Introduction

If you have ever stepped foot in a gym or scrolled through a fitness forum, you have undoubtedly heard of creatine. It is perhaps the most researched and widely used supplement in the history of sports nutrition. For decades, athletes, weekend warriors, and those just looking to maintain muscle as they age have turned to this powerhouse for its well-documented ability to support strength and power. However, with popularity comes scrutiny. One of the most persistent questions circulating in the wellness community is: does creatine supplement increase blood pressure? It is a fair question, especially considering how vital cardiovascular health is to a life of adventure and longevity.

At BUBS Naturals, we are built on the legacy of Glen “BUB” Doherty—a Navy SEAL, adventurer, and a man who lived with purpose. We believe in providing you with the cleanest, most effective fuel to support your own mission, whatever that may be. Because our mission involves both wellness and giving back, we take the science behind our supplements seriously. This means cutting through the noise and looking at what the research actually says. We do not do "BS" ingredients, and we do not do "BS" claims. We are here to help you understand your body and how our products, like our Creatine Monohydrate, fit into a healthy, active lifestyle.

In this deep dive, we are going to explore the complex relationship between creatine and blood pressure. We will look at the studies that suggest it might support vascular health, the ones that show no effect at all, and the specific circumstances where caution is warranted. You will learn about how creatine works in the body, the role of ATP, and why the quality of your supplement—and your hydration levels—matters more than you might think. By the end of this article, you will have a clear understanding of whether a Creatine Monohydrate supplement is the right addition to your daily routine and how to use it safely to support your performance goals.

Understanding the Power of Creatine and ATP

Before we can answer the question of blood pressure, we need to understand what creatine is and what it does for the body. Creatine is a naturally occurring compound made from three amino acids: L-arginine, glycine, and L-methionine. Our bodies actually produce about half of the creatine we need in the liver, kidneys, and pancreas. The other half typically comes from our diet, primarily through red meat, seafood, and dairy.

Once inside the body, creatine is converted into phosphocreatine and stored in your muscles. This is where the magic happens. When you engage in high-intensity, short-duration activities—like sprinting for a trailhead or hitting a heavy set of squats—your muscles need energy fast. That energy comes from a molecule called adenosine triphosphate (ATP). The problem is that your body only stores enough ATP for a few seconds of intense effort. When ATP is used, it loses a phosphate molecule and becomes adenosine diphosphate (ADP).

This is where your Creatine Monohydrate comes in. Phosphocreatine "donates" its phosphate group to ADP, quickly turning it back into ATP so your muscles can keep firing. This process is essential for supporting strength, power, and training performance. Because the body can only store so much, supplementing helps saturate these stores, allowing you to push a little harder and recover a little faster.

But creatine is not just for the muscles. Small amounts are also used by the brain and heart to maintain proper function. Because it plays such a fundamental role in cellular energy, it is no surprise that researchers have spent years looking at how it might influence other systems, including the cardiovascular system.

The Research: Does Creatine Impact Blood Pressure?

The relationship between creatine and blood pressure is not a simple "yes" or "no." The research is remarkably nuanced, with different studies yielding different results based on the population being studied, the dosage used, and the duration of the supplementation.

Studies Showing Potential Vascular Support

Interestingly, some research suggests that creatine might actually have a positive effect on blood pressure and vascular health. This is often attributed to creatine’s potential antioxidant properties. By helping to reduce oxidative stress, creatine may support the health and flexibility of blood vessels.

In a 2014 study conducted in Brazil, researchers looked at physically active young men with a median age of 28. After taking 20 grams of creatine for seven days—a common "loading" dose—the participants actually showed a slight drop in blood pressure. The researchers linked this to increased microvascular density and reactivity, essentially meaning the small blood vessels were better able to expand and contract as needed.

More recently, a 2024 study focused on older men with a median age of 71. Given the same 20-gram daily dose for a week, these individuals saw a slight drop in systolic blood pressure (the top number), whereas the placebo group saw no change. While the researchers noted the drop was not "statistically significant," it did suggest that acute creatine use does not automatically lead to hypertension in older populations and may even offer some vascular benefits.

