I want an amazing workout every time…

Now you can.

Having consistently high energy levels would be great but in today’s increasingly busy world, that isn't always possible. Sometimes it can feel like there aren't enough hours in the day. The result of all that rushing around can mean a workout that doesn’t feel like you’ve done yourself justice.

If this sounds all too familiar, then check out The Energy Booster for. Wave goodbye to running on empty, and hello to a new lease of life. Formulated by leading nutritionists, The Energy Booster is a pre-workout game-changer that helps you get the most out of each and every single workout whether it’s in terms of speed, strength, power or endurance.

Awarded best pre-workout in the Men’s Health Sports Nutrition Awards. Each serving contains 5g of energy-boosting amino acids, along with natural stimulants such as maca root and guarana.

It’s what’s inside that matters

Research-backed natural ingredients, nootropics and adaptogens. Scientifically proven to boost energy, increase endurance and stamina, and safeguard lean muscle during exercise.

Per Serving:

BCAA Complex (5g): Of the 20 amino acids that make up the thousands of different proteins in your body, nine are considered essential amino acids, meaning they must be obtained through your diet. Three of these nine are branched-chain amino acids (BCAAs): leucine, isoleucine and valine. These are the most important amino acids for muscle growth and maintenance. You can find them here in an optimal 2:1:1 ratio.

Citrulline Malate (2g): This is L-Citrulline (an amino acid) combined with malic acid (an organic salt). Citrulline malate can improve aerobic and anaerobic performance during prolonged exercise by reducing fatigue and increasing nitric oxide in the body. This relaxes blood vessels and increases blood flow and oxygen to working muscles.

Maca (1.25g): Reduces effects of physical and mental stress, and increases energy and libido. Grown for more than 2,000 years in the highest mountains of Peru, maca has recently found widespread popularity as an adaptogen. These are a group of natural ingredients that support the body's ability to deal with stress.

Beta Alanine (1.2g): When you exercise, metabolites accumulate in the muscles, causing pH levels to drop, resulting in muscle fatigue. Carnosine can help reduce this acidity but the amount of carnosine made in the body depends on the amount of beta alanine available, and it's only when there's excess beta alanine that carnosine levels can increase to offset fatigue and aid performance.

Guarana (100mg): An Amazonian fruit considered to be an elixir of long life. In addition to the stimulating action of its caffeine content, other beneficial effects have been attributed to guarana’s alkaloid content. These include improved alertness, reaction time, speed of information processing, memory, mood and performance in physical exercises.

Caffeine (71mg): The value of caffeine on mental and physical performance has been well-established. Research evidences positive effects on improving alertness, mood, cognitive function, fat oxidation, and exercise performance.

Vitamin B Complex*: For the reduction of tiredness and fatigue and normal energy-yielding metabolism. They also play a role in maintaining hair and skin health, and a regulated nervous system. There are eight essential B vitamins: thiamin, riboflavin, niacin, pantothenic acid, vitamin B6, biotin, folic acid and vitamin B12. We bring all eight together to ensure you get the daily recommended intake of each.


*%NRV (Nutrient Reference Values) are guidelines on daily amounts of vitamins and minerals to be consumed to maintain a healthy diet.

After trying quite a few different pre-workouts, I always found many of them to taste too sweet. The Energy Booster doesn’t give you that “over-sweetened” taste and the pineapple flavour is very refreshing especially during intense HIIT sessions. Another great thing I love about this energy booster is how quickly it dissolves… no waiting around!

Please ship internationally!

Can’t live without!

It’s tastes good and it makes a huge difference when I workout! It loads you with energy and You can just get on with your tasks. Definitely recommend to people who needs and extra boost, especially in difficult times like we are living right now.

A recommended boost

This product does exactly what it says on the package. A great energy boost before a workout and feels natural. The texture is slightly grainy even when mixed in well, but the flavour is pretty nice and it boosts energy levels before a workout.


I don't like to eat before a workout, I feel bloated and sluggish, I love this product though. I feel the energy within 10 minutes, which is perfect as I'm able to drink, start my warm up and power through the rest of my workout. I get a gentle itch if I haven't moved within 15 minutes which is a great way to kick my lazy bum into gear. Other Energizer's I have found make me itchy even if I am moving, so this was perfect. The taste and smell took me a while to get used to (only reason for the 4 stars) I had to heavily dilute for the first few weeks.

Natural Energy & Focus

I like how natural this product is compared to other pre-workout drinks, and it doesn't have too much caffeine. It does make me a little itchy if I drink it and don't immediately start moving. That said, I've also used it for a boost while writing a masters thesis and it helped me focus. Drinking it when working out, if I'm doing a hard lifting session, it doesn't always sustain my energy through to the end. Its pros far outweigh its cons, though, so I'll keep using it unless I find a better natural alternative.

Not yet 100% convinced

I have only used the product a few times, but I seem to be getting more energy from different pre/intra workout powders. I workout 6 days a week with sometimes double days, so my body sometimes craves that extra bit of energy to push through the last reps. Opted for this one as I hooked to the Health Protein powder and Tone Capsules. Still have to get used to the pineapple taste as well. Have definitely not given up on the product yet, but tbc!
