Everything You Should Know Before Starting Creatine

As one of the most studied fitness supplements, creatine has a reputation for enhancing physical performance and helping athletes achieve their strength and endurance goals. But before jumping into the world of creatine supplementation, it’s essential to fully understand how creatine works, what benefits it provides, any potential drawbacks, and whether it’s a good fit for your goals. This guide will cover everything you should know before starting creatine.

1. What is Creatine?

Creatine is an organic compound found in foods like meat and fish. Contrary to some misconceptions, creatine is not a steroid; it’s a naturally occurring substance in our bodies, synthesized from amino acids like glycine and arginine. While our bodies can produce creatine on their own, this amount typically isn’t enough to maximize high-intensity athletic performance. Therefore, supplementation can help fill the gap, supporting energy production during intense physical activities.

Most creatine supplements come in the form of creatine monohydrate, which is the most studied and effective version. Other types, such as creatine ethyl ester or buffered creatine, claim to be more efficient, but research has yet to show significant differences in effectiveness compared to monohydrate. So, if you’re considering creatine, monohydrate is the recommended and most cost-effective form.

2. How Does Creatine Work in the Body?

Creatine supports the body’s energy system, specifically in the phosphocreatine (PCr) energy pathway. When you exercise, especially at high intensity, your muscles rely on adenosine triphosphate (ATP) for energy. ATP quickly depletes during intense activities, leaving behind adenosine diphosphate (ADP), which is essentially ATP’s “used up” form. Here’s where creatine shines — it helps convert ADP back into ATP, enabling your muscles to continue performing at a high level.

Since the phosphocreatine system is primarily used during the first few seconds of high-intensity activities, creatine’s effects are particularly noticeable in short bursts of activity, such as weight lifting, sprinting, or explosive sports like football or basketball. With increased energy stores, creatine can help athletes achieve more intense, prolonged, and efficient workouts.

3. The Proven Benefits of Creatine

Creatine’s popularity isn’t just a fad; numerous studies have shown that it offers a range of benefits, from athletic performance to cognitive health.

a. Enhanced Athletic Performance

  • Strength Gains: Creatine is a go-to supplement for strength athletes, as it allows for longer, more intense workouts. Studies show that supplementing with creatine can lead to improved strength, enabling individuals to lift heavier weights and perform more repetitions.
  • Speed and Power: Athletes focused on sports requiring speed, agility, and explosive movements often benefit from creatine’s support in the phosphocreatine energy system, which is essential for short bursts of power.

b. Muscle Growth

  • Hypertrophy (Muscle Growth): Creatine can indirectly promote muscle growth by allowing athletes to train harder, leading to better gains over time. While the effect on hypertrophy is not massive, studies suggest that even a small benefit can be meaningful in the long run, especially when combined with regular, progressive training.

c. Fat Loss

  • Although not as extensively studied as creatine’s effect on strength, some recent research suggests that creatine could have fat-burning properties. This benefit is likely due to increased energy expenditure and improved workout performance.

d. Cognitive Benefits

  • Enhanced Brain Function: Beyond physical benefits, creatine has shown promise in cognitive health, particularly with regard to memory, focus, and cognitive resilience. Since creatine also fuels the brain’s ATP needs, it may have positive effects on cognition, especially during mentally demanding tasks.

4. Potential Drawbacks of Creatine

While creatine has a strong safety profile, a few considerations may make some people pause before adding it to their routine.

a. Water Retention and Bloating

  • Bloating Effect: One of the most common side effects of creatine supplementation is water retention within the muscles. This effect is usually temporary and happens because creatine pulls water into the muscle cells, making them appear fuller. Some athletes appreciate this “pump” effect, while others might find it off-putting, particularly if they’re looking to achieve a lean appearance.
  • Slight Weight Gain: This water retention can also lead to a minor increase in body weight, which could be a drawback for people aiming to reduce their weight. For those who don’t mind a bit of added bulk, this may not be a concern.

b. Hair Loss Concerns

  • The notion that creatine causes hair loss stems from a single study, which found that creatine supplementation slightly increased levels of dihydrotestosterone (DHT), a hormone associated with male-pattern baldness. However, this study did not directly show that creatine causes hair loss; rather, it suggested that people who are already genetically predisposed to hair loss might see an accelerated effect due to the rise in DHT.
  • Anecdotal Reports: Despite the lack of concrete evidence, anecdotal reports of hair loss have led some users to discontinue creatine. While not definitive, if you’re concerned about hair loss, you might consider monitoring any changes if you decide to try creatine.

c. Kidney Health Concerns

  • Creatine has faced scrutiny regarding potential kidney damage, though the overwhelming consensus in the scientific community is that creatine does not harm the kidneys in healthy individuals. However, people with pre-existing kidney issues should be cautious and consult a healthcare provider before starting creatine. Animal studies have shown that extremely high doses of creatine could be damaging, but these doses far exceed what humans typically consume.
  • In standard doses, creatine is well-tolerated and not associated with kidney damage, so it is generally considered safe when taken responsibly.

5. Non-Responders: Why Creatine Doesn’t Work for Everyone

Approximately 30% of individuals may experience little to no benefit from creatine supplementation. These individuals are known as “non-responders,” meaning that their bodies don’t respond to creatine in the same way as others. Researchers believe that non-responders might naturally produce sufficient creatine or consume enough through their diet, thus making supplementation unnecessary.

Identifying whether you’re a non-responder can only be done by trial and observation. If you take creatine and don’t notice any improvement in strength or endurance over time, you might fall into this category. Keep in mind, however, that not seeing immediate results doesn’t automatically mean you’re a non-responder; other factors, like diet and training intensity, also play a role.

6. How to Take Creatine: Dosage and Timing

The most recommended type of creatine is creatine monohydrate, and here’s a standard approach for effective supplementation:

  • Loading Phase (Optional): To saturate muscle creatine stores quickly, some people begin with a “loading phase,” taking 20 grams daily (divided into 4 servings of 5 grams each) for the first 5–7 days.
  • Maintenance Phase: After the loading phase, take 3–5 grams per day for maintenance. If you choose not to load, simply begin with 3–5 grams daily. It may take a bit longer to see results, but the benefits will still accumulate over time.
  • Timing: While creatine can be taken at any time, some people prefer to take it post-workout for convenience. What’s most important is consistency, so taking it at a time that fits your routine is ideal.

7. Safety and Final Thoughts

Creatine remains one of the most researched and widely recommended supplements for its benefits in strength, endurance, muscle growth, and cognitive health. With minimal risks and a strong safety profile, creatine is safe for most people when taken in proper dosages.

While creatine is not a miracle supplement, its benefits are tangible, and its consistency in scientific studies makes it a popular choice among athletes and fitness enthusiasts alike. If you’re concerned about potential side effects like water retention, weight gain, or anecdotal hair loss, monitor your response carefully. For those who experience minimal changes or unwanted effects, skipping creatine or limiting its use may be the best option.

If you’ve reached this point and feel ready to give creatine a try, remember to stick with creatine monohydrate, which is effective, cost-efficient, and backed by science.
