2:1 Drink

£19.99 £7.99

The 2:1 Drink is an isotonic sports beverage formulated for optimal absorption, supporting moderate to high energy demands while remaining light, refreshing, and not overly sweet.

Glucose and Fructose Formula

The formula combines glucose (as maltodextrin) and fructose, which are absorbed via different transporters in the gut. As each transporter has a limited capacity, relying on a single carbohydrate can slow absorption and increase the risk of gastrointestinal discomfort.

By combining these two carbohydrates in a 2:1 ratio, the 2:1 Drink allows you to absorb 60 grams (or more) of carbohydrates per hour without overloading your gut.

Flexible Dosage

Each serving provides 30 grams of carbohydrates, making it easy to scale your intake. Consume a single serving for moderate-intensity or shorter workouts. When energy needs are higher, drink multiple servings or stack with energy gels to reach 60 grams (or more) per hour. 

The 30-gram serving size also makes the 2:1 Drink ideal for gut training, helping you gradually adapt to higher carbohydrate intake so you can tolerate more on race day.

Baseline Hydration

Each serving contains 100 mg of sodium to help replace sweat losses and support fluid absorption. This moderate level makes it suitable for cooler conditions or athletes with lower sodium needs, or for those obtaining electrolytes from other sources.

Light Taste

Despite its ability to meet high-energy needs, the 2:1 Drink maintains a light, not overly sweet taste, making it easier to drink consistently and helping prevent flavour fatigue during long sessions.

The result is a flexible sports drink that helps you match energy intake to the demands of your day while supporting consistent absorption, gut comfort, and a long-term fueling strategy.

  • Preserves glycogen stores
  • 2:1 ratio supports high energy intake without digestive issues
  • Prevents muscle cramps
  • Contains 100 mg of sodium to support hydration
  • Vegan and free from artificial sweeteners

Mix one scoop (1 serving) with 250–500 ml of water, adjusting the volume to suit your hydration needs and preferred taste intensity.

Consume 1–3 servings per hour, depending on carbohydrate needs and personal tolerance. The 2:1 Drink can also be combined with energy gels or bars to achieve your hourly carbohydrate targets.

Each serving contains 100 mg of sodium. If sweating heavily, consider taking additional sodium alongside this drink.

Who should use the 2:1 Drink?
The 2:1 Drink is designed for endurance athletes, including cyclists, runners, triathletes, and long-distance competitors. It is particularly suitable for lengthy sessions at moderate to high intensity when your body needs energy that is rapidly absorbed. However, as it is not overly concentrated, it can also be used for lower-intensity exercise.

How many servings of 2:1 Drink should I take per hour?
The 2:1 Drink is designed for endurance athletes, including cyclists, runners, triathletes, and long-distance competitors. It is particularly suitable for lengthy sessions at moderate to high intensity when your body needs energy that is rapidly absorbed. However, as it is not overly concentrated, it can also be used for lower-intensity exercise.

What is the maximum number of servings I can take per hour?
Most athletes can comfortably absorb around 60 g of carbohydrates per hour (2 servings). Athletes accustomed to higher carbohydrate intake may tolerate up to 90 g per hour (3 servings). Everyone’s digestive system absorbs carbohydrates slightly differently, so it’s best to start with 1–2 servings per hour and gradually increase during training to discover what works best for you.

Can I use 2:1 Drink during races? 
Yes. The 2:1 glucose-to-fructose ratio supports greater carbohydrate absorption than single-carbohydrate drinks, making it suitable for long races with high energy demands. It also helps reduce the risk of gastrointestinal upset during high-intensity racing.

Why does the 2:1 ratio matter? 
The 2:1 glucose-to-fructose ratio is important because glucose and fructose are absorbed in the gut via different transporters. There is a limit to how much each transporter can process. On average, most people can absorb a maximum of 60 g of glucose and an additional 30 g of fructose per hour. By combining these carbohydrates in the right ratio, the 2:1 Drink allows you to absorb more total carbohydrates, helping provide steady energy and reducing the risk of stomach discomfort during long or intense sessions. However, these numbers aren’t fixed. Everyone’s digestive system absorbs carbohydrates a little differently, so individual tolerance may vary.

