OUR STORY

It all began with the vision of our founder, Klemen Kunej. At the end of his master’s studies in biochemistry, he began thinking about how to combine his deep passion for sport with his academic knowledge. As an avid enthusiast of performance-enhancing nutrition, he decided to take the entrepreneurial path and create his own brand. From the very beginning, he has emphasized the importance of developing sports nutrition products that are scientifically proven, safe, and effective in helping individuals achieve their goals.

 

“There’s a flood of sports supplements on the market today, making it difficult to know which ones you can truly trust. With our products, I want to bring transparency and confidence back to the field. Every product should be safe, thoroughly tested, and effective for its intended purpose.
- Klemen Kunej, Founder of Zenit Performance Nutrition

 

 

“I want Zenit to reflect the principles I strive to live by myself — whether that means putting in the necessary work and perseverance to build a company, complete my studies, or prepare for upcoming athletic challenges. Every day, I aim to make progress — in my career, in sport, and ultimately, in becoming a better human being.”
