Pre-Workout Supplements Guide

What is a Pre-Workout Supplement?

To put things simply, a pre-workout supplement is a product you take shortly before exercising that helps maximize your workout.

These products aim to provide extra energy, power, strength and endurance for a short period after consumption.

Whether you’re lifting at the gym, sparring in the ring, running at the park, or swimming in the pool, pre-workout products will help give you the edge you need to push yourself harder and achieve better results.

Most of the time, pre-workout supplements are in powder form, and must be mixed with water, milk, or another liquid.

You can also find pre-made drinks, bars, and even pills that contain the same active ingredients found in the popular powders.

There are pros and cons to each form of supplement, but in general the more effective pre-workouts come in powder form. Powdered products tend to absorb and digest faster, giving you a quick boost of energy and strength.

Common Ingredients Used in Pre-Workout Products

There are a large number of different types of supplements designed to boost your workout performance.

Some individual supplements, such as creatine, can provide real benefits on their own, while most individual ingredients perform better when blended.

Generally the higher rated pre-workout supplements contain a mix of ingredients to provide optimized results.

Here are some of the more common ingredients used:


Creatine is one of the most widely used supplements available.

An organic acid found naturally in the body, creatine has been the subject of countless academic studies, and when it comes to increasing strength and weightlifting performance, the evidence is clear: creatine works (1)!

Creatine can help increase strength, power and endurance by replenishing your body’s natural supply of ATP, the main energy your body uses for muscle contractions (2).

Creatine is often taken on its own, or as part of a pre-workout shake.

See Our: Best Creatine Supplements


Taurine is an amino acid found naturally in the body.

It is used for a variety of physiological uses, including controlling muscle contractions and maintaining healthy fluid levels within the body.

When you exercise, the body’s natural stores of taurine are depleted. Supplements containing taurine replenish the body’s supply, keeping muscles operating properly.

Also, taurine combined with BCAAs has been shown to decrease post-workout muscle soreness (3).

See Our: Best Taurine Supplements


BCAAs, or branched-chain amino acids, help build muscle, provide energy and reduce muscle tissue breakdown (4).

The 3 BCAAs are leucine, which has been shown to increase strength during workouts, isoleucine, which can help stimulate protein synthesis and aid metabolism during exercise, and valine, which stimulates muscle growth and increases endurance (5, 6).

See Our: Best BCAA Supplements


Beta-alanine is a building block of carnosine. It can help increase physical performance in the 60–240-second range (7).

Carnosine helps to reduce neuromuscular fatigue, leading to increased endurance and increase lean mass (8). Note: beta-alanine can sometimes cause tingling of the skin.

See Our: Best Beta-Alanine Supplements

Citrulline Malate

Citrulline malate is an amino acid which helps to optimize blood flow, increase ATP production, and reduce the effects of fatigue.

Citrulline malate has been shown to help increase strength, aerobic performance, and muscle endurance.

L-arginine is a similarly effective amino acid that is often used in place of citrulline malate (9).

See Our: Best Citrulline Supplements


Tyrosine may potentially help reduce the effects of stress (both mental and physical stress) to increase mental focus and physical endurance (10).

See Our: Best Tyrosine Supplements


Caffeine is an ingredient we all know well.

In supplement form, caffeine anhydrous is the most used type.

Caffeine helps provide energy, while reducing the sensation of effort during exercise (11).

See Our: Best Caffeine Supplements

Stim-Based Pre-Workout vs Stim-Free Pre-Workout

As you know from reading the previous section, pre-workout supplements generally contain a blend of ingredients, ranging from BCAAs to taurine to creatine to caffeine and more.

Although all pre-workouts use a blend of ingredients, there are two distinct categories of these products: stimulant-based, and stimulant-free.

  • Stimulant-based, often just called “stim” preworkouts, include stimulants such as caffeine, yohimbe and others. These tend to be the most popular, and often most effective blends. Stimulants give you energy to exercise harder and longer (caffeine is one of the most effective pre-workout boosters out there), and therefore products that include stimulants can be quite effective.
  • Stimulant-free, often called “stim free” pre-workouts, use a blend of ingredients like creatine, BCAAs, etc. but do NOT include anything considered a stimulant. While these products can be slightly less effective due to the lack of an energy boost, they are still quite popular and useful.

