Should You Drink Pre Workout on an Empty stomach?

Many people ask whether they should drink pre workout on an empty stomach or not. The answer isn’t always clear, but there are a few things to consider.


Pre-workout supplements can be an effective way to help increase energy levels and improve performance during exercise. These supplements usually contain caffeine and other performance-enhancing ingredients such as B vitamins, creatine, taurine, and amino acids. While these ingredients are often beneficial when taken before a workout session, their effects may differ depending on whether they are consumed with or without food. In this article, we will discuss the potential benefits and drawbacks of drinking pre-workout supplements on an empty stomach.

Benefits of Drinking Pre-Workout

Pre-workout drinks can provide an extra kick of energy before a workout and help you get through a tough session. They can also aid in muscle recovery, help reduce fatigue, and increase your muscle endurance. It’s important to understand the advantages and disadvantages of drinking pre-workout when considering what’s best for your body. Let’s take a closer look at the possible benefits of pre-workout supplementation.

Improved Energy

One of the main benefits of drinking pre-workout is improved energy. Many pre-workout drinks contain caffeine, which can help to increase alertness and reduce fatigue during exercise. Drinking pre-workout on an empty stomach may further improve the levels of energy you experience, allowing you to work out for longer or to push yourself harder. Caffeine also helps to increase fatty acid mobilization and lipolysis, which can lead to increased fat burning and weight loss. Other common ingredients in pre-workout drinks are vitamins B6, B12 and niacin as well as important electrolytes such as sodium, potassium and magnesium. These nutrients are known for their energy boosting properties and have been proven to help improve overall performance.

Improved Focus

Drinking pre-workout before exercise can help to improve focus, alertness and mental clarity. During exercise, your brain naturally reduces the amount of energy it spends on tasks, leaving you feeling fatigued or overwhelmed. Caffeine helps to reduce this feeling and can give you a much needed mental boost prior to a demanding workout. Additionally, caffeine may help you increase the intensity of your workout, resulting in improved physical performance. Increased focus and intensity may help you reach your fitness goals faster and higher than ever before!

Improved Performance

Drinking a pre-workout supplement before exercise may help to enhance performance during the workout itself. Pre-workout supplements typically contain stimulates such as caffeine, and other compounds like B Vitamins and amino acids that have been linked to improved strength and endurance. Research has shown that pre-workout supplements can improve aerobic exercise performance, as well as provide additional energy to increase exertion levels. This increased level of stimulation can also promote fat burning and improved mental focus while exercising.

Risks of Drinking Pre-Workout

Drinking pre-workout can give you an energy boost and help you push through those tough workouts. However, pre-workout can also have some risks if not used properly. It is important to know the potential risks of drinking pre-workout on an empty stomach so that you can make an informed decision. In this article, we will go over the potential risks of pre-workout consumption on an empty stomach.

Gastrointestinal Issues

One of the most common risks associated with drinking pre-workout on an empty stomach is gastrointestinal issues. The caffeine, sugar and other stimulants present in pre-workout drinks can cause upset stomachs when consumed too quickly or when taken on a completely empty stomach. When consumed without food to slow down digestion, these ingredients can irritate the gut and cause nausea, cramping, diarrhea and/or vomiting. Additionally, the harsh ingredients present in some pre-workout formulations can damage the delicate lining of the stomach and irritate sensitive tissue throughout your digestive tract.

Aside from irritability and discomfort during intense workouts, drinking too much pre-workout without taking protective measures such as eating small meals or having larger meals several hours before can also lead to more serious long-term consequences including metabolic disorders like diabetes or hypoglycemia. Therefore it is important to ensure that you are consuming a balanced meal prior to engaging in strenuous exercise if you are relying heavily on large doses of caffeinated pre-workout beverage for energy boosts.


Dehydration is a common occurrence when drinking pre-workout on an empty stomach. Pre-workout drinks are often composed of ingredients that cause sweating and the effects of dehydration can be compounded in the absence of food. Symptoms of dehydration can include fatigue, dizziness, headache, dry mouth, decreased urine output and confusion. It’s important to stay hydrated during exercise, but more so when drinking pre-workout on an empty stomach. It’s important to drink water before, during and after your workout as well as taking regular breaks for hydration. Collapsing from dehydration is a real risk and therefore it is advisable to drink pre-workouts with a meal instead of on an empty stomach.

