If you're serious about your workouts, you've probably run into pre-workout supplements.

They're designed to help you get the most out of your workout by boosting your energy, endurance, and focus.

But what exactly are they, and why should you consider using them?

Let's dive in.

Why Use Pre-Workouts: Quick Answer

Pre-workout supplements are used to enhance physical performance, increase energy, and improve focus during a workout.

They contain a blend of ingredients like caffeine, creatine, and amino acids that work together to maximize your training session.

Understanding Pre-Workout Supplements

Pre-workout supplements are a bit like a turbo boost for your workout. They're designed to help you push harder, lift heavier, and train longer. But how do they do this? It's all about the ingredients.

The Role of Key Ingredients in Pre-Workout Supplements

Let's examine some of the key ingredients commonly found in pre-workout supplements and their benefits.


Caffeine is a well-known stimulant that can enhance alertness and ward off feelings of fatigue. It's also been shown to improve exercise performance, increase power output, and boost fat burning. However, it's important to note that individual tolerance to caffeine can vary, and high doses can lead to side effects like jitters, anxiety, and sleep disturbances.


This is one of the most well-researched supplements in sports nutrition. Creatine supplementation has been shown to improve strength, power output, and high-intensity exercise performance. It works by helping your muscles produce more energy during heavy lifting or high-intensity exercise.


This amino acid is known for the 'tingling' sensation it can cause in the skin. More importantly, beta-alanine can help buffer acid in your muscles, reducing fatigue during high-intensity exercise.


Citrulline is an amino acid that improves blood flow to body tissues. This can be especially beneficial during high-intensity exercise, as better blood flow allows for more oxygen and nutrients to be delivered to working muscles. The average amount of citrulline in pre-workout supplements is around 4.0 grams, as per the same study.

Beetroot Extract:

Beetroot extract is a rich source of nitrates, which your body can convert into nitric oxide. Nitric oxide helps increase blood flow to your muscles, enhancing their function during workouts. While beet juice is a natural source of nitrates, beetroot extract provides a more concentrated dose, making it a common ingredient in pre-workout supplements.


Taurine is an amino acid that plays a key role in muscle function. It's included in pre-workout supplements due to its potential to improve athletic performance. The average amount of taurine in pre-workout supplements is around 1.3 grams, according to the Nutrients study.


Tyrosine is an amino acid that can help improve alertness, attention, and focus, which can be beneficial during intense workouts. The average amount of tyrosine in pre-workout supplements is around 348.0 mg, as per the same study.

Why Use Pre-Workout Supplements?

Pre-workout supplements are designed to help you get the most out of your workout. They can enhance physical performance, increase strength, improve endurance, and boost concentration and focus. Here's why you might consider using them:

1. Enhanced Physical Performance

As we've discussed, ingredients like creatine and beta-alanine can enhance your physical performance during workouts. Creatine boosts your muscles' energy production, while beta-alanine helps delay muscle fatigue1.

2. Improved Concentration and Focus

Many pre-workout supplements contain ingredients like caffeine and L-theanine, which can improve your concentration and focus during workouts2.

3. Increased Strength and Endurance

By enhancing your physical performance and delaying muscle fatigue, pre-workout supplements can help you lift heavier weights and workout for longer periods, leading to increased strength and endurance3.

4. Better Mood and Motivation

Some ingredients in pre-workout supplements can improve your mood and motivation, making you more likely to stick to your workout routine3.

5. Faster Recovery

Some pre-workout supplements contain ingredients that can help speed up recovery after workouts, reducing muscle soreness and helping you get back to the gym sooner3.

Reasons to Use Pre-Workouts

Pre-workouts are popular among fitness enthusiasts for a variety of reasons:

  1. Improved Performance: Pre-workouts are designed to enhance your performance during workouts. They contain ingredients that can increase your energy levels, improve your focus, and help you train harder and longer. A study published in the Journal of the International Society of Sports Nutrition reported that combining pre-workout with HIIT workouts resulted in significant increases in VO2 max, training volume, and lean body mass.

  2. Increased Concentration and Focus: Pre-workouts are packed with caffeine, which is known to enhance cognition. This can help you stay focused during your workout and get the most out of each session.

  3. Enhanced Endurance: Some pre-workouts contain ingredients like BCAAs (Branch Chain Amino Acids) and creatine, which have been found to improve endurance during a workout and increase strength.

Reasons Not to Use Pre-Workouts

Despite their benefits, pre-workouts may not be for everyone. Here are some reasons you might want to avoid them:

  1. Potential Side Effects: Pre-workouts can cause side effects like jitters, itching, and interrupted sleep. These are harmless but can be uncomfortable.

  2. Tolerance Build-Up: If you take pre-workouts regularly, your body can build up a tolerance to its effects. This means you might need to take more of the supplement to get the same effects, which can lead to overuse and potential health risks.

  3. Digestion Problems: Some ingredients in pre-workouts, like sodium bicarbonate, magnesium, creatine, and caffeine, can cause digestion issues. (Read: Should You Take Pre-Workout on An Empty Stomach?)

Types of Pre-Workouts

Pre-workouts come in different types, each designed to meet specific needs:

  1. Stimulant Pre-Workouts: These are the most common type of pre-workouts. They typically contain caffeine and other stimulants to boost energy levels.

  2. Non-Stimulant Pre-Workouts: These pre-workouts do not contain stimulants. They are a good option for people who are sensitive to caffeine or who work out late in the day.

  3. Pump Products: These pre-workouts are designed to increase blood flow to the muscles during workouts, leading to better "pumps". They often contain ingredients like arginine and citrulline.

Safety and Side Effects of Pre-Workouts

While pre-workouts can be beneficial, it's important to use them safely. Overuse can lead to health issues like anxiety, insomnia, and high blood pressure. Always start with a half dose to see how your body reacts, and avoid pre-workouts that contain excessively high levels of caffeine.

Can I use a pre-workout supplement every day? While it's generally safe to use pre-workout supplements on the days you exercise, using them every day can lead to tolerance, which means you may need to take more to get the same effect. It's a good idea to cycle off these supplements every few weeks.