So, what’s better – Stim vs Stim-free pre-workouts?

The answer to that question depends on your specific needs and wants.

If you’re looking for the most intense boost to your workout, absolutely go with a stimulant based product.

If you’re looking to avoid stimulants and caffeine, go with stim-free.

Additionally, think about what time of the day you usually exercise.

Caffeine can interfere with sleep patterns, so if you exercise in the late afternoon or evening, avoid stimulant-based pre-workouts (12).

Benefits of Pre-Workout Supplements

Pre-workouts are commonly used by weightlifters and athletes hoping to improve their workouts.

Keep in mind that pre-workouts always contain a blend of ingredients, so effects may differ from product to product.

These are the primary pre-workout uses that have been studied:

  • Energy: Multiple ingredients included in many pre-workouts can boost energy and stamina. Caffeine, which is found in most pre-workouts may increase adrenaline and other catecholamines, and signal your liver to release sugar into your bloodstream for more energy – all of which can have an effect on energy levels (13). Caffeine has also been shown to reduce the sensation of effort during hard workouts, which adds to the perceived increase in energy levels (14).
  • Strength: Some pre-workouts may actually temporarily boost your strength and endurance. This is largely due to creatine. In a study published in the Journal of Sports Science and Medicine, creatine was found to increase max performance and power by up to 15% (16). Creatine is particularly effective for “short-burst” energy, such as weightlifting, sprinting and racing (17). Other ingredients found in pre workout supplements may also help to improve strength, such as leucine and other BCAAs (18).
  • Endurance: Pre-workouts are designed to help boost your endurance. Branched chain amino acids (BCAAs) are a common ingredient in these products. BCAAs have been shown to reduce concentrations of fatigue substances in the body after prolonged exercise, leading to enhanced endurance and performance (19). This affect is twofold: reducing the fatigue substances such as serotonin helps to reduce muscle damage substances including CK and LDH. Other ingredients, such as beta alanine, can reduce neuromuscular fatigue which may also help to enhance endurance (20, 21).
  • Recovery: While not the primary purpose of a pre-workout supplement, some ingredients can also help to speed recovery time. BCAAs combined with taurine have been shown to reduce symptoms of delayed-onset muscle soreness and muscle damage, and both of these ingredients are commonly found in pre-workout blends (22).
  • Exercise performance: The underlying goal of pre-workout supplements is to enhance athletic performance. This goal is achieved by a number of key ingredients, including citrulline malate (which can enhance athletic anaerobic performance), creatine (which can enhance power by up to 15%), tyrosine (which can help to improve mental focus and endurance), and several other ingredients (23, 24, 25).

Who Can Benefit from Using Pre-Workout?

Just about anyone who has a desire to exercise and stay healthy can benefit from taking pre-workout supplements.

Here are the types of people who will benefit the most:

  • Men – Most men have a desire to be strong and physically fit. While diet and exercise are important ingredients in the path to physical health, proper supplementation can greatly speed up the process. The top ranked pre-workout supplements for men will provide the boost in energy, strength and endurance needed to build muscle and smash through fitness goals. If you’re also looking to lose weight, make sure to check out our list of the top 10 fat burners for men this year.
  • Women – Women can also benefit greatly from taking supplements to boost their workouts. These supplements help to increase fat burning potential and endurance, which can lead to longer, more effective workouts.
  • Bodybuilders – Bodybuilders will perhaps see the greatest benefit from taking a pre-workout. The average bodybuilder already has a lot of muscle and strength, and as you get bigger and stronger, it becomes increasingly more difficult to make gains.

When you reach the higher levels of fitness, you can often hit a wall that’s hard to get past.

It’s called a training plateau, and anyone who has been bodybuilding for any significant amount of time has likely encountered one.

Are There Any Side Effects?

Like any supplement you take, it’s important to know the potential side effects of using pre-workout supplements. Side effects vary depending on the product and the individual taking said product, although generally side effects are mild as long as the product dosage recommendations are followed.

