose (3). 

This can be very helpful if you’re dealing with diabetes or at risk of developing the condition.

Heart Health 

When it comes to matters of the heart, psyllium husk is a champion. 

Studies have shown that it can lower cholesterol and triglyceride levels, reducing the risk of heart disease (4). In fact, the Food and Drug Administration (FDA) concluded that 7g of psyllium husk per day (about 1.5 tablespoons) will lower cholesterol (5).

Colon Companion

Psyllium husk may also have a protective effect on your colon. As mentioned above, it can help prevent or relieve symptoms of IBS and other inflammatory bowel conditions. Some older animal studies also showed protection from colon cancer (6).

In addition, adequate fiber intake, such as that from psyllium husk, may reduce the risk of developing diverticula (small pouches in the colon) and the inflammation known as diverticulitis.

Potential Risks of Psyllium Husk

It’s important to note that while psyllium husk offers numerous health benefits, there are potential risks. 

Stomach Pains 

For some individuals, introducing psyllium husk to their diet may lead to minor gastrointestinal discomfort such as bloating, gas, cramps, or changes in bowel movements. Drinking enough water is often key to preventing discomfort.

Allergy Effects 

While allergic reactions to psyllium husk are rare, it’s important to be aware that they can occur. Allergic responses may manifest as skin rashes, hives, or other allergy symptoms. 

Medication Absorption 

If you’re currently taking medications, it’s important to exercise caution when incorporating psyllium husk into your diet, as it could affect the way your body absorbs certain medications including some for cholesterol and diabetes.

Choking Risk 

Another essential safety note is that psyllium husk can turn into a gel-like substance when not correctly mixed with water, which could pose a choking risk. To avoid this, always ensure you’re following the recommended instructions before consuming psyllium husk. 

GI Blockages 

If you have certain medical conditions, such as gastrointestinal obstructions or narrowing, psyllium husk may not be for you.

With any of these risks, it’s advisable to seek the guidance of a healthcare professional before incorporating psyllium husk into your diet. 

Culinary Uses of Psyllium Husk

Psyllium husk powder is useful in gluten-free cooking and baking. The soluble fiber in psyllium husk has an incredible water-absorbing capacity, giving your recipes the necessary structure and texture.

The fiber creates a gel-like consistency when mixed with water. This property helps in binding ingredients together, replicating the cohesive quality that gluten provides in traditional recipes. It’s especially useful in recipes like gluten-free bread, muffins, and pancakes.

What is Xanthan Gum?

Xanthan gum is a common food additive and thickening agent that is widely used in the food industry, especially in gluten-free recipes and low-fat products. 

It is produced through the fermentation of sugars by the bacterium Xanthomonas campestris. This fermentation process results in a slimy substance that is then dried and ground into a fine powder, creating xanthan gum.

Health Effects of Xanthan Gum

While there is some contention on health effects of xanthan gum and more research is required, currently it appears to have the following effects:

Blood Sugar

Xanthan gum may reduce spikes in blood sugar although results are mixed. It could potentially be useful as an additive to decrease the effect of high-glycemic foods (7).

Weight Management

Because xanthan gum can promote feelings of fullness, it could help you with weight management (7).

Gut Health

Although it was previously thought that xanthan gum passed through the human digestive system with no impact, recent research shows that it does in fact alter our gut microbiota (8). 

Some research shows that it can act as a prebiotic (9) and other that it can be inflammatory (10). Large amounts can cause intestinal upset such as gas and bloating.

Potential Risks of Xanthan Gum

While xanthan gum has been recently evaluated and considered safe for most people (11), it can potentially have negative effects:

Microbiome Changes 

As mentioned above, recent research has found that xanthan gum does change our gut microbiome.

Laxative Effect 

Most of us consume a small amount of xanthan gum in our daily diet so are generally not at risk, but in large doses it can cause a laxative effect and other digestive issues.

Allergic Reactions 

Some research indicates that gums, including xanthan gum, may cause allergic reactions (12).

Culinary Uses of Xanthan Gum

Xanthan gum is an incredibly efficient thickening agent. In recipes, even small amounts can create a smooth, creamy texture in sauces, soups, and gravies. Its thickening power also extends to gluten-free baking, enhancing the texture of your foods.

Xanthan gum has remarkable stabilizing properties, which means it can prevent ingredients from separating or settling. This makes it a popular ingredient in salad dressings, ice cream, and other emulsified products.

In low-fat or reduced-calorie food products, xanthan gum is used to mimic the mouthfeel and texture that fats typically provide. This can make healthier food options more palatable by preserving a desirable texture.

