GU Energy Labs

We believe eating is training. Which is why, for over 25 years, we've been driven to answer three simple questions: What to eat? When to eat? How much to eat? We ask these questions over and over again... during training, on the trail, in the lab, at the end of a marathon, before a triathlon, in the feed zone, during halftime, at the summit, in the gym... and what have we learned? A lot.

Our innovative spirit has continued to drive us toward new recipes and tweaks informed by the latest scientific research. It’s driven us to expand with products that solve our body’s need for optimum hydration and effective recovery. But through it all, we haven’t stopped asking those three simple questions… what to eat, when to eat, and how much to eat.

Amongst all this innovation, the two letters G, U, bring us back to our roots. They remind us to keep it simple… give our bodies only what it needs, when it needs it, as quickly and easily as possible.

Founder Story
GU President Magda Boulet got her first job with GU in 1999. At that time, she was seeking advice for fueling her post-college (UC Berkeley) running nutrition goals. She began in the company's research department, eventually working her way up to lead research assistant, collaborating with GU co-founder Dr. Bill Vaughan.

In 2007, Magda left GU to pursue a professional running career, which included earning a spot on the 2008 U.S. Olympic Marathon Team and multiple World Cross Country Championship team medals. In 2013, she returned to GU as Vice President, leading several departments including Research & Development and Innovation.

Magda was named GU President in 2021 and now collaborates with Dr. Bill Vaughan's son, Brian Vaughan. In Boulet’s new role, she sees expanding inclusivity as one of her main goals. In addition to serving as GU's President, Magda is a dedicated mother, wife, and professional runner.
