Availability & prices


Our entire stock is online. That means that we have no products in a hidden corner. Every day we walk through the stock to keep this up-to-date and yet it can happen that we miss out. We will always contact us and offer an alternative (or possibly afterwards as soon as it is inside).

The stock is not huge and we do that consciously. How so? By having a smaller stock, we ensure that our stock is always equipped with the most recent and a long shelf life date. This way we ensure a rapid change of our products.

Are you planning to place a large order, such as for your entire team that goes on a training internship or participates in a nice multi -day tour such as Giro di Kika, the Pyrene Challenge or the Tour for Life? Let us know. We are happy to offer you a special deal.

By having our own stock, we can therefore quickly respond to your wishes. Ordered today (on working days) is often delivered the next day.

Did you know that you can also see the minimum expiration date of the products. Is there nothing to it? Then the product can be kept for at least 2 months. A THT date does not say much in sports nutrition, because the effect, taste and composition of the product only changes very slowly. Often you can use it for months (and sometimes years) after the indicated THT date.


Our prices are very competitive and often something cheaper than with the competitors. The basic price that we use is the Sales Advice Prize as advised by the supplier.

In addition to the already competitive prices, you can gain even more advantage by looking at our scale discounts or special packages. With this you often save between 3% and 5% on the product. The scale discounts can be found on the product page.


Science in Sport Beta Fuel has been developed to deliver the maximum amount of carbohydrates in a 2: 1 ratio of maltodextrin to fructose, while limiting gastrointestinal problems.

The product to concentration mixed is 80 grams of carbohydrate (2: 1 maltodextrin: fructose), 20 mmol / l sodium and 500 ml of liquid per portion.

Most important features:

  • • 2: 1 ratio Maltodextrin: Fructose
  • • 80 g total carbohydrate
  • • Isotonic
  • • PH-neutral
  • • Natural aromas and sweetener
  • • Added sodium, potassium, magnesium and calcium

Why is it called Beta Fuel? In development, a beta test is the second test phase in which a sample of the intended audience a product or service test. Beta Fuel has been tested in the elite since the summer of 2017 and we will continue to collect elite insight and complete the performance studies in 2018.

How does Beta Fuel work? A speed -limiting factor of exogenous carbohydrate use during exercise is the transport of the nutrients through the intestinal wall. As soon as the sodium -dependent transporter, used to transport maltodextrin, is saturated at 60 g per hour, extra carbohydrate in the form of fructose can be absorbed by another Transporter, GLUT5.

Refueling long endurance events (longer than 2.5 hours) requires 60-90 g of carbohydrates per hour. Beta Fuel has been developed to produce these high levels of carbohydrates with a minimum risk of GI problems. Why 2: 1 Now for Science in Sport? 2: 1 sports drinks are not new; However, historically they are supplied in Hypertone solutions, which means a high risk of stomach complaints and that is why we have avoided as a brand. Now, after a development cycle next to Team Sky, the Giro d'Italia winners of 2018, Beta Fuel is a groundbreaking technology that ensures the optimum dosage of carbohydrates while retaining an isotone solution.

What is the recommended use for Beta Fuel? Mix one portion of beta fuel with 500 ml of liquid and drink little and often during exercise to meet the requirements for refueling. No complicated instructions, our drink is not limited by the need to use a specific type of water such as other niche brands, just mix and go.
