How Much Caffeine Is In Mountain Dew? [Bottles, Cans]

how much caffeine is in mountain dew

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.

So how much caffeine is in a can or bottle of Mountain Dew?

  • 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.

How Much Caffeine in Pepsi?

Mountain Dew is part of the PepsiCo.

Family. Now, we’ll turn our attention to the flagship beverage of the company.

So how much caffeine is in a regular Pepsi?

Let’s get started by taking a look at how much 12 and 16 ounce cans contain along with the various size of bottles.

Ounces Caffeine (mg)
12 37.5
16 50

One can of Pepsi contains 37.5 milligrams of caffeine. Its 16-ounce counterpart will have 13 milligrams more of caffeine, topping it to around 50 milligrams. Now, let’s take a look at what you can get in bottles.

Ounces/Liter Caffeine (mg)
20 63.3
1 L 104
1.5 L 160
2 L 212

As you notice, the caffeine strength in Pepsi is considerably lower compared to Mountain Dew.

So if you are looking for an alternative that will give you slightly less caffeine, then there’s a good chance that Pepsi might be the better choice when comparing the two.

How Much Caffeine Is In Pepsi Zero?

Pepsi Zero is one of the sugar-free alternatives to regular Pepsi.

This should not be confused with Diet Pepsi.

Is there a difference between regular Pepsi and Pepsi Zero when it comes to caffeine?

The answer actually might surprise you, so read on.

Ounces Caffeine (mg)
12 69
16 92

Believe it or not, Pepsi Zero has more caffeine compared to its regular counterpart. While a 12 ounce can of Pepsi has 38 milligrams of caffeine, a Pepsi Zero of the same size will nearly have double the caffeine at 69 milligrams. A 16 ounce can of Pepsi Zero comes in at 92 milligrams of caffeine. It should be noted that it has slightly more caffeine than a 20-ounce bottle of Mountain Dew.

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:

Ounces/Liter Caffeine (mg)
20 oz 115
2 L 385

There are two different sized bottles that Pepsi Zero comes in. A 20-ounce bottle will contain 115 milligrams of caffeine.

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?

Believe it or not, 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?

As mentioned, a healthy adult can be able to consume 400mg of caffeine on a daily basis.

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.

Final Thoughts On Caffeine in Mountain Dew Sodas

While Mountain Dew had long maintained a reputation of being a very highly caffeinated beverage, Pepsi Zero seems to topple it in terms of the levels and strength of caffeine.

Compared to that with regular Pepsi that has far less caffeine compared to both its sugar-free counterpart and Mountain Dew.

If you are a regular soda drinker, it’s important to keep track of how much caffeine you might be consuming.

Remember, if you are experiencing any kind of side effects you’ll know that you have consumed more than enough of the “safe” amount.

You’d actually surprised by how much caffeine a can or bottle of soda can contain compared to a small cup of coffee.

Now that you know how much caffeine is in each of these sodas, you might be considering new options of what you might drink from here on out.
