Top 5 Caffeine-Free & Non-Stimulant Pre-Workout Supplements For Clean Energy (Without The Crash)

When it comes to getting energized before a workout, a lot of people immediately believe that they need to run to the power pill market to take a supplement with caffeine in it or even take caffeine pills directly.

If you're like me, however, taking caffeine is more debilitating than not taking it.

Everyone has a different level of caffeine tolerance. If you take too much for your body, you might not be able to complete your workout due to the stress put on your system.

Common stimulants used in workout supplements include:

  • Caffeine
  • Green Tea Extract
  • Synephrine

There are people who are allergic to these ingredients or very sensitive to their stimulating nature. Other people simply don’t like how they feel after using a product that has a high volume of caffeine in it. Even women most likely will opt for something which is free from caffeine.

I’ve taken the time to research and compile this guide for the best caffeine free pre-workout supplements so that you can get your workout in without feeling unnaturally wired. Let’s dive in below and get yourself a good peek at one of our pre workout reviews for this particular topic!

In my experience, the number one stimulant to cause people to have the jitters, nausea, the inability to sleep, or simply an unwell feeling is caffeine.

That’s because most people are not used to taking in more than a cup of coffee or two worth of caffeine at a time. However, many supplements like Redcon1 Total War have much more caffeine than this in them and can overload in boosting your system.

It is possible to buy a pre-workout that has a less shocking form of energy. The best caffeine free pre-workout supplements will avoid the irritability, sleeplessness and the occasional rapid heartbeat that can come with ingesting too much caffeine.

The company focuses on proper dosage to achieve this effect with no proprietary blends, and they’re doing an awesome job at it.

Why Should I Consider Caffeine Free & Stimulant Free Formulas?

Before we dive into the “why” behind these alternative products, let’s talk about how the most popular pre-workout drinks work:

Basically, they hit you with a medium-to-high dose of caffeine or other stimulating substances and you can’t help but get at your best pre pump mode to be amped up, crushing it in your next training sesh.

These compounds take only a short time (less than 15-30 minutes in most cases) to seemingly get straight into your bloodstream and get your mental focus and strength at its peak.

Sounds great, right?

While this feeling is admittedly awesome, like all good things it is not without its own set of issues when you find out…

Even the best-intentioned standard pre-workout is guilty of shocking your nervous system with upwards of 400mg of caffeine.

This more than 4 cups of brewed coffee level of caffeine can feel nice in the moment but inevitably leads to the dreaded crash in a few hours...

Caffeine works by inhibiting and suppressing your adenosine receptors and essentially “tricks” your body into not feeling tired even if you should be.

Adenosine is basically your built-in sleep pressure mechanism which gradually increases throughout the day, and once it hits a certain threshold tells your body that it is time to get some shut-eye.

The Unwanted Side Effects of Caffeine

Now that we know how mainstream supps work, it’s important to realize they come with a plethora of disadvantages—especially if taken regularly without cycling usage and taking more than the recommended dosage.

In no particular order, here are the main downsides to this powerful stimulant:


Like most stimulants and addictive substances, when taken regularly your body quickly develops a tolerance. This results in needing to use a higher and higher dosage in order to experience the same effects.

Not only does this mean you will feel less energized over time, tolerances also lead to even the best-intentioned athletes to exceed the recommended dose in pursuit of that perfect pre-exercise feeling.

Messes With Sleep

As mentioned above, caffeine tricks your body into not feeling tired even when you should be. The “tired but wired” sensation is what leads to sleep deprivation from staying up later but also to lower sleep quality and more restlessness when you do finally fall asleep.

Since getting quality deep sleep is essential for recovery and maximizing your gains, this is one of the worst disadvantage of caffeine.

Liver Overload

Caffeine stresses the metabolic functioning of your liver since it is completely detoxified by the liver (as opposed to being split between the kidneys and liver like most substances)

Jitters & Tingling Sensation

You’ve undoubtedly felt this jittery sensation if you’ve had a lot of coffee on an empty stomach. Also, stimulants and compounds like niacin and beta alanine, which belongs to the list of non-essential amino acids, are contributors to the common tingling sensation from pre-workouts, which you can learn more about here.


