Introduction

Every single day, your body performs a quiet, chemical miracle: it produces about one to two grams of a compound so essential for life that without it, your brain and muscles would essentially stall out. That compound is creatine. While many people recognize the name from the labels of tubs in high-end gyms or in the supplement stacks of elite athletes, most don't realize that they are walking, talking creatine factories. In fact, that small daily amount your body synthesizes is roughly the size of one or two jellybeans, yet it serves as the cornerstone for every explosive movement, every heavy lift, and every sharp thought you have.

At BUBS Naturals, we are obsessed with the "why" behind wellness. Our brand was founded to honor the legacy of Glen “BUB” Doherty—a Navy SEAL, an adventurer, and a man who believed in pushing the limits of human potential. To honor that legacy, we prioritize clean, science-backed nutrition that works in harmony with your body’s natural systems. Understanding how your body produces its own energy helps you make better decisions about how to fuel your lifestyle. The question of whether or not creatine is made in the body is just the starting point of a much deeper journey into human bioenergetics.

By the end of this article, you will have a comprehensive understanding of the internal "creatine factory" located in your liver and kidneys. We will explore the specific amino acids required for this process, the role of external diet, and why supplementing with high-quality Creatine Monohydrate can be the bridge between average function and peak performance. Whether you are an elite athlete or someone looking to support healthy aging and cognitive clarity, understanding this internal synthesis is key to optimizing your wellness routine. We’ll also look at how this fits into a broader lifestyle of adventure, supported by our commitment to giving back—donating 10% of our profits to veteran-focused charities.

The Internal Factory: How Creatine Is Synthesized

To answer the central question—is creatine made in the body—we have to look at the liver, the kidneys, and the pancreas. While many people think of creatine as a "muscle thing," its journey actually begins in the visceral organs. This is a multi-step enzymatic process that transforms simple amino acids into a potent energy precursor.

The first step occurs primarily in the kidneys. Here, two amino acids—arginine and glycine—meet. An enzyme called L-arginine:glycine amidinotransferase (AGAT) facilitates a reaction where an amidine group from arginine is transferred to glycine. This produces a precursor called guanidinoacetate (GAA) and a byproduct called ornithine. This first stage is the rate-limiting step, meaning the body carefully controls how much GAA is produced based on how much creatine it thinks it needs.

The second step takes place mostly in the liver. The GAA travels through the bloodstream to the liver, where another enzyme, guanidinoacetate N-methyltransferase (GAMT), takes over. Using a derivative of the amino acid methionine (specifically S-adenosyl-L-methionine), the liver adds a methyl group to the GAA. The result of this chemical "handshake" is creatine. Once synthesized, this freshly minted creatine is released into the blood, where it travels to its final destinations: the skeletal muscles, the heart, and the brain.

It is a fascinatingly efficient system. We see this reflect our own "no-BS" approach to health—the body uses exactly what it needs, from the simplest building blocks, to create something powerful. However, because this process is so complex and relies on several different organs and amino acids, it can be influenced by your overall health, your protein intake, and even your genetics. If any part of this chain is lacking, the body’s ability to maintain its energy "buffer" can be compromised.

Where Creatine Lives: Storage and Distribution

Once the liver and kidneys have done their job, the creatine doesn't just hang around in the blood. It needs to get inside the cells where the real work happens. This is achieved through a specialized transport system known as the sodium- and chloride-dependent creatine transporter (CRT). Think of this like a high-security gate that specifically allows creatine to enter cells with high energy demands.

About 95% of your body’s creatine is stored in your skeletal muscles. Within those muscles, it exists in two forms: free creatine and phosphocreatine. Phosphocreatine is the "charged" version—it has a phosphate group attached to it, ready to be sacrificed at a moment's notice to create energy. The remaining 5% is distributed in the brain, the heart, and even the testes. These are all organs that require rapid, intense bursts of energy to function correctly.

The typical person has a "storage tank" that is only about 60% to 80% full. This baseline is maintained by that one to two grams of internal production plus whatever you get from your diet. For someone living a sedentary life, this might be enough. But for the BUBS community—the people out there hiking, lifting, surfing, and serving—those tanks can run low quickly. This is where the concept of "saturation" comes in. By using a supplement like our Creatine Monohydrate, we can top off those tanks to 100%, ensuring that when the moment of high-intensity effort arrives, the body is fully prepared.