Which is better, a 2:1 or a 1:0.8 glucose-to-fructose ratio?
Both ratios are designed to take advantage of different gut transporters to increase carbohydrate absorption with less risk of digestive upset. However, digestive tolerance varies, so some athletes prefer 2:1, while others favour 1:0.8. The 2:1 ratio contains slightly less fructose, making it less sweet; the 1:0.8 ratio is a little sweeter. Ultimately, the best choice depends on your personal preference and what your body tolerates.

Can I use this drink for gut training?
Yes. Each serving provides 30 g of carbohydrates, which makes it easy to gradually increase intake over time, helping your digestive system adapt to higher carbohydrate loads for race day.

Why does this drink contain only 100 mg of sodium?
The 2:1 Drink is formulated as a flexible sports drink with moderate sodium levels. It performs well in cooler conditions, for athletes with lower sweat-sodium losses, or when additional electrolytes are obtained from other sources.

Should I add extra sodium when using this drink?
If you sweat heavily, train in hot conditions, or are prone to cramping, additional sodium may be beneficial. You can combine this drink with electrolyte or sodium products to meet your individual needs.

Can I combine 2:1 Drink with gels or bars?
Yes. Many athletes pair drinks with gels or bars to reach higher carbohydrate, sodium, and fluid targets per hour. For optimal digestive comfort and absorption, it’s recommended to pair with other products that have a 2:1 glucose-to-fructose ratio.

Is 2:1 Drink isotonic?
Yes. When mixed as directed, 2:1 Drink forms an isotonic solution that supports fluid absorption while delivering carbohydrates for energy.

Why does the nutrition label say that 2:1 Drink only contains 22 g of sugar?
Not all carbohydrates in 2:1 Drink come from sugars. A significant portion comes from maltodextrin, which isn’t counted as sugar on nutrition labels. Combined with fructose, the drink provides 30 g of carbohydrates per serving, even though the label indicates a lower sugar content.

How long is 2:1 Drink safe to drink after mixing with water?
If refrigerated, it is safe for up to three days. At room temperature — especially in hot weather — it is best consumed within one day.

Is 2:1 Drink gluten-free?
The drink itself contains no gluten. However, some flavours are produced on lines shared with oats, which may lead to cross-contamination with gluten-containing grains. Therefore, complete gluten-free assurance cannot be given. Please check the ingredients list on the product page for flavour-specific gluten information.

Great light taste

Great light taste. Not to sweat. Only downside is that i think er should be more sodium in it. Double it and it is perfect

Hi Jeroen, thanks for sharing your feedback! We’re glad you enjoy the light taste, and appreciate your suggestion about increasing the sodium. We’ll pass it along to our team. If you have any further questions or suggestions, feel free to reach out anytime. Best of luck with your next training sessions!

Quite simply the best refreshing siupplement

Quite simply the best refreshing supplement drink for endurance rides, I had my doubts but truly will never go without in my two bottles with either Lemon flavor or **** orange, amazing

Thanks, Darryl! Love hearing this, especially as you had your doubts at first. Great to know the 2:1 Drink has become a regular in both bottles on your endurance rides. Lemon and Orange are a pretty solid combination!

Prisvärd!

Väldigt bra smak trots 4 skopor i en flaska på 800ml. Körde 2 flaskor och hade fick inget magras.
Hjälpte mig igenom ett xc lopp på 4,5h på en Enduro mtb

Hej! Stort tack för din fina feedback! Underbart att höra att drycken gav dig bra energi utan magstrul under 4,5 tuffa timmar på cykeln. Kör hårt vidare och lycka till med träningen!

Sono molto sincero: rispetto ai prodotti che ho sempre preso al supermercato (di marche e qualità differenti ho sperimentato molto) qui la differenza si nota davvero. Prodotto ottimo: in piscina (nuoto ogni giorno) ne sento i benefici in termini di resistenza e a fine allenamento.

Ciao!