Psyllium Husk vs Xanthan Gum: Properties and Function

Now that we’ve examined the individual characteristics of psyllium husk and xanthan gum, it’s time to compare these two ingredients head-to-head. Depending on your specific needs, one may be more suitable than the other.

Health Considerations

If you’re looking for the health benefits of increased fiber intake, psyllium husk is the clear winner. It can support your digestive health and provide other health benefits. 

However, if you’re only interested in the functional properties of these ingredients in your recipes, both are suitable options.

Texture and Structure

Both psyllium husk and xanthan gum can replace gluten in recipes where you would normally use wheat flour. They contribute to the texture and structure of your recipes, but the results differ slightly. 

Psyllium husk, due to its gel-like consistency, is better at replicating the chewy, bread-like texture of gluten. On the other hand, xanthan gum excels in creating a smoother, silkier texture, which is ideal for things like soups and sauces.

Flavor and Color

Psyllium husk has an earthy somewhat nutty flavor not always to everyone’s liking. In contrast, xanthan gum, while flavorless can sometimes impart a slightly slimy or gummy texture when used in large quantities, which might not be desirable in certain dishes.

Cost and Availability

Psyllium husk is more widely available and often less expensive than xanthan gum. If you’re on a budget, psyllium husk might be the better choice for you.

Substitutes for Psyllium Husk

Substitutes for psyllium husk can vary depending on the specific recipe and the desired outcome. Here are some common alternatives:

Chia Seeds. Chia seeds can be ground and mixed with water to form a gel-like substance similar to psyllium husk gel. The ratio is typically 1 tablespoon of ground chia seeds mixed with 3 tablespoons of water per 1 tablespoon of psyllium husk.

Flax Seeds. You can also grind flax seeds and combine them with water to create a thickening gel. The ratio is similar to that of chia seeds, typically 1 tablespoon of ground flax seeds to 3 tablespoons of water.

Gelatin. Unflavored gelatin can be used to add structure and thickness to recipes like puddings, mousses, and custards. It’s not suitable for vegan or vegetarian diets.

Agar Agar. Agar agar is a plant-based thickener derived from seaweed. It’s commonly used in vegan and vegetarian cooking and can be a suitable replacement for psyllium husk in some recipes.

Substitutes for Xanthan Gum

You have several different options for a xanthan gum substitute:

Guar Gum. Guar gum (extracted from guar beans) is a great substitute for xanthan gum and can be used in a 1-to-1 ratio. It functions similarly in providing thickening and binding properties.

Corn Starch. Corn starch is primarily used as a thickening agent in recipes like sauces and soups. It won’t provide the same binding properties as xanthan gum in gluten-free baking, but it can work in other types of recipes.

Arrowroot Powder. Arrowroot powder can be used as a thickening agent in recipes where you want to maintain a clear, glossy appearance. It’s suitable for gravies, sauces, and puddings.

Tapioca Flour. Tapioca starch or flour can be used in gluten-free baking to improve the texture and create a chewy consistency in recipes. It’s often used together with gluten-free flours.

Potato Starch. Potato starch is another option for improving the texture of gluten-free baked goods. It can be used in combination with other gluten-free flours and starches.

Psyllium Husk. In some cases, you can use psyllium husk in place of xanthan gum, especially in recipes where the binding properties of xanthan gum are not critical.

Egg Whites. In some recipes, egg whites can be used to provide binding and texture-enhancing properties. This is not a vegan-friendly option, but it can work well in non-vegan baking.

When substituting for psyllium husk and xanthan gum, consider the specific properties each ingredient provides in the recipe. The best substitute will depend on the intended outcome and dietary restrictions. 

You can experiment with small batches when trying out substitutions to achieve the desired texture and flavor in your dishes.

Practical Tips for Using Psyllium Husk and Xanthan Gum

Whether you choose psyllium husk or xanthan gum, there are some practical considerations and tips to keep in mind when incorporating these ingredients into your recipes.

Measurement and Usage

For psyllium husk, it’s important to measure carefully, as using too much can lead to a slimy texture. A general guideline is to use about 2.5 teaspoons per cup of flour in your recipe.

For xanthan gum, less is often more. Start with a small amount (usually 1/4 to 1/2 teaspoon per cup of flour) and adjust as needed. It’s easy to overdo it with xanthan gum, which can lead to a gummy texture.


Both psyllium husk and xanthan gum require adequate hydration. Ensure that you mix them with enough liquid to activate their binding and thickening properties.


The best way to find the perfect balance in your recipes is through experimentation. Start with a small batch, adjust the quantity of psyllium husk or xanthan gum, and take notes on the results. This will help you fine-tune your recipes to your taste and texture preferences.
