Pre-workout ingredients and their effects
Pre-workout supplements contain a mixture of chemical compounds that have different effects on your body and brain. Understanding some of the common ingredients will help you choose the right products and get the right results.
Creatine Monohydrate - Muscle power supplement that helps to regenerate ATP - the main source of energy in muscle cells. This means you can train for longer at a more intense rate.
Beta-Alanine - Rebalances muscle pH and reduces levels of lactic acid, meaning you can train at your peak for longer. Beta-Alanine is a non-essential amino acid which fights off muscle fatigue while you're training.
L-Citrulline - Originally derived from watermelon, L-Citrulline is another amino acid commonly used in pre-workouts. L-Citrulline is converted to nitric oxide in the body which is used to increase blood flow and reduce blood pressure.
BCAAs - Branched Chain Amino Acids (BCAAs) are essential for muscle repair and reduce the breakdown of proteins. Including BCAAs in your pre-workout can help you build muscle mass quicker with less downtime between workouts.
Citrulline Malate - Similar to L-Citrulline, Citrulline Malate is useful for improved blood flow thanks to nitric oxide production. It also supports ATP production and can reduce lactic acid production.
Taurine - Taurine is an ingredient commonly used in energy drinks due to its ability to improve exercise performance. It can reduce muscle fatigue and is an effective hydration agent.

The best pre-workout for you will depend entirely on your own personal preferences and workout routine. For example, pre-workout supplements range from high-intensity stimulant-based products to stimulant-free muscle builders. If you are sensitive to stimulants or feel they’re not necessary for your workout routine, you might find stimulant-free pre-workout products are the best to get the results you’re looking for.
There are no proprietary blends used in products stocked on A-List Nutrition, meaning you have a clear understanding of the ingredients in every option to allow you to choose what’s best for your body before you order.
Recreational gym-goers may not always see the value in supplementing with pre-workout products and may often find that other stimulants like coffee are an effective way of boosting energy. However, pre-workout supplements benefit from the effects of multiple ingredients that are great at boosting energy, improving focus and building muscle. Therefore, these products are favoured by those looking to see fast, significant results from their workouts.
As a general rule, most stimulants like caffeine take around 20-30 minutes to kick in, so taking your pre-workout supplements at this time before a gym session is usually the best approach.
Caffeine can last for 3-5 hours in the body so it’s not always necessary to be in the gym 30 minutes after your supplements but you’ll also need to consider the lasting effects after you’ve left the gym, too. If you take stimulants late in the day, they could disrupt your sleep and sleep is essential for your body to repair, especially after intense workouts.
While there can be some side effects from high doses of ingredients often found in pre-workout supplements, including jitters, intestinal discomfort and bloating, but generally, pre-workout supplements are safe for daily use.
On the other hand, consuming caffeine and other stimulants daily can encourage a build-up of tolerance and dependence on the substances. If you find your stimulant pre-workout products don’t have as much effect after a couple of week’s use, try switching to a stimulant-free blend to help stabilise your body’s reaction to the ingredients.
Most pre-workout products will provide the best benefit in the gym after around 30 minutes so taking them later than this could mean you don’t get the most from your workout. You’ll also need to think about how late in the day you take pre-workout as the boost in energy could keep you up at night if taken too late.
Pre-workout supplements contain a variety of ingredients that are all chosen for the specific effects they have on the body. For example, creatine is an energy source for your muscles which boosts performance, while BCAAs protect against protein breakdown to build muscle faster.
Each of our products comes with detailed product information to give you an in-depth understanding of the effects of the ingredients on your body.
The decision on how long to use pre-workout supplements will be down to your exercise schedule, the results you’re seeing and how you feel after taking them. Your tolerance to stimulants builds up with use so if you notice you’re not feeling the full effects of your supplements anymore, a break will help to lower this tolerance again and get you pumped back up when you start using the stimulants again.
