Introduction

Did you know that collagen makes up roughly one-third of all the protein in your body? It is the literal scaffolding that holds us together, acting as the primary structural component for our skin, bones, tendons, ligaments, and even our blood vessels. However, as early as our mid-20s, our body’s natural production of this vital protein begins a slow, steady decline. By the time we hit 40, we may have lost up to 25% of our collagen stores, and that number continues to climb every year thereafter. This biological reality often leaves people asking one fundamental question: what foods contain a lot of collagen, and how can we get more of it back into our systems?

At BUBS Naturals, we approach wellness with the same grit and dedication that defined our inspiration, Glen “BUB” Doherty. Glen was a Navy SEAL, an adventurer, and a man who lived life to the absolute fullest. In his honor, we are committed to providing clean, effective, and science-backed nutrition that fuels a life of purpose. Part of that mission involves educating our community on how to optimize their health through both whole foods and high-quality supplementation. Whether you are scaling a mountain or just trying to keep your joints feeling fluid during your morning run, understanding the role of collagen-rich foods is a game-changer.

In this exploration, we are going to dive deep into the dietary landscape of collagen. We’ll discuss why traditional diets were naturally higher in this protein than our modern Western diet, which specific animal sources provide the most direct collagen, and how certain plant-based "cofactors" act as the spark plugs for your body’s own collagen synthesis. We will also address the practical challenges of relying solely on whole foods and how our Collagen Peptides can bridge the gap.

Our goal today is to give you a comprehensive roadmap. By the end of this post, you will understand not just which foods to put in your grocery cart, but the biological "why" behind those choices. We want to empower you to take control of your recovery, your mobility, and your long-term vitality. Because at the end of the day, we believe that when you feel better, you do better—and that’s how we continue to honor Glen’s legacy and our commitment to donating 10% of all profits to veteran-focused charities.

The Structural Science of Collagen

Before we can identify what foods contain a lot of collagen, we must understand what collagen actually is. Collagen is a "long-chain" protein composed of specific amino acids: glycine, proline, and hydroxyproline. Unlike whey or soy protein, which have broad amino acid profiles used for muscle building, collagen’s specific structure is designed for durability and elasticity.

Think of collagen like a high-tensile steel cable. In the body, three chains of amino acids wrap around each other in a triple-helix structure. These fibers then bundle together to form fibrils, which eventually become the tough, flexible tissues that make up your joints and skin. Because this structure is so unique, the body requires very specific "building blocks" to manufacture it.

There are over 28 different types of collagen, but roughly 80–90% of the collagen in your body consists of Types I, II, and III. Type I is the most abundant and is found in skin, tendons, and bone. Type II is primarily found in cartilage, making it essential for joint cushioning. Type III works alongside Type I and is common in the walls of arteries and hollow organs. When we look at food sources, we are looking for ingredients that either provide these types directly or provide the raw materials needed for our bodies to build them.

Why Modern Diets Are Collagen-Deficient

Historically, human beings followed a "nose-to-tail" approach to eating. Our ancestors didn't just eat the lean muscle meat; they consumed the skin, the tendons, the connective tissues, and the marrow. They simmered bones for days to create nutrient-dense broths. This wasn't just a matter of frugality; it was a biological necessity. These parts of the animal are the most concentrated sources of collagen.

In contrast, the modern diet focuses almost exclusively on "clean" muscle meats like chicken breasts or lean steaks. While these are great sources of essential amino acids for muscle repair, they are notoriously low in the specific amino acids required for collagen production. We have effectively engineered collagen out of our daily meals. This "collagen gap" is part of why so many of us experience joint discomfort or a decline in skin health as we age.

To correct this, we have to look back at traditional food preparation and prioritize the parts of the animal that we’ve spent the last century throwing away. Integrating Collagen Peptides into your routine is one of the most efficient ways to close this gap, but understanding the whole-food origins is the first step toward a holistic wellness strategy.

The Gold Standard: Bone Broth

When people ask what foods contain a lot of collagen, bone broth is almost always at the top of the list. Bone broth is created by simmering the bones and connective tissues of animals—usually cattle, chickens, or fish—in water for an extended period, often up to 24 or 48 hours.

