How Strong is Pre Workout?

A new study looks at the effects of pre-workout supplements on exercise performance.


Pre-workout supplements are popular among athletes and bodybuilders looking to boost their performance in the gym. The ingredients in a pre-workout supplement can vary, but generally contain stimulants, like caffeine, that act as energy boosters. Pre-workout supplements also typically contain other key ingredients like BCAAs, beta-alanine, and creatine, which can improve energy, strength, and endurance during a workout. We’ll discuss the various ingredients in pre-workout supplements and the benefits they provide.

What is Pre Workout?

Pre workout supplements are nutritional drinks or powders that are taken prior to training. These products can contain ingredients such as amino acids, caffeine and other compounds which can help enhance performance. Pre workout supplements can be used to boost energy, improve focus and help give the user an edge when it comes to athletic performance.

It is important to note however that not all pre workout supplements are created equally and it is important to do your research when considering purchasing one. Generally these products contain a range of vitamins and minerals, along with stimulatory agents such as caffeine. As a result, it is important to look at the list of ingredients before buying to ensure that these substances are safe for you to consume.

In terms of the strength of the product this depends on the individual formulation and what ingredients have been used in order for it to achieve its desired effect. Caffeine content is one indicator or measure of strength; higher doses will generally produce stronger effects compared with lower doses. Other ingredients such as amino acids may have their own unique effects on performance as well so looking into individual results should provide insight into overall effectiveness.

Benefits of Pre Workout

Pre-workout supplements offer a wide range of benefits that can help enhance physical performance and reduce fatigue during exercise. Compared to the consumption of energy drinks, pre-workout products provide a more focused and sustained energy boost without the added sugar calories. They may also contain other ingredients such as nitric oxide boosters, which help to further support muscle growth and improve circulation around the body.

For those who want to maximize their workout results, pre-workout supplements can be an effective way to get an edge in the gym or on race day. Pre-workouts are designed to provide athletes with extra energy for improved focus and performance during activities requiring intense physical output. In addition, some pre-workouts may contain added beneficial ingredients such as amino acids and extra vitamins that can help improve recovery time after exercise.

Furthermore, certain pre-workout products contain ingredients proven to reduce inflammation and decrease excessive acid build-up in muscles, allowing users to increase gains while decreasing fatigue after intense workouts or competitions. When taken correctly and as part of a well balanced diet, pre workout supplements can play an integral role in optimizing physical performance for both professional athletes and casual gym goers alike.


Pre-workout supplements are great for giving you that extra energy boost before a workout. Most pre-workouts will include a blend of ingredients like caffeine, creatine, and L-Citrulline, which all help to increase energy, focus, and endurance. It’s important to know what is in your pre-workout to make sure it is safe and effective. Let’s take a look at the different ingredients found in pre-workouts.


Caffeine is one of the most popular ingredients used in pre-workout supplements. It can produce not only an alert and active feeling but an increase in of focus, energy, and performance ability. Caffeine can also increase endurance levels during physical activity. Pre-workout supplement caffeine content can range depending on the product desired effects and individual serving size, but generally ranges from 100-350mg per serving. A cup of home brewed coffee contains approximately 95 mg of caffeine, so a pre-workout with 200 mg would be equivalent to about 2 cups of coffee. Caution should be taken for those sensitive to stimulants or have a medical condition influenced by caffeine intake, as some products have higher concentrations that could cause adverse reactions.


Beta-Alanine is an amino acid that acts as a buffer, delaying the onset of fatigue. When taken during exercise, it helps to support muscular endurance, allowing you to stay in your workout longer. It is also often used to help reduce muscle soreness after physical activity.

Beta-Alanine converts in the body to form Carnosine which prevents acid from building up in our muscles during physical activity – allowing us to perform at higher intensity for longer periods of time. Plenty of research supports this ingredient as an addition to pre-workout supplements for increased performance and endurance.

It’s important that you look for a product with a minimum of 3g per serving in order to get the optimal benefits from Beta-Alanine supplementation. Keep in mind; the recommended dose is around 4 grams daily split over two doses about two hours apart for best results and maximum effectiveness.


