Is Pre-Workout Addictive? (What It Is and How It Can Happen)

Are you hooked on pre-workout supplements? Pre-workouts have been proven to boost workout performance, and there's a huge upside to taking them.

However, there are a lot of rumors going around about the dark side of pre-workout, specifically around addiction.

You don’t want to become reliant on pre-workout, and in this guide, we'll explain what the risks are, how you can mitigate them, and provide a clear answer to the question "is pre-workout addictive?"

Yes, it is possible to get addicted to pre-workouts, but it’s not actually the pre-workout supplement you’ll become addicted to.

Pre-workout supplements are designed to improve the effectiveness of your training sessions and boost workout productivity.

They’re really popular in the fitness industry, but there’s a surprising lack of understanding about what goes into them.

Pre-workout ingredients vary depending on what brand you use.

Still, most good pre-workout supplements contain energy in the form of a stimulant, fuel for your muscles in the form of amino acids like L citrulline and beta-alanine, and dietary nitrates.

These enhance nitric oxide production to increase blood flow and also usually contain some forms of vitamin B.

Given that pre-workout is designed to give you better performance in the gym and improve your health, it's natural to assume they are safe.

The majority of the ingredients are fine, but the high volumes of stimulants are what can cause addiction.

Most pre-workout supplements contain caffeine or other stimulants to boost energy levels and enhance focus while you train.

The caffeine levels in some pre-workouts are very high, and some contain more than 400mg in a single scoop. That’s about as much caffeine as 4 cups of coffee!

Caffeine is broken down by your body and used for extra energy, but your body's tolerance can increase over time.

When your tolerance increases, your dependency also increases because your body expects to have it in your system at all times. This is when addiction happens.

Therefore, you can become addicted to pre-workout supplements if your caffeine tolerance changes.

How Caffeine Impacts Your Body (The Downsides Explained)

What Does Caffeine Do To Your Body?

It is possible to become addicted to caffeinated pre-workout, but what exactly does it do to your body?

Well, it's a powerful stimulant that increases activity in your brain and central nervous system. This makes you more alert and focused so that you can train harder.

The impact of caffeine on your nervous system causes you to produce cortisol and adrenaline.

These hormones are released as part of your fight or flight response and increase your energy levels to deal with potential threats.

By taking a supplement with a stimulant, you can use this to your advantage and get more from your workout.

Caffeine also impacts your adenosine receptors. These receptors help to control your neural activity and cause your body to sleep when you need rest.

Caffeine blocks these adenosine receptors, which triggers a short burst of alertness, effectively blocking the hormones which make you tired.

Once the stimulant wears off, more adenosine receptors will grow again, but it can leave your brain struggling. [1]

If you take a small amount of caffeine, you can feel refreshed, focused, and ready to push your training limit higher.

The issues come when you have too much, and this is why some pre-workouts can be dangerous.

What Is The Dark Side Of Caffeine?

Caffeine has some benefits, so it's easy to see why it's included within a pre-workout supplement.

However, taking too much can put your body under stress, leading to increased epinephrine levels.

Epinephrine is a chemical compound that is designed to boost your metabolism, but studies suggest there are some nasty side effects if too much is produced. [2]

The impact caffeine has on the growth cycle of adenosine receptors is manageable while you’re taking it, but once you stop, you'll feel all the adverse effects.

This includes headaches, irritability, and mood swings because you have increased functional sensitivity to adenosine. You can also feel completely exhausted as you suffer from caffeine withdrawal.

The long-term negative caffeine effects can impact your central nervous system and change your behaviors.

For example, you can become anxious, and it may impact your mental health, as well as cause long-term fatigue.

How Do You Develop Caffeine Addiction?

Caffeine addiction is the real dark side of caffeine, though it’s usually described as tolerance or dependence.

It happens when you consume high amounts of caffeine daily for a long period of time. This impacts your brain chemistry and can even impact your body composition.

Caffeine dependence only happens when you take a lot, and I mean a serious caffeine overload. You’d need to consume over 750mg a day, which is the equivalent of 3-4 scoops of pre-workout products.

Sticking to the recommended dose of pre-workouts is easy, but the real danger is from other caffeinated supplements.

Energy drinks, black coffee, and other caffeinated beverages can all contain up to 200mg of caffeine. When you add this on top of other supplements, it's much easier to get to 750mg daily than you think.

If you take too much caffeine (whether through pre-workouts or coffee), then your brain becomes less sensitive to adenosine receptors.

This leads your body to produce more and means when you have no caffeine in your system, you're naturally very tired.

This can lead to a yo-yo effect with your energy levels going massively up and down and can leave you addicted.

Possible Long Term Dangers Of Pre-Workout Addiction

Addiction to pre-workout and the caffeine addiction that comes with it can have some dangerous long-term impacts:

Increased Heart Rate

Caffeine stimulates your blood vessels and causes your heart rate to increase.

This can provide you with a short-term boost, but the increased blood flow can have a negative impact on your blood pressure.

This can increase your risk of heart disease, strokes, and heart attacks.

Weight Loss

Summary pre-workout supplements with high levels of caffeine can actually cause unhealthy weight reduction.

The caffeine will increase your internal body temperature, which in turn helps to burn fat.

In small doses, this can help you lose weight even after your training session is over, but if you're taking too much caffeine, it can mean an uncontrolled reduction in size.

Not only will this cause you to lose muscle, but it can also leave you feeling weak and tired.

Even small changes in your routine can become difficult, and this can lead to a wide range of mental health issues.

How To Best Manage Your Pre-Workout Dependence

If you find yourself becoming dependent on pre-workouts, then you need to take action. Here are some tips to help you manage it:

Reduce Your Intake

As with any addiction, it’s really difficult to go cold turkey and stop overnight. Even if you could, the caffeine withdrawal symptoms could be too much and make you really sick.

The most important thing to do is to try and get yourself down to the supplement companies' recommended dosage of your pre. This should start to limit the stimulatory effects and gradually reduce your dependence.

Even if you don't feel ready to completely stop taking pre-workout, you should look into blends that contain cognitive enhancers.

These help balance the effects of caffeine and can give you back some of your mental edge while you recover.

It’s important to realize that you’ll still need the caffeine for energy production while your body recovers, but you should be able to gradually reduce your dose until you are no longer dependent.

Switch Your Caffeine Supply

Caffeine is the ingredient that is keeping you dependent on pre-workouts, but it’s not the only way to improve your mental clarity and manage your dependence.

Switching to a daily coffee or green tea can give you the same kick of caffeine, but without the other ingredients. This should help you gradually reduce your dependence on supplements over time.

Just be sure to avoid introducing any banned substances into your diet because these can be a lot worse for you than pre-workouts.

Get Help

If you just can’t stop taking the supplements, it's time to get some outside help.

Addiction centers and counseling can help you to remove your reliance on pre-workouts and caffeine, and while there could be a long recovery time for your body, professional help should help you get back to normal. [3]
