Introduction
You finish a tough training session, reach for your shaker bottle, and check the label on your collagen. It says 18 grams of protein per serving. Naturally, you add that to your daily macro count. But then you hear someone at the gym claim that collagen "doesn't count" because it’s an incomplete protein. It’s a confusing spot to be in when you are trying to dial in your nutrition and recovery.
At BUBS Naturals, we believe in keeping things simple and transparent. You deserve to know exactly what you are putting in your body and how it moves the needle for your health. Whether you are tracking macros for muscle gain, fat loss, or general longevity, understanding how different protein sources work is a requirement for success. You can learn more about the brand behind the tubs on our story page.
This guide will break down the science of amino acids, explain why the nutrition label might look a little strange, and give you a definitive answer on how to track collagen in your daily diet. We will look at the specific role of collagen peptides and how they fit into a high-performance lifestyle.
Quick Answer: Yes, you can count collagen peptides toward your total daily protein intake, but they should not be your only source. While collagen provides roughly 18 grams of protein per scoop, it is an "incomplete" protein because it lacks the essential amino acid tryptophan. Most nutrition experts suggest that collagen can safely make up about 30% to 36% of your total daily protein without negatively impacting your amino acid balance.
Understanding the "Incomplete" Protein Label
To understand why people debate whether collagen "counts," we have to look at the building blocks of protein: amino acids. Your body uses 20 different amino acids to function. Think of these as the alphabet. To "write" the various proteins your body needs—like muscle tissue, enzymes, or hormones—you need the right letters.
Of those 20 amino acids, nine are considered "essential." This means your body cannot make them on its own. You must get them from your food or supplements. A "complete" protein source, like beef, eggs, or whey, contains all nine of these essential amino acids in adequate amounts.
Collagen is different. It is an animal-based protein, usually sourced from bovine hides or fish scales, but it is not a complete protein. It is naturally very high in three specific amino acids: glycine, proline, and hydroxyproline. However, it is missing one of the nine essential amino acids: tryptophan.
Because tryptophan is missing, collagen is technically labeled as an incomplete protein. This is why some people argue it shouldn't count. If you ate nothing but collagen, your body eventually wouldn't have the "letters" it needs to build certain tissues. But nobody lives on collagen alone.
Key Takeaway: Collagen is an incomplete protein because it lacks the essential amino acid tryptophan. While it is incredibly rich in glycine and proline, it cannot be your sole source of protein if you want to support all of your body's physiological functions.
Collagen Peptides
The PDCAAS Score: Why Labels Can Be Tricky
If you look at the back of a bag of BUBS Naturals Collagen Peptides, you will see the protein count clearly listed. However, you might notice that the "Percent Daily Value" (% DV) is often left blank or listed as zero. This isn't a mistake or a way to hide anything. It is a result of federal labeling regulations.
The FDA uses a system called the Protein Digestibility Corrected Amino Acid Score (PDCAAS). This system measures protein quality based on both the amino acid requirements of humans and our ability to digest it. The scores range from 0.0 to 1.0.
- Whey Protein: Usually scores a 1.0 (the highest possible score).
- Soy Protein: Also scores near a 1.0.
- Beef: Scores around a 0.92.
- Collagen: Scores a 0.0.
A score of 0.0 sounds bad, but it simply means that the protein is missing at least one essential amino acid. Because collagen has zero tryptophan, the formula used to calculate the PDCAAS automatically drops the entire score to zero.
Legally, if a protein has a PDCAAS of 0.0, companies are often not allowed to list a Percent Daily Value. This creates a weird paradox where a product can have 18 grams of protein per serving but still show 0% for the daily value. This is why it is important to look at the grams of protein rather than the percentages.
How Much Collagen Can You Actually Count?
So, if it is an incomplete protein with a score of 0.0, how much of it can you actually add to your daily total? You don't have to guess. Recent research has looked into exactly how much collagen a person can consume while still maintaining a healthy amino acid balance.
Studies have shown that you can replace up to 36% of your daily protein intake with collagen peptides without missing out on essential nutrients, provided the rest of your diet is varied. For example, if your goal is to eat 150 grams of protein per day, about 54 of those grams could come from collagen.