High Blood Pressure

Consuming pre-workout on an empty stomach may increase your risk of developing high blood pressure. Many pre-workouts contain stimulants such as caffeine or guarana, which are known to raise heart rate and constrict blood vessels. This can lead to short-term increases in heart rate and blood pressure, and even chronic issues. If you choose to consume these beverages, it’s important to monitor your heart rate throughout the day and note any changes that correspond with drinking these beverages. It’s also a good idea to check with your doctor before attempting any kind of strenuous physical activity involving stimulants if you have any existing conditions relating to high blood pressure or a fast heartbeat.

What to Consider Before Drinking Pre-Workout

Pre-workout drinks contain stimulants, carbohydrates, and electrolytes which can improve your performance and give you an extra boost of energy before your workout. However, it’s important to consider all the potential consequences of drinking pre-workout on an empty stomach before doing so. This section will cover all the factors you should consider before deciding to drink a pre-workout.

Time of Day

When considering if you should drink pre-workout on an empty stomach, the time of day is an important factor. Many people train first thing in the morning and may not have had a chance to eat yet. In this case, it is best to still wait to consume pre-workout until after some food has been eaten. Waiting 1–2 hours can help provide a sense of fullness and provide your muscles with fuel for the upcoming workout.

If training later in the day and you’ve already eaten, avoid eating too close to your workout session (1–2 hours before) as your body will still be digesting through the meal when exercising. Instead, drinking a pre-workout can be beneficial as it will boost energy levels and help sustain optimal performance for your training session. If you don’t have time to eat one or two hours prior to exercise, consider including carbohydrate sources that are easy to digest such as fruit juices or smoothies with added protein sources before your workout.

Type of Pre-Workout

There are a variety of pre-workout supplements available and they all contain different ingredients with different effects. For example, some contain primarily stimulants, while others are designed to boost your energy level without the jitters associated with caffeine-based products. It is important to read labels carefully and know the ingredients before taking any type of pre-workout supplement.

Some common ingredients in pre-workout supplements are creatine, caffeine, beta-alanine, and B Vitamins. Creatine provides energy during short bursts of activity such as weightlifting or sprinting. Caffeine boosts energy levels and alertness for longer periods of time and can also help burn more fat during exercise. Beta-alanine helps maintain optimal muscular performance during high intensity activities like running or swimming laps. Lastly, B Vitamins increase cellular energy production, which can help enhance exercising results.

It is important to note that not all pre-workout supplements are created equal; some are formulated specifically for athletes while others target everyday exercisers. Additionally, if you take any regular medications or have existing health conditions consult with your physician before taking any type of supplement as certain ingredients may interact negatively with existing medications or cause other side effects.


When exercising, it’s important to consider your nutrition carefully. Eating a balanced diet with complex carbohydrates, protein and healthy fats can provide the energy and nutrients needed for a safe and successful workout. If you choose to drink pre-workout drinks before exercising on an empty stomach, there are several important factors to consider.

Nutrition: Pre-workout drinks often contain undesirable ingredients like sugar, artificial sweeteners and sodium which can harm your overall health if consumed in large amounts. Be sure to check the nutrition label for any potential allergens and information about added sugars or caffeine that could affect your performance. Additionally, many pre-workouts contain B vitamins which may help boost energy levels but could also result in feelings of jitteriness or restlessness in some individuals.

Dehydration: Pre-workout drinks are typically full of electrolytes that can help replenish electrolyte levels during exercise and reduce dehydration risks associated with strenuous activity. However, they may also contain added sugars which could upset delicate fluid balance in the body if consumed on an empty stomach or without enough water. Therefore, it is important to stay hydrated while drinking pre-workout beverages by drinking water throughout the day as well as after each workout session.


In summary, drinking a pre-workout drink on an empty stomach can have some effectiveness depending on the type and individual’s goal. Generally, pre-workout drinks with caffeine or stimulants should not be consumed on an empty stomach. If someone is trying to build muscle, it is best to consume a pre-workout with carbohydrates and protein before working out. Consuming a pre-workout can also provide energy and improve focus and alertness during physical activity. Ultimately, it is up to the individual to decide what type of pre-workout beverage will be most beneficial for them based on their goals.
