GU Energy Labs is a Berkeley, California-based producer of energy gels and other performance sports nutrition products. The company was founded in 1994 by Bill Vaughan.

Corporate history[edit]

GU Energy Labs was founded in 1994 by biophysicist Bill Vaughan, based on products he developed for his daughter's athletics.[1][2] It was named GU as a play-on-words for "goo" due to the consistency of energy gels.[2] Bill's son Brian Vaughan now runs the company.[2] In June 2011, GU Energy Labs moved its operations and 50 employees from a 13,000-square-foot (1,200 m2) space to one with twice as much floor space in Berkeley's 4th Street shopping district.[3][4] As part of the move, the company's operations, which were previously spread among multiple buildings, were consolidated and its shipping operations were taken in-house.[4] In 2013, in conjunction with the Challenged Athletes Foundation, GU Energy Labs helped raise money for prosthetic legs for children.[5]


GU Energy Labs produces sports nutrition products, intended to increase the endurance of athletes.[6] It produces and markets energy gels that include carbohydrates, amino acids, electrolytes and caffeine.[7] It also has caffeine-free versions.[8] Gel packets come in different flavors, such as blackberry, chocolate, mandarin orange,[8] and peppermint stick.[9] They have a sticky gooey consistency.[10] Other products produced by GU Energy Labs include energy chews, drink mixes (called "brews"), brew tablets, and a Roctane Ultra Endurance line that includes an energy drink mix and gel.[11]


The Chicago Tribune said the vanilla-flavored products, like most energy gels, tasted "weird".[10] A reporter for The Oregonian said the flavors were "hit-or-miss", but the peppermint flavor was a "bulls-eye" for his tastes.[9] In comparison to other gels, GU Energy Labs products have a thicker consistency and a stronger flavor.[8]
