Mountain Dew MDX (previously known as "Flavor #516" and "Mountain Dew X") was a Mountain Dew energy drink variant that lasted from November 2005 and until mid-2007. It was PepsiCo's attempt to compete with Coca-Cola's Vault energy drink.

Description

MDX was the original Mountain Dew flavor formula, but with ingredients added such as maltodextrin, ginseng, taurine, d-ribose, and guarana to give it the energy drink kick. It also had a higher caffeine content than original Mountain Dew, despite having the same basic taste and color.

Trivia

  • This was one of many attempts at a Mountain Dew energy drink. See "Similar Flavors" in the infobox for more.
  • MDX was the pioneering flavor for the Sidekick bottle design, which PepsiCo would incorporate into most of their 20 oz. bottle designs later on in the 2010s, replacing the dome-like design.