During this slow-simmering process, the collagen in the bones and joints breaks down into gelatin, which then dissolves into the liquid. This gelatin is essentially "cooked" collagen. When you consume bone broth, you are taking in a bioavailable form of the collagen proteins and the minerals that support bone health, such as calcium, magnesium, and phosphorus.

The quality of the broth depends entirely on the quality of the source. At BUBS, we are big believers in grass-fed and pasture-raised standards. This ensures the animal was healthy and free from the inflammatory markers often found in grain-fed livestock. If you’re making bone broth at home, look for "knuckle bones" or "marrow bones," as these have the highest concentration of connective tissue.

For those who don't have 24 hours to wait for a pot to simmer, our Collagen Peptides Collection offers a way to get those same benefits in a form that dissolves instantly in your morning coffee or post-workout shake. It’s the spirit of the old-world tradition, refined for the modern adventurer’s schedule.

Poultry and the Power of Cartilage

Chicken is a staple in most households, but if you’re only eating the breast, you’re missing out on the collagen. Chicken is a particularly rich source of Type II collagen, which is the primary form found in human joint cartilage. This is why many joint-specific supplements are derived from chicken sources.

If you’ve ever noticed the "jelly-like" substance that forms at the bottom of a pan after roasting a whole chicken, you’ve seen collagen in its natural form. To maximize your intake:

  1. Eat the skin: The skin of the chicken is almost pure collagen and fat. While we were taught to avoid it for decades, it is actually where the structural nutrients reside.
  2. Utilize the joints: When eating chicken wings or drumsticks, the gristle (cartilage) at the ends of the bones is packed with Type II collagen.
  3. Use the whole bird: After roasting a chicken, don't toss the carcass. Use it to make a quick pressure-cooker broth to extract those remaining proteins.

Integrating these habits can significantly boost your dietary collagen intake. We often suggest pairing a protein-heavy meal with our Apple Cider Vinegar Gummies to support digestive health, ensuring your body can effectively break down and utilize those dense animal proteins.

Fish and Marine Collagen

Fish is another powerhouse when it comes to collagen-rich foods, specifically Type I collagen. Marine collagen is often praised for its high bioavailability, meaning the smaller particle size of the collagen peptides allows for easier absorption into the bloodstream.

However, the collagen in fish isn't found in the "filet" that we usually eat. It is concentrated in the skin, scales, and bones. This is why traditional cultures often ate small fish whole (like sardines or anchovies) or used fish heads to make soups and stews.

If you aren't a fan of eating fish skin, you can still benefit from marine sources by choosing wild-caught fish and ensuring you aren't overcooking the delicate tissues. For those who prefer a land-based source, our Collagen Peptides are sourced from grass-fed, pasture-raised bovine hides, providing a robust Type I and Type III profile that rivals the best marine sources without the fishy aftertaste.

Eggs and the Shell Membrane

Eggs are a unique entry in the list of what foods contain a lot of collagen. While the egg white and yolk don't contain collagen themselves, they are rich in the amino acids proline and glycine, which are the precursors for collagen synthesis.

The real collagen "gold mine" in an egg is the membrane—the thin layer between the shell and the egg white. Have you ever peeled a hard-boiled egg and noticed that translucent film? That is eggshell membrane, and it is naturally rich in collagen, glucosamine, and chondroitin. While it’s difficult to eat enough egg membranes to see a significant difference, consuming whole eggs provides your body with the sulfur and amino acids it needs to support its own collagen-building machinery.

The Plant-Based "Cofactors" for Collagen

If you are following a plant-based diet, you might be wondering where you fit into this conversation. It is a common misconception that there is such a thing as "vegan collagen." Collagen is an animal protein; plants simply do not have it. However, plants are absolutely essential for collagen production because they provide the cofactors.

Think of collagen synthesis like a construction site. The amino acids (proline, glycine, hydroxyproline) are the bricks. Collagen itself is the wall. But you can't build the wall without the workers and the mortar. That’s where plant-based nutrients come in.

