An 82-gram sachet to dissolve in 600 ml of water. SiS Beta Fuel 80 Red Berry provides 80 grams of carbohydrates per hour in an isotonic drink form, based on maltodextrin and fructose in a 1:0.8 ratio. The flavor is a light red berry taste without artificial sweetness, pleasant to drink during intense effort. Gluten-free, suitable for vegans, Informed Sport certified.
Traditional dual-source sports drinks use a 2:1 maltodextrin to fructose ratio. With the common 2:1 ratio, the SGLT1 transporter in the gut quickly saturates. A 1:0.8 ratio has been shown to increase carbohydrate oxidation efficiency from 62% to 74%, representing 17% more carbohydrates used per hour for the same intake. At the same time, participants reported fewer symptoms of bloating and nausea. Based on this research, SiS has reconfigured the entire Beta Fuel range to the 1:0.8 ratio.
A sports drink with 80 grams of carbohydrates in 500 ml of water would be hypertonic, meaning the stomach draws fluid to dilute the content before processing it. This is precisely what causes gastric upset with concentrated sports drinks. Beta Fuel 80 dissolves in 600 ml of water and then becomes isotonic, at the same concentration as blood and bodily fluids. The stomach processes it directly without additional fluid subtraction, which reduces the risk of bloating or nausea.
One sachet per hour provides 80 grams of carbohydrates, at the lower end of the recommended range of 80 to 120 grams per hour for endurance efforts lasting more than two hours. If you want to increase this intake, combine the sachet with a Beta Fuel gel or chew bar. This allows you to spread the intake between drinking and eating and adapt it to what your stomach can tolerate at that moment. Drink small sips regularly and don't put the bottle aside before emptying it.
The ingredient list is short: maltodextrin (57%), fructose (42%), and flavor. No preservatives, no colorings, no sweeteners. Gluten-free, lactose-free, wheat-free, and nut-free, suitable for vegans. Each production batch is tested by Informed Sport against the WADA prohibited substance list. The product contains no sodium. During prolonged effort where you sweat a lot, add a HYDRO tablet or HYDRO+ sachet to supplement sodium intake.
Beta Fuel 80 is a product for those who exercise for a long time at high intensity and take their carbohydrate intake seriously. For efforts under two hours, the dosage of 80 grams per hour is too high for most athletes. The product is then not the most logical choice compared to one or two separate GO gels per hour.
Beta Fuel 80 provides 80g of carbohydrates per 82g sachet, in a 1:0.8 maltodextrin to fructose ratio. With the common 2:1 ratio, the SGLT1 transporter in the gut quickly becomes saturated. The 1:0.8 ratio better distributes the load between the two transport pathways, so your gut can process more carbohydrates per hour.
With a high concentration of carbohydrates in a sports drink, gastric emptying is a risk. Beta Fuel 80 is an isotonic solution in 600 ml of water, which means the concentration is equal to that of blood and body fluids. The stomach therefore does not need to draw in additional fluid to process the contents. Less bloating, faster absorption. The 1:0.8 ratio also reduces self-reported gastric distress compared to 2:1 mixtures.
The ingredient list is short: maltodextrin (57%), fructose (42%) and flavor. No artificial colors, no preservatives, no sweeteners. Gluten-free, lactose-free, wheat-free, and nut-free. Suitable for vegans. Informed Sport certified by production batch.
One sachet per hour provides 80 grams of carbohydrates. By combining it with one or two Beta Fuel gels, you'll reach the recommended 80-120 grams per hour for efforts lasting over two hours. This allows you to divide your intake between drinking and eating when your stomach can handle it.

For endurance athletes who exert themselves for more than two hours, such as cyclists, triathletes, marathon runners, and ultra-runners. At this intensity and duration, glycogen stores are depleted if not replenished. Beta Fuel 80 provides 80 grams of carbohydrates per hour in a drink form that you can take without gastric issues. It's not a daily supplement but a targeted energy source for prolonged exertion.
Most two-source carbohydrate sports drinks use a 2:1 maltodextrin to fructose ratio. At this ratio, the SGLT1 transporter in the gut quickly becomes saturated, which caps the amount of absorbable carbohydrates per hour and simultaneously increases the risk of bloating. The 1:0.8 ratio better distributes the load between the two transport pathways in the gut. Fewer bottlenecks, more carbohydrates processed per hour, and less risk of gastrointestinal issues during exercise.
Add the entire 82-gram sachet to 600 ml of water in a bottle and shake well. The powder dissolves a little slower than a clear liquid product. Add the powder gradually and shake several times. Once completely dissolved, it's ready. Drink small sips regularly throughout the effort, not all at once.
No, the powder does not contain sodium. During prolonged exertion where you sweat a lot, this is a point to consider. SiS recommends adding an SiS HYDRO tablet or an HYDRO+ sachet to water, or drinking it separately alongside the Beta Fuel. Sodium plays a role in fluid balance and fluid retention in the body.
GO Isotonic gels provide 22 grams of carbohydrates per 60ml sachet and are already isotonic in themselves, ready to drink. Beta Fuel 80 provides 80 grams of carbohydrates per 82-gram sachet, to be dissolved in 600ml of water. So, for an hourly dosage of 80 grams, you would need 1 Beta Fuel sachet or almost 4 gels. Beta Fuel is more convenient for those with a bottle, while gels are more convenient without a bottle.
Orange, strawberry and lime, and red berry all share the same formula: maltodextrin (57%), fructose (42%), and flavoring. Only the flavoring differs. The flavors were intentionally kept mild in intensity, so you can drink them hour after hour without flavor fatigue. Orange is the most neutral choice, red berry is light and fresh, and strawberry and lime has a slight fresh and tangy note.
