Frequently asked questions (FAQs)

People tend to have a lot of questions regarding pre-workout, especially as there are a lot of common misconceptions, but we're here to clear up some of the more typical queries you may have.

What are some common ingredients to look for in pre-workout?

Various companies utilise distinct formulations for their pre-workout supplements, making it challenging to discover an identical blend with matching components and proportions from another brand.

Caffeine stands out as a prevalent ingredient to be mindful of though, as higher caffeine content corresponds to elevated bursts of short-term energy. However, certain pre-workouts are designed without caffeine to accommodate individuals aiming to decrease their caffeine consumption.

Another common component is beta-alanine, which supposedly helps you withstand the 'burning' feeling you get when pushing your workout to failure, therefore allowing you to pump out a few more reps in each set.

Taurine is another one, typically found in energy drinks, although occasionally in pre-workout too. This is because it's perhaps best known for its potential to boost your energy levels and exercise performance, hence its use in pre-workout supplements.

The key to it all is to simply do your research. If you're unsure about any ingredients, use reliable sources to gain a better understanding of whether you should or shouldn't take them.

What are nitric oxide boosters?

If you come across ingredients such as l-citrulline then you are looking at a nitric oxide booster.

In theory, nitric oxide boosters increase blood flow to your muscles and, therefore, should improve your 'pump' during high-rep exercises.

L-citrulline, for instance, is the natural form of citrulline and its primary function is to boost nitric oxide levels which help dilate your blood vessels, meaning your muscles get more oxygen and nutrients which also combat fatigue.

How long does pre-workout last?


There is no one true answer to this question as the effects of pre-work will vary depending on your height, weight, tolerance to caffeine, and so on.

The majority of pre-workouts recommend consuming them anywhere from 30 to 45 minutes before exercising to reap the full benefits of the stimulants and to get the most out of your workout.

Thereafter, pre-workout can last between 3 to 6 hours depending on the person, meaning you should have plenty of time to complete even the most grueling and long workout whilst still feeling some effects of the supplement.

Should a beginner take pre-workout?

Pre-workout isn't for everyone, and as a beginner, you might find it to be overpowering, especially given some of the adverse effects of caffeine on your stomach.

With that being said, we'd recommend looking to improve factors like sleep, hydration, and your diet as the first port of call instead of turning to supplements to minimise tiredness and fatigue.

If you're still interested in taking pre-workout, then we'd suggest investigating the ingredients before picking one up, and make sure you stick to the recommended amounts in order to remain safe whilst taking them.

Can you take pre-workout supplements every day?

If you continually take pre-workout on a regular basis, your body can build up a tolerance to it, thus making it less effective.

Some pre-workouts recommend cycling them on and off in order to avoid building up a tolerance and, potentially, becoming addicted to the caffeine which comes with its own side effects such as increasing your blood pressure.
