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.
- Mountain Dew MDX was originally called Mountain Dew X. It was most likely to be the prototype name of MDX.
- This was only one of many attempts at a Mountain Dew energy drink. See Related 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.