Creatine is one of the most popular ingredients found in pre-workout supplements. It is an amino acid compound found naturally in the body that helps to supply energy to cells, especially muscle cells. Creatine is thought to help improve muscle endurance, strength and recovery during high intensity exercise, as well as aid in muscle growth and development by helping create a cellular environment that is more conducive to muscle building. Pre-workout supplements often contain creatine either alone or as part of a proprietary blend of performance enhancing ingredients. Different forms of creatine are available including creatine monohydrate (the recommended form) and other longer chain derivatives such as Kre-Alkalyn and Magnesium Creatine Chelate.

Citrulline Malate

Citrulline Malate is an amino acid commonly used in pre-workout supplements. It is a combination of the amino acids citrulline and malate, and is thought to have a range of potential benefits when taken before exercise.

Citrulline Malate increases levels of nitric oxide in the body, which helps dilate blood vessels and can improve oxygen supply to muscles during exercise. This may help increase the amount of work that can be done in one set and may potentially reduce muscle fatigue.

In addition, Citrulline Malate is thought to increase energy production, improve muscle function after exercise, delay muscle soreness and reduce post-exercise fatigue. It can also act as an antioxidant, removing excess free radicals from the body that are produced during strenuous physical activity.

Overall, Citrulline Malate has been shown to benefit both aerobic and anaerobic exercise performance due to its ability to increase oxygen delivery and energy production for improved physical performance outcomes.

Side Effects

Pre-workout supplements can help you increase your energy and focus at the gym. However,like most supplements, they do come with potential side effects. Be aware that these supplements can contain high levels of stimulants, and they can even have short-term and long-term health risks. In this section, we’ll take a look at the potential side effects of pre-workout supplements.


feel uncomfortable when taking pre-workout supplements, particularly those high in caffeine and other stimulants such as taurine. A common complaint is feeling jittery after working out. This can be caused by overstimulation of the central nervous system, leading to feelings of restlessness, irritability and an increased heart rate. The intensity of the symptoms can range from mild to severe and can last several hours after working out. To help reduce jitters, gradually increase your dose over time to become accustomed to the effects or reduce your dosage if necessary. Furthermore, it’s advised that you avoid drinking energy drinks or other caffeinated beverages near your workout session to help reduce the risk of adverse effects caused by this type of pre-workout supplement.


Nausea is a common side effect of taking pre-workout. It is usually caused when too much caffeine is in a single serving. The amount of caffeine in different pre-workouts can vary based on the product. Depending on your body type and sensitivity to caffeine, you may experience nausea if you exceed the recommended dosage or are new to taking a pre-workout supplement.

To prevent nausea, make sure you read the label on any pre-workout product and start out with a lower than recommended dose before increasing it once your body has had time to adjust. You can also try taking your pre-workout with food or spreading the recommended dosage out into smaller doses throughout the day instead of all at once to help manage its effects better. Additionally, adding electrolytes or anti-nausea medications may also provide some relief from feeling nauseous after taking a pre-workout supplement.


Pre-workout supplements contain ingredients that can cause dehydration. Caffeine, found in many pre-workout formulations, is known to cause diuresis--an increase in the secretion of urine. As a result, individuals taking pre-workout supplements may experience polyuria--the passing of large amounts of urine than usual. Studies suggest that caffeine is the most influential factor in dehydration related to pre-workout supplementation. Additionally, some formulations also contain diuretic substances such as uva ursi and junifferua which can further aggravate dehydration risk.

The potential for dehydration increases with exercise as well since as sweating is typically increased when individuals engage in rigorous physical activities. Thus, it is advised to drink water before, during and after consumption if you are engaging in physical activities afterwards; this will help counteract the effects of the possible diuretic action of the substance. It is also recommended that those taking pre-workouts be aware of any signs or symptoms associated with dehydration and electrolyte imbalance such as muscle cramps or lightheadedness and adjust their intake accordingly and consult a physician if necessary.


When it comes to dosing pre-workout, it is important to find the right amount for your body. Pre-workouts often come in a variety of flavours and concentrations, so it is important to find the right one for your needs. Dosing for pre-workout can range from one scoop for those just beginning to three or four scoops for those more experienced. This section will explore the recommended dosing for pre-workout supplements.