Another double-edged sword with caffeinated products is their dehydrating effect. Though counter-intuitive, drinking more things like coffee and soda are actually dehydrating you.

Since you are likely training hard and seriously focused in your muscle growth and other solid goals for training while using a pre-workout, you will need to increase your water intake even more in order to maintain a solid hydration level.

Adrenal Fatigue

The stress response caffeine generates in the body taxes your nervous and endocrine system and after prolonged usage leads to adrenal fatigue by shutting down the production of your adrenal glands. These glands produce vital hormones such as cortisol.

Benefits of Taking A Caffeine-Free Pre-Workout

While caffeinated products have their place, you will likely love the benefits of their stimulant free pre workouts counterparts even more.

Here are my favorite reasons to indulge in stim free pre-workouts:

No Crash

What goes up must come down...Hard.

While the exhilarating feeling of great pump boost from caffeine through your veins can help push you to new personal bests, it also leads to an inevitable crash.

Stim-free formulas provide for a smooth surge of energy and leave you feeling ready to take on the rest of the day after a full pump gym session, instead of wanting to take a nap.

Limited Side Effects

Caffeine has just as many side effects as benefits.

Or maybe more.

Just read the section above to see how caffeine affects your body, and to appreciate what you are avoiding by opting for a non-caffeinated product instead.

Cleaner Energy

Manufacturers have to get more creative with stimulant free / caffeine-free pre workout formulas in order to be making a difference in your next training session whether it be in your home gym doing your routines, outdoors or even at your favorite fitness center where you can do more with all the gym equipment surrounding you.

With that creativeness comes new and more effective ingredients that you don’t usually see in typical ingredient lists.

Workout Performance

These well-formulated ingredients are optimized to have a slower energy release over the duration of your workout.

This is in stark contrast to caffeinated products where the crash starts kicking in 30 minutes to an hour into your workout (depending on the dose and your tolerance) which leads to a sub-par performance to round out your routine, when you need to push the hardest.

Greater Pumps

As a vasoconstrictor, caffeine and other stimulants actually work to close up your blood vessels which limits your pump boost, which is exactly what you DON’T want to experience.

On the flip side, natural energy foods like beets are known for opening up your blood vessels resulting in getting you into the mood for a pump mode.

How Should I Take It?

Luckily, you can be more lenient with how you incorporate caffeine-free pre-workouts into your day since they have less drawbacks.

That said, you should still do your best to optimize the timing and dosage for maximum effects.

When Is The Best Time To Take It?

Generally you’ll want to shoot for taking it 15-30 minutes before you start your routine, or as instructed on the packaging.

You can even take it in the afternoons and evenings since there is no caffeine or other stimulants to keep you wired post workout and until bedtime.

Can I Cycle It?

For those of you out there who love the rush of caffeine (you know who you are!), there is still a way to achieve a yin and yang effect with your pre-workouts...

And that comes from cycling.

Cycling allows you to maximize the benefits of caffeine while limiting its detrimental effects.

You can use your caffeine-based supplement for 4-6 weeks, then switch to a non-caffeinated version for the 2-3 weeks.

This way, you cut off your caffeine intake before you develop any serious tolerances, and the first couple weeks you are back on the caffeine bandwagon will feel just like the first time again.

Get Your Exercise Without The Jitters

There you have it. Now that you have hopefully found your pre-workout supplement without caffeine but will give you a boost of energy, you should be able to get through a workout without the stress that a stimulant like caffeine can cause on your body.

Drinking a cup of coffee and taking a supplement full of a large dose of caffeine are two very different things. If your boy can’t take the intense impact that a burst of caffeine can have on your body, don’t force it! There are plenty of options for pre workouts that you can use instead, including the ones that are stimulant free or even caffeine free pre-workouts and a variety of ones without creatine that we have found here.

Don’t force your body to overdo it with caffeine stimulation. You can have a great workout without this sleep-preventing substance.
