Diet Mountain Dew Overview

When it comes to taste, Diet Mountain Dew stays close to the original. It's got a lemony taste with a touch sweet. They make it with a mix of things like artificial sweeteners, citric acid, natural flavors, and other ingredients. A key sweetener in Diet Mountain Dew is aspartame. Aspartame is super sweet - about 200 times sweeter than regular sugar! The FDA and other official groups say aspartame is okay to consume, but some people may be sensitive to it and may not feel well after drinking it, such as headaches or dizziness.

Diet Mountain Dew also has caffeine, the stuff in some plants that gives you some energy and makes things taste better. The amount of caffeine you get depends on how much you drink, but if you have a 12-ounce can (that's about 355 milliliters), you're looking at about 54 milligrams of caffeine.

If you love Mountain Dew, but you're watching your sugar and calories, Diet Mountain Dew is an excellent option. You still get that familiar, citrusy Mountain Dew taste, plus a little caffeine kick, without all the sugar and calories.

If you like Diet Mountain Dew, you might also enjoy trying Diet Coke with Splenda, and Diet Pepsi.