This is excellent news for anyone using collagen for joint health or skin recovery. It means those two scoops in your morning coffee or post-workout shake absolutely contribute to your daily goals. You just need to ensure the other 64% to 70% of your protein comes from complete sources like meat, fish, eggs, dairy, or a well-rounded plant-based protein.
The Math of a Typical Day
Let’s look at how this works in a real-world scenario. Imagine you are an active adult aiming for 120 grams of protein.
- Breakfast: 3 eggs (18g protein) + 1 scoop of collagen in coffee (18g protein)
- Lunch: Chicken breast over salad (35g protein)
- Snack: Greek yogurt (15g protein)
- Dinner: Steak or Salmon (34g protein)
In this day, your total is 120 grams. Your collagen made up 15% of your total intake. This is well within the "safe" range where the collagen is fully utilized by the body and your amino acid needs are totally met by the other meals.

Join The ClubCollagen vs. Whey: Choosing the Right Tool
We often get asked if someone should take collagen instead of whey protein. The answer depends entirely on your goals. They are different tools designed for different jobs.
| Feature | Collagen Peptides | Whey Protein |
|---|---|---|
| Protein Type | Incomplete (Missing Tryptophan) | Complete (All 9 Essentials) |
| Primary Goal | Joint, Skin, and Gut Health | Muscle Building and Recovery |
| Amino Acid Profile | High Glycine, Proline, Hydroxyproline | High Leucine (BCAAs) |
| Digestion | Very Easy (Hydrolyzed) | Fast (but can be tough on lactose-sensitive) |
| Mixing | Dissolves in hot or cold liquids | Best in cold shakes/smoothies |
If your primary goal is to pack on as much lean muscle as possible, whey is the gold standard because it is high in leucine. Leucine is the "on switch" for muscle protein synthesis. Collagen is very low in leucine, so it isn't the best choice for triggering muscle growth immediately after a lifting session.
However, if you are focused on recovery, joint longevity, and maintaining healthy connective tissue, collagen is superior. The high concentration of glycine and proline provides the specific materials your body needs to repair tendons and ligaments. We recommend using both. Many of our athletes use creatine for muscle performance and our Collagen Peptides for structural integrity.
Myth: Collagen is a waste of money because it's an incomplete protein. Fact: While incomplete, collagen contains high concentrations of functional amino acids like glycine that are not found in high amounts in other protein sources. These are essential for joint and skin health.
The Role of Hydrolyzed Peptides
When you see the term "hydrolyzed" on our BUBS Naturals packaging, it refers to the process used to make the protein easier for your body to use. Raw collagen is a massive, tough molecule. Your body has a hard time breaking it down in its natural state.
Hydrolysis uses enzymes to break those long protein chains into smaller pieces called peptides. These peptides are "bioavailable," meaning they are ready for your body to absorb. This is why our collagen dissolves so easily in your morning coffee. It is already broken down.
Once absorbed, these peptides travel through the bloodstream. Some are broken down further into individual amino acids, while others stay as peptides. Research suggests these peptides may act as signaling molecules, telling your body to "wake up" its own collagen production in the skin and joints. This is a benefit you simply don't get from eating a standard chicken breast or drinking a whey shake.
Benefits Beyond the Macro Count
While we’ve established that collagen counts toward your protein total, it’s worth noting why you’d want to count it in the first place. It offers specific wellness benefits that go beyond just hitting a macro number.
1. Joint and Tendon Support
As we age or train hard, the collagen in our joints begins to wear down. This can lead to that "creaky" feeling or nagging injuries. Supplementing with collagen provides the glycine and proline needed to support cartilage health. Many people find that consistent use helps with overall joint comfort during high-impact activities like running or heavy lifting.
2. Skin Elasticity and Aging
Collagen makes up about 75% of your skin’s dry weight. It provides the structure that keeps skin looking firm. As natural production slows down in your 30s and 40s, you might notice more fine lines. Because collagen peptides support the dermal layer of the skin, regular intake can help maintain hydration and elasticity.
3. Gut Health
The lining of your digestive tract is made of connective tissue. Some evidence suggests that the amino acids in collagen, particularly glycine, may help support the integrity of the gut lining. This is particularly important for athletes who put their bodies under significant stress, which can sometimes lead to digestive upset.
