CRUNK!!! Energy Drink is a non-alcoholic energy drink that was co-created and launched in 2004 by Sidney Frank, creator of Grey Goose vodka and founder of Sidney Frank Importing Company (importer of Jägermeister), along with Lil’ Jon, the Grammy award winning artist and producer who is still onboard with Crunk as its Chief Brand Advisor.

In May 2007 Solvi Brands LLC, a privately held company, announced that it had purchased certain assets of Crunk LLC including the Crunk Energy Drink brand.

Crunk Energy Drink includes pomegranate juice, high fructose corn syrup, B vitamins, and a proprietary blend of herbs, including ashwaganda, Epimedium, white willow, skullcap, guarana, and ginseng.

Energy drinks are beverages whose producers advertise that they "boost energy". These advertisements usually do not emphasize energy derived from the sugar and caffeine they contain but rather increased energy release due to a variety of stimulants and vitamins.

In the UK, Lucozade Energy was originally introduced in 1929 as a hospital drink for "aiding the recovery;" in the early 1980s, it was promoted as an energy drink for "replenishing lost energy."

One of the first energy drinks introduced in America was Dr. Enuf who's origins date back to 1949, when a Chicago businessman named William Mark Swartz was urged by coworkers to formulate a soft drink fortified with vitamins as an alternative to sugar sodas full of empty calories. He developed an "energy booster" drink containing B vitamins, caffeine and cane sugar. After placing a notice in a trade magazine seeking a bottler, he formed a partnership with Charles Gordon of Tri-Cities Beverage to produce and distribute the soda. Dr. Enuf is still being manufactured in Johnson City, TN and sold sparsely throughout the nation.

Jonathan Smith (born January 27, 1971), better known by his stage name Lil Jon, is an American rapper, music producer, entrepreneur, and international DJ who was a member of the group Lil Jon & The East Side Boyz. Lil Jon formed the group in 1997, and the group released several albums between then and 2004. He then went solo and released a new album in 2010 called Crunk Rock.

Lil' Jon was born and raised in Atlanta, Georgia. He graduated from Frederick Douglass High School.

After working as a DJ for Atlanta night clubs, he started working for So So Def Recordings between 1993 and 2000. The group signed to the Atlanta-based Mirror Image Records and were distributed by Ichiban Records. In 1997, Lil' Jon & the East Side Boyz debuted with Get Crunk, Who U Wit: Da Album. It included singles "Who U Wit?" and "Shawty Freak a Lil' Sumthin'", the latter of which came out in 1998. Both singles charted on the Billboard Hot R&B/Hip-Hop Songs chart at No. 70 and No. 62 respectively. In 2000 Jon took part in starting up his own label BME Recordings and signed a distribution agreement with Norcross, Georgia based Southern Music Distribution. There he released his break through album titled We Still Crunk. Among the tracks on that project was the hit single "I Like Dem Girlz", which reached No. 55 on the R&B chart and No. 3 on the Hot Rap Tracks chart.
