Introduction

At age 20, the clock starts ticking on your body’s internal scaffolding. It sounds like a plot point from a science fiction novel, but it is a biological reality: starting in our early twenties, our natural collagen production begins to decline by about 1% every single year. By the time we hit our 40s or 50s, that loss accelerates, often manifesting as stiff joints, less resilient skin, and a slower recovery after a long day on the trails or in the gym. For those of us living the BUBS Naturals lifestyle—one defined by adventure, movement, and a commitment to doing good—maintaining that structural integrity is essential.

We founded BUBS Naturals to honor the legacy of Glen “BUB” Doherty, a hero, Navy SEAL, and adventurer who believed in living life to the fullest. Our mission is to provide clean, functional, and science-backed supplements that support your journey, whatever it may be. While our Collagen Peptides are a cornerstone for many in their wellness routine, we believe in a "no-BS" approach to health. That means being transparent about who should use our products and, just as importantly, who should approach them with caution.

The purpose of this article is to provide an authoritative look at collagen safety. While it is one of the most widely used and beneficial supplements on the market, it isn't for everyone. We will explore the specific groups of people who might need to avoid collagen, the nuances of medication interactions, and how to identify high-quality supplements that won't compromise your health. By the end of this post, you will understand the biology of collagen, the potential risks for certain individuals, and how to safely integrate supplements into an active lifestyle.

Wellness is not a one-size-fits-all endeavor. Whether you are a marathon runner, a weekend hiker, or someone simply looking to support your body as you age, understanding the "why" behind your supplements is the first step toward true vitality. We aren't just here to sell you a tub of powder; we’re here to ensure you have the knowledge to use it effectively and safely. Together, let’s dive into the science of collagen and determine if it’s the right fit for your unique wellness journey.

Understanding Collagen and Its Role in the Body

To understand who should not take collagen, we first have to understand what it actually is. Collagen is the most abundant protein in the human body, making up roughly one-third of our total protein composition. Think of it as the "glue" that holds everything together. It provides the structural framework for your skin, hair, nails, bones, ligaments, and tendons. Without it, our bodies would literally lose their shape and stability.

There are at least 28 different types of collagen, but the vast majority of the collagen in your body—about 90%—is Type I. This type is incredibly strong and provides the tensile strength needed for skin and bones. Type III is another major player, often found alongside Type I in the skin, blood vessels, and internal organs. When you look at our Collagen Peptides, you’re getting a high-quality blend of Types I and III, which are specifically chosen to support the tissues most impacted by an active, adventurous lifestyle.

Biochemically, collagen is made up of amino acids, primarily glycine, proline, and hydroxyproline. These amino acids twist together to form a triple-helix structure. Your body naturally synthesizes these proteins using the nutrients you consume through food. However, this synthesis is a complex process that requires cofactors like vitamin C. This is why we often recommend pairing your protein intake with our Vitamin C supplement to support the body’s natural collagen formation.

As we age, our fibroblasts—the cells responsible for producing collagen—become less efficient. External factors like UV exposure, smoking, and high sugar consumption can further damage existing collagen fibers through a process called glycation. This leads to the classic signs of aging: wrinkles, sagging skin, and joint discomfort. Supplementation aims to provide the body with the specific building blocks (peptides) it needs to support its own repair and maintenance processes. Because these peptides are "hydrolyzed," they are broken down into smaller, easily absorbable pieces that can circulate through the bloodstream to the areas that need them most.

Who Cannot Take Collagen? Essential Considerations

While collagen is generally considered safe and well-tolerated, there are several groups of people who should exercise caution or avoid supplementation altogether. Because we prioritize your health and transparency, it is important to address these contraindications clearly.

Individuals with Specific Food Allergies

One of the most immediate reasons someone might need to avoid certain collagen supplements is a food allergy. Collagen is always animal-derived; there is no such thing as a "vegan" collagen that is biologically identical to human collagen (though there are vegan "boosters"). Most supplements are sourced from bovine (cow), marine (fish), porcine (pig), or avian (chicken) sources.

If you have a known allergy to fish or shellfish, you must avoid marine collagen. Allergic reactions can range from mild hives and itching to severe anaphylaxis. At BUBS Naturals, our primary Collagen Peptides are sourced from grass-fed, pasture-raised bovine hide. This makes them a safe alternative for those with fish allergies, but those with a rare beef allergy (such as those caused by Lone Star tick bites, known as Alpha-gal syndrome) would need to avoid bovine sources.

