Introduction
You’ve likely seen the label on a tub of collagen and noticed something curious. While it might list 10 or 20 grams of protein per serving, the "Percent Daily Value" often sits at zero. This leads to a frustrating question for anyone tracking their macros: does collagen count towards protein intake, or are you just drinking "empty" protein?
At BUBS Naturals, we believe in total transparency and science-backed nutrition. Whether you are a veteran athlete or someone just trying to stay mobile and healthy, understanding what you put in your body is non-negotiable. You need to know if that scoop in your morning coffee is helping you hit your daily targets or if you need to adjust your meal prep.
This article explores the technical differences between collagen and other proteins, how your body uses those amino acids, and exactly how much collagen can safely contribute to your daily goals. The short answer is that it does count, but the "how" and "why" matter more than the number on the scale.
Quick Answer: Yes, collagen counts toward your daily total protein intake, but it is an incomplete protein. Research suggests that collagen can safely make up about one-third of your total daily protein as long as the rest of your diet provides a variety of complete protein sources.
Understanding the Building Blocks: What Is Protein?
To understand why people debate whether collagen "counts," we have to look at what protein actually is. Think of protein as a massive structure made of smaller bricks called amino acids. There are 20 different amino acids that your body uses to build and repair everything from muscle fibers to enzymes and hormones.
Out of those 20, nine are considered "essential." This means your body cannot manufacture them on its own. You must get them from your diet. If a protein source contains all nine essential amino acids in sufficient amounts, it is called a "complete protein." This includes things like eggs, beef, dairy, and whey.
If a protein source is missing even one of those nine, it is labeled an "incomplete protein." Most plant-based proteins, like beans or nuts, fall into this category. Collagen also falls here because it is missing one specific essential amino acid: tryptophan.
Collagen Peptides
The Tryptophan Gap and Why It Matters
Collagen is the most abundant protein in your body. It acts as the scaffolding for your skin, hair, nails, joints, and even your gut lining. Because it has such a specific job, it is packed with a unique profile of amino acids—specifically glycine, proline, and hydroxyproline.
However, because it lacks tryptophan, the scientific community has historically viewed it as a "lower quality" protein. Tryptophan is necessary for the production of serotonin and melatonin, and without it, your body cannot use the other amino acids in that specific protein chain to build muscle tissue through a process called muscle protein synthesis.
This is why, on a nutritional label, collagen doesn't contribute to the Percent Daily Value (%DV). The FDA bases that percentage on the "protein quality," and since collagen is technically incomplete, its score is adjusted down to zero for labeling purposes. But that does not mean the grams of protein are non-existent or useless to your body.
Key Takeaway: Collagen is an incomplete protein because it lacks tryptophan. While this makes it "lower quality" for muscle building compared to whey, it is still a significant source of functional nitrogen and specific amino acids your body needs for connective tissue.
The 36% Rule: What the Research Says
A common myth in the fitness world is that if a protein is incomplete, your body simply wastes it or burns it as fuel rather than using it for repair. Recent science has debunked this "all or nothing" view.
A landmark study published in the journal Nutrients in 2019 looked at this exact issue. Researchers wanted to know how much collagen someone could eat before it negatively affected their amino acid balance. They found that up to 36% of a person’s daily protein intake could come from collagen peptides without any negative impact on the body’s ability to function or maintain its essential amino acid levels.
In practical terms, if your goal is to eat 150 grams of protein per day, about 54 of those grams could come from collagen. As long as the remaining 96 grams come from complete sources like meat, fish, or eggs, your body will have more than enough tryptophan to fill the gap left by the collagen. We design our products, like our Collagen Peptides, to fit into this kind of balanced, real-world nutrition plan.
Myth: If you eat an incomplete protein like collagen, your body can’t use it for anything. Fact: Your body pools amino acids from everything you eat throughout the day. As long as you consume complete proteins in other meals, the amino acids in collagen are fully utilized.

Join The ClubCollagen vs. Whey: Choosing the Right Tool for the Job
If you are trying to decide between collagen and a standard protein powder like whey, you need to look at your goals. They are not interchangeable; they are different tools in your recovery kit.
For Muscle Building
If your primary goal is hypertrophy (building muscle size) or maintaining muscle mass during a fat-loss phase, whey protein or a complete animal-based protein is superior. This is because whey is high in leucine, a branched-chain amino acid (BCAA) that acts as the "on switch" for muscle growth. Collagen is very low in leucine and, as we’ve established, lacks tryptophan.
For Recovery and Longevity
If you are focused on joint health, recovering from a ligament injury, or supporting your skin as you age, collagen is the clear winner. You cannot get the high concentrations of glycine and proline found in collagen from a standard whey shake. These amino acids are "conditionally essential," meaning your body can make some, but under the stress of training or aging, it often can’t make enough.
Many of our athletes use both. They might take our Collagen Peptides in the morning for joint support and use a complete protein or a high-protein meal after a heavy lifting session for muscle repair.
Bottom line: Use whey or whole foods to hit your leucine requirements for muscle growth, and use collagen to provide the specific raw materials for your joints, tendons, and skin.
How to Track Collagen in Your Macros
If you are using an app to track your food, you should count the grams of collagen toward your total daily protein. If your scoop of Collagen Peptides says 20 grams of protein, log 20 grams.
However, you should keep the "one-third rule" in mind. Do not rely on collagen as your only source of protein for the day. If you are a 200-pound person aiming for 200 grams of protein, you shouldn't be getting 100 grams from collagen. Keep it as a supplement—an "extra" that supports your foundation—rather than the foundation itself.
At BUBS Naturals, we focus on making products that mix easily into things you’re already doing. Whether it’s in your coffee or a smoothie, it should feel like a natural part of your routine. We use a high-quality, grass-fed, and pasture-raised source because we know that the cleaner the source, the better your body can put those amino acids to work.

