The main difference between a Collagen Protein and a Whey Protein is the amino acids profile of each. Collagen protein contains eight essential amino acids while whey protein has nine essential amino acids.
But, the difference does not end there. There are other distinct differences between the two. It is important to know the differences to help you decide which one you should use as a supplement to achieve your healthy lifestyle goals.
If you want to know more about collagen protein and whey protein differences, we have prepared a list below of the main difference between the two.
What is Whey Protein?
Before we discuss the differences between collagen protein and whey protein, it is best if we first get details about the two. Let’s start with Whey Protein.
Whey Protein is one of the two proteins found in milk, the other being casein. Whey protein is made up of globular proteins and is water-soluble. It is also a complete protein as it contains all 9 essential amino acids.
Whey Protein is mainly used as a sports supplement because it is quickly absorbed by the body and helps to increase muscle.
What is Collagen Protein?
Collagen Protein is a protein that is found in the connective tissues of animals. It is made up of long chains of amino acids and is insoluble in water.
Collagen Protein is mainly used as a supplement to improve body composition such as joint health, skin health, and hair health.
What are the differences between Collagen Protein and Whey Protein?
Now that we have a general understanding of what collagen protein and whey protein are, let’s take a look at the main differences between the two.
Collagen Protein is derived from bovine hide and skin, bone, joint material, and certain organs of animals, fishes, and fowl while whey protein is from milk.
Manufacturing Process for Supplements
The manufacturing process of these two vital proteins differs as follows:
Collagen peptides are manufactured through a process of hydrolysis where enzymes are used to break down the collagen into smaller pieces. These peptides are then packed into powders, pills, or drinks.
Whey protein is made through a process of ultrafiltration where the whey is filtered from the casein. Casein is the main protein in milk and cheese (in coagulated form).
Amino Acid Profiles
As we mentioned earlier, for these vital proteins the amino acids profile is one of the main differences between collagen protein and whey protein.
Whey protein is riched in branched-chain amino acids such as valine, leucine, and isoleucine used for muscle protein synthesis.
Collagen Protein, a structural protein, on the other hand, is made up of amino acids like proline, hydroxyproline, and lysine that are mainly used to create structure and support connective tissue, skin, hair, and nails to stay as healthy as possible.
Rate of Absorption
Whey protein takes about an hour and a half to be digested and only about eight to ten grams can be digested per hour. Though, whey protein with digestive enzymes, amino acid absorption can be boosted up to 127%.
Collagen when ingested can only be absorbed by the body at around 49.6% and 57.8% based on a study by ACS Publications. But when collagen is hydrolyzed, this is when collagen is broken down into smaller pieces, the absorption rate of main amino acids such as glycine and proline can be as high as 90% within 6 hours.
In general, whey protein is absorbed faster than collagen protein.
Effect on Skeletal Health
Whey protein supplement neither improves nor adversely affects the skeletal system while hydrolyzed collagen peptides can support bone health.
Collagen peptides stimulate osteoblasts, which are cells that create new bone tissue while also inhibiting osteoclastogenesis. Osteoclastogenesis is the process where old bone tissues are broken down.
A study done on rats showed that when given collagen supplementation, there was an increase in bone mineral density and bone growth.
Another study showed that when postmenopausal women were given a collagen supplement for 12 months, there was an improvement in their trabecular bone score, which is a measure of the microarchitecture of bones.
Whey protein with its key amino acids content supports muscle protein synthesis faster than collagen protein. Aside from the improvement in lean muscle growth, whey protein also aids in faster metabolism and post-workout recovery.
Collagen protein also helps in building lean muscle mass and easing joint pain.
The majority of the time whey protein has a chalky taste while collagen powder doesn’t have much flavor. You can mix both with water or milk but many people tend to add it to their smoothies, oats, or Greek yogurt to help with the taste.
Which is Better Collagen or Whey Protein?
Deciding which is better between which protein is better depends on your fitness goals.
If you’re aiming to improve your skeletal health, then collagen peptides are your best bet. If you want to enhance muscle synthesis and growth, whey protein is what you need.
For people who want to improve their overall health, both are excellent options as they provide different benefits that can be vital.
