The Key Ingredients in Boost Energy Drink

Some of the key ingredients include:


Caffeine is the primary energy-boosting ingredient in Boost. It is a stimulant that blocks adenosine receptors in the brain, reducing fatigue and promoting wakefulness and alertness. A 250ml can of Boost contains 80mg of caffeine, similar to a cup of coffee.


Taurine is an amino acid that is thought to enhance the effects of caffeine. It helps regulate cell volume and is believed to have antioxidant properties. Taurine may also improve mental focus and concentration.

B Vitamins

Boost contains several B vitamins including B3, B5, B6, B12. These water-soluble vitamins are essential for converting food into energy and supporting the nervous system.


This is a naturally occurring compound produced by glucose metabolism. It is thought to provide additional energy and improve mental performance. However, more research is needed on its effects.

Guarana Extract

Guarana is a plant native to South America. Its seeds contain caffeine and related stimulants like theophylline and theobromine. Guarana provides an additional energy boost.

How the Ingredients Work Together

The combination of caffeine, taurine, B vitamins, guarana, and other ingredients in Boost work synergistically to provide both physical and mental energy.

Caffeine is the primary energy booster, while taurine enhances its effects and supports mental focus. B vitamins help convert carbohydrates to glucose, providing fuel for the body and brain. Guarana seeds provide additional natural stimulants to prolong the energy kick.

Together, these ingredients help improve alertness, concentration, and stamina. The caffeine and guarana provide quick energy, while the B vitamins and taurine promote sustained energy release and prevent crashes later on.

Potential Side Effects

While generally safe in moderation, Boost drinks do have some potential side effects to be aware of:

  • Anxiety, jitteriness, rapid heartbeat – Too much caffeine can cause an energy crash later on
  • Dehydration – Caffeine has a mild diuretic effect
  • Headache, irritability – If you have caffeine sensitivity
  • Insomnia – Consuming late in the day can disrupt sleep

To avoid side effects, limit intake to 1 can per day and avoid other caffeinated drinks. Stay well hydrated and don’t drink Boost too late in the afternoon or evening. People sensitive to caffeine may want to avoid Boost altogether.

How Many Calories, Sugar, and Caffeine Does Boost Energy Drink Contain?

Boost Energy drinks contain around 55-58 calories per 250ml can. The sugar content is approximately 12-13g per 250ml can.

The caffeine content of Boost Energy drinks is:

  • 30mg per 100ml for the regular Boost Energy drinks
  • 45mg per 100ml for the Boost Iced Coffee drinks
  • 60mg per 100ml for the Boost Coffee Double Espresso drink
  • 40mg per 100ml for the Boost Iced Mocha drink

So a typical 250ml can of Boost Energy drink contains around 70-80mg of caffeine.

Is Boost Energy Drink Sugar-Free?

Boost does offer a sugar-free version of their Original energy drink in 250ml cans. This Sugar Free Original Boost Energy contains less than 0.5g of sugar per 100ml.

Other sugar-free options from Boost include:

  • Boost Energy Cherry 250ml
  • Boost Energy Exotic Fruits 250ml
  • Boost Energy Red Berry 250ml and 500ml

Is Boost Energy Drink Vegan?

Yes, all of the Boost drinks (except their Boost Iced Coffee range) are suitable for vegans, as they do not contain any animal products or by-products.

The ingredients in Boost Energy drinks are vegan-friendly, including the taurine used. The drinks are also free from gluten, nuts, and alcohol.

So vegans can safely consume Boost’s range of energy drinks including Original, Sugar Free, Cherry, Exotic Fruits, Red Berry, Mango, and Fruit Punch flavors.

How much Boost energy drink should you drink per day?

Boost energy drinks contain caffeine and other stimulants that can provide an energy boost. However, consuming too much caffeine can cause side effects like anxiety, jitteriness, rapid heartbeat, and sleep issues.

The recommended maximum daily caffeine intake for healthy adults is 400mg. Since Boost energy drinks contain 30mg of caffeine per 100ml, drinking more than 1.3 liters (44oz) per day could exceed the recommended limit.

To avoid side effects, it’s best to limit your intake of Boost energy drinks to 1 can or bottle (250ml) per day. Consuming more than this amount is not advised, especially for sensitive groups like children, pregnant women, and individuals with heart conditions.

If you do choose to drink more than one Boost energy drink per day, be sure to monitor yourself for any adverse effects like insomnia, nervousness, or an irregular heartbeat. And stay hydrated by drinking plenty of water as well. Moderation is key when it comes to caffeinated beverages.

When is the best time to drink Boost energy drink?

The best time to drink a Boost energy drink depends on your reason for consuming it:

  • Before exercise – Drinking a Boost 30-60 minutes before your workout can enhance your athletic performance by increasing alertness, endurance, and focus. The caffeine and carbohydrates provide an energy boost.
  • Mid-morning energy – A Boost energy drink around 9:30-11:30am can give you a lift if you’re feeling tired and need to be productive at work. The effects typically last about 5-6 hours.
  • Early afternoon – Having another Boost around 1:30-3:30pm can help beat the mid-afternoon slump and give you energy to power through the rest of your workday.
  • Night shift work – Moderate caffeine intake from Boost may help night shift workers stay alert and focused. But limit intake to early in your shift to prevent sleep issues.

No matter when you choose to drink it, allow time for the Boost to kick in before any important mental or physical activities. And stay adequately hydrated by drinking water too.

Can you drink Boost energy drink before bed?

It is not recommended to drink Boost energy drinks before bedtime.

Boost contains caffeine, which is a stimulant that can make it harder to fall asleep if consumed too close to bedtime.

Experts recommend stopping all caffeine intake at least 6 hours before your intended bedtime. This allows enough time for the caffeine from Boost to be metabolized and clear your system so it doesn’t disrupt your sleep.

Drinking Boost too late in the day can lead to sleep issues like:

  • Difficulty falling asleep
  • Frequent awakenings during the night
  • Overall less restful sleep
  • Daytime drowsiness the next day

The best practice is to avoid all caffeinated beverages like Boost for 6-8 hours before bed for optimal sleep quality. Plan your last Boost so you can meet this cutoff.

The Origins of Boost: From University Project to Global Brand

Boost Drinks Limited is the British company behind the popular Boost energy drink brand. Founded in 2001 by entrepreneur Simon Gray, Boost Drinks aims to provide good-tasting, affordable energy drinks through convenience stores, independent retailers, and forecourts across the UK.

Based in Leeds, England, Boost Drinks started with a £30,000 bank loan. Within the first year, founder Simon Gray had already paid back the loan in full. The company originally launched under the name Blast UK Limited before rebranding to Boost Drinks Limited in July 2001.

Boost Drinks then rapidly expanded from solely serving the UK market to exporting its drinks to over 30 countries globally. Some of Boost’s major international markets include Spain, the Middle East, Australia, and South Africa.

As a challenger to mainstream energy drink brands, Boost Drinks has focused on affordable pricing, wide distribution, and establishing itself as a recognizable value brand. The company has partnered with leading UK wholesalers and symbol groups to make its drinks widely accessible.

After 20 years of strong growth and brand building, Boost Drinks was acquired by the UK beverage company A.G. Barr in late 2022 for £20 million. However, Boost continues to operate as a standalone business maintaining its own brand identity and distribution strategy.