Ingredients like creatine are most effective for short, high-intensity workouts so it’s not always necessary to take pre-workout every time you go to the gym. To keep your tolerance down and reduce the number of stimulants you’re using, try switching up your workout schedule so you aren’t using pre-workout every time you set foot in the gym.
Each pre-workout product we stock uses a combination of ingredients specially selected to improve exercise performance and help you build muscle. Each product will have its own combination of these ingredients that you’ll need to choose from based on your own exercise schedule and body goals.
Ingredients like Creatine, Beta-Alanine and taurine are all great energy boosters that fight fatigue and allow you to train for longer, meaning you can build muscle faster. Alternatively, BCAAs aid with muscle repair so your post-workout body can recover quickly and you can hit the gym quicker. Depending on how you train and what you need from your supplements, you’ll need different amounts of these ingredients.
Searching hard for the right product for you might feel time-consuming but getting the right mix will help you get the results you want faster. If you need any further help with this, email us at email@example.com and we’d be more than happy to help.
The ingredients in pre-workout powders won’t directly build muscle, so you might not see the results you’re expecting without also matching it by pushing yourself hard at the gym. What pre-workout will do is bump up your energy, fight off fatigue and help you push yourself further during your workout. Using supplements this way means your harder workouts build muscle faster and pay off quicker.
Pre-workout supplements are filled with a range of ingredients that can benefit users in the gym. Pre-workout is packed with protein which is essential before a workout to ensure your body is synthesising more protein than it’s breaking down. Amino acids, the building blocks of protein are also needed for energy production in the muscles and to build muscles back again after the damage done during exercise.
Other ingredients like L-Citrulline and Citrulline Malate boost nitric oxide which improves blood flow so your muscles get the nutrients they need throughout your workout to recover faster & perform better. Some people also just appreciate the quick energy jolt from caffeine that keeps them going in the gym longer and maintains focus.
Most pre-workout formulas are designed to be safe even if you take them on an empty stomach. Your stomach is typically empty about 2 hours after you’ve last eaten, so using pre-workout powders at this point won’t necessarily negatively affect you but there are some things you should keep in mind.
Having no food in your body to slow the pre-workout down will mean your body absorbs it faster and you might start feeling the effects earlier than you expected. If you don’t want to waste your pre-workout buzz before you’ve even made it to the gym, have something to eat first.
If you suffer from low blood sugar, eating nothing before a workout can also be risky. Low blood sugar can make you nauseous and dizzy and the effects of pre-workout can make these symptoms worse. It’s always best to make sure your body has the fuel it needs before a particularly hard workout and, with every new supplement, consult your doctor if you have any reservations.
Some of the ingredients in pre-workout, such as caffeine can also be an irritation to the body. This isn’t always the case and many won’t experience any irritation when taking pre-workout at any time but there’s an increased risk if you have nothing in your stomach already.
In general, taking pre-workout on an empty stomach isn’t the worst idea but it’s best to eat properly before working out to protect your body and your digestive system at all times.
Specifically with pre-workouts that include caffeine, there are a number of side-effects that some people may experience. Everybody tolerates caffeine differently and it will be the same experience as drinking too much coffee. These side effects can include jitters, anxiety, headaches and digestive irritation. The best way to avoid this is to simply watch your dosage or build up your dosage if you’re a beginner to the product.
Some other side-effects that have been noted with pre-workout include bloating and irritation which can be caused by taking too much creatine, a tingling sensation sometimes caused by Beta-Alanine and diarrhoea which could be a result of using too little water in the mixing of the powder.
These side effects are rare and are often avoidable by dosing correctly but you will need to know your own limits, so take care when using any new mixes.
As with most fitness products, many people have different reactions to each ingredient. This means that, while there aren’t any pre-workout supplements that women can’t have, it’s important to know your own tolerance and dietary needs. For example, the amount of daily protein required is calculated by body weight, so keep an eye on the contents of each product and how they compare with your personal dosage requirements.
