Adaptogens are plants that thrive in extremely harsh conditions such as cold, wind, shade, and high-altitude mountains. These challenging environments, where nutrients are scarce, force them to endure constant stress and adapt to survive.

During prolonged exercise, it’s essential to maintain proper hydration and energy intake. The simplest way to achieve this is with a sports drink.

For optimal results, we recommend using Nrgy Unit Drink. It provides enough energy for an additional hour of exercise while replenishing the minerals lost through sweating, ensuring your hydration levels remain consistently high.

Energy gels and bars are excellent sources of energy that can be paired with an isotonic drink to enhance your workouts.

Energy gels are ideal for more intense sessions when you're out of breath and chewing an energy bar becomes difficult. Energy bars, on the other hand, are better suited for less intense workouts, where you can enjoy both the taste and the texture.

For most athletes, the best option is the 4Energy Gel, which provides a quick burst of energy without causing digestive issues. If you're engaging in high-intensity workouts that demand even more energy, the Nrgy Gel 45 is your ideal choice, as it contains twice the energy of a regular gel.

The most popular choice among energy bars is the 4Energy Bar, which is designed to be non-melting and non-crumbling. It delivers the same amount of energy as the 4Energy Gel and tastes incredibly good.

If you're looking to replenish electrolytes with an energy bar and prefer chocolate flavours, we recommend trying the Salty Bar.

After every workout, your energy stores are depleted, and your muscles experience strain. Therefore, it's essential to ensure proper recovery to prepare your body for future training sessions.

For recovery after the most intense workouts, we recommend the recovery drink Regen. It rapidly replenishes your energy stores with the optimal carbohydrate ratio, supports muscle repair with the purest protein source, and rehydrates you with added electrolytes.

If your workout is less intense, we suggest the Recovery Whey Formula. It will help restore your energy stores, repair damaged muscles, and rehydrate you after exercise.

If you are an active athlete with a (large) social media following, you can fill in the form. We'll get in touch with you as soon as possible.

Of course. If you and your club members are looking for a reliable nutrition partner, check out our Collaboration With Sports Clubs page.