4. Recovery for the "Non-Muscle" Parts
When we talk about recovery, we usually focus on muscles. But your bones, ligaments, and tendons take a beating, too. These tissues are made almost entirely of collagen. By including it in your daily routine, you are supporting the parts of your body that hold your muscles together.
Note: Collagen is not a "magic pill" for weight loss. While it is protein and can help you feel full (satiety), it should be used as part of a balanced diet and exercise plan, not as a shortcut for shedding pounds.
How to Maximize Your Collagen Intake
To get the most out of your collagen and ensure it is "counting" as effectively as possible, there are a few best practices to follow.
Pair it with Vitamin C
Your body needs Vitamin C to actually synthesize collagen. If you are deficient in Vitamin C, it doesn't matter how much collagen powder you take; your body will struggle to turn those amino acids into new tissue. This is why we often suggest taking your collagen with a squeeze of lemon or alongside our Vitamin C supplement. It acts as a co-factor that helps the process along.
Mix it into Your Existing Routine
One of the best things about our collagen is that it is unflavored and dissolves effortlessly. You don't have to choke down a chalky shake.
- Morning Coffee: This is the most popular way. It adds a creamy texture without changing the flavor.
- Post-Workout: Add a scoop to your existing protein shake to get the benefits of both whey (muscle) and collagen (joints).
- Smoothies: It blends perfectly with fruits and greens.
- Baking: You can even add it to pancake batter or oatmeal for a hidden protein boost.
Consistency Over Intensity
You won't see the benefits of collagen by taking a massive dose once a week. The research shows that the best results come from consistent, daily use. Whether it’s 10 grams or 20 grams, the key is making it a non-negotiable part of your daily habit. Most users report seeing and feeling a difference in their joints and skin after about 4 to 8 weeks of daily use.
Is Collagen Safe for Everyone?
For the vast majority of people, collagen is an incredibly safe and well-tolerated supplement. Because it is a natural part of the human body and is sourced from food-grade animals, side effects are rare.
However, if you have a specific allergy to the source (such as fish for marine collagen or beef for bovine collagen), you should obviously avoid it. Also, because it is an animal product, it is not suitable for vegans. If you are pregnant or breastfeeding, it is always a smart move to check with your healthcare provider before adding any new supplement to your routine, though most find collagen to be a helpful way to meet increased protein needs during those times.
How to Check for Quality
Not all collagen is created equal. If you are going to count these peptides toward your daily protein goal, you want to make sure you are getting the clean stuff. When shopping for collagen, look for:
- Grass-Fed and Pasture-Raised: This ensures the animals were raised in a healthy environment without being pumped full of hormones.
- Single Ingredient: You don't need fillers, sweeteners, or artificial flavors. Pure hydrolyzed collagen is all you need.
- Third-Party Testing: This is huge. At BUBS Naturals, our products are NSF for Sport certified. This means they have been tested for purity and do not contain any banned substances. It is the gold standard for athletes and military members who can't afford to have a contaminated product.
Bottom line: You can and should count collagen as protein, provided it doesn't exceed about a third of your daily intake. It is a functional supplement that supports the structural health of your body in ways that standard protein sources cannot.

FAQ
Does collagen protein count toward muscle growth?
While collagen contributes to your total protein intake, it is not the most effective protein for building muscle because it is very low in leucine, the amino acid that triggers muscle growth. For building lean mass, it is best to pair collagen with a complete protein source like whey or lean meat.
Can I use collagen as a meal replacement?
No, you should not use collagen as a meal replacement. Because it lacks the essential amino acid tryptophan and is not a complete protein, it does not provide the full spectrum of nutrients your body needs to thrive. It is meant to supplement a balanced diet, not replace real food.
Why does my collagen label say 0% daily value for protein?
This is due to FDA labeling laws. Since collagen is an "incomplete" protein with a PDCAAS score of 0.0, the law often prevents companies from listing a Percent Daily Value. However, the grams of protein are still real and will contribute to your daily nutritional needs.
Is it okay to take collagen every day?
Yes, taking collagen daily is actually the recommended way to use it. Research suggests that consistent, long-term use is necessary to see improvements in joint comfort and skin elasticity. Most people find that one to two scoops a day is the "sweet spot" for seeing results.
