Legal Supplements to Boost Cycling Performance in 2025
TL;DR
Beta-alanine, caffeine, and sodium bicarbonate are key legal supplements proven to enhance performance in endurance cycling.
What Are the Key Supplements for Endurance Cycling?
Legal supplements for endurance cycling include beta-alanine, caffeine, and sodium bicarbonate.
For endurance cyclists aiming to boost performance, beta-alanine, caffeine, and sodium bicarbonate are key supplements backed by research. These substances are not only legal for use in professional sports, as per the World Anti-Doping Agency's Prohibited List, but they have also been shown to significantly enhance endurance cycling performance. Here's a closer look at how each plays a role.
Beta-Alanine is a non-essential amino acid that's critical for increasing muscle carnosine levels. Why does this matter? Carnosine acts as a buffer against acid in muscles, delaying the onset of fatigue. A meta-analysis of 15 studies involving over 360 participants revealed that beta-alanine supplementation can improve time to exhaustion by an average of 16.9%, a significant boost for long-distance cyclists.
Caffeine is perhaps the most widely used performance enhancer in the world, and for good reason. It's known to increase alertness and reduce perceived effort, which can be a game-changer during long rides. Specifically, caffeine has been shown to improve endurance exercise performance by up to 3.2%, according to a review of over 40 studies. This is achieved by blocking adenosine receptors in the brain, which in turn reduces the sensation of effort during exercise.
Sodium Bicarbonate, on the other hand, works by buffering lactic acid build-up in the muscles. This can delay fatigue and improve sprint performance at the end of a long ride. Research shows that taking sodium bicarbonate can boost performance by up to 2.2% in activities lasting from 1 to 7 minutes, which is particularly relevant for cyclists looking to finish strong.
It's important, though, to consider individual tolerance and potential side effects when supplementing with these substances. For example, sodium bicarbonate can cause gastrointestinal issues in some people, while caffeine's effects can vary widely from person to person. Therefore, it's essential to start with lower doses to assess tolerance.
Unlike some supplements that offer marginal benefits at best, beta-alanine, caffeine, and sodium bicarbonate have solid evidence backing their efficacy for endurance cyclists. Whether you're training for a race or looking to improve your long-ride performance, incorporating these supplements, when used correctly, can provide a significant edge. And when it comes to ensuring you're choosing high-quality supplements, the ProveIt app can help you compare brands and check for third-party testing verification, ensuring what's on the label is what's in the bottle.
How Do These Supplements Improve Performance?
These supplements improve performance by enhancing endurance, reducing fatigue, and optimizing recovery.
Supplements like beta-alanine, caffeine, and sodium bicarbonate have been shown to significantly boost performance in endurance sports such as cycling. They achieve this by enhancing endurance, reducing fatigue, and speeding up recovery. Let's dive into how each of these supplements works and why they're particularly useful for endurance athletes.
Beta-alanine stands out for its ability to increase muscle carnosine concentrations, which play a crucial role in buffering hydrogen ions during high-intensity activity. This buffering capability can delay the onset of muscle fatigue and improve exercise performance. Research underscores its effectiveness, with studies showing that beta-alanine can enhance performance by 2.85% when athletes participate in exercises lasting one to four minutes. This is particularly meaningful in cycling, where even small improvements can be the difference between winning and losing.
Caffeine is another powerhouse for endurance athletes, widely used by up to 70% of them. Its mechanisms are multifaceted, including the ability to increase the availability of free fatty acids for energy, thereby conserving muscle glycogen stores. This shift in fuel utilization can significantly extend the duration of exercise before exhaustion sets in. Moreover, caffeine also has a well-documented effect on reducing the perception of effort, which means athletes can push harder for longer. The significance of caffeine's impact on performance cannot be overstated, with evidence suggesting improvements in endurance capacity of up to 3.2%.
Sodium bicarbonate, although perhaps less known than caffeine and beta-alanine, offers its own unique benefits. By counteracting the drop in pH levels associated with high-intensity exercise, sodium bicarbonate can delay acidosis and, consequently, fatigue. This results in improved performance in high-intensity activities, with studies indicating that it can lead to a 1.7% improvement in times for short-duration cycling time trials.
However, it's important to note that these supplements don't work in isolation. Their effectiveness can be influenced by factors such as dosage, timing, and individual physiological responses. For example, the benefits of caffeine can vary widely depending on an individual's tolerance and the specific amount consumed. It's also critical for athletes, especially those competing at high levels, to ensure their supplements are legal and safe. The World Anti-Doping Agency's Prohibited List is an essential resource for this, helping athletes avoid substances that could lead to disqualification.
Incorporating these supplements into an athlete's nutritional strategy can significantly impact their training and competition outcomes. By understanding the how and why behind each supplement's effectiveness, endurance athletes can make informed decisions that align with their performance goals and health considerations. And for those looking to ensure they're choosing high-quality supplements, platforms like the ProveIt app can be invaluable in comparing brands and verifying third-party testing.

What Are the 2025 Regulations on Supplements?
WADA's Prohibited List and UCI regulations determine the legality of supplements in professional cycling.
For professional cyclists, staying on the right side of the 2025 World Anti-Doping Agency's (WADA) Prohibited List and adhering to Union Cycliste Internationale (UCI) regulations is essential for both fair play and optimal health. These guidelines are designed to maintain a level playing field and ensure athletes' well-being by outlining which supplements and substances are off-limits.
What we know from research is that legal supplements like beta-alanine, caffeine, and sodium bicarbonate can significantly enhance endurance cycling performance. For instance, caffeine, a widely studied ergogenic aid, has been shown to improve endurance performance by up to 3-4% when consumed in doses of 3-6 mg per kilogram of body weight about an hour before exercise. Likewise, beta-alanine supplementation has been associated with improved performance in high-intensity activities lasting one to four minutes by increasing muscle carnosine levels. This is important because it delays muscle fatigue and enhances overall performance, a critical advantage in competitive cycling.
Sodium bicarbonate, another legal supplement, works by buffering lactic acid build-up in muscles, thereby delaying the onset of fatigue during intense efforts. Studies have demonstrated that taking 300 mg per kilogram of body weight about one to two hours before competition can provide a noticeable performance boost. This mechanism is crucial for cyclists, particularly in events that demand short, intense bursts of effort or in the final sprint of a race.
However, the effectiveness of these supplements can vary based on individual factors like diet, the type of activity, and tolerance levels. For example, caffeine’s ergogenic effects might be less pronounced in individuals with a high daily caffeine intake compared to those who consume it sparingly. This nuance underscores the importance of personalized nutritional strategies in optimizing performance.
The significance of adhering to WADA and UCI guidelines can't be overstated. They ensure athletes compete fairly and safely, while also leveraging legal supplements to achieve their performance and recovery goals. For those in professional cycling, it’s crucial to stay informed about which substances are prohibited and which are permitted to not only avoid potential sanctions but also to harness the benefits of legal supplements effectively.