Research Showing No Effect

For the majority of healthy adults, the most common finding in scientific literature is that creatine has zero impact on resting blood pressure. A 2017 study on bodybuilders—who often use higher doses of supplements—showed that while long-term creatine use (up to 15 grams a day) might slightly increase resting heart rate, it did not change blood pressure readings.

Similarly, a 2018 study involving 45 young adults performing high-intensity resistance training found no significant changes in blood pressure or vascular stiffness after supplementing with creatine. This is consistent with the FDA’s general recognition of Creatine Monohydrate as a safe ingredient for healthy adults when used as directed.

When Caution is Necessary

While the outlook is generally positive for healthy individuals, there are specific scenarios where high creatine levels have been linked to an increased risk of hypertension. Some research indicates that persistently high levels of creatine might overstimulate the sympathetic nervous system. Since the sympathetic nervous system helps regulate the narrowing of blood vessels (vasoconstriction), overstimulation could theoretically lead to higher blood pressure.

A long-term study involving over 3,000 adults found that persistently high plasma creatine levels were associated with a 26% higher risk of hypertension in males, though no such link was found in females. Additionally, for those already diagnosed with hypertension, some studies suggest that very high levels of creatine might make blood pressure harder to manage or interfere with the effectiveness of certain therapies.

The Role of the Kidneys and Creatinine

You cannot talk about creatine and blood pressure without talking about the kidneys. One of the reasons people often worry about creatine is that it is naturally broken down into a waste product called creatinine. When you go for a blood test, doctors measure your creatinine levels to see how well your kidneys are filtering your blood.

When you supplement with Creatine Monohydrate, your creatinine levels will likely go up. In a healthy person, this is simply a byproduct of having more creatine in the system and does not indicate kidney damage. However, for people who have pre-existing kidney disease, the kidneys may struggle to filter out this extra creatinine.

Because kidney health and blood pressure are inextricably linked—the kidneys help regulate blood pressure through fluid balance and hormone release—anyone with underlying kidney issues should be extremely cautious. For these individuals, high doses of creatine could potentially strain the kidneys, which in turn could lead to a rise in blood pressure. This is why we always emphasize that while our products are clean and simple, you should always consult with a healthcare professional if you have a pre-existing medical condition.

The Importance of Hydration and Electrolytes

One of the most well-known "side effects" of creatine is that it draws water into the muscle cells. This is actually a good thing for muscle growth and performance—it creates a more anabolic environment and helps your muscles look fuller. However, because that water is being pulled into the muscles, it means there is less water circulating elsewhere in your body.

If you are taking Creatine Monohydrate but not increasing your water intake, you risk becoming dehydrated. Dehydration is a known trigger for increased heart rate and, in some cases, fluctuations in blood pressure.

To support your body's natural functions while supplementing, you need to stay on top of your fluids. But water alone isn't always enough, especially if you’re living the high-adventure lifestyle we love at BUBS. When you sweat, you lose more than just water; you lose essential minerals. That is why we recommend pairing your performance routine with Hydrate or Die - Lemon or Hydrate or Die - Mixed Berry.

Our hydration formula is designed with the optimal ratio of electrolytes to help your body actually absorb the water you drink. By maintaining proper fluid balance, you ensure that the water-drawing effect of creatine supports your muscles without leaving the rest of your system high and dry. Proper hydration is one of the best ways to ensure your blood pressure remains stable during intense training.

The BUBS "No-BS" Approach to Quality

In the world of supplements, quality is everything. Many of the negative side effects people associate with supplements aren't caused by the main ingredient itself, but by fillers, contaminants, or poor manufacturing processes. At BUBS Naturals, we take a "no-BS" approach.

Our Creatine Monohydrate is a single-ingredient product. No sugar, no artificial flavors, and no mystery additives. We use 100% pure micronized creatine monohydrate, which means the particles are smaller and easier for your body to absorb. This also means it mixes effortlessly into your morning coffee or post-workout shake.

Furthermore, we know that for many of our customers—from professional athletes to tactical professionals—purity is a matter of safety and career longevity. That is why we ensure our products are NSF for Sport certified. This third-party testing guarantees that what is on the label is in the bag and that there are no banned substances or harmful contaminants. When you choose BUBS, you are choosing a product that has been rigorously tested to support your wellness journey without the risks associated with lower-quality alternatives.

