The experts behind ESN

Nicolas Lother
Chief Product Officer
For us, quality isn’t a single step but the sum of everything – from the first idea to the finished product.
Stefan Schwarz
Vice President Quality
Others rely on spot checks – we don’t. Because mistakes happen at random, we consistently test every raw material and every batch in our in-house lab, without exception.
Dr. Mike O'Leary
Head of Product
A product can work as well as you like, but if the taste isn’t right, it doesn’t make it into our range. For me, effect and enjoyment always go hand in hand.
Daniel Margis
Research & Innovation Scientist
For me, every formula starts with one question: what does the latest research really say? Only then do we decide on ingredients and dosage.

Peak performance starts from within.

When you train hard, your body works even harder. Intense workouts, high-protein diets, and daily stress don’t just challenge your muscles—they put extra strain on your entire system, including vital organs like your kidneys. Over time, this can throw your body off balance, potentially affecting both your performance and overall well-being.

Your kidneys play a crucial role in filtering metabolic waste, maintaining fluid and electrolyte balance, and regulating pH levels. Heavy sweating, intense exercise, and oxidative stress can all increase the workload on these essential organs, making proper support more important than ever.

That’s where Kidney Support comes in. This advanced formula blends powerful plant extracts—like cordyceps, dandelion, and astragalus—with essential trace minerals including zinc, manganese, copper, and selenium. Together, they help support your body’s pH balance, protect against oxidative stress, and keep you performing at your best. Scientifically developed, optimally dosed, and built for athletes who never slow down.1,2
