You’ve probably seen guar gum on the ingredient label of foods and drinks before. What is guar gum, and what does it do?
Guar gum is used as a food additive and acts as a thickener, stabilizer, and binder in processed foods and drinks. Due to its high fiber content, guar gum can also be taken as a dietary supplement.
We’ll answer other questions like how guar gum is made, if it’s good for you, and more below!

What is guar gum?
Guar gum is a powder that forms a gel when combined with liquid, making it a popular food additive for thickening, stabilizing, and binding foods. It can help prevent ingredients from separating, similar to carrageenan.
Guar gum is made by grinding the outer layer of the seeds of the guar bean (Cyamopsis tetragonolobus), a plant that has been primarily grown in India and Pakistan.
Guar gum is 100% natural and is “Generally Recognized as Safe” (GRAS) by the United States Food and Drug Administration.
What is guar gum used for?
Guar gum is used primarily as a thickener and can be found in:
- Beverages (including plant-based milk)
- Processed cheeses
- Dairy products (including yogurt)
- Processed meat products
- Bakery products
- Salad dressings and sauces
Guar gum is also found in non-food products like cosmetics, certain medications, and even paper products.
Guar gum as a supplement
Guar gum can also be taken as a dietary supplement because it’s very high in soluble fiber. Soluble fiber absorbs water and can help thicken loose stools in people with diarrhea, help promote healthy blood sugar metabolism, support healthy cholesterol levels, and help prevent constipation.
When taken as a supplement, a typical dose of guar gum is 5-7 grams three times per day, but it varies depending on its intended use (cholesterol, constipation, etc).
Is guar gum good for you?
Guar gum is generally considered safe to consume, and it might even be beneficial to your health in some ways.
Like many things, some studies suggest guar gum is healthy, and some that suggest it might have negative attributes. For instance, one study concluded that guar gum increases the healthy bacteria in the gut, while another study concluded that it negatively impacts the healthy bacteria in the gut and causes inflammation.
What if you eat too much guar gum?
What happens if you consume too much guar gum in supplement form? You might experience side effects like increased gas and loose stools.
One of the potential dangers of guar gum is consuming large amounts without drinking enough water. Doing so could lead to a dangerous bowel blockage or blockage of your esophagus, which is why following the dosing recommendations for guar gum supplements is essential.
If you’re consuming guar gum as a food additive, the amounts are likely much lower than the amounts you’d consume as a dietary supplement, which reduces the likelihood of causing any adverse effects.
Is guar gum suitable for special diets?
Guar gum is vegan, gluten-free, and suitable for special diets like keto and Whole30. However, it is not Paleo-friendly because it’s made from a legume, which is a Paleo no-no.
FAQs:
Guar gum is safe when taken with enough water (at least eight ounces, which helps reduce the risk of choking and bowel blockage) and when doses don’t exceed the recommended amount. Always refer to the dosing instructions on dietary supplements, including guar gum, for safety.
Is guar gum the same as carrageenan?
Guar gum and carrageenan are both stabilizing agents in food, but they are different. Guar gum is made from seeds of a legume while carrageenan is made from red seaweed.
Guar gum is a 100% natural ingredient made from seeds of the Cyamopsis tetragonoloba plant (guar bean).
