Introduction
You’re staring at your tracking app, thumb hovering over the protein entry for your morning coffee. You’ve added a scoop of Collagen Peptides, but a quick search reveals a heated debate: does it actually count? Many people wonder if the 10 or 20 grams of protein listed on the label should contribute to their daily targets or if it's "empty" protein that doesn't support their fitness goals.
At BUBS Naturals, we believe in keeping nutrition simple, transparent, and grounded in real science. Collagen is undeniably a protein, but it doesn't behave quite like the chicken breast or whey shake you might be used to. Its unique amino acid profile means it serves a different purpose in your body, focusing on structural integrity rather than just muscle hypertrophy.
In this guide, we will break down the biochemistry of collagen, explain why quality scores matter, and answer the specific question: should I count collagen protein in my macros? We’ll provide a clear framework for how to log your intake so you can maintain your progress without overthinking your nutrition.
Quick Answer: Yes, you should count collagen toward your total daily protein macros because it provides calories and essential nitrogen to your body. However, because it is an "incomplete" protein, it should ideally make up no more than 30% to 36% of your total intake to ensure you are getting enough of all nine essential amino acids.
Understanding the Structure of Collagen
To determine if collagen belongs in your macro count, we first need to look at what it actually is. Collagen is the most abundant protein in the human body, acting as the structural "glue" for your skin, joints, bones, tendons, and ligaments. Unlike other proteins that are primarily used for metabolic functions or muscle repair, collagen is built to provide tensile strength and elasticity.
Most supplements you find today are labeled as "hydrolyzed collagen" or "collagen peptides." This means the long, complex protein chains have been broken down into smaller pieces using a process called hydrolysis. These smaller peptides are easier for your digestive system to handle and enter your bloodstream more efficiently. When you consume them, your body receives a concentrated dose of specific amino acids that are rare in other food sources.
However, the reason people question its place in a macro plan is its specific amino acid profile. Every protein is made up of amino acids, which are the building blocks of life. There are 20 different amino acids, and your body needs all of them to function at its peak. Collagen is incredibly high in glycine, proline, and hydroxyproline, which are fantastic for joint health, but it lacks the diversity found in "complete" proteins.

The Difference Between Complete and Incomplete Proteins
The core of the "should I count it" debate lies in the distinction between complete and incomplete proteins. Your body requires nine "essential" amino acids (EAAs) that it cannot produce on its own. These must come from your diet. If a protein source contains all nine in sufficient amounts, it is considered "complete." Common examples include beef, poultry, fish, eggs, and dairy.
Collagen is technically an incomplete protein because it is missing one specific essential amino acid: tryptophan. It is also quite low in other essential amino acids like leucine, which is the primary driver of muscle protein synthesis. Because it lacks tryptophan, it cannot be your only source of protein. If you tried to live on collagen alone, your body would eventually face a protein deficiency because it wouldn't have the materials needed to repair various tissues and create vital enzymes.
Does this mean the protein isn't "real"? Not at all. It just means it has a specialized job. Think of complete proteins as the general contractors that can build any part of a house, while collagen is the specialist who only handles the foundation and the plumbing. Both are necessary, but you can’t build the whole house with just the plumber.
Key Takeaway: Collagen is an incomplete protein because it lacks the essential amino acid tryptophan. While it provides high amounts of specific amino acids like glycine, it cannot support all bodily functions on its own and must be paired with complete protein sources.
Why Quality Scores Impact Macro Tracking
In the world of nutrition science, researchers use several methods to grade protein quality. The most common is the Protein Digestibility Corrected Amino Acid Score (PDCAAS). This score measures how well a protein provides the essential amino acids humans need, adjusted for how easily we can digest it.
The scale runs from 0.0 to 1.0. A score of 1.0 is considered "perfect" for meeting human requirements. Whey protein, egg whites, and soy protein isolate typically score a 1.0. Because collagen is missing tryptophan, its PDCAAS score is technically 0.0. This is often why you’ll see an asterisk on nutrition labels next to the protein count or a blank space where the "Percent Daily Value" should be.
