Protein Powder Without Gums

What Are Gums in Protein Powder?

Many protein powders contain gums like guar gum and xanthan gum.

Gums are food additives used to thicken, stabilize, emulsify (mix ingredients that would normally separate, like oil and water), and improve the texture of processed food.

They are typically derived from plants, but they are also ultra-processed.

Common examples include acacia gum, cellulose gum, gellan gum, guar gum, gum arabic, konjac gum, locust bean gum, and xanthan gum.

Note that it is common to see a blend of several gums in protein powder.

Blending gums is often more effective than using just one, since different gums bring different properties to the table.

Are Gums Bad for You?

Gums are generally recognized as safe for human consumption by the U.S. Food and Drug Administration (FDA).

Some people have allergies or sensitivities to them, however.

One of the most commonly reported side effects of gums is digestive discomfort, such as bloating, diarrhea, and stomach pain.

Gums tend to contribute to gastrointestinal (GI) side effects for several reasons:

1. High Fiber Content: Many food additive gums are high in dietary fiber. Fiber, particularly soluble fiber, is fermented by bacteria in your gut. This fermentation might contribute to bloating, gas, and stomach pain, especially for people who are not used to a high-fiber diet.
2. Increased Water Retention: Gums can draw water into your colon, which might lead to soft stools or diarrhea in sensitive individuals.
3. Gut Dysbiosis: Certain gums might alter the composition and function of your gut microbiota, which could impair your ability to digest and absorb food and might contribute to chronic digestive issues (Microorganisms, 2022).
4. Allergies and Sensitivities: Although rare, some people are allergic to certain food gums, such as guar gum. Allergic reactions can vary, but often include gastrointestinal (GI) side effects.

It is important to note that some people are more sensitive to gums than others.

Moreover, the amount of gum consumed, how often it is consumed, and individual differences in gut health can all influence the likelihood and intensity of side effects.

If you experience persistent or severe symptoms after consuming gums, consult a healthcare professional.

What Is the Best Gum-Free Protein Powder?

Obviously, protein powder without gums cannot contain gums.

But if you are looking to avoid gums, then you might also want to avoid gum-like thickeners such as acacia fiber, carrageenan, and inulin.

In fact, if gums upset your stomach or conflict with your dietary preferences, then you might want to steer clear of food additives altogether.

🚫 Avoid Food Additives

Regularly consuming emulsifiers, thickeners, artificial sweeteners, and other ultra-processed additives might alter the makeup and function of your gut microbiome – the community of bacteria and microbes that live in your digestive tract (North Clin Istanb, 2020).

These shifts, known as gut dysbiosis, have been shown to contribute to a range of chronic diseases, including obesity, diabetes, and certain cancers (J Exp Med, 2019).

Gut dysbiosis is so problematic because it can contribute to a cascade of issues, including intestinal permeability (a leaky gut lining), systemic inflammation, poor nutrient absorption (J Exp Med, 2019).

It is important to note that much of this research is still emerging, so more studies are needed to clarify these relationships.

That said, the preliminary findings suggest that because protein shakes and powders are something you consume regularly, if not every day, the cumulative effects of small amounts of potentially harmful ingredients is worth taking seriously.

⚠️ Here is a list of the most common food additives in protein shakes and powders:

• acacia fiber
• acacia gum
• acesulfame potassium
• artificial flavors
• ascorbic acid
• aspartame
• calcium carbonate
• carrageenan
• cellulose gum
• dextrin
• dicalcium phosphate
• dipotassium phosphate
• erythritol
• gellan gum
• guar gum
• gum arabic
• inulin
• locust bean gum
• maltitol
• maltodextrin
• mono- and diglycerides
• ‘natural’ flavors
• rice bran extract
• rice dextrin
• rice hulls
• rosemary extract
• silica
• silicon dioxide
• sodium alginate
• soluble corn fiber
• sorbitol
• soy lecithin
• sucralose
• sunflower lecithin
• tocopherols
• tricalcium phosphate
• xanthan gum
• xylitol
• zinc oxide

As a rule of thumb, if you cannot find it in nature or make it at home, it is probably a food additive.

🚫 Avoid Protein Concentrates and Isolates

I also recommend avoiding protein concentrates and isolates.

Most protein powders are made from one or both of these ultra-processed protein sources, which have been mechanically and/or chemically stripped of everything but the protein.

This includes the enzymes, fiber, and other natural digestive aids that help you break them down.

You therefore might not digest them in the same way that you do whole foods, which could affect your gut health.

For example, one study shows that regularly consuming protein concentrates and isolates might disrupt your gut microbiome (Nutrients, 2018).

Another study shows that it could cause the formation of toxic byproducts in your gut (Mol Nutr Food Res, 2024).

Although further research is needed, you can play it safe by choosing protein powders made from minimally-processed protein sources like egg whites and almonds.

Our customers find them to be more gut-friendly.
