Introduction

In 1832, a French chemist named Michel Eugène Chevreul was examining the chemical constituents of meat when he stumbled upon a nitrogenous organic acid that would eventually revolutionize the world of sports science and metabolic health. He named this discovery "creatine," derived from the Greek word kreas, meaning flesh. For nearly two centuries, this compound remained a subject of academic curiosity until it burst onto the global stage during the 1992 Barcelona Olympics, where world-class sprinters and hurdlers credited their explosive performance to this natural power source. But here is the most fascinating part: you don't actually need to be a gold-medal athlete or even eat a steak to have creatine in your system. In fact, while you are reading this very sentence, your organs are hard at work performing a complex series of enzymatic reactions to manufacture it from scratch.

When people ask, "Do your body produce creatine?" the answer is a resounding yes, but the mechanics of that production are far more sophisticated than most realize. Your body is a high-precision chemical plant, synthesizing roughly one to two grams of creatine every single day. This internal production is the baseline that keeps your cellular "batteries" charged, supporting everything from a simple walk to the corner store to the intense cognitive demands of a high-stakes board meeting. However, for those of us living an active lifestyle—whether that means hitting the gym, chasing kids, or tackling a weekend hike—that baseline production might not be enough to reach peak potential.

The purpose of this article is to pull back the curtain on the internal biology of creatine. We are going to explore the specific organs involved in its synthesis, the amino acids that serve as its building blocks, and why your body’s natural production might need a little help from high-quality supplementation. We will also discuss how our Creatine Monohydrate can fit into a wellness routine that honors the legacy of Glen “BUB” Doherty—a man who lived a life of peak performance, adventure, and service. By the end of this guide, you will understand not just how your body makes creatine, but how you can optimize your stores to support your own pursuit of a life well-lived.

What Exactly is Creatine?

To understand how the body produces this compound, we first need to define what it is. Creatine is often mistaken for a protein or even a steroid, but it is neither. Technically, it is a nitrogenous organic acid, often described as an "amino acid derivative." While it isn't one of the 20 standard amino acids that build muscle tissue, it is constructed from three of them: arginine, glycine, and methionine.

Think of creatine as a specialized energy currency. About 95% of the creatine in your body is stored in your skeletal muscle, while the remaining 5% is distributed between your brain, heart, and testes. Within the muscle, it primarily exists in two forms: free creatine and phosphocreatine. Phosphocreatine is the "charged" version—it carries a high-energy phosphate group that it can donate at a moment's notice to help your cells regenerate energy.

This energy-recycling role is why creatine is so vital. Your cells run on a molecule called Adenosine Triphosphate (ATP). When you move or think, ATP loses a phosphate group and becomes Adenosine Diphosphate (ADP). You can think of ADP as a "dead battery." Phosphocreatine steps in, hands over its phosphate group to the ADP, and instantly turns it back into a "charged" ATP molecule. This happens in fractions of a second, allowing you to maintain high-intensity effort. Without this system, your explosive energy would fizzle out in just a few seconds.

The Internal Factory: How Your Body Produces Creatine

The journey of creatine synthesis is a multi-organ relay race. It doesn't happen in just one spot; instead, it requires the cooperation of the kidneys, the liver, and the pancreas. This process is a testament to the body’s efficiency, utilizing raw materials from your diet and converting them into a high-utility fuel.

Phase One: The Kidney Connection

The synthesis begins in the kidneys. Here, two amino acids—arginine and glycine—meet. An enzyme called L-arginine:glycine amidinotransferase (AGAT) facilitates a reaction between them. The result of this first step is a precursor molecule called guanidinoacetate, or GAA. This is a critical moment in the process because the availability of the AGAT enzyme is often the "bottleneck" or the rate-limiting step in how much creatine your body can produce naturally. Once the kidneys have produced the GAA, it is released into the bloodstream to travel to the next station: the liver.

Phase Two: The Liver’s Final Touch

Once the GAA reaches the liver, it undergoes a process called methylation. This is where the third amino acid, methionine, comes into play—specifically in its form as S-adenosylmethionine (SAMe). An enzyme in the liver called guanidinoacetate N-methyltransferase (GAMT) takes a methyl group from SAMe and attaches it to the GAA. This final chemical tweak transforms the precursor into actual creatine.

Phase Three: Transport and Storage

Now that the liver has finished the "manufacturing," the creatine is once again released into the blood. It doesn't stay in the liver; it needs to get to the tissues that have the highest energy demands. Specialized "creatine transporters" (CrT) act like gatekeepers on the surface of your muscle and brain cells, pulling the creatine inside. Once inside the muscle, about two-thirds of it is converted into phosphocreatine by the enzyme creatine kinase, ready to be used the next time you exert yourself.