Vitamin C: The Essential Catalyst

Vitamin C is perhaps the most important nutrient for collagen production. It acts as a cofactor for the enzymes prolyl hydroxylase and lysyl hydroxylase, which stabilize the collagen molecule. Without adequate Vitamin C, your body cannot link those amino acid chains together. This is why a symptom of scurvy (extreme Vitamin C deficiency) is the literal "falling apart" of the body’s connective tissues.

To support your body’s natural synthesis, you should consume plenty of:

  • Citrus fruits (lemons, limes, oranges)
  • Strawberries and raspberries
  • Bell peppers (which actually contain more Vitamin C per gram than oranges)
  • Broccoli and kale

For an extra boost, many members of our community use our Vitamin C supplement, which includes citrus bioflavonoids to mimic the way Vitamin C is found in nature.

Zinc and Copper

Copper and zinc are minerals that play a supporting role in collagen formation. Copper activates an enzyme called lysyl oxidase, which is required for collagen cross-linking—the process that gives collagen its strength and resilience. Zinc, meanwhile, is essential for cell turnover and repair.

Excellent food sources for these minerals include:

  • Pumpkin seeds and cashews
  • Lentils and chickpeas
  • Shellfish (oysters are the highest source of zinc)
  • Dark chocolate (in moderation)

Antioxidant-Rich Greens

Chlorophyll, the pigment that gives plants their green color, has been shown in some studies to increase the precursor to collagen (procollagen) in the skin. Leafy greens like spinach, Swiss chard, and bok choy are also packed with antioxidants that protect your existing collagen from "oxidative stress"—the damage caused by environmental toxins and UV rays.

The Role of Digestion in Collagen Absorption

It isn’t enough to just eat collagen-rich foods; your body has to be able to break them down. Proteins are large molecules, and collagen is particularly "tough." In order for your body to use the glycine and proline from that bone broth or chicken skin, your digestive system—specifically your stomach acid and enzymes—must be functioning optimally.

This is why we emphasize gut health as part of our wellness philosophy. If your digestion is sluggish, those expensive organic bone broths might just pass through you without being fully absorbed. One way to support the digestive environment is through the use of Apple Cider Vinegar Gummies. ACV has been traditionally used to support a healthy pH balance in the stomach, which is the first step in protein denaturation and digestion.

Furthermore, hydration is key. Every metabolic process in the body, including the synthesis of new tissue, requires water and electrolytes. If you’re pushing your body hard in the gym or out on the trail, make sure you’re using Hydrate or Die to keep your cellular environment primed for repair.

Collagen Synthesis vs. Collagen Supplementation

There is often a debate about whether it's better to eat collagen-rich foods or take a supplement. The truth is that both have their place. Whole foods like bone broth provide a complex array of minerals and nutrients that supplements can't always replicate. However, supplements have one major advantage: hydrolysis.

Our Collagen Peptides are hydrolyzed, which means the long collagen chains have been broken down into shorter chains called peptides. These peptides are much easier for the body to absorb and transport directly to the tissues that need them most.

In a typical day, you might not have time to simmer bones or eat a bowl of sardines. But you can always put a scoop of peptides in your coffee. By combining a diet rich in collagen precursors (like Vitamin C and leafy greens) with a daily serving of high-quality peptides, you are providing your body with both the "workers" and the "pre-fabricated materials" it needs to maintain its structural integrity.

Habits That Deplete Your Collagen

Even if you’re eating all the right foods, you could be fighting a losing battle if your lifestyle is actively destroying your collagen. Several factors act like "collagen kryptonite," accelerating the breakdown of your body’s connective tissues:

  1. Sugar and Refined Carbs: Sugar interferes with collagen’s ability to repair itself through a process called glycation. This creates "Advanced Glycation Endproducts" (AGEs), which make collagen fibers brittle and prone to breaking.
  2. Excessive Sun Exposure: UV radiation penetrates the dermis and breaks down collagen fibers, leading to premature aging and loss of elasticity.
  3. Smoking: Tobacco smoke reduces the amount of oxygen that reaches your tissues and introduces toxins that directly inhibit collagen synthesis.
  4. Chronic Stress: High cortisol levels can break down collagen into amino acids for energy, literally "eating" your structural tissues during times of high stress.