How to Integrate Creatine Into Your Wellness Routine

If you have decided that you want to reap the benefits of creatine for strength and recovery, the next step is doing it right. There are two common ways to start:

1. The Loading Phase: This involves taking about 20 grams of creatine a day (split into four doses) for 5 to 7 days. This quickly saturates your muscles. However, this is also the phase where people are most likely to experience minor side effects like bloating or stomach upset.
2. The Consistent Dose: You can simply take 3 to 5 grams of Creatine Monohydrate every single day. It will take a bit longer (about 3 to 4 weeks) to fully saturate your muscles, but it is much gentler on the digestive system and arguably more sustainable for a long-term wellness habit.

Research shows that over the long term, both methods are equally effective. At BUBS, we are fans of the daily habit. It is about consistency over intensity. Just one scoop a day can help you feel the difference in your training and recovery.

Synergy with Other Supplements

Wellness is about the whole picture, not just one ingredient. Many of our customers find that creatine works best when it is part of a broader, science-backed regimen.

For example, if you are looking to support your joints and connective tissues while building strength, our Collagen Peptides are a perfect partner. While creatine fuels the muscles, collagen provides the building blocks for the tendons and ligaments that support them. Together, they create a foundation for an injury-resistant, adventure-ready body.

If mental clarity and sustained energy are your goals, try adding a scoop of MCT Oil Creamer to your morning routine. The healthy fats from coconut oil provide a steady source of fuel for your brain, helping you stay sharp whether you are in the boardroom or on the side of a mountain.

And let's not forget the basics. A strong immune system and healthy digestion are the bedrocks of performance. Our Vitamin C and Apple Cider Vinegar Gummies are easy ways to ensure your body’s natural defenses and digestive functions are firing on all cylinders.

Who Should Avoid or Limit Creatine Use?

While creatine is safe for most people, we are all about transparency and safety. There are certain groups who should approach creatine with caution or avoid it altogether:

• People with Pre-existing Kidney Disease: As mentioned, the extra creatinine can put undue strain on kidneys that are already struggling.
• Individuals with Untreated Hypertension: If your blood pressure is currently high and not under control, it is best to avoid any supplement that could potentially influence vascular resistance until you have spoken with your doctor.
• Those with Bipolar Disorder: Some evidence suggests that because creatine affects brain energy, it might trigger manic episodes in individuals with bipolar disorder.
• Pregnant or Breastfeeding Women: There is a lack of long-term safety research in these specific populations, so it is generally recommended to wait.
• Children and Adolescents: While some young athletes use it, we recommend sticking to whole foods and proper training until the body is fully developed, unless otherwise directed by a physician.

For everyone else, Creatine Monohydrate remains one of the most effective tools in the wellness kit.

FAQ

Does creatine cause water retention that leads to high blood pressure? While creatine does cause water retention, it is primarily "intracellular," meaning the water is pulled inside the muscle cells rather than into the bloodstream. In healthy individuals, this shift in fluid does not typically lead to an increase in blood pressure. However, it is essential to stay hydrated by using products like Hydrate or Die to ensure your overall fluid balance remains stable.

Can I take creatine if I am already on blood pressure medication? If you have been diagnosed with hypertension and are taking medication, you must consult your physician before starting Creatine Monohydrate. Some studies suggest that high levels of creatine could potentially interfere with certain antihypertensive therapies or put extra strain on the kidneys, which are vital for blood pressure regulation.

Is it better to avoid the "loading phase" to prevent blood pressure spikes? For most people, the loading phase is safe, but it is the time when side effects are most likely to occur. If you are concerned about your blood pressure or have a sensitive stomach, skipping the 20-gram loading phase and starting with a steady 3 to 5 grams of Creatine Monohydrate daily is a great option. You will reach the same level of muscle saturation in a few weeks with much less stress on your system.

How does caffeine interact with creatine and blood pressure? Caffeine is a known stimulant that can temporarily raise blood pressure. Some older studies suggested that caffeine might counteract some of the performance benefits of creatine, though more recent research is mixed. If you are sensitive to stimulants or concerned about blood pressure, be mindful of your total caffeine intake when using Creatine Monohydrate, as the combination could potentially lead to a greater temporary increase in heart rate or blood pressure than either one alone.