This internal production provides about 1 gram of creatine per day. For a sedentary person, this might be enough to get by. But for those of us who follow the BUBS ethos of "doing good and doing it well," we are often pushing our bodies beyond the "standard" requirements. This is why we created our Creatine Monohydrate. By providing 5 grams of pure, NSF for Sport certified creatine, we help you top off those stores that your body’s internal factory might not be able to fully saturate on its own.

The Role of Diet: Exogenous vs. Endogenous

While your body is capable of making creatine from scratch (endogenous production), you also get a significant portion of it from the food you eat (exogenous intake). If you follow an omnivorous diet, you likely consume about 1 gram of creatine daily through sources like red meat, poultry, and fish.

When you eat a steak or a piece of salmon, your digestive system breaks down the protein, and the pre-formed creatine is absorbed into the bloodstream. This reduces the burden on your kidneys and liver to manufacture it from scratch. However, there is a catch. To get the 5 grams of creatine often recommended for optimal performance support, you would need to eat roughly two to three pounds of raw meat every day. Not only is that impractical and expensive, but it also comes with a host of digestive challenges and unwanted caloric intake.

This is especially relevant for our vegetarian and vegan friends. Because creatine is found almost exclusively in animal tissues, those who follow plant-based diets often have significantly lower resting levels of muscle creatine. For these individuals, the body has to work overtime to produce enough from the amino acids arginine, glycine, and methionine found in plant proteins. This is a primary reason why vegetarians often see the most dramatic improvements in strength and cognitive clarity when they begin using a high-quality supplement.

At BUBS Naturals, we believe in keeping things simple. Whether you’re getting your nutrients from a balanced diet or supporting your routine with our Collagen Peptides, the goal is to provide your body with the clean building blocks it needs to thrive.

Why Natural Production Often Falls Short

You might wonder: if my body makes creatine, why do I need more? The answer lies in the concept of "saturation." In most people who do not supplement, muscle creatine stores are only about 60% to 80% full. Your body produces enough to keep the lights on, but not necessarily enough to keep the high-powered floodlights running during a heavy set of squats or a long day of mental focus.

When you supplement with Creatine Monohydrate, you are essentially filling that remaining 20% to 40% of the tank. This "saturation" allows for a larger pool of phosphocreatine to be available. In practical terms, this means you might be able to squeeze out two more reps at the end of a set, or recover thirty seconds faster between sprints.

Furthermore, external factors can drain your natural stores faster than your body can replenish them. High-intensity exercise, chronic stress, and even lack of sleep can increase the demand for ATP, and by extension, the demand for creatine. If your body’s production line is already running at max capacity, you’ll start to feel the effects of that "energy debt"—which manifests as physical fatigue and brain fog.

Beyond the Muscle: Creatine and Brain Health

While we often talk about creatine in the context of the gym, we cannot ignore the organ that uses the most energy in the entire body: the brain. Although it only accounts for about 2% of your body weight, the brain consumes roughly 20% of your total energy. Because the brain relies on the same ATP-PCr system as your muscles, it also requires a steady supply of creatine to function.

Recent research has shown that while the brain can produce some of its own creatine, it also relies on taking it up from the blood. During times of "metabolic stress"—such as periods of sleep deprivation or intense cognitive tasks—supplemental creatine has been shown to support memory, reasoning, and mental processing speed.

We often talk about the importance of "mental fitness" at BUBS. Whether you’re a tactical athlete or a weekend warrior, your ability to make sharp decisions under pressure is just as important as your physical strength. Integrating a daily scoop of Creatine Monohydrate into your morning ritual—perhaps alongside a cup of coffee boosted with our MCT Oil Creamer—can be a game-changer for both your body and your mind.

The BUBS Mission: Clean Ingredients and Giving Back

At the heart of BUBS Naturals is a commitment that goes beyond the bottom line. Our company was founded to honor the legacy of Glen “BUB” Doherty, a Navy SEAL, adventurer, and friend who was lost in Benghazi, Libya, in 2012. Glen lived his life with a "no-BS" attitude, and we carry that philosophy into every product we make.

When we developed our Creatine Monohydrate, we knew it had to meet the highest standards. That means no fillers, no additives, and rigorous third-party testing. We are proud that our creatine is NSF for Sport certified, ensuring that it is free from banned substances and safe for athletes at every level of competition.

