Long Term Effects of Pre Workout: The Good, The Bad & The Ugly




We all want to see results quickly when it comes to working out. But sometimes, we can be our own worst enemy in this quest for gains. 

People often try to speed up results by taking pre-workout supplements, which promise to take your workout to the next level with a boost of energy and performance.

However, like anything, there can be too much of a good thing. These supplements can give you a quick jolt of energy, but they can also have long-term effects on your health if used too often or excessively.

Used in the right way, pre-workout supplements can be a helpful addition to your fitness routine. But it’s important to understand the potential risks before downing your next scoop.

In this article, we’ll explore the long term effects of pre workout supplements and how they can impact your health. We’ll also offer tips on how to use these supplements safely.

Let’s dive in!

What Are Pre-Workout Supplements?

I like to think of pre-workout supplements as the coffee of the fitness world.

Just like coffee can give you a jolt of energy to help you power through your workday, pre-workout supplements are designed to do the same for your workout. These supplements typically contain a mix of ingredients that can include caffeine, amino acids, and other nutrients.

The purpose of these ingredients is to help you achieve peak performance during your workout – improving your alertness, focus, and endurance.

Pre-workout supplements are available in powder or pill form and are typically taken 20-30 minutes before working out. Some people also prefer to take them in the morning as part of their daily routine.

While there’s no one-size-fits-all approach to taking pre-workout supplements, it’s generally recommended that you start with a smaller dose and increase as needed. This will help you gauge how your body reacts to the ingredients and avoid potential side effects.

It’s also important to read the label carefully and follow the recommended dosage. Taking too much of a pre-workout supplement can increase your risk of experiencing side effects.

Now that we’ve covered what pre-workout supplements are and how they’re typically used, let’s take a look at some of the long-term effects they can have on your health.

The Dangers of Pre Workout Supplements

While pre-workout supplements can offer some benefits, there are also some risks. These risks increase when these supplements are used in excess or without guidance from a healthcare professional.

Some potential long term effects of pre workout supplements include:


One of the main ingredients in many pre-workout supplements is caffeine – a diuretic that can cause you to lose more water than you’re taking in.

Dehydration can occur when you lose more fluids than you’re taking in and your body doesn’t have enough water to function properly. Symptoms of dehydration include thirst, fatigue, dizziness, and dark-colored urine [1].

If you’re using pre-workout supplements, it’s important to stay hydrated by drinking plenty of water before, during, and after your workout. You may also want to consider reducing your caffeine intake from other sources, such as coffee or energy drinks.

Gastrointestinal Issues

Pre-workout supplements can also cause gastrointestinal issues like nausea, vomiting, and diarrhea. This is often due to the high amounts of caffeine in these supplements, which can irritate your stomach lining.

To avoid gastrointestinal issues, we’d recommend starting with a smaller dose of your pre-workout supplement and increasing it as needed. You should also drink plenty of water and avoid taking these supplements on an empty stomach.

If you experience gastrointestinal issues after taking a pre-workout supplement, stop using the product and talk to your doctor.

High Blood Pressure

High blood pressure is another potential long-term effect of taking pre-workout supplements due to the caffeine content [2].

Caffeine can cause your blood pressure to rise, which can be dangerous for people with hypertension or other cardiovascular conditions. If you have high blood pressure, you must talk to your doctor before taking any pre-workout supplements.

Irregular Heartbeat

Another potential cardiovascular effect of pre-workout supplements is an irregular heartbeat – often caused by the combination of caffeine and other stimulants in these products.

However, this is only really likely to occur when consuming excessive doses of caffeine (>400mg per day). Consuming moderate amounts per serving should help you avoid such side effects [3].

If you do experience an irregular heartbeat after taking a pre-workout supplement, stop using the product and talk to your doctor. It’s better to be safe than sorry, especially when it comes to your heart health.

Dependence and Withdrawal

Like other stimulants, pre-workout supplements can cause dependence and withdrawal symptoms when used in excess. Symptoms of pre-workout supplement withdrawal include fatigue, headaches, and difficulty concentrating.

If you find that you need to take higher and higher doses of a pre-workout supplement to get the same effect, it’s time to stop using it. And, if you experience withdrawal symptoms when you try to cut back or stop taking these supplements, talk to your doctor.

What to Expect from Your First Time Taking a Pre Workout Supplement

If you’re new to the world of pre-workout supplements, you might wonder what to expect when you take one for the first time. Generally speaking, you can expect to feel more energized and focused during your workout.

You might also notice increased strength and stamina, allowing you to push yourself harder than usual. Of course, every person reacts differently to pre-workout supplements, so starting with a small dose and seeing how your body responds is essential.

Listen to your body and adjust your dosage accordingly. With a little trial and error, you’ll soon find the perfect supplement to help you crush your fitness goals.

Pre-Workouts: What to Look for And What to Avoid

With so many different pre-workout supplements on the market, it can be tough to know which one is right for you. When you’re shopping for a pre-workout, there are a few things you should look for – and avoid.

A good place to start is ensuring the formula only contains ingredients that are backed by science. Steer clear of supplements containing unproven or dangerous ingredients, such as DMAA or Yohimbe.

It’s also important to make sure the supplement is transparent about its ingredient list and dosage. Avoid any products that don’t list their ingredients or dosages in full on the label, as these could be hiding something.

Finally, ensure you’re not allergic to any ingredients in the pre-workout supplement; otherwise, you could experience some unpleasant side effects.

The best pre-workouts contain just a few key ingredients that are backed by science and have been proven to be safe and effective. When in doubt, less is more – so steer clear of any supplements overloaded with ingredients you can’t pronounce or products with excessive doses of stimulants like caffeine.

The Dos and Don’ts of Taking Pre Workouts

Pre-workouts are perhaps the most misunderstood of all the supplements available today. These powerful products can help you push harder and longer in the gym, but they can also lead to unwanted side effects if not used properly.

Here are a few dos and don’ts to keep in mind when taking pre-workouts:

Do start with a small dose: Pre-workout supplements are very potent, so it’s important to start with a small dose to see how your body reacts. Many people find that just half a scoop is enough to get them going.

Don’t take them daily: Pre-workouts are designed for occasional use, not daily consumption. Taking them daily can lead to tolerance issues and make it harder to get results from your workouts.

Do take them with food: Pre-workouts can cause an upset stomach if taken on an empty stomach. To avoid this, consider taking your supplement with a meal or snack.

Don’t forget to hydrate: Pre-workouts contain ingredients that can dehydrate you, so it’s important to drink plenty of water throughout the day – aim for at least eight glasses.

Taking pre-workouts can be a great way to boost your workouts, but using them safely and effectively is essential. By following these simple tips, you can get the most out of your supplements and avoid unwanted side effects.