People with Kidney Health Concerns

Because collagen is a protein, it must be processed by the kidneys. For the average healthy adult, a high-protein diet or the addition of collagen peptides is perfectly fine. However, individuals with pre-existing kidney disease or compromised renal function must be very careful with their total protein intake.

When the body breaks down protein, it creates nitrogenous waste products that the kidneys must filter out. In someone with chronic kidney disease (CKD), the kidneys are already struggling to keep up. Adding a concentrated source of protein like collagen could potentially place unnecessary strain on the organs. If you have been advised to follow a low-protein diet for kidney health, it is essential to consult your nephrologist before adding any protein supplement to your routine.

Individuals Prone to Kidney Stones

Some research suggests a potential link between collagen supplementation and certain types of kidney stones, specifically calcium oxalate stones. Collagen contains the amino acid hydroxyproline, which the body can convert into oxalate. If you are a "chronic stone former" or have a history of high oxalate levels in your urine, you should discuss collagen use with your doctor. While the risk for most people is low, those with a specific predisposition may need to limit their intake or ensure they are staying exceptionally hydrated. To help with that, we always suggest keeping our Hydrate or Die - Lemon electrolyte drink on hand to support fluid balance and kidney function.

Medications and Potential Interactions

For many of us, supplements are just one part of a broader health regimen that may include prescription medications. While collagen is a food-based supplement, its concentrated nature means it can occasionally interact with how certain drugs are metabolized or how they function in the body.

Blood Thinners (Warfarin/Coumadin)

One area of caution involves blood-thinning medications. Collagen is a vital component of the blood vessel walls and plays a natural role in the body’s clotting process. While there isn't extensive data showing that oral collagen supplements directly interfere with Warfarin, some healthcare providers suggest caution. Because these medications require precise dosing based on the body's clotting factors, any supplement that affects the structural components of the circulatory system should be cleared by a physician.

Thyroid Medications

Many medications, particularly those for thyroid health like Levothyroxine, are highly sensitive to the presence of other substances in the gut. Taking these medications at the same time as a protein-rich supplement like collagen can potentially interfere with their absorption. This doesn't mean you cannot take collagen; it simply means you need to be strategic with your timing. Most pharmacists recommend waiting at least two to four hours between taking thyroid medication and consuming any supplements or food to ensure maximum efficacy.

Beta-Blockers

Some research indicates that high-protein diets can alter the absorption rate of certain beta-blockers, such as Propranolol. Since collagen is a concentrated protein source, it could potentially affect how quickly the medication enters your system. If you are taking medication for heart rate or blood pressure, it is always wise to monitor your readings when starting a new supplement and to keep your doctor informed.

We believe that being "adventure-ready" means having all your systems working in harmony. If you’re using our Collagen Peptides to support your joints after a long bike ride, just ensure that your timing aligns with any necessary medications so you can get the full benefit of both.

Collagen and Special Groups: Pregnancy and Nursing

Pregnancy and breastfeeding are times when women are often extra cautious about what they put into their bodies. During these stages, the body actually has an increased demand for protein to support the growing baby and the production of milk. Many women find that collagen helps support their skin elasticity and joint comfort during the physical changes of pregnancy.

However, the scientific community is often slow to conduct rigorous trials on pregnant and nursing women for ethical reasons. This means that while there is no evidence suggesting collagen is harmful, there isn't a mountain of "pregnancy-safe" clinical trials either.

The biggest risk during pregnancy isn't usually the collagen itself—which is essentially just amino acids—but rather the additives found in many commercial brands. Some collagen powders are loaded with artificial sweeteners, heavy metals (if not properly tested), or "bonus" herbs that may not be safe for a developing fetus.

This is where our "no-BS" commitment comes in. Our Collagen Peptides are NSF for Sport certified, meaning they undergo rigorous third-party testing for purity and contaminants. For a pregnant or nursing mother, this certification provides a level of peace of mind that the product contains exactly what is on the label and nothing else. Even so, we always recommend that expecting or nursing mothers show the label to their OB-GYN or midwife before starting any new supplement.

