Best Stim Free Pre-Workout Review 2020 – Non-Stimulant Supplements

A Stimulant Free Pre Workout can be one of the best additions when it comes to your energy levels with every training session. Since caffeine or Synephrine can come with jitters for many people, it is recommended to use one of the safer alternatives. So where do these Pre Workout Supplements get their energy from? Since there are some safer ingredients which can fuel your workout and offer good results within an hour of training, most of them can come with ingredients based in BCAAs. This means that you can expect energy sources to come from Beta Alanine, Citrulline and even Taurine. These can be found together with other ingredients which are also safer for most people.

Together with ingredients such as Arginine or various minerals, you can see better vascularization and improved muscle support for proper results with your training routine.

How to Choose a Stimulant-Free Pre-Workout Supplement?

Making the right decision is always influenced by a few characteristics which are hard to see as a beginner, apart from the ingredients’ list. One such example comes with the power of adaptation of your body, which is rarely described by the manufacturers. This means that most solutions will eventually start to come with reduced results in time. One of the best plans from this perspective comes with the cycling of the pre-workouts, even those with no stimulants such as caffeine.

Power of Adaptation

As mentioned above, the power of adaptation of the human body is impressive. It will eventually adapt to the ingredients you consume and this includes the pre-workouts. This is why it is important to see the pre-workout as a solution which you use in cycles rather than all the time. Another interesting approach comes with actually using the pre-workout only when you need the extra energy boost. Thus, if you had a perfect recovery and enough sleep from your previous workout, you might not need to use the supplement to push your limits.

Since there are many great products on the market, you can also switch them up but since all users tend to have a favorite brand, it is recommended not to become dependent on the supplement and it is thus recommended to use it alternatively only when needed.

Ingredients’ Safety In Stim Free Pre-Workouts

One of the main concerns within the supplements industry as a whole comes with the safety on the ingredients. For most pre-workouts, you will see that almost all potentially harmful ingredients have been excluded, especially with the stimulant-free solutions. This is why it is so important to know that you can see great overall results when looking for a safe solution and one which is also made to offer you the performance you need.


As with most supplements, the flavors are among the first things to consider. Since there are so many flavors to choose from, it is recommended that you only choose the pre-workout which comes with the flavors you like. Apart from the preferences’ point of view, it is also important to know that you can see great results with the solutions which allow you to maintain good focus during the workout and which will not come with side-effects such as reflux or acid which in many cases can be caused by a flavor you dislike.

Beta Alanine, Citrulline and Taurine

Since you cannot count on caffeine, there are a few amino acids which can successfully replace it. Take Citrulline for example. It has become so popular over the past few years that you can even find pre-workouts which only come with this sole ingredient to boost your energy levels. It is considered safe for most people and it can be one of the solutions to use when it comes to improving your training performance.

Beta Alanine and Taurine are also viable alternatives. They can be seen in different quantities in most modern pre-workouts. They are used for their results and for their relative safety when it comes to jitters. This is why they represent recommended options when it comes to better energy and mental clarity.

These micronized ingredients are also easily absorbed. This means that they have the quality which is needed when it comes to great results within minutes. Since most people take pre-workouts strictly before training, this becomes a major plus. Thus, with a fast action and proven results, Citrulline, Beta Alanine and Taurine can offer you the much-needed support when you want to push your physical limits.


The minerals in some of the pre-workouts can also come with some advantages. Of course, they tend to favor the longer workouts where you would need to replace what you lose thorugh sweat. But they can actually be a good solution for most people as they can provide the electrolytes to support muscle activity.

They can be important in the conditions in which they can help you train safer and longer, keeping cramps away. This is why it is important to know that you can see great overall results when it comes to better training capacity, especially if you plan to have longer training sessions.


Arginine is among the popular ingredients in many pre-workouts. It can also be found independently as it comes with a strong vascularization action. This makes it a good solution when it comes to better overall results with oxygenation and better nutrient distribution in the blood vessels.

It is considered to be among the safe ingredients and this is why it can be one of the solutions to consider in a blend with other ingredients which can support your efforts to find more energy with no caffeine.


Some of the pre-workouts on the market come with antioxidant support as well. Seen in the form of different extracts, it acts well when it comes to a better immune system and a boosted metabolism. So what are some good examples in this category? Some products can come with Red Clover extracts, Ginseng extracts or Japanese Knotewood extracts. Of course, the problem with these ingredients is that are not mandatory in your nutrition and their concentration is thus established entirely by the manufacturer.

This doesn’t mean that they cannot offer good results, especially on the long-term. Some of them can have a role in energy while other might act as a long-term plus as Creatine. This is where they can prove a good addition to keep your body away from different inflammation due to intense physical activity levels.


One of the much-discussed areas with pre-workouts comes with vitamins. So should you look for a supplement which comes with vitamins? The answer might depend on your needs. If you are not taking vitamins separately and still hope to train at the highest level, these might be the alternatives for you. At the same time, it is also important not to dismiss a good product just for the lack of vitamins.

The sources of the vitamins are also important as their quality can determine their true benefits to the body. Thus, if you plan to use a pre-workout which comes with added vitamins, you can at least ensure that the vitamins are of high quality, just as the rest of the ingredients. If you are already taking a multivitamin and meeting your daily recommended intake, the extra vitamins you consume will only be excreted by the body. This is why you need to look at the pre-workout in relation with your foods and other supplements if you want the best results.