But the mission doesn't stop with clean ingredients. We are dedicated to the 10% Rule: we donate 10% of all our profits to veteran-focused charities, primarily through the Glen Doherty Memorial Foundation. This foundation helps special operations veterans and their families transition to civilian life through traditional and non-traditional education. When you choose BUBS, you aren't just supporting your own wellness; you’re helping us give back to the community that Glen loved so much.

How to Optimize Your Creatine Levels

If you’re ready to move beyond your body’s baseline production, consistency is the key. You don't need fancy "loading phases" or complicated timing strategies. The goal is simply to reach and maintain muscle saturation.

The Maintenance Protocol

For most people, a daily dose of 5 grams (about one scoop) is the "sweet spot." Taking it every day—including rest days—ensures that your levels stay topped off. Some people prefer a "loading phase" of 20 grams a day for the first week to see results faster, but research shows that taking 5 grams daily will get you to the same place within 3 to 4 weeks without the potential for digestive upset.

Mixing and Stacking

One of the best things about our Creatine Monohydrate is how easily it mixes. It is unflavored and dissolves completely, making it the perfect addition to any drink.

A "Day in the Life" of a BUBS routine might look like this:

• Morning: A scoop of MCT Oil Creamer in your coffee for sustained mental clarity.
• Pre-Workout: A serving of Hydrate or Die to ensure your electrolyte levels are primed for performance.
• Post-Workout: A shake containing one scoop of Creatine Monohydrate and a scoop of Collagen Peptides to support muscle recovery and joint health.
• Daily Maintenance: A couple of Apple Cider Vinegar Gummies for digestive support and a Vitamin C capsule to keep your immune system strong and support natural collagen formation.

Addressing the Common Myths

Despite being one of the most researched supplements in the world, creatine is still surrounded by a fair amount of misinformation. When we talk to people about why we advocate for Creatine Monohydrate, we often have to clear the air on a few common myths.

Myth 1: It’s Bad for Your Kidneys

Because the body produces "creatinine" (a waste product) from creatine, and doctors use creatinine levels to measure kidney function, some people mistakenly believe that taking creatine damages the kidneys. However, hundreds of studies have shown that for healthy individuals, long-term creatine use is perfectly safe. If you have pre-existing kidney disease, you should always consult your doctor, but for the average healthy adult, there is no evidence of harm.

Myth 2: It Makes You Gain Fat

Creatine can cause some initial weight gain, but it isn't fat. Because creatine is "osmotic," it draws water into the muscle cells. This is actually a good thing—it's called "cellular hydration" and can support protein synthesis. If the scale goes up a pound or two in the first week, it’s just water being stored where you want it: inside your muscles, making them look fuller and helping them perform better.

Myth 3: It’s Only for Bodybuilders

As we’ve discussed, creatine supports the brain, helps with age-related muscle loss (sarcopenia), and assists in recovery for all types of activity. Whether you’re a runner, a yogi, or a busy parent, the energy-recycling benefits of Creatine Monohydrate are universal.

Creatine and the Aging Process

As we get older, our bodies undergo changes that can make staying active more challenging. One of the most significant shifts is the gradual loss of muscle mass and strength, a condition known as sarcopenia. While your body continues to produce creatine as you age, the efficiency of your muscle cells in using that creatine can decrease.

Research has shown that combining creatine supplementation with regular resistance training is one of the most effective ways for older adults to maintain their independence and physical function. It isn't just about looking good at the beach; it’s about having the strength to carry groceries, play with grandkids, and prevent falls.

Furthermore, post-menopausal women may find creatine particularly beneficial. The decline in estrogen can impact muscle and bone health, and emerging studies suggest that creatine may help support bone mineral density and muscle quality during this transition. By supplementing with Creatine Monohydrate, you are providing your body with a low-impact, high-reward tool to support your wellness journey well into your later years.

The Science of Performance and Recovery

The mechanics of how creatine supports performance are rooted in the rate of ATP resynthesis. During high-intensity exercise—like a 40-yard dash or a heavy set of overhead presses—your muscles burn through their available ATP in about 2 to 3 seconds. The phosphocreatine system then takes over, providing energy for another 6 to 8 seconds.

By saturating your muscles with Creatine Monohydrate, you are extending that window of peak power. But the benefits don't stop when the workout ends. There is growing evidence that creatine helps with recovery by reducing muscle cell damage and inflammation. It also appears to enhance the "loading" of glycogen into the muscles. When you take creatine alongside a post-workout meal, your muscles are better able to soak up the carbohydrates they need to refuel for tomorrow's adventure.

