Egg Protein Powder

Why Should I Add Egg Protein Powder to My Diet?

Egg protein powder is almost always made from egg whites, not the whole egg,

This is because an egg white – the clear liquid that surrounds the yellow yolk of an egg – is made up of 90% water and 10% protein.

Yolks, on the other hand, contain fats and other micronutrients.

It follows that when dehydrated, egg whites contain more protein per gram than yolks, making them a more effective protein supplement.

Whites also have a more neutral flavor profile than yolks, which makes them more compatible with flavors like chocolate and vanilla.

So, when talking about egg protein powder, we are actually talking about egg white protein powder.

Spray drying is the most common way to dry (dehydrate) eggs.

It involves spraying pasteurized eggs into a chamber through which hot air is passing.

This process removes almost all of the moisture, leaving behind a fine powder that is high in protein.

Egg protein powder is arguably the best type of protein powder for several reasons:

1. Eggs are naturally high in protein. A dried egg white is 80% protein, which gives it the most protein per gram than any other whole food. Other dietary protein sources (peas, whey, etc.) have to be mechanically and/or chemically stripped of fats, carbs, etc. before they can be used as a protein supplement.
2. Eggs contain a complete protein. A complete protein contains all of the essential amino acids that your body needs, but cannot produce on its own. Many dietary proteins, including most plant-based proteins, are not complete.
3. Eggs are easy to digest. Unless you have a sensitivity or allergy to eggs, egg protein is the best protein for people with sensitive stomachs. Our customers report fewer digestive issues with our Egg White Protein Powder than with any other type of protein supplement.
4. Eggs have a perfect PDCAAS. Egg protein has a Protein Digestibility Corrected Amino Acid Score (PDCAAS) of 1.0, which is the highest possible score. Only whey protein scores as high. In short, PDCAAS is a method of evaluating the nutritional quality of a dietary protein based on its amino acid profile and how easy it is to break down and absorb.
5. Eggs taste good. Most protein powders have a chalky aftertaste because they are made with protein concentrates or isolates. Egg whites, on the contrary, are almost tasteless, making them a delicious addition to shakes, smoothies, oatmeal, and other recipes.

It is important to note that some eggs sit for days, even weeks before they are 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!

This helps us achieve a best-in-class flavor profile.

What Is the Best Egg Protein Powder?

Not all egg protein powders are created equal.

Unfortunately, many options contain ingredients known to cause painful digestive issues and even long-term gut 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 (North Clin Istanb, 2019).

Over time, this can lead to gut dysbiosis (Microorganisms, 2022), which has been linked to development of many chronic diseases (Sci Rep, 2019).

Keep in mind that your 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 overall 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 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 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 egg whites, which are easier to digest and absorb.
