The BETA Fuel range is proven to be scientifically superior, providing an optimised 1:0.8 ratio of maltodextrin to fructose, so athletes are able to achieve a 120g per hour carbohydrate intake during prolonged endurance exercise.Read more
[H2] BETA FAQs
[H5] What is BETA Fuel?
As an endurance athlete (your events typically last more than two hours), you need to take in between 80-120g of carbohydrate per hour.
The BETA range has been scientifically formulated to deliver maximal dual-source energy from Maltodextrin+Fructose, in a proven combined ratio of 1:0.8, so you can hit your target carbohydrate intake, enhance your power output, increase carbohydrate usage efficiency, and limit gastrointestinal discomfort.
[H5] What's the difference between BETA Fuel and GO Energy?
The BETA Fuel Energy Gel delivers 40g of carbohydrate in a single serving (compared to 22g from the GO Isotonic Energy Gel) to help you hit the recommended intake of 120g per hour during endurance exercise.
We have optimised this 40g of carbohydrates in our BETA Fuel Energy Gel with 1:0.8 ratio (maltodextrin to fructose) that increases your body’s carbohydrate usage efficiency, which in turn enhances your power output and limits gastrointestinal distress.
[H5] Should I use a BETA Fuel Gel, Drink or Chew?
The BETA Fuel range is designed to enable a mix and match approach to your endurance fuelling strategy, to provide a mix of products to enable you to hit your required carbohydate (~120g) intake per hour for activity lasting more than 2hrs.
BETA Fuel Gels deliver 40g of carbohydrate in an easy to consume format, whilst the BETA Fuel 80 delivers 80g carbohydrate in a single, convenient isotonic fuelling solution.
The BETA Fuel Energy Chew delivers 46g when consumed in one go, or can be broken into individual chews, with each chew containing approximately 7 grams of carbohydrate.
[H5] What's the difference between BETA Recovery and REGO Rapid Recovery?
BETA Recovery is an advanced carbohydrate & protein blend, scientifically formulated to support endurance athletes who require a complete recovery solution to ensure they are fully recovered before their next session.
After a hard session, your muscles and liver are likely depleted in glycogen. Fructose promotes recovery of liver glycogen stores, whereas maltodextrin can be directly taken up the muscle to replenish muscle glycogen stores. Just like the BETA Energy products, BETA Recovery includes dual source carbohydrates (maltodextrin + fructose in a 1:1 ratio) to rapidly replenish both liver and muscle glycogen stores.
BETA Recovery includes 30g of whey protein (vs 20g Soy protein in REGO Rapid) which provides the amino acids needed to promote muscle repair and maintenance post-exercise.
