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 roughly 90% water and 10% protein.

It follows that when dehydrated, egg whites contain more protein per gram than yolks, which are higher in fats and micronutrients.

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

So, when we talk about egg protein powder, we are really 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 widely considered to be one of the best types of protein powder for several reasons:

1. Eggs are naturally high in protein. A dried egg white is about 80% protein, which gives it one of the highest amounts of protein per gram of any whole food. Other protein sources (peas, whey, etc.) have to be mechanically and/or chemically stripped of fats, carbohydrates, and other components before they can be used as a protein shake or powder.
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 protein sources, 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 might be a good option for people with sensitive stomachs. Our customers report fewer digestive issues with our Egg White Protein Powder than with any other type of protein shake or powder.
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 a few proteins, such as whey, score as high. PDCAAS is a method of evaluating the nutritional quality of a protein based on its amino acid profile and how easy it is to break down and absorb.
5. Eggs taste good. Many protein powders have a chalky aftertaste because they are made with protein concentrates or isolates. Egg whites, on the other hand, are almost tasteless, which makes 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 strong 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.

What Is the Best Egg Protein Powder?

The best egg protein powder is made without artificial or ultra-processed food additives.

Regularly consuming ingredients like these can not only upset your stomach, but also contribute to long-term health problems.

🚫 Avoid Food Additives

Emulsifiers, thickeners, artificial sweeteners and other additives might alter the composition of your gut microbiome (North Clin Istanb, 2020).

These shifts, known as gut dysbiosis, might 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

You might also want to avoid ultra-processed egg white protein concentrates/isolates.

Some egg protein shakes and powders have undergone additional mechanical and/or chemical processing to increase the protein percentage.

As a result, they look less like real food, which might affect digestion.

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.
