General

ESN Fundamental is a modern all-in-one supplement in powder form that has been specially developed for people who are physically active. The composition is tailored to the requirements of intensive training sessions and combines selected amino acids, creatine, beta-alanine and electrolytes – tailored to phases of increased physical exertion, whether in the gym, on the running track or in martial arts. The product is a signature product from MMA professional Christian Ecklerin.

The product is based on four functional active ingredient complexes: regeneration, performance, hydration and bioavailability. The combination of these areas forms a versatile basis for athletes who value efficiency, quality and a sensible nutrient supply – without any unnecessary additives.

Advantages and basic idea behind Fundamental

ESN Fundamental was developed to provide active people with comprehensive nutrition in four key areas: regeneration, performance, hydration and bioavailability.

The focus is primarily on regeneration and cell repair – a particularly important aspect for anyone who trains intensively on a regular basis. To this end, Fundamental contains specifically balanced amino acids such as L-glutamine, glycine, L-proline and L-carnitine, supplemented with vitamin C. While glycine and proline are important building blocks for the body's own collagen synthesis, vitamin C has been proven to support the normal function of bones, skin and cartilage. L-carnitine also plays a role in energy metabolism, which is particularly relevant in the recovery phase after exercise.

Another focus is on performance and exercise tolerance. With ingredients such as creatine, beta-alanine and citrulline malate, ESN Fundamental draws on established substances that have been used in the field of sports nutrition for years. Creatine has been proven to increase physical performance during short-term, intense exercise. Beta-alanine is often associated with increased buffer capacity in the muscles, while citrulline malate, as a precursor to nitric oxide, promotes blood flow and nutrient supply during training.

To ensure optimal nutrition even during long or particularly sweaty workouts, Fundamental supplements the formula with a targeted hydration and electrolyte complex. This contains minerals such as magnesium, potassium, calcium and sodium, supported by coconut water powder as a natural source of electrolytes. Magnesium and calcium contribute to normal muscle function, which is particularly important during intense exercise.

The product is rounded off with the addition of AstraGin®, an innovative plant extract which, according to the manufacturer, can improve the absorption of amino acids and micronutrients – a plus for anyone who wants to ensure that their nutrients are utilised as efficiently as possible.

Last but not least, the product also impresses in practical use: with a pleasantly refreshing cherry lemonade flavour, a vegan profile and a well-thought-out price-performance ratio (600 g tin, approx. 20 servings at £1.50 each), Fundamental is a functional addition to your everyday training routine.

Conclusion

ESN Fundamental is more than a classic pre-workout or recovery product – it is a well-designed all-in-one supplement for anyone who makes training an integral part of their daily routine. The combination of performance-enhancing ingredients such as creatine, beta-alanine and citrulline malate, supplemented by regeneration-supporting amino acids, electrolytes and functional micronutrients, makes Fundamental a versatile supplement for ambitious athletes.

Whether in the gym, on the mat, in the cage or on the running track, Fundamental provides the basis for more structure, clarity and effectiveness in your daily supplement routine. With a high-quality formula, sensible dosage and refreshing taste, it offers a modern solution for modern training requirements – functional, scientifically proven and formulated with practical application in mind.
