Keeping track of your caffeine intake can help you regulate your healthy habits better. For example, sodas have become an everyday beverage in households and notoriously contain high amounts of caffeine. 

Most locally available sodas do contain an excessive amount of caffeine. You can name any from Pepsi, Coke, or Dr. Pepper – they all contain caffeine. However, the caffeine amount varies according to manufacturing, coloring, and flavoring. 

So whether you’re looking for soda drinks containing a caffeinated punch for you or cutting down on your caffeine addiction – this article will answer all your queries. 

Top 10 Sodas With The Most Caffeine

Normal caffeine amounts in sodas can differ depending on the soda’s variants and the country you’re in. However, we’ve curated a comprehensive list covering most variants to help you regulate caffeine intake. 

  1. RedBull

Although some people might say energy drinks differ from soft drink sodas, the truth is that they fall under the same umbrella as soft drinks. For example, Red Bull, one of the most famous energy drinks, is higher than most sodas in caffeine content and sugar, containing a whopping 30 mg of caffeine per 100ml. 

A study conducted in 2001 suggested that regular consumption of Red Bull hinders your overall cognitive performance. 

  1. Mountain Dew

Despite being a Pepsi product, citrus-flavored Mountain Dew contains more caffeine than Pepsi. Mountain Dew contains 15.8 mg per 100ml of caffeine. 

Mountain Dew also contains more calories and sugar than other famous sodas. So if you’re looking to cut down on your caffeine or sugar intake, Mountain Dew won’t help you on that journey. 

  1. Diet Coca-Cola

There’s a misconception around diet variants of Coca-Cola that, apart from sugar, they cut down on caffeine as well. However, the truth is quite the opposite: Diet Coke contains 50% more caffeine per serving than regular Coke.

Diet Coke contains 12.26 mg of caffeine per 100 ml, which leads us to conclude that a single can of Diet Coke has an incredible 46 mg of caffeine!

  1. Dr. Pepper

America’s beloved drink Dr. Pepper also contains plenty of caffeine. This fruit-flavored delicious soft drink contains about 11.8mg of caffeine per 100ml, which is a bit on the higher side as far as soft drinks go. The good news, however, is that this drink contains fewer calories and less sugar than Pepsi and Coca-Cola. 

  1. Pepsi

Caffeine is often the perfect deal breaker for those choosing between Pepsi and Coke.  Most individuals aren’t aware that Pepsi is more caffeinated than Coke, as it contains around 10.7mg of caffeine per 100ml. 

Despite that, the caffeine amounts between regular Coke and Pepsi don’t differ much. 

  1. Diet Pepsi

The diet variant of Pepsi takes the opposite approach to Diet Coke. This means that the diet variant of Pepsi contains less caffeine than your classic can of Pepsi. Diet Pepsi contains only 9.86 mg of caffeine per 100ml. 

However, experts warn against the careless and regular consumption of diet sodas. A study published in 2012 elaborates upon how diet soft drink consumption leads to vascular diseases and health problems in old age. 

  1. Coca-Cola 

Despite Coca-Cola being among the most popular soft drinks in the world, most individuals aren’t aware of the amount of caffeine it contains. If you’re one of those people, you might be surprised that Coca-Cola contains 8.5mg of caffeine per 100ml. 

This means that your commonly available can of Coca-Cola contains 28.5 mg of caffeine. Coca-Cola was initially made for those looking to abstain from alcohol, so it makes sense regarding why the caffeine content is relatively high. 

  1. Moxie 

Moxie, a soda that’s become outdated, contains about 6.78 mg of caffeine per 100 ml. Although this beverage has recently lost its popularity, it happened to be one of the first mass-produced sodas in the US. So you can still find this brand readily available if you live in the US.

  1.  Sunkist

Sunkist is manufactured by the same company that manufactures Dr. Pepper. As a result, Sunkist has the same refreshing and lemony flavor profile as 7-Up. Citrus-flavored drinks like 7-Up and Sprite usually contain less caffeine than sodas such as Coke or Pepsi, but Sunkist is an exception. 

This summer beverage contains 5.35 mg of caffeine per 100ml. This figure is lower than other soft drinks available in the market but higher than its citrus-flavored competitors. 

