Low Histamine Protein Powder

Is Protein Powder Good for a Low Histamine Diet?

Histamine is a chemical that acts as a neurotransmitter (chemical messenger).

Among other things, it triggers the release of stomach acid and causes inflammation as part of a local immune response.

Histamine intolerance is a disorder associated with the inability to fully metabolize (break down) histamine, which is both made by the body and taken in from food.

Histamine that is not broken down builds up in the blood, causing symptoms like headaches, nasal congestion, fatigue, hives, and digestive issues.

Common causes of histamine intolerance include:

1. Medications or foods that inhibit the function or production of the gastrointestinal (GI) enzyme diamine oxidase (DAO)
2. Foods that trigger histamine release
3. GI disorders such as inflammatory bowel disease (IBS), leaky gut syndrome, and small intestinal bacterial overgrowth (SIBO).

Note that disorders like IBS can cause inflammation in the gut, which may impair DAO function and production.

Gut inflammation, in turn, can cause excessive histamine production (Eur J Med, 1989).

And excessive histamine production paired with impaired enzyme activity can lead to increased histamine absorption and accumulation in the bloodstream.

In other words, an unhealthy gut could be the main driver of histamine intolerance (Am J Clin Nutr, 2007).

The low histamine diet aims to reduce symptoms of histamine intolerance by avoiding histamine-rich and histamine-releasing foods.

Research shows that reducing histamine-rich foods in the diet dramatically reduces symptoms (Am J Clin Nutr, 2007).

Foods high in histamine include alcohol and other fermented beverages, dairy products, and processed and fried foods.

Examples of histamine-releasing foods include pineapple, shellfish, and tomatoes.

Keep in mind that the low-histamine diet is not a histamine intolerance treatment, but rather a band-aid for symptom relief.

This is why addressing the underlying causes of histamine intolerance, which might a be GI disorder like IBS, leaky gut, or SIBO, is so important.

Moreover, because each of these conditions can be managed through diet, picking the right protein powder can make a huge difference.

What Is the Best Protein Powder for Histamine Intolerance?

Histamine tolerance can vary greatly from person to person, so a protein powder that works for one person might not work for someone else.

That said, there are several guidelines that anyone with histamine intolerance can follow.

Egg white protein, hemp protein, and rice protein are all low in histamine, so it is best to start with one of these protein sources.

🚫 Avoid Food Additives

Then, make sure your protein powder does not contain any food additives, as ingredients like these can be problematic for individuals with histamine intolerance (BMC Med, 2011).

Part of the reason why food additives like emulsifiers and thickeners are so problematic is that they can alter the composition of your gut microbiome.

This can lead to gut dysbiosis, or an imbalance in gut bacteria, which has been linked to the onset and progression of histamine intolerance (North Clin Istanb, 2019).

⚠️ 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.

🚫 Avoid Dairy-Based Proteins

Dairy-based proteins like whey and casein, although not an issue for everyone, can cause digestive issues.

This is usually because they contain lactose, a sugar many individuals with sensitive stomachs cannot fully digest.

But you might be sensitive to dairy-based proteins even if you are not lactose intolerant.

This is particularly true for casein protein, which forms a gel-like substance in your stomach that slows down digestion.

🚫 Avoid Protein Concentrates and Isolates

You might also want to avoid ultra-processed protein concentrates and isolates.

Most protein supplements 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 your gut break them down.

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

Studies show that regularly eating protein concentrates and isolates might disrupt your gut microbiome and cause the formation of toxic byproducts in your gut (Nutrients, 2018; Mol Nutr Food Res, 2024).

You should thus look for protein supplements made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.
