What Is The Best Stimulant Free Pre Workout – You Can Still Get Pumped

Whether you are Caffeine intolerant or just trying to limit your daily Caffeine dose, you will want to know, what is the best stimulant free pre workout.  The majority of pre workout supplements are packed full of Caffeine based stimulants making it difficult to find a good one that doesn’t contain it.

Based on market research, my personal experience and reviews, I’m going to introduce some of the best Caffeine free alternatives.  Great stimulant free pre workouts do exist, and I’m going to list them as well as the benefits and negatives of each.

I’ll also go over the zero Caffeine pre workout differences as well as what ingredients are substituted to give you that energy and enhanced performance.


What Is The Best Stimulant Free Pre Workout - caffeine free logoWhy Stimulant Free Pre Workout

The most popular pre workout supplements contain between 150-300mg of Caffeine per serving, with some of the highest up to 400mg.  This is like drinking 2 to 7 cups of coffee at one time.

This amount can be enough to make a lot of us feel like we’re crawling out of our skin.  Many of us just don’t care for the way that Caffeine makes us feel or it can make us sick.

Caffeine Addiction

Caffeine is the most addictive legal stimulant out there and is classified as a drug because of the way that it reacts with the central nervous system.  The temporary energy boost and increased motivation come with a strong crash soon afterward.

Even worse, the addictive effects have you going back for more to avoid going through Caffeine detox.  It can take more than a week for your body to sluggishly and painfully get over the lack of this stimulant.

Caffeine Tolerance

Another thing to consider about Caffeine is tolerance.  This is a very real thing that happens when your body gets use to higher quantities of Caffeine.  After a time, your body develops this tolerance to where Caffeine is not effective anymore.

This starts out by having to take more and more to produce the same effect and ends up that no amount of Caffeine will work.   At this point, this can be quite unhealthy and it is best to take some time off from Caffeine all together.

Caffeine Allergies and Intolerance

Other reasons for avoiding Caffeine are blatantly obvious.  Some people are Caffeine intolerant or even worse, a Caffeine allergy.

With intolerance, this is basically a sensitivity to this stimulant.  It starts with the way their body metabolizes this chemical.  A small amount of Caffeine will affect them as if they took a large amount.  Intolerance to Caffeine can result in headaches, anxiety, and lack of sleep.

A Caffeine allergy is a little more serious and it is recommended to avoid Caffeine completely.  This allergy usually comes from your genetic makeup.  It causes some of the same reactions as intolerance but will also show rashes and red bumps, swelling of lips and tongue, itchy mouth and even hives.

What Takes The Place Of Caffeine

What Is The Best Stimulant Free Pre Workout - amino acid molecule

Until they come out with a stimulant free “magic bullet” you will never get quite the same effects from the ingredients in a zero Caffeine pre workout.

However, a pre workout powder is still a complete performance and strength building supplement without this stimulant.  Certain Amino Acids such as Beta Alanine will help to increase your energy naturally.

Citrulline may be the most important Amino in a Caffeine free pre workout.  This is what helps to manufacture more Nitric Oxide through a chain of events.  Nitric Oxide is the key ingredient to get what is referred to as a muscle pump.

This is where your veins are vascularized to be able to carry more nutrients and oxygen to your muscles as well as keep them hydrated.   When this happens, you will be able to have a more intense workout, longer endurance and less rest between exercises.

What Is The Best Stimulant Free Pre Workout - scientists in a labStimulant free manufacturers have to be a little more creative with their ingredients.  Because of this, they tend to use better and higher quantities of certain Amino Acids.  The ingredients in Stimulant free pre workouts are designed to give you sustained and slow release energy to get you through to the end of a workout.

A few Caffeine free pre workouts include thermogenic ingredients.  These promote weight loss while you are getting toned and building muscle.   Thermogenics boost your metabolism giving you more energy and burning calories faster.  A few ingredients to look for are Cayenne or Capsicum, CLA, L-Carnitine and green tea extract(which may contain small amounts of Caffeine).

Stim-Free Ingredients:

  • Branched Chain Amino Acids (BCAA’s)
  • Arginine Alpha-Ketoglutarate
  • Citrulline Malate
  • Beta Alanine
  • Vitamin B’s
  • Minerals (Electrolytes)
  • Creatine Monohydrate

Benefits Of Going Stimulant Free

Stimulant free pre workout popularity is on the rise.  You don’t have to go to the gym with that jittery, overly wired feeling or deal with that post workout crash.   While you may not get the Caffeine energy with these supplements, it will still provide you with the muscle pump and increased strength.

It is the Amino Acids in a pre workout that provide you with the endurance and keep you from fatiguing.  There will be less rest time between exercises and increased muscle performance.

A Caffeine free pre workout will actually give you a bigger pump and more endurance than one with Caffeine.  The reason for this is that they are designed to work as a vasodilator to enlarge your veins to bring more oxygen and nutrients to your muscles.  Caffeine is a vasoconstrictor which works to hamper these effects and reduces blood flow during exercise.

Another negative for Caffeine is its effect on Creatine.  Because of this, Creatine is more effective for building muscle and increasing performance in a stimulant free pre workout.  Caffeine will actually work against the positive effects that Creatine brings.

What Is The Best Stimulant Free Pre Workout - me holding container of pre workoutThe fact is that you may not get the same energy rush and motivation without Caffeine.  However, there are many pre workout benefits that come with going without it.  It’s the Amino Acids in a pre workout that really gives you the strength and endurance advantages.

Also, the effects of some of the important ingredients such as Citrulline and Creatine are actually hampered by Caffeine.  If you are sensitive to Caffeine, you won’t have to worry about the jitters, anxiety or sleepless nights.
