A good pre-workout supplement can really take your workout performance to the next level. The problem is many of today’s pre-workout supplements contain caffeine and, in some cases, a tremendous amount of caffeine. Some pre-workouts have twice the caffeine of a Monster energy drink which is a lot.
For those who are looking for a pre-workout supplement that does not contain caffeine, there are some good options available. Here is a look at the best pre-workout supplements without caffeine.

Missing some key ingredients like Citrulline Malate

When choosing a stim-free pre-workout, there are a few things you should look for:
Ingredients
The first is key ingredients like Beta-Alanine, Citrulline Malate, Betaine Anhydrous, and Creatine.
These ingredients have been scientifically proven to help with pumps, focus, endurance, recovery, and muscle building. You will find these ingredients in most pre-workout supplements, and for a good reason, they work.
Doses
The second is doses. You want to make sure that the doses of each ingredient are disclosed and that they are effective doses.
You also want to make sure that there are no proprietary blends, as these can hide underdosed ingredients.
Purity
The third is purity. You want to make sure that the pre-workout has been third-party tested for banned substances and that it is free of fillers and other junk.
Flavor
The fourth is flavor. This is a personal preference, but you want to make sure that the pre-workout tastes at least decent.
No one wants to drink something that tastes like garbage on a regular basis.

What are the Benefits of Stim-Free Pre Workouts?
There are a few benefits of stim-free pre-workouts. The first is that they are safe for those with sensitivities to stimulants, obviously.
The second is that they can be taken any time of day, as they won’t interfere with sleep. This is a nice bonus for those who work out in the evening.
The third is that they tend to be less expensive than pre-workouts that contain stimulants.
The fourth is that they are often more focused on pumps, increased blood flow, muscle gains, and endurance rather than just energy.
While most pre-workout supplements include a form of stimulant, like caffeine or noradrenaline (norepinephrine), some don’t. These supplements work on the central nervous system to increase your heart rate and motivation throughout workouts—especially by blocking adenosine receptors from feeling tired.
Stimulant-free pre-workouts use other methods to increase energy, such as improving blood flow or delivering more oxygen to muscles. This can be done with ingredients like l-citrulline, nitrates, and beetroot powder. These supplements are an excellent option for those who are sensitive to stimulants or those who workout late at night and don’t want to have trouble sleeping.
Ingredients to Look for In Stim-Free Pre Workouts
If you want a solid pre-workout supplement that has everything you need without caffeine then look for these ingredients:
Citrulline Malate
Citrulline malate is a compound made up of the amino acid citrulline and malic acid. It is found naturally in watermelons but can also be manufactured in a laboratory. Citrulline malate has a number of benefits when used as an ingredient in pre-workout supplements.
It has been shown to Increase strength, aerobic performance, and muscle endurance [1,2]
It also has been shown to increase nitric oxide, which means more blood flow and better pumps. [3]
Beta-Alanine
Beta-alanine is a non-essential amino acid that is produced naturally in the body. It is also found in some foods, such as meat and fish. Beta-alanine has several benefits, including improving training sessions, reducing fatigue, and increasing muscle mass. [4]
When beta-alanine is supplemented, it can increase levels of carnosine in the muscles. Carnosine is a compound that helps to buffer lactic acid, which can build up in the muscles during training sessions and lead to fatigue. By reducing the amount of lactic acid in the muscles, beta alanine can help improve exercise performance and reduce fatigue.[5]
Betaine Anhydrous
Betaine anhydrous is a compound that is found in many classic pre-workout supplements. It is often used as a performance enhancer, as it has been shown to improve power output and muscular endurance. Betaine anhydrous can also help to increase muscle growth and protein synthesis. In addition, betaine anhydrous may also help to reduce body fat. [6]
BCAAs
BCAAs are a group of three essential amino acids – leucine, isoleucine and valine – which the body cannot produce on its own. Therefore, we must obtain them through our diet or supplementation.
BCAAs play a crucial role in muscle growth and recovery, making them a popular choice amongst athletes and bodybuilders. When taken before or during exercise, BCAAs can help to delay fatigue, improve performance and reduce muscle soreness afterward.[7]
BCAAs are also often used as a post-workout recovery aid, as they can help to stimulate muscle protein synthesis and promote the repair and growth of muscle tissue.
Taurine
Taurine is an amino acid found naturally in the body and plays an important role in many bodily functions. It is also a common ingredient in pre-workout supplements, as it has been shown to improve athletic performance.
Taurine is involved in numerous processes in the body, including muscle contraction, heart function, and brain development. It also has antioxidant properties and can help to protect cells from damage.
And when Taurine is used alongside BCAAs, it has been found to reduce next-day muscle soreness more than either taken independently [8].
Pros and Cons of Caffeine-Free Pre-Workouts
There are pros and cons to consider before deciding if a stim-free pre-workout is right for you.
Pros
Can be taken any time of day without worrying about affecting sleep
Great for those who are sensitive to stimulants or have trouble sleeping when they workout late at night
Still provides many of the same benefits as pre-workouts with caffeine, such as increased strength, endurance and pumps
Typically less expensive
Cons
May not be as effective as pre-workouts with caffeine for those who are looking for a major energy boost
Still contains Beta-Alanine which gives you the tingles which some don’t like
If you want to get the most out of your workout without the jitters, try one of these caffeine-free pre-workout supplements. With a little trial and error, you’re sure to find the perfect supplement to help take your workouts to the next level.