  1. Big Fizz Cola 

Similar to the likes and tastes of Coke and Pepsi, Big Fizz Cola contains 5.2 mg of caffeine per 100ml. However, this is pretty average as far as sodas go, and the caffeine content isn’t a cause for concern if you like this classic soda. 

Best Caffeine-free Sodas

The caffeine content in most popular sodas is nothing to fret about, as there are caffeine-free alternatives available all over the globe. One of the best ways to figure out which soda is caffeine-free is to understand the flavor profiles and colors of most caffeine-free drinks.

Colorless sodas such as Sprite, 7-Up, and Sierra Mist are typically caffeine-free. Their diet variants also do not contain any caffeine. In addition, Canada Dry Brand and Schweppes ginger ale contains natural ginger extract and is also wholly caffeine-free. 

Carbonated water, such as seltzer water, tonic water, and sparkling water, is caffeine-free. Despite the flavors not being as intense as a can of Coke, carbonated water is an excellent option if you want to cut down on sugar and caffeine intake. 

Which Soda Has More Caffeine, Coke or Dr. Pepper?

Coke and Dr. Pepper are some of the most widely consumed brands of soft drinks in the US. But if you’re curious about which one contains more caffeine, the answer is Dr. Pepper. 

Coke contains 33.9 mg of caffeine per 12 oz, while Dr. Pepper contains 42.6mg per 12 oz. This is not that stark of a difference but if you’re being cautious about your caffeine intake, definitely choose Coke. 

The diet variants of Coke and Dr. Pepper also contain a substantial amount of caffeine but less added sugar. 

Which Soda Has More Caffeine, Coke or Sprite?

Coke or Sprite are usually not drunk interchangeably. Some believe that Sprite is healthier than Coke and use it as medicine for nausea. As far as their caffeine contents go, Coke is more caffeinated.

Sprite does not contain caffeine, making it the perfect option for reducing caffeine intake. In addition, Coke and Sprite have similar carbonation levels, and Sprite can be a suitable substitute for those looking to move away from drinking sodas altogether. 

Is Caffeine A Drug?

While this may be shocking to some individuals, caffeine is a stimulant drug. It speeds up the messages your body delivers to your brain, which is why it often causes symptoms such as excessive alertness, loss of appetite, and insomnia. 

Caffeine content can range dramatically between soft drinks, so it’s always best to check the ingredient label to ensure the range is within your health requirements. 

Is Having Caffeine Daily Safe?

Unfortunately, there’s no safe or recommended amount for caffeine consumption. As drug usage carries potential risks, it’s always better to stick to moderation. In addition, caffeine should not be consumed by children, pregnant or breastfeeding mothers, or those suffering from heart conditions. 

Sleep disorders and anxiety can be a result of prolonged overconsumption of caffeine. Therefore, ensure you don’t reach for that can of Coke too often.

Can Caffeine Be Addictive?

Caffeine is addictive. It contains specific characteristics that can cause physical dependence. Usually, this dependency is not severe enough to be an alarming cause for concern. You don’t experience extreme physical withdrawal symptoms if you form a dependency. 

However, you may develop a tolerance towards caffeine. This means that you’ll need more caffeine after prolonged usage for it to have the same physical results. You may also experience cravings and moderate withdrawal symptoms if you go without caffeine. 

Consuming too much caffeine can cause cognitive defects such as insomnia and anxiety. Therefore, always check your caffeine intake to ensure it’s moderate and irregular. 

What Does Caffeine Do To The Brain?

Caffeine molecules penetrate the brain and block off specific receptors; this leads to an excessive release of the brain’s chemical known as dopamine. Dopamine release leads to physical symptoms such as alertness, concentration, and hyperactivity. 

This activity increase in your nervous system is acceptable if you’re consuming caffeine moderately. However, if these small doses cause a gradual dependency, your brain will start requiring more caffeine to achieve the same physical symptoms. 


While caffeine may not be the best stimulant to consume every day, there are always soda variants that are low in caffeine or contain zero caffeine. So whether you’re someone who enjoys having that caffeine punch with your meal or someone who likes to sip on a cold caffeine-free Sprite, you’re bound to come across the perfect soda for yourself!
