One 82-gram sachet to dissolve in 600 ml of water. SiS Beta Fuel 80 Strawberry and Lime provides 80 grams of carbohydrates per hour in an isotonic drink, based on maltodextrin and fructose in a 1:0.8 ratio. The flavor is a light strawberry and lime taste with a fresh and tangy note, pleasant to drink during longer sessions. 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 intestine quickly becomes saturated. A 1:0.8 ratio has been shown to increase carbohydrate oxidation efficiency from 62% to 74%, which means 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 contents before processing it. This is precisely what causes gastric problems with concentrated sports drinks. Beta Fuel 80 dissolves in 600 ml of water and then becomes isotonic, at the same concentration as blood and body fluids. The stomach processes it directly without extra fluid subtraction, reducing 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 longer than two hours. If you want to go higher in this range, combine the sachet with a Beta Fuel gel or chew bar. This way you can distribute the intake between drinking and eating and adapt it to what your stomach can handle 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, nut-free, suitable for vegans. Each production batch is controlled by Informed Sport according to the WADA prohibited substances list. The product does not contain sodium. For prolonged effort where you sweat a lot, add a HYDRO tablet or a HYDRO+ sachet to supplement sodium intake.
Beta Fuel 80 is a product for those who move for a long time at high intensity and take their carbohydrate intake seriously. For an effort of less than 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 82-gram sachet, in a 1:0.8 maltodextrin to fructose ratio. With the common 2:1 ratio, the SGLT1 transporter in the intestine quickly becomes saturated. The 1:0.8 ratio better distributes the load between the two transport pathways, allowing your intestine to 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 upset 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 reach the recommended 80-120 grams per hour for efforts lasting more than two hours. This allows you to split your intake between drinking and eating when your stomach can tolerate it.

For endurance athletes who perform efforts lasting 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 drinkable form that you can consume without gastric issues. It is not a daily supplement but a targeted energy source for prolonged effort.
Most dual-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 carbohydrates absorbable per hour and simultaneously increases the risk of feeling bloated. 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 more slowly than a clear liquid product. Add the powder gradually and shake several times. Once well 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 when you sweat a lot, this is a point to consider. SiS recommends adding a SiS HYDRO tablet or an HYDRO+ sachet to water, or drinking it separately alongside Beta Fuel. Sodium plays a role in fluid balance and fluid retention in the body.
GO Isotonic gels provide 22 grams of carbohydrates per 60 ml sachet and are already isotonic, ready to drink. Beta Fuel 80 provides 80 grams of carbohydrates per 82-gram sachet to be dissolved in 600 ml of water. For an hourly intake of 80 grams, you would therefore need 1 Beta Fuel sachet or almost 4 gels. Beta Fuel is more practical for those with a water bottle, while gels are more practical without one.
Orange, strawberry and lime, and red berry all have the same formula: maltodextrin (57%), fructose (42%), and flavor. Only the flavor differs. The flavors were intentionally kept mild so you can drink them for hours without flavor fatigue. Orange is the most neutral choice, red berry is light and fresh, and strawberry and lime has a slightly fresh and tangy note.
