For those of you that are in a hurry and can’t read the review, we recommend Genius Pre Workout Powder as the best non stimulant pre workout.

We’ve all been there. Buying a new pre workout and going to the gym to try it, like a kid going to Disney.

Then it hits you and this pre workout makes you feel better and makes you look better than the last. You absolutely crush your workout with your new friend and then a half hour later, your life stops.

You feel like you woke up from a week long bar crawl. And now you’re here trying to find a way to avoid it from ever happening again.

These are the Best Non stimulant Pre Workouts we Reviewed:

What is non stimulant pre workout?

Everyone knows what pre workout is. It’s the powder that makes you feel great during your workouts and that you refuse to admit you’re hooked on. It boosts you up, makes you work harder, increases your focus, and then most times ends in a hangover-like crash. This is a result of the stimulant within your pre-workout, most likely caffeine.

A non-stimulant pre workout is a variation of pre workout that doesn’t contain a stimulant. Instead of a stimulant, it uses natural ingredients to aid you. These natural ingredients can give you the same benefits as stimulant fueled pre workout without the side effects.  

Is it stimulant free?

Although caffeine is the most popular stimulant in pre workout and the world, they can come in many different shapes and sizes. Common stimulants can be Yohimbine, Synephrine, and DMAA. Most people don’t understand a word on their bottle, so keep an eye out for these staple ingredients in your non-stimulant pre workout:  


L-Citrulline helps you achieve the most sought after thing while working out, a pump. It improves your blood delivery in your body, which increases the size of your pump. Perfect. It also helps muscle growth by elevating your growth hormone and protein synthesis levels.  


The amino acid, Betaine, packs a real punch. By increasing your strength, power, stamina, and endurance, it’ll help you finish off that last set.  


This compound handles your brain and its activity. It helps by raising your awareness and focus during your workout.  


Beta-alanine can slow or stop the production of lactic acid during your workout. Lactic acid is what makes you feel fatigued and weak during your workouts by building up in your muscle. This can help you cruise through those extra couple of reps at the end of your set.  

What to Avoid

When trying a non-stimulant pre workout you should avoid proprietary blends. Proprietary blends are mixes of ingredients and compounds, put together by the company. Oftentimes in these blends, they can be dishonest on what is truly in them. They also usually only give the dosage of the blend and not the individual ingredients. Making what you are taking even more cloudy.

You should also try and avoid artificial flavors in your pre workout. It’ll help to make it even more natural and less full of chemicals. You can find natural flavors that taste the same or even better than the artificial flavors.  


There are a multitude of benefits for your health in using a caffeine free pre workout. Here are a few:

More Peaceful Sleep

This one is for the people who workout after work or at night. Sometimes you take your pre workout a little too late and it doesn’t wear off as soon as you expect. It then interferes with your sleep later on in the night, with discomfort and/or insomnia. By taking a non-stimulant pre workout, you wont have to worry about that.

Avoid a Crash

Your chemical fueled workout feels amazing during its course, but no one enjoys the come down. By switching to stimulant free pre workout you can avoid that crash, while enjoying your workout just as much.  

Feeling Better

Most stimulants have a long list of side effects and you have most likely endured some before or after your workout. Common side effects include: headaches, jitters, anxiety, irregular heartbeat, diarrhea, and withdrawals. Switching to non-stimulant pre workout can help you avoid these. You can also feel the difference in your attitude and health after you switch.

How to Choose

The next step is choosing your stimulant free pre workout. There are certain things you want to look for when making your choice too. You want to try and pick a product that is all natural and if possible naturally sweetened. You want to avoid any added sugars or any banned substances.

Due to most people not being able to (as much as they say they can) get off their stimulant fueled pre workout, you have to compromise. We recommend you try and phase in a stimulant free pre workout. Try the non-stimulant on pull day or every other day, until you can rely on the non-stimulant pre workout alone.