Under FDA regulations, companies often cannot list a percentage for the Daily Value of protein if the source has a score of 0.0. This leads many consumers to believe that those 10 to 20 grams of protein don't count toward their macros. However, from a caloric and metabolic standpoint, they absolutely do. Every gram of collagen protein still contains 4 calories and still contributes to your body’s nitrogen balance.

Join The ClubThe Role of Nitrogen Balance in Recovery
To understand why collagen counts, we have to look at nitrogen. Protein is the only macronutrient that contains nitrogen. When you track your macros, you are essentially tracking how much nitrogen you are providing your body to stay in an "anabolic" or building state. If you are taking in more nitrogen than you are losing, your body has the resources it needs to repair tissue.
Collagen is a potent source of nitrogen. Even though it lacks tryptophan, the massive amounts of glycine and proline it provides are utilized by the body for critical tasks. For example, glycine is a precursor to creatine, which helps with power output, and glutathione, a powerful antioxidant. By logging collagen in your macros, you are accurately accounting for the nitrogen you’ve provided your body for these background processes.
If you ignored collagen in your tracking, you might end up over-consuming total calories. If your goal is 150 grams of protein and you take 20 grams of collagen but don't count it, you are actually consuming 170 grams of protein and an extra 80 calories. Over time, those unaccounted-out calories can stall fat loss or affect your body composition goals.
Myth: Collagen protein is "fake" protein because it has a low quality score.
Fact: Collagen provides real calories and nitrogen that your body uses for structural repair, creatine production, and antioxidant support. It should be tracked as part of your total caloric intake.
The 36 Percent Rule for Macro Planning
If you are wondering how much of your daily protein can safely come from collagen, there is actually some solid research on the topic. A study published in the journal Nutrients looked at how much collagen a person could consume without creating an amino acid imbalance.
The researchers found that collagen peptides can make up about 30% to 36% of a person’s total daily protein intake while still allowing that person to meet all their essential amino acid requirements. This assumes the remaining 64% to 70% comes from high-quality, complete sources like meat, eggs, or whey.
For a person aiming for 150 grams of protein per day, this means they could realistically count up to 54 grams of collagen protein toward that goal. This is great news for those who prefer the ease of a supplement or who want the joint-support benefits of collagen without feeling like they have to eat an extra chicken breast to "make up" for it. Our Collagen Peptides collection is designed to fit into this balanced approach, offering clean options that support your joints while contributing to your daily targets.
Collagen vs. Whey: Which One Should You Prioritize?
When tracking macros, it helps to view whey and collagen as tools with different purposes. They are not interchangeable, but they are complementary.
Whey protein is exceptionally high in leucine, the amino acid that triggers muscle growth. This makes it the ideal choice for a post-workout shake when your primary goal is repairing muscle fibers. If you only tracked collagen and ignored whey or animal protein, you might find that your muscle recovery is slower and your strength gains plateaus.
On the other hand, whey is not particularly high in the specific amino acids that build connective tissue. This is where collagen excels. If you are an athlete who puts a lot of stress on your knees, shoulders, and ankles, the glycine and proline in collagen are more valuable for those specific tissues than the leucine in whey.
| Feature | Collagen Peptides | Whey Protein |
|---|---|---|
| Protein Status | Incomplete (Lacks Tryptophan) | Complete (All 9 EAAs) |
| Primary Benefit | Joint, Skin, and Gut Support | Muscle Growth and Repair |
| Digestion | Very Easy (Hydrolyzed) | Fast (May cause bloating for some) |
| Leucine Content | Low | Very High |
| Best Time to Take | Anytime (often morning or pre-workout) | Post-Workout |
How to Log Collagen in Your Macro Tracking App
Most people use apps like MyFitnessPal, Cronometer, or MacroFactor to keep tabs on their daily intake. When you scan a tub of collagen, the app will usually populate the protein field with the grams listed on the label. Here is the most effective way to handle this without overcomplicating your life:
- Count the Grams: If the label says 10g of protein, log 10g of protein. It contributes to your total caloric daily limit and provides nitrogen.
