Tasty, energising and full of supplemental ingredients, the best energy drinks will quench your thirst while giving you an all-round boost

While they may sometimes get a bad rap, the best energy drinks have plenty of positives. They offer an alternative stimulant for those who don’t enjoy the taste of coffee – or its high price – when out and about. Energy drinks also tend to come in a variety of tasty and interesting flavours, offer a significant caffeine boost that even some stronger coffees fail to match and are easily portable and storable for long periods of time. Another interesting thing about energy drinks is the tight-knit communities and fan-followings they sometimes develop due to their fun, maximalist aesthetics and sponsorship of extreme sports and up-and-coming music scenes.

Beyond all that, they contain a range of energy-boosting and, sometimes, health-boosting ingredients, which we will guide you through in our handy buying guide below. A little further down the page, you’ll find mini-reviews of our favourite energy drinks, where we break down the flavours and key ingredients that ensured they made it onto our list. So, say goodbye to sluggishness, it’s time to get energised.

Best energy drink: At a glance


How to choose the best energy drink for you

Energy drinks have a lot of supplemental ingredients – what do they all do?

Beyond caffeine, energy drinks pack in many supplemental vitamins, sugars and other ingredients to try to increase your mental performance and energy. It can be difficult to keep track of all these ingredients and their different properties, so we’ve assembled a handy glossary:

B vitamins, such as riboflavin, niacin and B12, help our bodies convert carbohydrates into glucose, which in turn gives us energy. B vitamins also help with a range of complex processes, such as the metabolisation of proteins and fats.

BCAAs, or branched-chain amino acids, are named for their branching chemical structure. The body cannot synthesise BCAAs, so they must be taken in as part of your diet or in supplementary form. They’re important for muscle and skeletal growth and are thought to improve athletic performance and mental stimulation, although further study is needed to prove the latter claims.

Ginseng, in its fresh form, is a type of root popular in traditional Chinese medicine. It’s widely taken for its antioxidant properties and possible increases in mental performance and energy levels, although many of its health benefits remain unproven.

Guarana is a plant native to the Amazon and naturally contains caffeine. Many energy drinks contain guarana extract for caffeination or to supplement caffeine levels.

L-carnitine is a nutrient that helps transport fatty acids to your cell’s mitochondria, where they can be turned into energy. While we’re still learning about the various roles it plays in the body, it’s generally agreed that L-carnitine contributes to brain and heart function, muscle movement, and many other bodily processes. Vegans tend to produce lower amounts of L-carnitine, so supplemental amounts of this may be beneficial for those avoiding animal products.

Taurine is important to many of the body's metabolic processes and helps improve cardiovascular health. It’s also thought to have antioxidant properties. This amino acid occurs naturally in meat, fish and dairy products. There isn’t much consensus as to the positive effects of taurine, though some studies suggest it improves athletic performance, as well as mental performance when consumed alongside caffeine.

Vitamin C famously helps stave off scurvy, with citrus fruits being a good source. It’s also involved in tissue repair, collagen formation and the production of l-carnitine, among other things.

Are energy drinks safe?

Energy drinks, like most things in life, are perfectly safe when consumed in moderation. That being said, their high caffeine content can be hazardous for those with pre-existing heart conditions, pregnant women and younger children. For the best safe consumption advice, always refer to the label or can and follow the manufacturer’s guidance and instructions.

Another factor to consider when consuming energy drinks is that they tend to be high in sugar, which, similar to caffeine, is fine in moderation. To be mindful of this, however, we’ll also link to sugar-free versions of our favourite drinks where available.
