Caffeine Free Pre Workout Ranking Criteria

Different criteria can help you determine whether or not a caffeine free pre workout is worth it. Of course, you don't want to buy a product that doesn't meet your expectations.

Continue reading as we're about to show you exactly what you should pay attention to when getting your hands on a caffeine free pre workout.


First, we have the ingredients, which we consider to be the most critical aspect of the entire caffeine free pre workout.  

They're so important because if your product has the right ingredients, you'll notice massive changes in your workout performance - better pumps, focus, and power.

If the product doesn't use the right ingredients, it will not do much for you or your workout performance. Always check the product's ingredient label to ensure it's worth your money.


The second thing you need to look at is dosages. Your product can contain good ingredients, but if they're being underdosed, they still won't work optimally.

So it's always essential to check whether or not your product contains a sufficient dosage of each ingredient.

You'll also want to avoid proprietary blends, as they don't specify the dosages for each ingredient. That's a no-go, as you don't know what you're getting.


Of course, you should also be looking at what kind of reviews the product has. The reviews can tell you how others who have purchased the caffeine free pre workout have experienced it.

If a product has a lot of positive user feedback, chances are that you're dealing with a good and effective supplement. If it has a lot of negative, mixed reviews, that should already tell you more than enough.


Another factor to consider when purchasing a caffeine free pre workout supplement is the taste. A pre-workout supplement with an unpleasant or overly strong taste may be difficult to drink, which can be a deterrent to consistent use.

On the other hand, a supplement with a pleasant flavor can make the pre-workout experience much more enjoyable. Most of the products we've shown you come in multiple flavors, so there's plenty to choose from.


Lastly, we look at the price of the product. Caffeine free pre-workouts will usually cost anywhere from $30 to $55.

Products at the lower end of the price range usually won't be the best, since they won't have an impressive ingredient profile.

We found that spending the extra money for a product that has high-quality ingredients with optimal dosages is worth every penny.

The Benefits Of Caffeine Free Pre Workouts

Of course, there's a reason why caffeine free pre workouts have exploded in popularity - that's because they come with a lot of benefits.

Many of you will want to know how this supplement can benefit your performance. Keep reading as we break down every one of the benefits.

Improved Muscle Pumps

One of the main effects you'll notice from taking a caffeine pre workout is that you'll get much better muscle pumps during your workouts.

That's because many ingredients in these supplements aim to increase nitric oxide levels in the body. Nitric oxide is a vasodilator, meaning it helps widen the blood vessels.

Caffeine free pre workout benefits

When you increase nitric oxide production, more blood, oxygen, and nutrients are able to reach your muscle cells. That's going to result in enhanced muscle pumps. Try it out during a pull day workout or push day workout, you'll be blown away by the pumps.

So, if you're like us and absolutely love getting a skin-tearing muscle pump, you must get your hands on a caffeine free pre workout.

Increased Focus

Besides noticing a massive increase in pumps, you're also going to feel more focused throughout your training sessions.

The improvement in cognitive functions is also a well-known effect many users experience from caffeine free pre workouts.

The increased focus and alertness will help you get in the zone, allowing you to push beyond your limits.

Enhanced Exercise Performance

Pre workouts without caffeine are also excellent for boosting your entire workout performance.

Despite not containing any caffeine or other stimulants, you'll still be able to hit the weights with much more intensity and stamina.

All in all, you'll be able to get in a better workout session than you would without a product like this.

No Crash

We've all heard of or even experienced the well-known ''crash'' that some pre workouts can give you. Your pre workout wears off, and you're left feeling sluggish and unmotivated to do anything for the rest of the day.

Especially pre workouts containing a large amount of caffeine combined with other stimulants can cause you to crash hard once it wears off.

But that's why we absolutely love a good caffeine free pre workout - they do not cause any type of crash when they wear off, never.

You can take these products, enjoy a good workout, and be productive for the rest of your day.

