All our products are made with 100% certified organic ingredients and are therefore GMO-free. They do not contain high fructose corn syrup or other refined sugars. They are also free from artificial flavors, colors, binders and preservatives. No synthetic junk, just 100% natural.

Our goal is to remove packaging from all our products that you use on the road. And replacing these with reusable packaging methods. Our first solution for this is the Energy Flask . In addition, we use climate-neutral packaging and all ingredients are made in an ecologically responsible way.

All our products have a unique taste and are very easy to eat before, during and after exercise. This is because our products are handmade, from real food such as dried fruit, fruit syrups and nuts. This ensures that they have a unique and delicious taste. Mother Nature takes care of this, not a laboratory. We don't add fillers, seasonings, sugars, maltodextrin or other junk.

The Energy Bite is a tasty energy bar made with a nutritious mix of natural ingredients. In bite-sized portions for convenience and to prevent waste.

Energy Bites provide energy from multiple natural carbohydrate sources in small portions that slow digestion to provide needed energy.

Eating Energy Bites two to three hours before activity helps store energy in the muscles for use during your activity. Eating Energy Bites during a sporting activity will keep you going by slowing down the consumption of glycogen (the energy stored in your muscles and liver). This allows your engine to run longer, at higher rpm. After your activity, eating Energy Bites can help replenish these energy stores so that you recover faster.

The Energy Bites are different from other energy bars because they are made from 100% natural and nutritious ingredients such as dates, raisins and apricots. And then nuts, spices, lemon and, for example, salt for delicious flavors and necessary nutrients.

Experiments have shown that consuming 10 grams to 15 grams of carbohydrates in one go reduces the risk of blood sugar levels rising too high. You can solve the problem of eating too much or too little by eating small amounts more regularly. That is why we make our Energy Bites in bite-sized portions of 20 grams. This also prevents waste, because you don't always need a 60g bar.

Dried fruit has natural nutrients such as potassium, magnesium and calcium, which you miss in a maltodextrin product. The glycemic index (the rate at which blood sugar levels rise after eating a food) of dried fruit is about half that of maltodextrin or refined sugar commonly used in traditional energy bars. Our products therefore have a lower glycemic index, which ensures more stable blood glucose levels during exercise instead of a roller coaster of high and low blood glucose levels. Dried fruit also naturally contains a mix of fructose and glucose, making it easy to digest.

An Energy Shot is a delicious alternative to energy gels, made with a nutritious blend of 100% natural ingredients to provide cyclists and other athletes with a healthy energy source. They can easily be taken along during a ride. Typically as quick energy towards the last part of your training or tour.

Kalkman Energy Shots provide energy from multiple natural carbohydrate sources in bite-sized portions that are easy for the digestive system to tolerate. Because they are made from natural ingredients, your body can recognize them more easily and this reduces the risk of stomach complaints.

Eating Kalkman Energy Shots during a sporting activity will keep you going by slowing down the consumption of glycogen (the energy stored in your muscles and liver). This allows your engine to run longer at higher speeds, so to speak.

The Energy Shots are different from other energy gels because they are made from 100% natural and nutritious ingredients such as maple, apple and date syrup. We add a touch of lemon and salt for further taste and nutrients.

Maple syrup is produced by boiling sap from maple trees to remove water. The natural sugar content then reaches 66%. This simple processing gives maple syrup nutritional benefits such as a high mineral and polyphenol content, a low glycemic index and a blend of carbohydrates. A natural energy source.

Maple syrup is rich in nutrients such as potassium, magnesium and calcium, which you miss in a maltodextrin product. The glycemic index (the rate at which blood sugar levels rise after eating a food) of maple syrup is half that of maltodextrins – the most common base ingredient for traditional gels. Our products therefore have a lower glycemic index, which ensures more stable blood glucose levels during exercise, instead of a roller coaster of high and low blood glucose levels. Maple syrup also naturally contains a mix of fructose and glucose, making it easy to digest.

Hydro Drink is a hypotonic sports drink. This means that the concentration of electrolytes and carbohydrates in the sports drink is lower than the level in your body. This is important because it gives it optimal hydration properties. A hypotonic sports drink replenishes your body fluids more effectively than higher concentrated sports drinks such as isotonic and hypertonic. Hypotonic = moisture level returns to normal faster.

Hydro Drink is made to maintain your body fluids during exercise as effectively as possible. It is not an energy drink with carbohydrates. A sports drink with more carbohydrates will be absorbed less quickly by your body.

Kalkman products are made in such a way that drinking and eating are simple and effective. By putting fewer carbohydrates in Hydro Drink, you are able to get the necessary energy from the Energy Bites and Shots. Depending on intensity, duration and your condition.

Hydro Drink is based on concentrated grape juice. In addition to the neutral taste, grape juice has the right amount of carbohydrates and minerals. By using a liquid juice, it has undergone much less processing, which retains the natural flavors and nutrients. In addition, liquid is easier to mix in your water bottle. No powder dust cloud and less bulky packaging.

This is a convenient and sustainable way to use Energy Shots. See everything about the Energy Flask here.