The Impact of Additives and Fillers

When people ask, "Who cannot take collagen?" the answer is often less about the collagen protein and more about the "extra" ingredients manufacturers put in the tub. The supplement industry is unfortunately filled with products that use fillers to cut costs or additives to mask poor-quality sourcing.

Biotin and Lab Interference

Many collagen supplements are marketed for "hair, skin, and nails" and include high doses of Biotin (Vitamin B7). While Biotin is generally safe, high doses can significantly interfere with certain laboratory tests. Most notably, it can cause false readings in thyroid function tests and even troponin tests used to diagnose heart attacks. If you are taking a collagen supplement with added Biotin, you must stop taking it several days before any blood work to ensure accurate results.

Artificial Sweeteners and Gut Health

For those with sensitive digestive systems or conditions like Irritable Bowel Syndrome (IBS), the artificial sweeteners (like sucralose or aspartame) and sugar alcohols (like erythritol or xylitol) found in many flavored collagen products can cause significant bloating, gas, and distress.

At BUBS, we keep it simple. Our collagen is unflavored and contains one ingredient: bovine collagen peptides. This makes it much easier on the gut. If you want a bit of flavor and a boost of healthy fats without the artificial junk, we recommend mixing it with our MCT Oil Creamer. It’s a clean, creamy way to get sustained energy and your collagen fix in one go.

Heavy Metals and Purity

Collagen is sourced from animal tissues, which can sometimes accumulate heavy metals like lead or arsenic from the environment. People with compromised immune systems or those looking to minimize their toxic load should be wary of any supplement that does not provide third-party testing results. We take this seriously; BUBS Naturals ensures that every batch is tested so you can focus on the adventure ahead without worrying about what’s in your scoop.

Lifestyle Factors That Degrade Collagen

Supplementation is a powerful tool, but it is only one part of the equation. We believe in supporting the body from all angles. If you are taking Collagen Peptides but engaging in lifestyle habits that actively destroy your natural collagen, you’re essentially fighting an uphill battle.

The Damage of UV Exposure

Sunlight is the number one external cause of collagen degradation. UV rays penetrate the skin and break down the collagen fibers in the dermis, leading to premature aging. While we love being outdoors—whether it’s surfing, hiking, or training—protection is key. Use sunscreen and wear protective clothing to preserve the collagen your body is working so hard to build.

Smoking and Alcohol

Smoking is essentially a "collagen killer." It reduces the amount of oxygen reaching your tissues and triggers enzymes that break down the skin’s structural proteins. Similarly, excessive alcohol consumption can dehydrate the body and increase inflammation, both of which interfere with the body’s ability to repair itself. If you’re serious about your longevity and vitality, cutting back on these habits is the most effective thing you can do alongside supplementation.

High Sugar Intake

A diet high in refined sugars leads to the formation of Advanced Glycation End-products (AGEs). These molecules bond to collagen fibers, making them stiff and brittle. This is why a balanced diet is so critical. To help manage cravings for sugary treats while supporting your digestion, many of our community members use Apple Cider Vinegar Gummies as a daily wellness ritual. They are a much cleaner way to satisfy a sweet tooth while doing something good for your gut.

How to Choose a Clean Collagen Supplement

If you’ve determined that you are not in one of the "avoid" categories and are ready to support your body’s structural health, the next step is choosing the right product. In a crowded market, how do you spot a "no-BS" supplement?

1. Look for Third-Party Certification: As mentioned, certifications like NSF for Sport are the gold standard. They ensure the product is free from banned substances and contaminants.
2. Check the Sourcing: High-quality collagen should come from grass-fed, pasture-raised animals. This ensures a better nutrient profile and a more ethical, sustainable product.
3. Single Ingredient is Best: Avoid long lists of additives, flavors, and preservatives. You want the protein, not the filler.
4. Hydrolyzed for Absorption: Ensure the label says "hydrolyzed" or "collagen peptides." This means the protein has been broken down into a form your body can actually use.

Our Collagen Peptides meet all of these criteria. We don't believe in cutting corners because we know our customers—people like you—are out there pushing their limits. You deserve a supplement that works as hard as you do.

Natural Ways to Support Collagen Synthesis

For those who may not be able to take collagen supplements due to the reasons discussed above, or for those who want to maximize their results, focusing on the body’s natural production is key. Your body is a remarkable machine, and with the right raw materials, it can do a lot of the heavy lifting.

