Mountain Dew is probably one of the more popular sodas for its high levels of caffeine. But how much caffeine is exactly in it? Let’s take a deeper look at how much caffeine you might be consuming.

**In a 12 ounce can, you get 55 milligrams of caffeine.****In a 16 ounce can, you get 17 milligrams more.**

**So either way, you get a decent amount of caffeine. But compared to an 8-ounce cup of coffee, it might appear to be a modest amount. **

**Now, let’s take a look at the bottles:**

Ounces / L | Caffeine (mg) |

20 ounces | 90 |

1 L | 150 |

1.5 L | 255 |

2 L | 270 |

Of course, a 20-ounce bottle of Mountain Dew will give you the same amount of caffeine compared to an 8-ounce cup of coffee.

Each of them contains **90 milligrams of caffeine. **

Taking a look at the **1-liter bottle will contain roughly 150 milligrams**. Interestingly enough, if you up the size it by a half-liter and you get a 100-milligram boost of caffeine.

Lastly, a 2-liter bottle has three times the amount of caffeine compared to a 20-ounce serving.

If you are drinking a 32-ounce large fountain soda of Mountain Dew, you’ll be taking in roughly the same amount of caffeine compared to a 1-liter bottle since it’s slightly the same size.

**Fountain sodas** will also come in different sizes. For example, an extra-large 64 ounce will top out at about **288 milligrams. **

That’s about 18 milligrams more compared to a 2-liter bottle, even though they are roughly the same size.

Ounces | Caffeine (mg) |

12 | 69 |

16 | 92 |

**Surprised?** You probably are. But those are just the cans.

How much caffeine is there in 20-ounce and 2-liter bottles?

**Let’s take a closer look:**

20 oz | 115 |

2 L | 385 |

In a 2 liter bottle, you get well over triple the amount.

How crazy is it that Pepsi Zero in a 2-liter bottle has 100 milligrams more than Mountain Dew?

Sounds pretty crazy considering a lot of people assume that Mountain Dew is jam-packed with caffeine.

## Is 92 mg Of Caffeine A Lot?

**92 milligrams**of caffeine doesn’t seem like a lot.

In fact, it’s exactly what you’ll get in an 8-ounce cup of coffee or a 16 ounce can of Pepsi Zero.

According to the Mayo Clinic, adults can contain 400mg of caffeine on a daily basis. **That is considered a safe amount. **

However, a safe amount of caffeine that adolescents can safely consume is around 100mg.

**So at 92mg,** it might be just enough per day for someone who is between the ages of 13 to 17. Depending on the age of the person, the safe amount of caffeine might vary. However, if you are sensitive to caffeine, then you may want to consider consuming low amounts or none at all.

## How Much Caffeine Is Too Much?

Persons that are aged 13 to 17, 100mg of caffeine is considered enough. But what if you consume too much caffeine.

**There are some side effects that**you may experience as a sign of going over the daily limit. Here’s what you might experience for side effects: anxiety, insomnia, muscle breakdown, digestion issues, fatigue, high blood pressure, rapid heart rate, and frequent urination.

It’s important to **keep a close eye on how much caffeine** you need to consume on a regular basis.

For example, if you are a healthy adult you can be able to consume multiple 12-ounce cans of soda in order to reach that amount. That depends on the kind of soda that you’ll be drinking, the size of the container, and the amount of caffeine it contains.

For example, to get near the daily limit an **adult could drink six 12 ounces of Pepsi Zero.**

For an adolescent, one can will likely be enough since it will reach their daily limit.

You may also go through some symptoms of caffeine withdrawal with a headache being one of the more common symptoms.