The Phosphagen System: Powering Your Adventure

To truly appreciate why the body goes through the trouble of making creatine, we have to talk about ATP (Adenosine Triphosphate). ATP is the universal energy currency of life. Every time you blink, think, or sprint, your body is "spending" ATP. When an ATP molecule is used for energy, it loses one of its three phosphate groups and becomes ADP (Adenosine Diphosphate).

Here is the problem: your muscles only store enough ATP to power about two to three seconds of maximum effort. After that, you're out of cash. This is where the phosphagen system, fueled by creatine, saves the day. Phosphocreatine (the stored version of creatine) jumps in and "donates" its phosphate group to the ADP, turning it back into ATP almost instantaneously. This allows you to maintain peak power for another five to ten seconds.

This chemical reaction is reversible and happens in the blink of an eye, catalyzed by an enzyme called creatine kinase. When you are at rest, your body uses energy from your metabolism to "recharge" the creatine, turning it back into phosphocreatine. It is a beautiful, self-sustaining loop. By supporting this system, we support the body's natural ability to handle stress and physical demands. Whether you are using Hydrate or Die to stay balanced during a grueling workout or relying on your internal creatine stores for a final sprint, your bioenergetics are always working to keep you in the game.

Diet vs. Synthesis: The Role of Food

While our bodies are capable of making creatine from scratch, they also expect us to chip in through our diet. In an omnivorous diet, we typically get about one gram of creatine per day from food sources. The richest sources are red meat (beef, bison, lamb) and seafood (salmon, herring, tuna).

When you eat a steak, the creatine is absorbed in your intestines and transported to your muscles just like the creatine your liver makes. This dietary intake eases the burden on your internal factory. If you provide the body with pre-made creatine, it can divert its amino acids (like arginine and glycine) to other important tasks, such as protein synthesis or immune support. This is a great example of how we can use nutrition to optimize our internal resources.

However, this presents a unique challenge for vegetarians and vegans. Since creatine is found almost exclusively in animal tissues, those on plant-based diets often have significantly lower levels of stored muscle creatine. Their bodies have to work overtime to synthesize enough to meet baseline needs, and even then, they rarely reach the levels of meat-eaters. For this reason, many people following a plant-based lifestyle find that supplementing with Creatine Monohydrate provides a noticeable boost in both physical energy and mental clarity. It’s a clean, simple way to fill a nutritional gap without compromising dietary choices.

The Performance Gap: Why We Supplement

If the body makes it and we can eat it, why do we need a tub of it on our kitchen counter? The answer lies in the "Performance Gap." To achieve the levels of creatine saturation shown in clinical studies to improve strength and power, you would need to eat roughly two to three pounds of raw steak every single day. For most of us, that is neither practical, affordable, nor particularly healthy.

Supplementation allows us to reach "maximal saturation" safely and efficiently. By adding a five-gram scoop of high-quality, single-ingredient powder to your routine, you are providing your body with significantly more creatine than it could ever produce on its own. This doesn't replace your body's natural production; rather, it augments it.

When your muscles are fully saturated, you may notice that you can squeeze out one or two more repetitions during a heavy set of squats, or that your recovery time between sprints is slightly shorter. These small gains accumulate over time into significant improvements in muscle mass and performance. We recommend our Creatine Monohydrate because it is the most researched form of the supplement, it's NSF for Sport certified, and it mixes effortlessly into your favorite beverage—no clumping, no grit, just pure fuel.

A Day in the Life: Integrating BUBS Into Your Routine

To see how all of this fits together, let’s look at how a typical day of adventure and wellness might look for someone in the BUBS community. We believe that wellness isn't a chore; it's a way to prepare for the things you love to do.

Your morning might start with a focus on mental clarity and sustained energy. Many of our team members start their day by adding a scoop of MCT Oil Creamer to their morning coffee. The medium-chain triglycerides provide a quick source of ketone energy for the brain, while the creamy texture makes the ritual enjoyable. This sets a foundation of focus before you even hit the gym or the trail.

