What is the Difference Between Collagen Protein and Pea Protein?


Nowadays, getting protein from different sources is often recommended to ensure one gets all the essential and non-essential amino acids the body needs. One protein source that is slowly gaining popularity is pea protein. But what is pea protein, and how does it compare to one of the most popular sources, collagen? Keep on reading to learn more.

What is Pea Protein?

Pea protein comes from the extract of split peas; during the process, the fiber and starches are extracted so the only thing left is the protein. Pea protein is free of the common allergens, such as dairy and gluten, making it easy to digest and safe for most people with allergies. It’s also a great alternative for vegetarians and those opting for plant-based diets.

Peas have protein, we know that much. However, peas are not considered a complete protein source. Complete proteins are those that contain the nine essential amino acids, which are the amino acids that the body cannot produce naturally and have to be obtained through our diets. Although pea protein contains all essential amino acids, it’s not a complete protein source because of its low content of methionine. Not only do complete protein sources have to contain all essential amino acids, but they also need to have the right concentration. So, this little detail is actually a big deal when it comes to choosing a protein supplement.

In regard to the benefits of pea protein, there are numerous. Since pea protein is free of the common allergens, it does not cause bloating and is recommended for individuals with digestive issues. This is primarily why many individuals opt for pea protein.

Being a legume, peas are generally hard to digest. Nonetheless, thanks to the process of extraction, pea protein is very easy to digest (although it doesn’t absorb as rapidly as other sources of protein).

Pea protein is also high in iron; however, it is not as biologically available as other protein sources. In order to maximize the absorption of iron, it must be complemented with a source of Vitamin C.

Additionally, the protein in peas (in general) has been shown to help lower cholesterol and blood pressure. It’s also a low-calorie food without unnecessary and saturated fats found in other sources of protein.

The main drawback of pea protein, as previously mentioned, is its methionine content. The good thing about it is that if you eat a complete and varied diet, you are likely getting your intake of methionine from other food sources, such as eggs, fish, beef, and nuts. However, if pea is your only protein source, you might be in trouble. Pea protein also has a different texture and flavor than what one is typically accustomed to; nonetheless, it’s always up to individual taste.

What is Collagen Protein?

Collagen is the most abundant protein in the human body; it is found in our bones, skin, ligaments, tendons, tissues, and muscles. Collagen is what holds everything together – think of it as the glue holding everything in your body in place.

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.

Although our bodies naturally produce collagen, production starts to decline after our twenties. This is when we start to experience fine lines and wrinkles, dry skin, and achy joints. After this point, it’s essential to include collagen in our diet to keep our skin looking youthful and our joints pain free. Imagine that something that we have been producing is now decreasing, its only right to try to replenish as much as we can.

Collagen has many notable benefits. Collagen is key in producing hydrated, elastic, and moisturized skin and its consumption is beneficial for the reduction of fine lines and wrinkles. Collagen promotes strong and healthy hair and can also reduce the frequency of brittle nails.

Collagen can also help improve joint health. Studies show that collagen is crucial to reduce swollen joints and joint tenderness. Collagen helps maintain the integrity of your cartilage, which is the rubber-like tissue that protects your joints. And, since collagen is a key structural component of the cartilage, maintaining sufficient levels if essential for keeping joints healthy.

Collagen can also help prevent bone loss. As we age, our bone mass deteriorates just as our collagen does too. 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. Collagen is also beneficial for 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.

What Should I Choose: Collagen Protein or Pea Protein?

There isn’t a “one size fits all” when it comes to protein. Luckily, there are so many options in the market that your best bet will be to try them out and choose the one that is a good fit with your body and lifestyle. Do you want a plant-based protein, or an animal-based protein? Are you looking to control your weight or to support your skin and joints?