A few common side effects of a pre-workout supplement might include:

  • Tingling of the skin

Many first-time users of pre-workout supplements will be surprised by a tingling sensation felt shortly after consuming the product.

This is a very common side-effect. This tingling, called paresthesia, is caused by large doses of beta-alanine.

It is a harmless side effect, and most people only notice it the first few times they take these supplements (26).

  • Bloating

Some users experience bloating when first using these supplements.

This is largely attributed to creatine monohydrate, a powerful and effective ingredient found in most pre-workout products.

Creatine causes the muscles to draw in extra water, which helps build and repair muscle faster. The bloating is caused by this extra water weight.

This bloating is only temporary, and you will drop the water weight/bloat shortly after stopping creatine supplementation.

For most people, this bloating is not an issue. For some women, the cosmetic downsides of bloating are an annoyance, which is why many products marketed as pre-workouts for women do not contain creatine.

  • Dehydration

Dehydration can be caused by a number of ingredients found commonly in these supplements.

Creatine can cause dehydration because it causes muscles to absorb more moisture, while caffeine and other stimulants can increase dehydration because of their diuretic effects.

To combat the effects of dehydration, make sure you drink enough water.

  • Sleeplessness

Insomnia or sleeplessness can be caused by stimulants like caffeine, commonly found in these supplements.

To combat this, simply allow enough time before consuming the supplement and going to bed (usually 2-3 hours) to allow the effects of caffeine to wear off.

In other words, don’t use a pre-workout supplement for a late-night workout, or you might have trouble falling asleep.

  • Upset stomach

Some people experience stomach upset and/or diarrhea when first starting to take pre-workout supplements.

Everyone reacts differently to the various ingredients used in these products, so it’s hard to narrow down a cause for this side effect.

If you experience stomach upset after beginning a new supplement of any kind, it’s recommended to stop taking that product right away.

In general, side effects are very mild. However, it’s very important to follow the dosing recommendations for these products to avoid potentially more serious side effects. Which leads to our next section…

As always, we recommend you speak with your doctor before taking any supplements featured on this site.

How to Take a Pre-Workout Supplement

Go to: Top 10 Shaker Bottles & Mixers

Since pre-workout supplements are designed to give a short-term boost in energy and athletic performance, they’re best taken shortly before exercising.

Generally, supplements should be consumed 20-45 minutes before exercise, although it varies depending on the product.

Each product will have detailed instructions on how and when to take it. It’s very important that you follow dosing instructions.

Do NOT take more than the recommended dose.

In fact, if you’re new to this type of supplement, you may want to start with a half dose to see how it affects you – especially if you are sensitive to stimulants.

Take a Break Every Few Months

After a month or two of taking a specific product, your body may become adapted to the ingredients used, which can reduce the effectiveness of these supplements.

Because of this effect, many people choose to cycle supplements by using them for 6-8 weeks, then taking a 2-3 week break.

Other people take a product for 6-8 weeks, then switch to another product for 6-8 weeks, and repeat.

Pre-Workout Supplements are almost always in powder form, which means you will need to mix it with water in a shaker bottle.

For the ultimate convenience, we recommend you use a BlenderBottle. They’re inexpensive and get the job done!

Read the Label!

Before taking any supplements, make sure you read the instructions that the manufacturer has placed on the label. This is a very important step.

What to Look For in a Good Pre-Workout Product

There are many factors that go into choosing a solid pre-workout for you. Here are some things to look for:

  • Application to your goals – Ask yourself, does the product apply to your goals? If you’re looking to lift heavy and get shredded, you’ll want to find the a pre-workout for pump. If you’re looking to lose weight and get more toned, you should look for a pre-workout product for cutting.
  • Quality of ingredients – Take a close look at the ingredient list of any product you are considering. Look at the type of ingredients they use, and the quality/sources of those ingredients.
  • Brand recognition – Have you heard of the brand? Are they well respected in the industry? Generally, sticking to the well-known, reputable brands will lead you to the best products.
  • Value for money – How much does the product cost per serving? How does that compare to the other products you’re considering? Be sure to compare on a per-serving basis instead of just looking at the package price of different products.
  • Taste/mixability – You’ll want to find a good-tasting product that mixes well, so you’ll actually want to take it on a regular basis!
