What is the Difference Between Collagen Protein and Egg Protein?

Obtaining protein supplementation through eggs is probably one of the easiest and most affordable ways to get your daily protein requirements. That’s why individuals opt to eat eggs for breakfast, as it’s a great way to get enough protein and stay full throughout the morning.

One large egg provides approximately 6 grams of protein, most of which is present in the egg white, 5 grams of fat, and 72 calories. They are extremely nutritious, as they are full of Vitamin B12, Vitamin B2, Vitamin A, and Vitamin B5. They also contain small amounts of essential minerals, such as calcium, iron, potassium, and zinc.

Lately there has been a resurgence of egg protein supplements in the market, mostly available in powder form. This seems to be an effective way of obtaining egg quality protein in a convenient and effective presentation.

Below we’ve detailed a few quick characteristics of egg protein, followed by our protein of choice, collagen. Explaining both can help you determine which source is right for you.

What are Some of the Benefits of Egg Protein?

One of the major benefits of eggs are its high protein concentration. Like all animal sources, eggs are considered complete proteins. This means that egg protein contains all essential and non-essential amino acids. Although there are other sources that may contain more protein per serving, eggs contain high quality protein, with the right concentration of amino acids, that allows it to really stand out.

Eggs are full of essential nutrients. They contain choline, a nutrient required for the body to function properly. Choline plays a role in cellular function and it’s important for liver and heart health, as well as brain development. Choline is especially important during pregnancy as it helps support healthy brain development in the baby. As previously mentioned, eggs are loaded with vitamins, minerals, and good fats. When combined with a high protein content, all of these properties make eggs a great nutritional food.

Eggs are also good for weight control as they are highly satiating. This low-calorie protein source can help make you feel fuller for longer periods of time. Eggs can help reduce variations in glucose and insulin levels, also benefiting weight management.

Additionally, eggs contain two antioxidants (lutein and zeaxanthin) that help protect the eyes. These antioxidants accumulate in the retina where they are able to protect the eyes from sunlight. They can also help reduce the risk of cataracts.

Does Egg Protein Have Any Drawbacks? 

Scientist have long debated the health benefits of eggs, and their research still continues. Many individuals are cautious when eating eggs as they contain very high levels of cholesterol. This is certainly true, as one large egg can contain about 200mg of cholesterol. Our liver naturally produces all the cholesterol our body needs; this is called blood cholesterol. We can also get cholesterol from foods; this is called dietary cholesterol.  

Because of the high percentage of cholesterol found in eggs, there have been associations between eggs and the risk of heart disease. Some studies have shown that egg consumption is linked to high blood cholesterol levels, leading to higher risk of heart problems and premature death.

But the cholesterol found in eggs doesn’t necessarily raise cholesterol levels in the blood. That’s because dietary cholesterol doesn’t have much impact on blood cholesterol levels. Saturated fat and trans-fat, however, can raise cholesterol levels in the blood. So, if you’re eating eggs, notice what you’re eating them with. Avoid bacon, butter, and cheese, and pair them with healthier options like veggies or whole-grain toasts.

Egg Protein Supplements

Many individuals are opting for egg protein supplements to meet their daily protein requirements. They are generally high in quality protein and contain no fat. Most egg protein supplements are made from egg whites rather than whole eggs, so they are lacking in some nutrients.

Egg protein supplements usually come in powder form, so you have to blend it with liquids to consume. Egg protein supplements available in liquid forms, although carrying a high amount of protein, require you to consume over 8 ounces to meet your needs. They can also carry an “egg” taste that lingers even after it is blended. Luckily, there are flavored and unflavored options for you to choose from.

Collagen Protein

Now that we’ve gone through the basics of egg protein, let’s get into another source of animal protein: collagen.

Collagen is the most abundant protein in our body; it actually makes up one third of all that protein. Our body naturally produces collagen and it is found basically everywhere, in our skin, hair, nails, tendons, joints, muscles, and bones.