Focus on Vitamin C

Vitamin C is a mandatory cofactor for collagen synthesis. Without it, the body cannot cross-link the amino acids to form the triple helix. Incorporating plenty of citrus fruits, bell peppers, and leafy greens is essential. If you’re on the go, our Vitamin C provides a concentrated dose of antioxidant support to keep your natural production huming.

Adequate Protein Intake

Collagen is made from amino acids, which are found in all protein sources. Ensuring you eat enough high-quality protein from eggs, poultry, beans, and fish provides the building blocks for collagen. For athletes looking to support muscle strength alongside their joint health, adding Creatine Monohydrate to your routine can further support your training goals and overall body composition.

Mineral Support

Minerals like zinc and copper also play roles in the enzymatic reactions that create collagen. Pumpkin seeds, cashews, and lentils are great dietary sources. By maintaining a diverse, nutrient-dense diet, you provide your body with the entire toolkit it needs for maintenance and repair.

The BUBS Difference: Legacy and Quality

When you choose a supplement, you aren't just buying a product; you’re supporting a philosophy. At BUBS Naturals, our philosophy is rooted in the "10% Rule." We donate 10% of all profits to veteran-focused charities, specifically the Glen Doherty Memorial Foundation.

Whether that means conquering a mountain peak or simply being able to play with your grandkids without joint pain, we are committed to providing the clean, functional fuel you need. We believe in simplicity—one scoop, mixed into your morning coffee or post-workout shake, to help you feel the difference.

If you’ve walked through this guide and feel confident that collagen is right for you, we invite you to experience the purity of our Collagen Peptides. It is more than just a supplement; it’s a commitment to your long-term wellness and a tribute to a life well-lived.

Conclusion

Understanding who cannot take collagen is an essential part of being an informed and health-conscious individual. While collagen offers incredible support for skin elasticity, joint health, and structural integrity, it is not a universal solution. We’ve explored how allergies to specific animal sources, kidney health concerns, and potential medication interactions can necessitate a more cautious approach. We also highlighted how additives like Biotin and artificial sweeteners can complicate the picture for many users.

The common thread in all of this is the importance of quality and transparency. By choosing supplements that are third-party tested and free from unnecessary fillers, you eliminate many of the risks associated with supplementation. Whether you are supporting your body through natural diet and lifestyle changes or looking to enhance your routine with our Collagen Peptides, the goal remains the same: a life of vitality, adventure, and purpose.

Remember to protect your collagen from the outside by managing UV exposure and from the inside by maintaining a healthy, low-sugar diet. Supplement your journey with intention, stay hydrated with Hydrate or Die - Mixed Berry, and always consult with your healthcare provider if you have underlying conditions or are taking prescription medications.

At BUBS Naturals, we are proud to be a part of your wellness story. Our dedication to clean ingredients and the legacy of Glen “BUB” Doherty ensures that every product we offer is designed to help you live your best life.

FAQ

1. Is it safe to take collagen if I have a fish allergy? It depends on the source of the collagen. Marine collagen is derived from fish and should be strictly avoided by anyone with a fish or shellfish allergy. However, bovine-sourced collagen, such as our Collagen Peptides, is derived from cow hides and is generally safe for those with fish allergies. Always check the label to ensure no cross-contamination or hidden ingredients are present.

2. Can collagen supplements cause kidney stones? For most people, the answer is no. However, collagen contains hydroxyproline, which the body can convert into oxalates. If you have a history of calcium oxalate kidney stones, you should consult your doctor before starting collagen. Staying well-hydrated is also crucial for kidney health, and using a clean electrolyte like Hydrate or Die - Lemon can help support proper fluid balance.

3. Does collagen interact with thyroid medication? Collagen itself does not have a direct chemical interaction with thyroid meds, but because it is a protein, it can slow down or interfere with the absorption of medications like Levothyroxine if taken at the same time. To be safe, it is recommended to take your thyroid medication on an empty stomach and wait at least two to four hours before consuming collagen or other protein-rich foods.

4. Can I take collagen if I am pregnant or nursing? While collagen is essentially just amino acids and is generally considered safe, there is limited clinical research on its use specifically during pregnancy and breastfeeding. The primary concern is often the purity of the supplement and any extra additives. Our Collagen Peptides are NSF for Sport certified, ensuring high purity, but you should always consult your OB-GYN or midwife before adding any new supplement to your routine during this time.
