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.