As you head into your mid-day workout, hydration is the priority. We know that even a 2% drop in hydration can lead to a significant decrease in performance. Mixing a packet of Hydrate or Die - Lemon into your water bottle ensures that your cells have the electrolytes they need to keep your muscles firing and your internal creatine transporters working efficiently.

After the workout, the focus shifts to recovery and rebuilding. This is the perfect time to mix a scoop of Collagen Peptides with your post-workout shake or even just a glass of water. While the collagen supports your joints, skin, and connective tissues, this is also when you should take your Creatine Monohydrate. Research suggests that taking creatine after exercise, especially when paired with a little bit of protein or carbohydrates, may help with absorption and muscle retention.

Finally, as the day winds down, you might support your immune system and digestion with our Vitamin C or a couple of Apple Cider Vinegar Gummies. By the time you go to sleep, you’ve supported your body’s natural processes from every angle, all while knowing that your purchase is helping support the veteran community through our 10% pledge.

Creatine for the Brain: More Than Just Muscle

While the sports world has claimed creatine as its own, the scientific community is increasingly looking at its role in the brain. Because the brain is an incredibly "expensive" organ in terms of energy consumption—using about 20% of your total daily calories—it relies heavily on the ATP/phosphocreatine system.

Is creatine made in the brain as well? Yes, in small amounts. Some brain cells are capable of local synthesis, but the majority of the brain’s creatine still comes from the blood. Studies have shown that during times of high mental stress, sleep deprivation, or complex task execution, brain creatine levels can drop. Supplementation has been shown in some research to support short-term memory and reasoning, particularly in older adults or those who are stressed.

This fits perfectly with our mission of supporting an active, purposeful life. You don't just want your body to be strong; you want your mind to be sharp. Whether you are navigating a difficult mountain trail or a complex business negotiation, having your internal energy stores topped off gives you a cognitive "buffer" that helps you stay calm and focused under pressure. It is another way that simple, clean ingredients like our Creatine Monohydrate can make a tangible difference in your daily life.

Healthy Aging and Longevity

One of the most exciting areas of research regarding creatine is its role in healthy aging. As we age, we naturally begin to lose muscle mass and strength—a process known as sarcopenia. This loss of muscle can lead to decreased mobility, a higher risk of falls, and a lower quality of life.

By supplementing with creatine and engaging in regular resistance training, older adults can better support their muscle health. Creatine doesn't just provide energy; it also influences cell signaling pathways that aid in muscle repair and growth. It helps the body maintain its "machinery" as the years go by. When we pair this with the joint-supporting benefits of Collagen Peptides, we create a powerful foundation for longevity.

We often talk about "dying with your boots on"—a sentiment that Glen Doherty lived by. We want our community to stay active and adventurous well into their later years. By understanding that your body’s natural production of creatine and collagen may become less efficient over time, you can take proactive steps to supplement those levels. It isn't about fighting nature; it's about giving nature the tools it needs to keep you moving.

Safety, Myths, and the Truth About Creatine

Because creatine is so effective, it has unfortunately been surrounded by myths for decades. You may have heard that it’s a steroid, that it’s hard on the kidneys, or that it causes excessive water retention. Let’s clear the air with the "no-BS" truth.

First, creatine is not a steroid. It is a nitrogenous organic acid, a compound naturally occurring in your body and in the food you eat. It has no relationship to synthetic hormones. Second, for healthy individuals, hundreds of studies have shown that long-term creatine use is safe and does not harm the kidneys or liver. While it can cause a slight increase in "creatinine" (a waste product) in blood tests, this is simply a reflection of having more creatine in your system, not a sign of kidney damage.

Regarding water retention, creatine does pull water into the muscle cells. This is actually a good thing! This "cell volumization" is part of what triggers muscle growth and keeps your muscles hydrated. It may cause a small, temporary increase in body weight, but this is water in the muscles, not fat gain. To help manage your body's fluid balance, we always recommend staying well-hydrated with a product like Hydrate or Die. When you give your body the right balance of electrolytes and pure creatine, you feel stronger and fuller, not bloated.

Choosing the Right Supplement: The BUBS Difference

Not all creatine is created equal. Because the supplement industry can sometimes be a "wild west" of fillers and low-quality sourcing, we decided to do things differently. When we developed our Creatine Monohydrate, we had several non-negotiables.