When purchasing and consuming pre-workout supplements, it is important to consider the recommended dose. Depending on the type of supplement, dosage may vary based on the label instructions or individual needs. In general, pre-workout supplements are designed to be used before physical activity and should not be taken on a regular basis in order to avoid potential side effects from overuse.

Most pre-workouts will include a blend of ingredients consisting of vitamins and minerals as well as stimulants like caffeine and other legal performance-enhancing ingredients that can help provide an energy boost for your workouts. It is important to pay attention to the recommended dose since too much can cause harm when taken in excessive quantities. The suggested serving size is generally printed on the back of all labels, so it’s important to check carefully before you buy.

In general, most pre-workouts should have between 2 and 4 scoops per serving for an adult following these steps: Begin with 1 scoop initially or two scoops for experienced athletes; gradually increase servings up to two scoops after several weeks without any adverse side effects; ultimately consume between 2–4 scoops per workout depending upon your response. If necessary, break down increments of appropriate amounts depending upon body weight (e.g., 150 lbs = 1/2–3/4 scoop). Additionally, avoiding drinking large amounts of water directly before or after taking a supplement is advised so that digestion does not become impaired in any way. Following these guidelines and doing some research about different types of supplements can help you find a safe regimen that works for your individual needs.

Timing of Pre Workout

When it comes to timing a pre-workout, the most important thing is to pay attention to how your body responds. Everyone has different needs and can tolerate different amounts of stimulants and supplements, so it’s important to experiment with the timing to maximize their effects within the confines of safety.

A general rule of thumb is to take pre-workout about 30 minutes prior exercise for optimal results. This allows for enough time for the body to absorb the ingredients and put them into circulation before you need them. Pre-workouts often contain stimulants such as caffeine which will take effect once they hit your bloodstream, so timing them properly can ensure that you’re ready when it’s time to hit the gym or head out on a run.

It’s also important not to consume too much pre-worout supplement at once as this may cause adverse reactions such as headaches, nausea or heart palpitations. To avoid these potential problems, stick with recommended doses — never exceed what’s listed on the product’s label unless otherwise advised by your doctor or healthcare provider. Additionally, consider spreading out multiple doses throughout the day if necessary so that all of the supplement can be absorbed while still allowing your body adequate time between servings in order to escape any potential side effects from consuming too much in one sitting.

How Long Does Pre Workout Last?

The duration of action of pre-workout supplements varies depending on the ingredients included. Caffeine is one of the main ingredients in many pre-workouts and typically provides the most immediate effect. Caffeine can remain in the system for up to six hours, although the most intense effects are usually felt within 60 minutes of ingestion.

Other stimulants such as yohimbine, guarana and bitter orange extract may provide additional boosts but they also complete their action within similar timeframes to caffeine. Beta-alanine is an amino acid included in some pre-workouts that is absorbed by the muscles to help produce higher energy levels during exercise. After two weeks of regular consumption Beta-alanine should reach maximum levels in your system and provide a sustained energy boost for up to sixty minutes after ingestion.

Nitric oxide ingredients such as L-arginine, citrulline malate and L-citrulline can last for several hours after dosing and provide sustained increases in blood flow for improved nutrient delivery throughout your workout session. Creatines like creatine monohydrate metabolize quickly but also have long reaching effects as they accumulate over time to produce optimal results from exercise routines over a longer period.

Ultimately pre-workout supplements will offer different benefits depending on their ingredient profile, but most will have effects that last at least one hour following use with some lasting up to six or more hours after ingestion. As always it’s important to consult your physician before starting any supplement regimen and ensure that your chosen product agrees with your individual health needs.


In conclusion, pre-workout supplements come in numerous unique flavors and offer individuals different levels of anticipated benefits. Research suggests that some ingredients, such as caffeine and creatine, can be beneficial for athletes and those who want to maximize their efforts in the gym. However, it is important for individuals to remember that everyone’s body chemistry is different. Therefore it is best to experiment with different pre-workout products before committing to one. Additionally, it is important to remember that even if taken correctly, pre-workouts may have side effects caused by the ingredients used in the formula. When considering taking a pre-workout supplement of any kind make sure you read labels carefully and talk to your doctor before beginning its use.