Take It Whenever You Want

Another huge benefit of these supplements is that you can take a caffeine free pre workout whenever you want. That means that even if you take it late in the evening, you can do so without any consequences.

With pre workouts containing caffeine, you can't take them too late on the day because otherwise, they'll mess with your sleep. You'll be tossing and turning at night.

That won't be the case with these products, and you'll be able to enjoy them even during a late-night session. They won't mess with your sleep at all.

Better Mind To Muscle Connection

One benefit of caffeine free pre workouts that often gets overlooked is that they can help you increase your mind-to-muscle connection.

A good mind-to-muscle connection helps you properly stimulate the muscle group you are training. It can be beneficial when training a lagging body part.

That's mainly because these supplements help more blood and nutrients reach your muscle cells, thus allowing for a better contraction during exercises.

The Best Ingredients For Your Caffeine Free Pre Workout

The ingredients in a caffeine-free pre-workout supplement are extremely important, as they are the key components that determine the supplement's effectiveness in enhancing performance, pumps, and focus.

When it comes to choosing a product, it's essential to look for ingredients that have been clinically shown to be effective in scientific studies. Here are some of the most commonly used and researched ingredients:


One staple ingredient that should always be included in a caffeine free pre workout, no matter what, is L-Citrulline.

L-Citrulline is a nonessential amino acid sourced from watermelon. It's proven scientifically to be extremely promising for boosting nitric oxide (N.O) levels.

Increasing nitric oxide will shuttle more blood to the muscles, giving you much better muscle pumps.

But that's not all; L-Citrulline will also boost aerobic exercise performance. Long story short, it's got to be included for maximum effects.


Another superior ingredient that is often found in caffeine free pre workouts is Glycerol powder.

Glycerol works uniquely, as it helps your muscles retain more water. This allows the muscles to stay hydrated during a workout and provides a better muscle pump.

Caffeine free pre workout ingredients

You'll commonly find patented types of glycerol in pre workout supplements such as Glycerpump and HydroMax.

It's also good to know that glycerol supplements positively impact exercise performance, making them an amazing ingredient.

Beet Root Extract

Next up, we've got Beet Root extract. Many of you will be familiar with beets but not with the unique benefits they can have.

This root vegetable is often included in pre workouts and nitric oxide boosters because it's rich in nitrates. Nitrates are highly effective for increasing nitric oxide, resulting in better, more intense pumps while training.

It could also improve vascular function and insulin resistance.


Betaine (Trimethylglycine) is a staple ingredient found in many caffeine free pre workout supplements. It's an amino acid that impacts many bodily functions.

There's a reason why it's often added to fitness supplements, and that's because it comes with numerous benefits. For one, it can help increase strength and power and improve body composition. That's why you'll often find Betaine in muscle building supplements.

In other words, Betaine is a must-have.


L-Tyrosine is a nonessential amino acid responsible for producing catecholamines, such as adrenaline and dopamine.

What makes L-Tyrosine an excellent addition to a pre workout is that through its unique mechanism, it has been shown to improve cognitive functions.

It will help you with the focus aspect of your workouts, ensuring you're in the zone and ready to hit the weights.


Choline is a crucial nutrient that plays a role in many bodily functions. For example, your brain needs Choline to regulate memory and mood.

Supplementing with Choline can offer many benefits, the most noticeable being an increased focus. Besides that, it may also positively impact post-workout recovery.

Black Pepper Extract

Black pepper extract, also known as Piperine, can help the absorption of nutrients. That's why many pre workout supplements finish their formula with a small amount of Black pepper extract - it helps the uptake of the other ingredients.

Increasing the uptake of the other nutrients in your product will kick in faster, and you'll notice the effects better.

Frequently Asked Questions

Below you'll find the questions we get asked the most about caffeine free pre workouts.

The Bottom Line

Even though caffeine is a popular and effective stimulant in pre workouts, it can also have adverse effects. That's why some of us aren't big fans of this stimulant.
