2:1 Jelly Bar+ (with caffeine)

£11.99 £8.99

2:1 Jelly Bar+ is an energy bar with caffeine, designed for optimal absorption. It helps you meet moderate to high energy demands while remaining easy to chew, not overly sweet, and convenient to carry.

Optimal Absorption

The bar contains glucose and fructose, two carbohydrates that are absorbed by different transporters in the gut. By combining these two carbohydrates in a 2:1 ratio, the 2:1 Jelly Bar+ allows you to absorb 60 grams (or more) of carbohydrates per hour without overloading the gut. 

It contains no fat, fibre, or protein, which can slow digestion and cause gut discomfort during intense exercise. This makes the 2:1 Jelly Bar+ ideal for long, intense exercise where you need fast energy to keep you going.

Caffeine Boost

In addition to carbohydrates, the 2:1 Jelly Bar+ contains 50 mg of caffeine. A well-established performance aid, caffeine helps improve focus, increase alertness, and reduce perceived exertion.

The dosage provides benefits without being excessive. For a larger boost or if you have a high tolerance, you can take multiple bars or combine with other caffeine products to reach your desired amount.

Flexible Dosage

Each bar provides 20 grams of carbohydrates, an amount that makes it easy to scale intake across different workouts.

Consume one bar per hour during lower-intensity or shorter workouts. When energy needs are higher, consume 2–3 bars per hour or combine with energy gels and sports drinks to reach your hourly energy targets.

Light Taste and Soft Texture

2:1 Jelly Bar+ contains 50% real fruit pulp, which gives it a naturally sweet taste. The soft texture makes it easy to chew and doesn’t leave a sticky residue on your teeth, making it enjoyable to eat even during hard efforts and supporting a consistent fuelling strategy.

  • Fast absorption
  • Preserves glycogen stores
  • Contains caffeine to increase alertness, focus, and time until exhaustion
  • Prevents muscle cramps
  • Soft texture for easy chewing
  • Does not melt or crumble

Consume 1–3 bars per hour during your workout, or combine with gels or drinks to meet your energy needs. You can also consume 1 bar before your workout. 

CautionThis product contains caffeine. Individual tolerance to caffeine varies. Monitor your total daily intake and avoid exceeding your personal tolerance. 

Note: 2:1 Jelly Bar+ only contains rapidly-digesting carbohydrates. Because it does not contain fat, fibre, or protein — which can slow digestion and cause gut discomfort during intense exercise — it is suitable for high-intensity workouts as well as low- and mid-intensity workouts.

ATTENTION! 

High dosage of caffeine: do not consume more than 4 Jelly Bar+ per day!

Who should use 2:1 Jelly Bar+?

2:1 Jelly Bar+ is designed for endurance athletes, including cyclists, runners, triathletes, and long-distance athletes. It is particularly suited for long workouts at low or moderate intensities when your body needs fast energy. However, because it’s not overly concentrated, it can also be used during lower-intensity workouts.

How many servings of 2:1 Jelly Bar+ can I take per hour?

Your carbohydrate intake should match the duration and intensity of your workout. For low- to moderate-intensity workouts lasting longer than 90 minutes, we recommend consuming up to 3 bars per hour (60 grams of carbohydrates). For higher carbohydrate needs, you can take up to 4 bars per hour (80 grams of carbohydrates).

However, everyone’s body absorbs carbohydrates a bit differently, and tolerance to caffeine varies, so it’s best to start with 1–2 bars per hour and gradually increase your intake during training to find what works best for you.

Can I use 2:1 Jelly Bar+ during races? 

Yes. The 2:1 glucose-to-fructose ratio supports higher carbohydrate absorption than single-carbohydrate bars, making it suitable for long races with high energy demands. The 2:1 ratio also helps reduce the risk of gastrointestinal discomfort when racing at high intensities.

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 absorb. 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, 2:1 Jelly Bar+ 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, the 2:1 or the 1:0.8 glucose-to-fructose ratio?

Both ratios are designed to take advantage of how the body absorbs glucose and fructose through different gut transporters, allowing you to take in more carbohydrates per hour with less risk of stomach discomfort. However, everyone’s digestive system digests carbohydrates slightly differently, so some athletes tolerate the 2:1 ratio better, while others prefer the 1:0.8 ratio. The 2:1 ratio contains slightly less fructose, making it less sweet, whereas the 1:0.8 ratio is a bit sweeter. Ultimately, the best choice comes down to your personal preference and what your body tolerates better.

Should I add extra sodium when using this bar?

If you sweat heavily, train in hot conditions, or are prone to cramping, additional sodium may be helpful. You can combine this bar with electrolyte or sodium products to meet your individual needs.

Can I combine 2:1 Jelly Bar+ with drinks or gels?

Yes. Many athletes combine bars with sports drinks or energy gels to reach higher hourly carbohydrate, sodium, and fluid targets. For optimal gut comfort and absorption, we recommend pairing it with other products that have a 2:1 glucose-to-fructose ratio.

Przyjemna konsystencja, galaretka jest miękka, łatwa do szybkiego zjedzenia. Smak jest OK, czuć też kofeine (charakterystyczna lekka gorycz). Stosowałem przed długimi wybieganiami i na pierwszą cześć biegu niosło jak trzeba, a biegłem rano bez posiłku.

Cieszę się, że produkt spełnił Twoje oczekiwania, Tomasz! Miło słyszeć, że pomaga podczas długich biegów. Dziękujemy za opinię!