First, it had to be the monohydrate form. While there are newer, "flashier" versions of creatine like nitrate or HCL, none have the decades of safety and efficacy data that monohydrate possesses. It is the gold standard for a reason. Second, it had to be pure. We don't use "blends," flavors, or artificial sweeteners. It is a single-ingredient product that fits perfectly into our philosophy of simplicity.

Finally, and perhaps most importantly, it had to be NSF Certified for Sport. This is a rigorous third-party testing process that ensures what is on the label is in the bag, and more importantly, that there are no banned substances. This is why professional athletes and high-level operators trust BUBS. When you choose our Creatine Monohydrate, you aren't just buying a supplement; you are investing in a product that respects your body and supports a legacy of giving back.

Maximizing the Benefits: Dosing and Timing

Once you've decided to support your body's natural production with a supplement, the next question is how to take it. There are two main strategies: the loading phase and the maintenance phase.

A loading phase involves taking about 20 grams of creatine per day (divided into four doses) for five to seven days. This is designed to saturate your muscle stores as quickly as possible. After that, you drop down to a maintenance dose of three to five grams per day. This is the "fast track" to seeing results.

Alternatively, you can skip the loading phase and simply take three to five grams per day from the start. Your muscles will still reach full saturation; it will just take about three to four weeks instead of one. For most people, the maintenance approach is easier on the stomach and just as effective in the long run.

In terms of timing, the most important thing is consistency. Whether you mix it into your morning coffee with MCT Oil Creamer or stir it into your post-workout Collagen Peptides, the goal is to keep your "tank" full every single day. Creatine isn't a stimulant like caffeine; it's a structural energy support that works best when it's always available in your system.

The Connection Between Creatine and Collagen

While they serve different primary functions, creatine and collagen are two of the most important "foundational" supplements for an active lifestyle. They actually work together in a unique way within the body. Both are nitrogen-rich compounds that rely on the amino acid glycine for their structure.

By supplementing with both Collagen Peptides and Creatine Monohydrate, you are providing your body with an abundance of glycine. This supports the internal synthesis of even more creatine while simultaneously providing the building blocks for your skin, hair, nails, and joints.

Think of creatine as the fuel for your "engine" (the muscles and brain) and collagen as the "chassis" that holds everything together. You need both to be strong if you want to perform at your best. This holistic approach to nutrition is what we mean when we talk about a life of wellness and purpose. We aren't just looking for a quick fix; we are looking for the clean, natural ways to support the body's magnificent internal architecture.

FAQ

Can I get enough creatine from my body’s natural production alone?
While your body produces about 1–2 grams of creatine daily, this is typically only enough to maintain basic physiological functions. For those who engage in high-intensity exercise, seek to increase muscle mass, or want to maximize cognitive performance, this natural production often falls short of the "saturation" levels needed to see significant benefits. Supplementing with Creatine Monohydrate is a safe and effective way to bridge that gap and ensure your muscle stores are fully optimized.

If my body makes creatine, is it safe to take more?
Yes, creatine is one of the most extensively researched supplements in history, with hundreds of studies confirming its safety in healthy individuals. Taking additional creatine doesn't "shut down" your body’s ability to make its own; rather, it provides an exogenous source that allows your body to reach higher levels of muscle and brain saturation. Always ensure you are using a pure, third-party tested product like our Creatine Monohydrate to avoid unnecessary fillers or contaminants.

Do vegetarians need to worry more about their creatine levels?
Vegetarians and vegans typically have lower levels of stored muscle creatine because the primary dietary sources of the compound are red meat and seafood. Since their bodies must rely entirely on internal synthesis, they often start from a lower baseline than omnivores. Many plant-based athletes find that supplementing with Creatine Monohydrate provides a particularly noticeable boost in strength and mental focus because it fills a significant nutritional gap in their diet.

Does taking creatine cause dehydration?
There is a common misconception that creatine causes dehydration or muscle cramps, but scientific research suggests the opposite. Creatine actually pulls water into your muscle cells, which can help with cellular hydration. However, because your muscles are holding more water, it is important to maintain overall fluid balance. We recommend pairing your creatine routine with plenty of water and electrolytes, such as our Hydrate or Die, to ensure you stay properly hydrated throughout your daily adventures.
