Collagen protein powder is a popular supplement that people use in many different ways. While it’s considered a protein powder just like whey or soy, it functions differently in the body and has different benefits.
It’s been available for years in the form of gelatine, but more recently collagen protein has exploded in popularity. Here’s why collagen protein can be so useful.

What is Collagen Protein?
Collagen protein is the most abundant protein in the human body, making up almost a third of the body’s total protein content.
Our bodies can make collagen on their own, but getting extra through your diet or supplements can provide additional benefits. The most common form of collagen supplement is hydrolysed collagen.
How does collagen protein work?
Collagen actually works quite differently from whey or soy protein supplements. Because our body makes its own collagen, it maintains the balance of collagen being broken down and produced based on the presence of the amino acids, or building blocks, in our system.
When collagen is broken down into its building blocks, the body thinks it needs to produce more. Taking hydrolysed collagen as a supplement makes the body think it’s detecting a break down in collagen levels, and causes it to produce even more.2
What does collagen do?
There are actually more than 10 different forms of collagen proteins, but there are four primary types that play key roles in the body.
Type 1 Collagen
This type makes up most of the collagen in the human body, up to 90%, and is the dense type that provides structure to several body components — like teeth, skin, bone, and cartilage.3
Type 2 Collagen
This type of collagen is more elastic and stretchy, less densely packed than type 1, and is primarily found providing cushioning to your joints.3
Type 3 Collagen
Type 3 collagen’s role is to provide structure to your arteries, organs, and muscles. It’s often combined with Type 1 to enhance skin, hair, and nail health.3
Type 4 Collagen
Type 4 collagen is crucial in skin health and helps to provide a filter between the outside environment and your body.3
Sources of collagen
Because collagen is a naturally occurring protein, most supplements are sourced from animal sources — like cows, pigs, and fish. The supplements can come in different forms but hydrolysed (or partially broken down) collagen seems to have the greatest benefit. You may be familiar with gelatine, which is a less processed form of collagen that’s often used in cooking.
Collagen Powder / Collagen Protein
Collagen protein powder is likely the most widely available form of collagen on the market. It’s typically found in the hydrolysed — or broken down — form, making it the easiest for the body to absorb.9 It shows the most success in research studies and it mixes easily into beverages and can be added to your post workout shake or taken on its own. Research supports that it improves muscle health like other protein sources.11

Beverages
Collagen “shots”, or drinks, are another popular form of supplement. They have the collagen already dissolved in a liquid that you can easily take on its own. The benefits of these supplements depend on the types of collagen included — as noted above, types 1-4 are the most beneficial. However, they can be pricey and often require refrigeration, making them more difficult to use on the go.
Bone Broth
Bone broths are another popular way people get collagen in their diets. Although not a true supplement since these are more of a soup, they naturally contain high levels of collagen. They have become popular in recent years and can be found in many grocery stores. They are also easy to make home.
Topical Cream
Topical creams designed to help improve skin elasticity and have anti-aging effects are widely available. The thought is that these work by increasing the amount of collagen in the skin where they’re applied. Research shows that consistent use of topical collagen products can increase hydrating and elasticity of skin over time.12
Collagen Supplement | Benefit | Considerations |
Powder | Easy to add to drinks and foods, easily digested, often targets muscle growth | May not be suitable for vegans/vegetarians, note which types are included |
Beverages | Convenient | Can be expensive, note which types of collagen are included |
Bone Broth | Natural source of collagen, widely available, can make at home | Can be high in salt, hard to know collagen levels |
Topical Cream | Increases skin hydration and elasticity | Hard to know collagen content in products, must be used consistently |
What are the benefits of collagen protein?
Collagen plays several key roles in the body. While you probably know that some of its benefits are similar to other sources of protein, collagen protein has some unique benefits that might make it worth trying.
1. Collagen helps muscle growth and repair
When combined with a healthy diet and good exercise routine, collagen can help build and strengthen muscle.
These benefits can be useful for bodybuilders and the non-athlete alike, to combat the impact of aging on our body’s muscles.
By boosting lean mass and decreasing fat mass, you may also see weight loss as a benefit of collagen protein powder. Having greater muscle mass can boost your metabolism in the long term, and consuming a diet high in protein helps to keep you feeling satisfied longer — decreasing your overall calorie intake while preserving lean mass.
This is how you train harder for longer.

2. Collagen may support weight-loss
Some researches have supported the idea that collagen may support weight-loss and speed-up metabolism. The purified, high-protein content of hydrolysed collagen is known to be an effective, natural appetite suppressant, in which many clinical studies have proven the satiating effect to promote weight-loss.
3. Collagen promotes healthy skin, hair and nails
Collagen has long been used by women as a dietary supplement for healthier skin, hair, and nails. Gelatine, a culinary form of collagen used in cooking, has been popular for years as a thickening agent for liquid ingredients.
While you might see collagen as an ingredient in topical creams for the skin touting anti-aging benefits, research has proven a reduction in wrinkles when taking it as a consistent dietary supplement.5
This type of discovery suggests there are benefits of consuming extra collagen in our diet even though the body can make it on its own.

4. Collagen promotes healthy joints
Not only is joint pain common during the aging process, but it can also be a problem for athletes that impacts their performance. When our connective tissue starts to break down from aging, disease, or injury, inadequate levels of collagen can commonly be the problem.6
Because collagen is key for strong healthy joints, taking a collagen supplement to increase the body’s creation of new collagen can help to maximize production. Research shows the greatest benefit when collagen is taking about one hour prior to exercise.6

5. Collagen could play a role in digestive health
Due to its structural nature, collagen actually plays a role in keeping our digestive systems healthy. The stomach and intestines work like large muscles pushing food through the digestive system and extracting the nutrients we need. Research into this area of collagen supplementation is still relatively new though.7

6. Collagen may help sleep
A decent sleeping pattern can do miraculous things for our body. Besides the obvious factor of making you feel less tired and lethargic during the day, more sleep can increase the quality of your health, improve your everyday moodand yoursex life. Plus, not getting enough sleep could be the reason you’re not losing weight too…
Collagen Side Effects
Because collagen is a protein that occurs in our bodies and is easily digested, the risk of side effects is limited like any other type of protein supplement. A review in the International Journal of Sport Nutrition and Exercise rated it as low risk for any side effects.8
Although collagen supplements are typically sourced from cow, pig, or fish sources, the processing typically limits the concerns about any type of allergens. However, vegetarians or vegans may want to check the labels on their supplements to learn more about the source of collagen.
Collagen Foods | How can I get more collagen in my diet?
The primary sources of dietary collagen come from animal products — and the parts that contain the most collagen, like skin and bones.
You can consume collagen from chicken or turkey with skin on, or canned fish with bones (like salmon or sardines).
The gelatine form is found in gelatine moulded foods and desserts. Bone broth is a very rich source of collagen and is popular in many grocery markets.

The best way to take collagen protein
The two main ways to get collagen protein are from powdered collagen or gelatine. Collagen protein powder in peptide or hydrolysed form does not thicken liquids like gelatine does, so it can be used in many ways.
Some people mix it into coffee or tea, others use it in a post workout recovery smoothie or shake. Although it’s available in pill form and beverages, most of the research has been done on the powdered form.
