Product Description

Designed specifically for endurance athletes engaged in events lasting over two hours, the Science in Sport Beta Fuel Dual Source Energy Drink provides an optimized 80g of carbohydrate in a single, convenient isotonic solution. By delivering a precisely calculated amount of carbohydrates, this fuel allows you to maintain peak performance while minimizing the risk of gastrointestinal issues.

The Science in Sport Beta Fuel range is the result of an extensive collaboration between elite athletes and our dedicated Performance Solutions team. Recognizing the importance of athlete feedback and real-world testing, we worked closely with professionals who demanded the highest standards in their fueling products. This partnership allowed us to gather valuable insights and optimize the Beta Fuel formula to deliver a scientifically superior energy drink.

Through rigorous research and testing, we have developed a fuel that surpasses previous offerings in terms of performance benefits. Our innovations have resulted in a product line available in various formats, catering to the unique preferences and needs of athletes. Whether you prefer ready-to-drink bottles, powder mixes, or other convenient options, Beta Fuel ensures you have the flexibility to integrate it seamlessly into your training regimen.

The most significant breakthrough of Beta Fuel lies in its 1:0.8 ratio of carbohydrates, which sets it apart from the traditional 2:1 ratio found in other energy drinks. This optimized ratio has been scientifically proven to unlock a range of advantages. Firstly, it assists with exogenous carbohydrate oxidation by an impressive 17%, meaning your body can utilize the fuel more efficiently during exercise (O'Brien et al). This results in improved energy output and endurance, allowing you to push harder and maintain peak performance for longer durations.

In addition to increased energy utilization, Beta Fuel's 1:0.8 ratio also boosts mean power output during maximal sprint efforts. Athletes using Beta Fuel experience a 3% improvement in power output compared to those using the 2:1 ratio (O'Brien et al). This advantage can make a significant difference in high-intensity activities and crucial moments of competition, enabling you to gain that extra edge over your opponents.

Moreover, the new ratio significantly assists with the efficiency of carbohydrate oxidation. When consuming Beta Fuel in the 1:0.8 ratio, 74% of ingested carbohydrates are efficiently utilized by the body, compared to only 62% with the 2:1 ratio (O'Brien et al). This improved efficiency ensures that you extract the maximum energy from the fuel you consume, assisting with your endurance and overall performance.

Athletes who have switched to Beta Fuel in the 1:0.8 ratio have reported fewer symptoms of stomach fullness and nausea compared to those using the 2:1 ratio (O'Brien et al). This means that not only does Beta Fuel optimize your fuel intake and energy utilization, but it also minimizes the risk of gastrointestinal discomfort that can hamper performance and enjoyment.

By choosing Science in Sport Beta Fuel, athletes gain access to a meticulously developed energy drink that maximizes carbohydrate intake by 17% compared to previous offerings. Its scientifically superior 1:0.8 ratio of carbohydrates assists with energy utilization, power output, and efficiency while minimizing gastrointestinal issues. Trust in Beta Fuel to provide you with the fueling advantage you need to excel in your endurance pursuits.

  • Scientifically superior fuel optimized for endurance athletes
  • Contains an ideal 1:0.8 ratio of 80g carbohydrate
  • Increases power output during intense efforts
  • Improves the efficiency of carbohydrate utilization
  • Reduces symptoms of stomach fullness and nausea
  • Minimizes the risk of gastrointestinal discomfort

How does it work?

The Science in Sport Beta Fuel Energy Drink works by providing endurance athletes with a scientifically optimized fuel source to assist with their performance. The 1:0.8 ratio of 80g carbohydrate in each serving is carefully formulated to meet the specific needs of athletes engaged in prolonged activities lasting more than two hours.

During endurance exercise, the body's demand for carbohydrates increases significantly. Beta Fuel addresses this need by delivering an ideal amount of carbohydrates that can be efficiently utilized by the body. The 1:0.8 ratio has been shown to assist with exogenous carbohydrate oxidation by 17%, allowing athletes to derive more energy from the fuel they consume (O'Brien et al).

Furthermore, the Beta Fuel Energy Drink improves mean power output during maximal sprint efforts by 3% compared to the traditional 2:1 ratio, enabling athletes to generate more force and maintain a competitive edge (O'Brien et al). It also assists with the efficiency of carbohydrate utilization, with 74% of ingested carbohydrates being oxidized, compared to 62% with the 2:1 ratio (O'Brien et al).

One significant advantage of Beta Fuel is its ability to minimize gastrointestinal discomfort. Athletes who consume the 1:0.8 ratio experience reduced symptoms of stomach fullness and nausea compared to those using the 2:1 ratio (O'Brien et al). This ensures that athletes can fuel their bodies without compromising their performance or experiencing discomfort during intense activities.
