If it isn’t good enough for our brains and bodies, it isn’t good enough for yours. Transparency and ingredient quality are non-negotiable.
Meet Justin J. Polcari, founder & neuroscientist
The Story of GENN
As a grad student and athlete, I relied on caffeine and energy drinks but realized they weren’t sustainable. While in a PhD-track neuroscience program and conducting mindfulness meditation studies, I examined the science behind focus, energy, and cognitive performance. It became clear that energy, cognition, hydration, and overall wellness are deeply interconnected.
The energy drink crash isn’t a mystery. It’s predictable chemistry. Once I understood that, neuroscience and physiology led the way, not marketing.
I realized I didn’t need more energy. I needed energy that actually lasted. Your brain doesn’t run on caffeine. It runs on chemistry. Get the chemistry right and everything else follows.
Somewhere along the way we accepted that feeling wired and then wiped out was normal. It was never normal, just common.
I stopped asking, “How do I get more energy?” and started asking, “Why does my energy keep disappearing?” That question changed everything.
The goal was never just the drink. The goal was the 4pm version of yourself that still shows up like it’s 9am. Most energy drinks borrow from your future self, giving a spike now and a crash later. We took a different approach: extending duration, reducing excess, and pairing it with the hydration your brain actually needs to perform.