Collagen has been known as the “glue that holds the body together” because it provides structure to our bones, skin, and connective tissue. It’s responsible for our skin elasticity, the strength of our hair and nails, and even the flexibility of our joints. Since collagen is a protein, it helps improve our muscle mass and prevent bone loss. Collagen is also linked to our gut and cardiovascular health, as well as mood and anxiety.

Collagen in our body starts to decline after our twenties. At this point, we may start to notice fine lines, wrinkles, dry skin, and loss of joint range of motion. Collagen production can also be affected by sun exposure, smoking, and inadequate diets. What we can do to prevent as much as possible the decline of collagen in our bodies is to encourage its production by adding supplementation.

Here are a couple of reasons to try adding collagen to your diet:

Joint health: When we start to lose collagen, our joints start to feel tender and achy. Adding collagen to our diet can play a role in reducing swollen joints and tenderness by maintaining the integrity of your cartilage, which is what cushions the joints.
Recovery: Whether you’re recovering from surgery or from a workout, collagen can help speed up the recovery process by providing the necessary amino acids.

Healthy skin, hair, and nails: When collagen declines, we lose the strength, moisture and elasticity of our skin, hair, and nails. Adding collagen can help decrease the creation of wrinkles, as well as promote strong and healthy hair and nails.

Bone mass: Bone mass reduction may lead to conditions such as osteoporosis, which is characterized by low bone density and linked with a higher risk of bone fractures. Consuming collagen supplements may help reduce the risk of bone disorders and may help lower levels of proteins in the blood that stimulate bone breakdown.

Digestion and gut health: Collagen contains Glycine, Glutamine, and Proline, amino acids that help with gut and digestion. This combination can help the stomach absorb nutrients, prevent inflammation in the intestinal lining, increase metabolism, and support digestive health.

Cardiovascular health: Proline also helps repair tissue in your arteries and regulate blood pressure.

Muscle growth: Muscle growth is associated with protein, but we rarely add collagen to the equation. Remember that collagen is a protein, so it contains the amino acids needed to fortify and grow your muscles.

Most collagen in supplements come from the bones, skin, and connective tissue of animals, including pigs, fish, and cattle. Plants do not produce collagen; you can only obtain it from animal sources. Aside from supplements, collagen can also be obtained from foods, specifically from bone broth.

How Does Egg Protein Compare to Collagen Protein?

Both egg and collagen protein are good, high quality protein sources that can be added to most diets. Egg protein, however, should be avoided by individuals who are prone to high cholesterol or cardiovascular conditions, as the addition of eggs can be damaging to their health. Individuals who are allergic to eggs should certainly avoid this type of protein. Since egg protein is relatively new in the market, studies are lacking on its possible side effects, benefits and drawbacks.

It’s important to note that collagen is not a complete protein source because it’s lacking one essential amino acid. Our product, Proteinex, is a liquid collagen supplement that contains all essential and non-essential amino acids – the amino acid that is lacking in collagen protein has been added, to make Proteinex a complete protein source.

Depending on your protein needs, one of these sources may be a better fit for you. Whether for health reasons, medical conditions, or fitness goals, study the sources and determine which one suits your lifestyle. A combination of both might also be a good idea, although always make sure of the concentrations of proteins, fats, and carbs to make sure that you are supplementing correctly and not exceeding the daily required amounts.


Our liquid protein, Proteinex, is a great alternative for those who want a high concentration of protein in a small serving size. Just two tablespoons provide 18 grams of hydrolyzed protein, free of fats, carbs, and sugar. This highly digestible protein source is ready to drink, no mixing required, and requires no preparation. The liquid presentation can also be added to water or other beverages depending on your taste. One of the good things about Proteinex, or collagen protein in general, is that its free of the most common allergens, such as dairy, gluten, egg, shellfish, and soy.

Many of our customers love Proteinex because it’s rapidly absorbed by the body. This means that you can avoid the bloating feeling that’s caused by most protein supplements, leading to less stomach distress or digestive problems. Additionally, with just two tablespoons you can easily meet your protein needs. If you’re looking to add protein supplementation to your diet, look no further. Click the product below to learn more!
