Gums in Protein Powder

What Are Gums?

If you pay attention to what is in protein powder, you will have noticed that there are usually gums on the ingredient list.

And if you are wondering what gums are doing in your protein supplement, you have come to the right place.

Gums are common food additives used to thicken, stabilize, emulsify, and improve the texture of processed foods.

They are typically derived from plants, but are so processed they cannot really be considered natural.

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

The benefits of adding gums to protein powder include:

• Improved Texture/Mouthfeel: Most protein powders are chalky or gritty; gums help to mask these textures/aftertastes.
• Better Mixability: Gums act as dispersing agents, helping protein powder to dissolve without clumps.
• Greater Stability: Gums prevent protein powder from separating or settling in liquid.
• Lower Costs: Gums are inexpensive, allowing manufacturers to improve product quality without significantly increasing their costs.

Despite these benefits, however, gums are not something you want in your diet.

Are Gums Bad for You?

Although they are generally considered safe for human consumption by the U.S. Food and Drug Administration (FDA), gums are notorious for causing painful side effects.

One of the most common side effects caused by gums is digestive issues like bloating, diarrhea, and stomach pain.

Gums tend to cause digestive issues for several reasons, including:

• High Fiber Content: Many gums are high in dietary fiber. Fiber, particularly insoluble fiber, is fermented by bacteria in your gut, which can cause bloating, flatulence, and stomach pain, especially for those not used to a high-fiber diet.
• Increased Water Retention: Gums can draw water into your colon, leading to softer stools and diarrhea in sensitive individuals.
  Allergies and Sensitivities: Although rare, some people may be allergic to specific gums, such as guar gum. Allergic reactions can vary in severity and might include gastrointestinal (GI) side effects.

Regularly consuming certain gums can also alter the composition and function of your gut microbiome (Curr Dev Nutr, 2022).

These shifts, known as gut dysbiosis, have been linked to the development of chronic digestion problems like irritable bowel syndrome (IBS) (JGH Open, 2021).

It is important to note the amount of gum consumed, the frequency of consumption, and individual differences in gut health can all influence the occurrence and intensity of side effects.

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

What Is the Best Protein Powder Without Gums?

It goes without saying that a gum-free protein powder cannot contain guar gum, xanthan gum, etc.

But did you know that acacia fiber, carrageenan, and inulin are basically the same thing?

These gum-like additives are also notorious for causing digestive issues and long-term gut health problems.

So if you have a sensitive stomach, I would recommend avoiding food additives altogether.

⚠️ Here is a list of the most common food additives in protein supplements:

• 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.