To counter these factors, we recommend a holistic approach. Protect your skin, manage your stress, and fuel your body with clean energy. Many of our customers find that replacing sugary coffee creamers with our MCT Oil Creamer helps reduce sugar cravings and provides sustained mental clarity, making it easier to stick to a collagen-protective diet.

Integrating Collagen Into Your Active Lifestyle

At BUBS Naturals, we don't just talk about wellness; we live it. Our products are designed to be part of an active, adventurous lifestyle. If you’re training for a marathon, a CrossFit competition, or just trying to stay mobile for your kids, your collagen needs are higher than the average person’s.

During heavy training, your tendons and ligaments are under constant tension. This mechanical stress actually signals the body to produce more collagen, but it can only do so if the raw materials are available. This is why many athletes take Collagen Peptides about 30 to 60 minutes before a workout. The increased blood flow to the joints during exercise helps deliver those peptides right where they’re needed.

We also suggest pairing your collagen with Creatine Monohydrate. While creatine is primarily used for muscle power and ATP production, the combination of strength training and collagen support ensures that as your muscles get stronger, your connective tissues are tough enough to handle the increased load.

The BUBS Difference: Quality and Purpose

When you’re looking at what foods contain a lot of collagen or which supplements to buy, quality is everything. There are a lot of products on the market that use cheap fillers, artificial sweeteners, or low-quality sourcing. That’s not how we do things.

Every batch of our Collagen Peptides is NSF for Sport certified. This means it has been rigorously tested for over 280 banned substances and contaminants. It’s the gold standard for professional athletes and anyone who cares about what goes into their body. Our peptides are unflavored, mix effortlessly in anything, and contain a single ingredient: bovine hide collagen peptides. No BS.

But beyond the science and the testing, there is the mission. We started BUBS Naturals to honor Glen Doherty. Glen was the kind of person who would give you the shirt off his back, and he believed in leaving the world better than he found it. By choosing BUBS, you aren't just supporting your own health; you are supporting the Glen Doherty Memorial Foundation. Our 10% rule is our commitment to giving back to the veteran community, helping them transition into their next great adventure.

FAQ

Can I get enough collagen from a vegan diet? Since collagen is an animal protein, there are no plant-based sources of collagen itself. However, you can support your body’s natural collagen production by eating plenty of Vitamin C-rich fruits, leafy greens, and zinc-heavy seeds. For those who aren't strictly vegan, supplementing with Collagen Peptides is the most effective way to ensure you are getting the specific amino acids (proline, glycine, hydroxyproline) that are difficult to find in plant proteins.

How long does it take to see results from eating collagen-rich foods? Collagen turnover is a slow biological process. While everyone’s body is different, most research suggests that it takes about 4 to 12 weeks of consistent intake to notice changes in skin elasticity, joint comfort, or nail strength. Consistency is the most important factor, which is why we recommend making collagen a daily habit, perhaps by mixing it into your morning coffee using our MCT Oil Creamer.

Is bone broth better than a collagen supplement? Both have unique benefits. Bone broth is a whole food that contains a variety of minerals and marrow-based nutrients. However, a supplement like our Collagen Peptides is hydrolyzed, meaning it is much easier for your body to absorb and use immediately. For the best results, many people choose to enjoy bone broth for its culinary and nutritional depth while using peptides for daily, convenient support.

Does cooking collagen-rich foods destroy the collagen? Actually, the opposite is true for certain sources. Cooking the tough connective tissues in meat or bones (like in bone broth) breaks the collagen down into gelatin, which makes it much more digestible and bioavailable for your body. However, you should still ensure you’re getting plenty of raw or lightly cooked Vitamin C sources, like bell peppers or citrus, because Vitamin C is heat-sensitive and is required to process that collagen.
