The Complete Guide to Pre-Workout Supplements

Written By UK Fitness Events

Pre-workout supplements are a big thing in the fitness community. They promise to boost energy, enhance performance, and ensure you get the most from your workouts. But what are they exactly? How should they be used? And which ones are considered the best? In this article, we’ll delve into the world of pre-workout supplements and address these questions in great detail.

What are Pre-Workout Supplements?

Pre-workout supplements, as the name suggests, are products taken before a workout session. They’re a blend of various ingredients meant to increase your stamina, energy, and overall athletic performance. Pre-workouts often contain a mix of amino acids, caffeine, creatine, and beta-alanine, among other elements.

Amino acids are the building blocks of proteins, and some are considered essential for your body to function correctly. Two of the most commonly used in pre-workout supplements are BCAAs (Branched Chain Amino Acids) and L-arginine. BCAAs help preserve muscle glycogen stores, potentially reducing fatigue, while L-arginine aids in boosting nitric oxide production, promoting better blood flow to the muscles.

Caffeine is a well-known stimulant included in many pre-workouts for its ability to increase alertness and delay fatigue. Creatine is another prevalent ingredient. It helps increase muscle strength and size and can improve high-intensity exercise performance. Lastly, beta-alanine is added to counteract muscle fatigue, allowing for more prolonged and more intense workouts.

The Science Behind Pre-Workout Supplements

While the primary ingredients in pre-workout supplements like caffeine, creatine, and beta-alanine have individually been backed by numerous studies, the science behind the specific blends in pre-workout products can be murkier.

Many pre-workout manufacturers make claims about their products’ effects, but it’s important to remember that the supplement industry is not as tightly regulated as pharmaceuticals. Always check for third-party testing and seek out evidence-backed ingredients when choosing a pre-workout supplement.

Some reputable bodies such as NSF International and Informed Choice can provide certification that products have been tested and verified for safety and ingredient accuracy.

How to Take Pre-Workout Supplements

The method of consuming pre-workout supplements is simple: mix the recommended dose with water and consume it about 30 minutes before your workout. However, understanding how to incorporate them into your routine effectively requires a bit more insight.

First, don’t rely solely on pre-workouts to fuel your performance. Real, wholesome foods should form the foundation of your nutrition. Think of pre-workouts as the cherry on top, giving you an extra boost when needed.

Second, remember that everyone’s tolerance for pre-workouts is different. Start with a smaller dose to assess how your body responds, and adjust accordingly. Avoid taking pre-workouts later in the day, as the caffeine content can interfere with your sleep.

Lastly, be aware of the potential for developing a tolerance to pre-workout supplements. If you take them consistently over a prolonged period, their effectiveness may diminish. To avoid this, consider cycling your use – taking them for a few weeks, then taking a break before starting again.

Which are the Best Pre-Workout Supplements?

Determining the “best” pre-workout supplements depends largely on individual preferences, budget, and fitness goals. However, a few standout products have been widely praised for their efficacy and ingredient profiles.

Legion Pulse: This product tops many lists due to its clean, clinically-dosed ingredients, and the absence of artificial sweeteners and colouring. It features a balanced mix of caffeine, theanine, beta-alanine, and citrulline, promising a significant energy boost without the dreaded “crash.”

Cellucor C4 Original: A fan favourite, C4 Original offers a blend of caffeine, creatine nitrate, and beta-alanine. It’s also well-regarded for its range of flavours and affordability.

Optimum Nutrition Gold Standard Pre-Workout: Another crowd-pleaser, this product contains an array of beneficial ingredients including creatine monohydrate, beta-alanine, and L-citrulline, and is free of banned substances.

Transparent Labs PreSeries BULK: Aimed at those seeking to build muscle, this pre-workout packs a hefty dose of citrulline malate, beta-alanine, BCAAs, and taurine, among other ingredients. As its name suggests, it prides itself on its transparent, no-filler ingredient list.

Always consult with a healthcare professional before starting any new supplement regimen. Our friends at Barbend also have a couple of great recommendations on pre-workouts.

Possible Side Effects of Pre-Workout Supplements

While pre-workout supplements can be beneficial, they’re not without potential side effects. The caffeine content can lead to symptoms like jitteriness, increased heart rate, and trouble sleeping if taken too late in the day. Overuse can also lead to caffeine dependence or withdrawal symptoms.

Some individuals may experience tingling or flushing from beta-alanine, while others may have digestive upset from large doses of certain amino acids. Excessive intake of these supplements can sometimes lead to more severe health issues, like kidney damage, especially in those with pre-existing conditions.

Natural Alternatives to Pre-Workout Supplements

Pre-workout can be expensive, which is why it is always good to look for the best pre-workout on a budget. Alternatively, if you’re not keen on the idea of taking a pre-packaged pre-workout, there are natural alternatives that can still give you a performance boost. A cup of black coffee can provide a caffeine hit, and pairing this with a banana can provide a combination of quick and slow-release carbs for sustained energy.

Beetroot juice is another popular choice as it’s naturally high in nitrates, which can help increase blood flow during exercise. A small snack with a balance of protein and carbohydrates can also provide a suitable energy boost. Remember, everyone’s body is different, and what works for one person might not work for another. It’s all about finding what suits you and your workout best.


Pre-workout supplements can be a potent tool in your fitness arsenal. They offer a variety of benefits designed to help you optimize your workouts, from increased energy to enhanced muscle strength. But remember, they are just one piece of the puzzle. Real food, adequate hydration, and proper rest all play a significant role in your performance and recovery. Whether you’re a casual gym-goer or a professional athlete, understanding pre-workout supplements and how to use them effectively can make a substantial difference in your fitness journey.
