An energy drink gets most of its ‘energy boosting’ qualities from an ingredient called ‘Caffeine’. Energy drinks are also known to be one of the most popular dietary supplements for teens and young adults in America.
To answer the question: Caffeine is one of the most important ingredients in an energy drink, usually around 70-240mg per 16fl oz. serving. There are also products called ‘energy shots’ which are smaller versions that contain 113-200mg of caffeine.
There are a ton of benefits caffeine can offer. However, some brands would exceed the said amounts for their drinks which would fit the liking of people with higher caffeine tolerance.
Caffeine can be sourced from many different ingredients to offer more benefits other than boosting your energy levels. All of those mentioned will be explained throughout this article. With that, I advise you continue reading to learn more.
Let’s jump right into it.
Where Does Caffeine Come From?
It’s said that caffeine is sourced naturally from some plants such as cocoa beans, kola nuts, tea leaves, and cocoa beans. On top of these are guarana seeds, yerba maté, guayusa, and yaupon holly.
Though I’ve mentioned many, I’ll focus on the most common sources of caffeine: Guarana seeds and tea leaves.
Guarana is widely used as a caffeine source in energy drinks. It also has theophylline and theobromine which are other stimulants related to caffeine. On top of this, it offers tannins, saponins, and catechins which are antioxidants as well.
This ingredient has the highest caffeine content in plants since it’s 3.6-5.8% by weight. To compare, coffee offers less since it’s only 2%. To add up, 50-75mg from Guarana can give you a ton of health benefits and there’s no instilled maximum amount you can take.
With what was mentioned above, before consuming this ingredient I suggest you consult a doctor first to clarify what your body needs.
Tea leaves are another caffeine-induced ingredient. It naturally comes from a tea plant called Camellia sinensis.
The caffeine content in tea leaves is 3.5%, which is close to the amount in Guarana seeds. In order to extract the caffeine from tea leaves, you would need to brew it.
Whenever caffeine is brewed in hotter water, more of its caffeine will come out. On the other hand, when cold, little will seep out of the ingredient. It’s said that exceeding the 3-4 cups or 710-950ml of tea may lead to negative effects, so it’s best to stay under it.
One example of an energy drink with both of the ingredients mentioned is Guru Energy Drink, which has organic guarana seed extract and organic tea leaf extract.

How Does Caffeine Work?
Caffeine works as a stimulant to your central nervous system, heart muscles, and blood pressure. Moreover, it also helps increase the flow of your urine.
Once caffeine takes effect in the central nervous system, it increases your alertness. With that, you’ll gain more energy and you’ll feel much more awake.
In the digestive and excretory systems, it increases the acid in your stomach thus leading to problems when you consume too much. The extra caffeine will then get excreted in your urine, which is why you immediately feel the need of going to the restroom.
Lastly, in the circulatory and respiratory systems, caffeine goes into the bloodstream after a couple of hours since intake. This stimulant will likely increase your blood pressure and pump your adrenaline thus increasing energy levels.

Caffeine sensitivity differs from person to person. For instance, you might feel an adrenaline rush when consuming the stimulant while others don’t. Moreover, you may also experience other side effects as well.
