Iso drink
Isodrink is an isotonic carbohydrate drink that provides fast and slow carbohydrates to give you sustained energy. The carbohydrates are in a maltodextrin-fructose ratio of 1:0.8.
The first isotonic drink on the market based on scientific evidence, with adjustable usage modes depending on the container used (250ml, 500ml, or 750ml). This makes it the most optimal isotonic drink on the market for hydration during training. Suitable for any type of sport: trail running, running, triathlon, cycling, and more.
This means we get a 6% carbohydrate concentration per water content in any of the containers used. Simply follow the recommended amounts in the Iso Drink usage table.
Iso Drink revolutionizes the isotonic drink market. It is a unique combination of maltodextrin and fructose (1:0.8 ratio) that allows glucose uptake in excess of 60 grams per hour, preventing saturation of the Slgt-1 and glut 5 transporters (glucose and fructose, respectively) and minimizing gastrointestinal discomfort. For more information: 1:0.8 ratio guide
Iso Drink has been specifically formulated to improve your performance during training and competitions. It helps you achieve the high energy intake required for intense endurance exercise.
This is the first carbohydrate energy drink that is made with freeze-dried fruit.
You can learn more about how to use our products with this guide: Usage Guide by Intensity and Duration.
HIGH ENERGY INTAKE
The ISO Drink range is designed to allow for high energy intakes. In fact, beginners will only need one dose of ISO Drink per hour to get all the energy they need. For those experienced in high carbohydrate intake per hour and who have specifically trained their digestive system by training the gut , they will be able to oxidize from 60 to >120 g carbohydrates/h in an activity of more than 90 minutes, which would be equivalent to taking the dose of ISO Drink plus one Lite 30 gel or one Lite 60 gel .

CARBOHYDRATE CONCENTRATION 6% ISO DRINK VERSUS 9% GLUT 5 DRINK
The ISO Drink range is designed with a 6% carbohydrate concentration in all its uses, from the 250ml, 500ml, or 750ml container. We adapt to any athlete.
The reason for formulating it at 6% is because the main objective of any isotonic drink is to rehydrate the athlete during physical exercise. Therefore, the goal of hydration is above providing energy, which is why we've included 6%, making the gastric emptying rate the fastest to date in FANTÉ, providing us with the most optimal and rapid rehydration available.
On the other hand, the carbohydrate drink GLUT 5 DRINK It is formulated to obtain the energy we need as quickly as possible and at the maximum concentration we can dilute in water. This concentration is 9%. This is the maximum concentration we can tolerate during training.
If you want to learn more about why 6% concentration is the fastest and 9% is the maximum concentration we tolerate, check out our guide .

IS IT BETTER TO SIP CARBOHYDRATE WATER MORE OFTEN BUT IN SMALLER AMOUNTS OR LESS OFTEN AND IN LARGER AMOUNTS?
Researchers at Loughborough University attempted to answer this question and found that less frequent sips and larger amounts produced better results . This is one of the reasons why, at Fanté, we have created a how-to guide that you can consult in this guide . Where we explain why it is better to take larger sips less often than smaller sips more often. We achieve this with our FANTÉ TEAM 750 bottle, ergogenically designed to provide large sips of water in a short period of time and created specifically for consuming the GLUT 5 DRINK single-dose . Since the amount of water used with our bottle, together with the total amount of carbohydrates per dose, is the correct concentration of 6%.
OPTIMAL CARBOHYDRATE RATIO 1:0.8
Science has proven that a combination of glucose (maltodextrin) and fructose in a 1:0.8 ratio is optimal for carbohydrate absorption during intense exercise. In our guide (Why Use 1:0.8 and Not Other Carbohydrate Ratios), we explain why science supports this ratio over other ratios currently on the market.
PALATABILITY
We avoid adding flavorings, colorings, sweeteners, and preservatives at all times, instead adding freeze-dried natural fruit. Tart apples of the highest quality, achieving an unparalleled flavor.
STAY HYDRATED
Replace only the electrolytes you need to maintain optimal hydration throughout exercise and allow your body to function as it should.
This hydration is achieved through our ISO GLUT 5. In our hydration guide, you can learn more about why we decided to include 300 mg of sodium per serving and be the first ISOTONIC to fully comply with the maximum tolerable concentration of carbohydrates/ml of water, based on current scientific evidence.
MIX AND MATCH
All our products are designed to work together. The ISO Drink range combines perfectly with the Gel 60 range, allowing us to achieve different hourly carbohydrate oxidation rates, adapting to any athlete, from beginners to professionals. The range is from 30 to over 120 grams/hour.
SIMPLY SCIENCE
