Egg White Protein Powder

What Is Egg White Protein Powder?

The egg white, also known as the albumen, is the clear liquid that surrounds the yellow yolk of an egg.

It constitutes two thirds of the egg by weight and is made up of 90% water and 10% protein.

Egg white protein powder, also known as albumen protein powder, is a protein supplement made from pasteurized, dried egg whites.

Spray drying is the most common way to dry (dehydrate) egg whites and involves blowing liquid egg whites into a chamber through which hot air is passing.

This process removes almost all of the moisture, leaving behind a fine white powder that is roughly 80% protein.

It is worth noting that dried egg whites have the most protein, by weight, of any whole food protein source.

For this reason, they require less processing to become protein powder than any other type of protein.

Why Should I Use Egg White Protein Powder?

There are many reasons why adding egg white powder protein to your diet is arguably the best way to supplement your protein intake, including:

• Egg whites contain a complete protein. The protein found in egg whites is a complete protein, meaning it contains all nine essential amino acids that the body needs but cannot produce on its own. Many protein sources, including most plant-based protein sources, are not complete.
• Egg whites are highly digestible. Egg whites, along with whey, have the highest protein digestibility-corrected amino acid score (PDCAAS) of any protein (J Nutr, 2000), meaning they are easily absorbed and used by the body.
• Egg whites are gut-friendly. Egg whites cause fewer digestive issues than any other protein source. They are low in fiber, low FODMAP, alkaline (help maintain healthy pH levels in your gut), and even bioactive (promote the growth of healthy gut bacteria) (J Agric Food Chem, 2023).
• Pro: Egg whites taste good. Unlike most protein powders, Egg White Protein Powder does not have a chalky aftertaste. This is primarily because egg whites, unlike protein concentrates and isolates, have not been mechanically and/or chemically stripped of everything but the protein.

It is important to note that some eggs sit for days, sometimes weeks before being processed.

As a result, they begin to decay and release a chemical called hydrogen sulfide, which has a potent sulfur odor.

This is why we break our eggs less than twenty-four hours from when they are laid.

The result is a flavor without the “eggy” notes typical of other eggs.

What Is the Best Egg White Protein Powder?

Not all egg white protein powders are created equal.

Unfortunately, many egg white protein powders are made with ingredients known to cause painful side effects and long term health problems.

Among these ingredients are food additives and protein concentrates and isolates.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners, and other additives can not only upset your stomach, but also alter the composition of your gut microbiome (the collection of microorganisms living in your gut) (North Clin Istanb, 2019).

This can lead to gut dysbiosis, or an imbalance in your gut microbiota (Microorganisms, 2022), which contributes to the development of several chronic diseases, including inflammatory bowel disease, metabolic syndrome, and obesity (Microb Ecol Health Dis, 2015).

Keep in mind that the gut microbiome affects various physiological processes, including immune function and inflammation, so when the balance of bacteria therein is disrupted, it can have a huge impact on your digestive health.

⚠️ 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 Protein Concentrates and Isolates

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

Some egg white-based 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 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 (Nutrients, 2018) and cause the formation of toxic byproducts in your gut (Mol Nutr Food Res, 2024).

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