- Monitor Your "Complete" Sources: Ensure that the majority of your protein (at least 70%) is coming from complete sources. If you hit your 150g goal, but 100g of it was from collagen, you are likely missing out on essential amino acids.
- Use it for Satiety and Structure: Many people find that adding collagen to their morning coffee helps them feel full until lunch. This satiety is a real benefit of protein, regardless of whether it's complete or incomplete.
- Don't Stress the "Asterisk": If your app shows a lower "Percent Daily Value" than the total grams would suggest, don't worry. The app is just following FDA labeling rules based on the PDCAAS score.
By following these steps, you ensure that you are getting the joint and skin benefits of collagen while still hitting the amino acid thresholds required for muscle maintenance and general health.
Practical Scenarios for Tracking
Let’s look at how this looks in a real-world setting. You’ve just finished a morning training session. You know you need protein to recover, so you grab a coffee and stir in two scoops of BUBS Naturals Collagen Peptides. That’s 20 grams of protein.
In this scenario, those 20 grams definitely count toward your total daily macros. However, if that is the only protein you have for several hours, you aren't providing your muscles with the leucine they need to start the repair process. A better move would be to have that collagen coffee alongside a couple of eggs or a high-quality protein shake. This "completes" the amino acid profile of your meal, allowing your body to use the collagen for your joints and the EAAs for your muscles.
Another common scenario is using collagen before a long run or a hike. Because collagen is easy on the stomach and supports connective tissue, it’s a great pre-activity supplement. In this case, you log it to keep your calories accurate, knowing that the specific amino acids will be available in your bloodstream to support your tendons as they take the impact of the trail.
Bottom line: Count every gram of collagen toward your daily protein and calorie goals, but make sure you are also eating a wide variety of complete protein sources to cover all your essential amino acid needs.
Why Quality Matters for Your Macros
Not all collagen is created equal. When you are counting these grams toward your macros, you want to ensure those grams are coming from a clean, high-quality source. Many cheaper collagen products use fillers or are sourced from animals raised in poor conditions, which can lead to a less effective amino acid profile or the presence of unwanted additives.
At BUBS Naturals, our Collagen Peptides are grass-fed and pasture-raised. They are also NSF for Sport certified, which means they undergo rigorous third-party testing to ensure they are free from contaminants and banned substances. When you log 20 grams of our collagen in your tracker, you can be confident that you are getting exactly what the label says—no fillers, no BS, just clean protein that supports your active lifestyle.
Conclusion
The question of whether you should count collagen in your macros is ultimately about accuracy. If you want a precise picture of your daily nutrition, you must count it. It provides calories, it provides nitrogen, and it provides functional building blocks for your body's structural health. While it shouldn't be your only protein source, it is a valuable part of a well-rounded diet.
Nutrition doesn't have to be a complicated puzzle. By focusing on whole foods, supplement quality, and a balanced approach to amino acids, you can reach your goals while feeling your best. At BUBS Naturals, we are driven by that same commitment to simplicity and excellence, a legacy inspired by our friend Glen "BUB" Doherty.

FAQ
Does collagen protein help build muscle?
Collagen is not the most effective protein for building muscle because it lacks the essential amino acid tryptophan and is low in leucine, the trigger for muscle protein synthesis. While it provides nitrogen that supports overall body tissue, you should rely on complete proteins like whey or meat for muscle hypertrophy.
Can I replace my whey protein with collagen?
You should not replace whey with collagen entirely if your goal is muscle growth and recovery. Whey is a complete protein that stimulates muscle repair, while collagen is an incomplete protein focused on joint and connective tissue health. Using both together often provides the best results for active individuals.
Why do some labels say collagen has 0% daily value of protein?
The FDA requires the Percent Daily Value (%DV) on nutrition labels to be based on protein quality scores like PDCAAS. Since collagen lacks the essential amino acid tryptophan, its score is 0.0, which means it cannot legally contribute to the %DV even though it contains real grams of protein and calories.
How many scoops of collagen can I have per day?
Most research suggests that collagen can safely make up about 30% to 36% of your total daily protein intake. For most people, this equates to 2 to 3 scoops per day, provided they are also consuming plenty of complete protein sources like eggs, fish, or poultry.