Collagen’s Hidden Benefits Beyond "Protein"
While the debate usually centers on the amino acids, collagen offers benefits that traditional protein powders don't. When you consume collagen, you aren't just getting "protein grams"; you are getting functional peptides.
Gut Integrity
Glycine and glutamine are two amino acids found in high amounts in collagen. Both are critical for maintaining the integrity of your gut lining. A strong gut lining helps prevent "leaky gut" and ensures that you are actually absorbing the other nutrients and proteins you consume.
Joint and Tendon Repair
Standard protein sources are great for the "meat" of the muscle, but they don't do much for the "glue" that holds it to the bone. Collagen has been shown to support the density of ligaments and tendons. This is why many people who suffer from chronic "achy" joints find relief after consistent collagen use.
Metabolic Health
Glycine also plays a role in the production of glutathione, your body’s master antioxidant. This helps with detoxification and reducing oxidative stress from hard training. When you view collagen through this lens, the question of whether it "counts" toward protein seems less important than whether it helps you stay in the game.
Common Pitfalls: Quality and "Vegan" Collagen
Not all collagen is created equal. If you are going to count these grams toward your daily intake, you need to ensure they are bioavailable.
Hydrolyzed Is Key
You should only use hydrolyzed collagen, often called collagen peptides. The "hydrolyzation" process uses enzymes to break the long, tough collagen chains into tiny pieces. This makes it much easier for your gut to absorb. If you just eat gelatin or low-quality collagen, your body has to work much harder to break it down, and you might not get the full amino acid profile you're paying for.

The Vegan Question
You might see products marketed as "vegan collagen." To be clear: there is no such thing as vegan collagen. Collagen is an animal-derived protein. Vegan "collagen builders" are usually just collections of Vitamin C, zinc, and a few amino acids intended to help your body produce its own collagen. While these can be helpful, they do not provide the same concentrated peptides as a true bovine or marine collagen supplement.
Our focus is on the real thing—clean, single-ingredient bovine collagen that is third-party tested and NSF for Sport certified. This means athletes at the highest levels can trust that what is on the label is exactly what is in the tub.
Practical Tips for Your Routine
To get the most out of your collagen and ensure it’s helping you reach your goals, follow these simple guidelines:
- Pair it with Vitamin C: Your body requires Vitamin C to actually "knit" those collagen fibers together. If you are taking a scoop of our Collagen Peptides, make sure you are also getting enough Vitamin C through fruit, vegetables, or a supplement.
- Timing Matters for Joints: Some research suggests that taking collagen about 30 to 60 minutes before a workout can help the amino acids circulate in your bloodstream just as your joints are being loaded, potentially increasing its effectiveness.
- Be Consistent: Collagen isn't a one-and-done supplement. Most studies showing benefits for skin, hair, and joints require 8 to 12 weeks of daily use.
- Count it, but don't over-rely on it: Log your collagen grams to hit your daily total, but make sure your meals are built around complete proteins like chicken, beef, fish, or eggs.

FAQ
Can I use collagen as my only post-workout protein?
It is not recommended to use collagen as your only source of protein after a workout. Because collagen is low in leucine and lacks tryptophan, it does not stimulate muscle protein synthesis as effectively as a complete protein like whey or a whole-food meal. For the best results, pair your collagen with a complete protein source or save the collagen for a different time of day.
For more context, read about collagen peptides and muscle recovery.
Why does the label say 0% Daily Value if it has protein?
The FDA requires the Percent Daily Value (%DV) for protein to be based on the "quality" of the protein, measured by its amino acid profile and digestibility. Since collagen is an incomplete protein (missing tryptophan), its quality score is technically zero in the eyes of the FDA. However, your body still absorbs and uses the grams of protein listed for other vital functions like joint and skin repair.
Is it okay to take collagen every day?
Yes, taking collagen daily is not only safe but generally necessary to see real results. Most clinical studies on joint health and skin elasticity show that benefits appear after 8 to 12 weeks of consistent, daily use. Because it is a food-based supplement, it can be a permanent part of your long-term wellness and recovery routine.
How many scoops of collagen can I have per day?
Most people find that 1 to 2 scoops (roughly 10–20 grams of protein) per day is the "sweet spot" for seeing benefits. According to research, you can safely consume up to about one-third of your total daily protein from collagen. For example, if you aim for 120 grams of protein daily, up to 40 grams (about 4 scoops) could come from collagen without disrupting your amino acid balance.
