The 5 Best Stimulant Free Pre Workout Supplements (2023)

Choosing stimulant-free pre-workout supplements instead of pre workout supplements that contain caffeine or other stimulants can be a great decision for your overall health, but you still want a pre workout that helps you crush your workout, right?

Fortunately, there are many stim-free pre workout ingredients that will be a huge boost to you and your workouts! Believe it or not, non-stim pre workout supplements can give you as much energy as the pre workout supplements that contain loads of caffeine!

The reason to choose a stimulant free pre workout supplement is simple: although it is safe to consume moderate amounts of caffeine, drinking pre workout products with a large amount of caffeine can have negative effects on your health.

By choosing the right stim-free pre workout supplement, you can boost your workout intensity and limit your caffeine intake.

Let’s learn more about the best stimulant free pre workout supplements:

What are the Best Stim Free Pre Workout Ingredients?

Caffeine free pre workouts offer energy and focus through a variety of ingredients, such as natural nootropics. Although caffeine is the most well-known nootropic in the world, there are many other common nootropics for energy that are not “stimulants.”

From plant extracts to amino acids, there are many natural sources of energy that stimulant free pre workout supplements use.

As always, it is important to choose the products which work for you.

In my opinion, here are the best stimulant free pre workout ingredients that you should make sure are in the stim-free pre workout supplement you choose:

Citrulline Malate

Citrulline malate is one of the few dietary supplements which has clinical research to verify its benefits. In fact, multiple studies have proven the benefits of citrulline malate for improving workout performance.

When you use citrulline malate before your workouts, you can notice benefits such as:

• More Muscle Endurance
• Less Muscle Soreness Post-Workout
• Increased Work Capacity
• A Bigger Muscle “Pump”

I suggest that you look for a stim free pre workout that contains about 3-6 grams of citrulline malate.

Beta Alanine

Another clinically researched stim-free pre workout supplement ingredient is beta alanine.

The primary role of beta alanine is to improve your workout capacity. Beta alanine works by creating a buffer that slows down the build-up of lactic acid, helping your muscles perform normally for longer.

For beta alanine, the best possible dosage is ~3.2 grams per day, taken over the course of small dosages throughout the day. Personally, I have found the best results when I can take 4 doses of 800mg of beta alanine per day.

Beta alanine also works synergistically with creatine monohydrate, one of the other top stim free pre workout ingredients on my list!

Creatine Monohydrate

Of all the caffeine-free pre workout product ingredients, creatine monohydrate is probably the most well-known. Creatine monohydrate is another workout capacity enhancer, and it also plays a tremendous role in helping you build more lean muscle mass.

The main role of creatine monohydrate is to draw more water into your cells, which provides you with greater strength and endurance overall.

If you are only getting your creatine monohydrate in your daily pre workout product, your pre workout should include at least 5 grams of creatine monohydrate.

However, some people prefer to begin with a “loading” phase of up to 25 grams of creatine monohydrate per day for the first week.

Although there are other forms of creatine, I only use creatine monohydrate because it is well-researched and effective.

BCAAs or EAAs

BCAAs or EAAs are vital to your stimulant-free pre workout supplement because they provide your body with easily accessible sustained energy.

Amino acid supplements that contain either BCAAs (branch-chain amino acids) or EAAs (essential amino acids) provide quick fuel for your muscles while also providing a lasting fuel source for your body overall.

Drinking amino acids before your workout will help improve your muscle recovery time and also help you train more intensely without becoming fatigued. Amino acid supplements have also been shown to improve muscle strength and increase lean muscle mass.

I suggest that you drink between 5 and 10 grams of amino acids before your workout, so try to find a pre workout product that includes this much!