To further support this recovery process, we recommend pairing your creatine with our Collagen Peptides. While creatine handles the energy and muscle side of the equation, collagen provides the amino acids necessary to support the connective tissues—tendons, ligaments, and joints—that take a beating during hard training. Together, they form a powerful foundation for a resilient body.

Why Quality Matters: The NSF for Sport Advantage

In the world of supplements, not all products are created equal. Because the FDA does not regulate supplements with the same rigor as pharmaceuticals, it is up to the brand to prove their quality. Many cheaper creatine products on the market are sourced from facilities with poor quality control, leading to potential contamination with heavy metals or banned substances.

At BUBS Naturals, we refuse to cut corners. Our Creatine Monohydrate is NSF for Sport certified. This is the gold standard in the industry. It means that every batch is tested by an independent third party to ensure that what is on the label is exactly what is in the tub—and nothing else. This is why professional athletes, tactical operators, and health-conscious individuals trust BUBS. We provide the peace of mind that allows you to focus on your training and your life, knowing your supplements are as clean as they are effective.

Building Your Adventure-Ready Routine

Wellness isn't about one "magic pill." It's about the cumulative effect of small, consistent choices. Your body’s natural production of creatine is a great start, but it’s just the beginning. By understanding the biology of how you produce and use this compound, you can take control of your energy levels and your physical potential.

We encourage you to think of your supplement routine as a toolkit for your lifestyle. Start with the basics: stay hydrated with Hydrate or Die, keep your joints supple with Collagen Peptides, and fuel your brain with MCT Oil Creamer. Then, add the power of Creatine Monohydrate to ensure your "batteries" are always fully charged.

This holistic approach to wellness is what Glen Doherty lived by. He wasn't just a soldier; he was a skier, a surfer, a pilot, and a lifelong learner. He knew that to get the most out of life, you had to take care of the machine that carries you through it. We are honored to provide the products that help you do the same.

Conclusion

Understanding that your body produces creatine is the first step in appreciating the complex biological miracle that is human metabolism. Your kidneys, liver, and pancreas work in a silent, coordinated effort every day to ensure you have the energy to move, breathe, and think. However, as we’ve explored, this natural production is often just enough to cover the basics. For those who seek adventure, strive for better performance, and want to support their long-term health, bridging the gap between natural production and optimal saturation is a logical next step.

By choosing to supplement, you aren't overriding your body's natural functions; you’re supporting them. You’re providing the extra raw materials—the arginine, glycine, and methionine—in their most bioavailable form to ensure your cellular energy cycle never misses a beat. Whether you are aiming for a personal best in the weight room or simply looking to maintain mental sharpness during a long day, the science is clear: higher levels of creatine support better outcomes.

We invite you to experience the BUBS difference. Our Creatine Monohydrate offers you the purest form of this essential compound, backed by our commitment to clean ingredients and our mission to give back. Every scoop is a tribute to a life of purpose and a step toward your own peak performance.

FAQ

1. Does everyone’s body produce the same amount of creatine? While the average person produces about 1 to 2 grams of creatine daily, the exact amount can vary based on several factors. Individuals with more muscle mass naturally require and produce slightly more. Conversely, your body may down-regulate its own production if you consume a very high-meat diet or take supplements, though it ramps back up once you stop. Vegetarians and vegans typically have lower total stores because their dietary intake is minimal, making their body’s internal production the sole source of creatine unless they supplement.

2. Is it better to take creatine at a certain time of day? Consistency is much more important than timing. Because the goal of supplementation is to keep your muscle stores fully saturated, the most important thing is to take your Creatine Monohydrate every single day. Some people prefer taking it post-workout with a meal to take advantage of the insulin spike, which may help with uptake, while others mix it into their morning coffee with MCT Oil Creamer. Find a time that fits your schedule and stick to it.

3. If my body already makes creatine, will a supplement make me feel "jittery" like caffeine? No, creatine is not a stimulant. It does not affect your central nervous system in the way that caffeine or pre-workout stimulants do. Instead, it works at the cellular level to help your body manage its energy currency (ATP). You won't feel a "rush" immediately after taking it; rather, you’ll notice that you have more endurance during high-intensity efforts and a generally higher ceiling for physical and mental work over time.

4. Can I get enough creatine naturally if I eat a lot of red meat? While you can certainly increase your levels by eating red meat and fish, it is very difficult to reach the 5-gram daily "saturation" level through food alone. You would need to consume roughly 2 to 3 pounds of meat per day to match the dose found in one scoop of Creatine Monohydrate. For most people, supplementation is a much more practical, cost-effective, and digestion-friendly way to ensure they are getting the full benefits of this compound.
