Written by Isaac Robertson

People want to get the most from their workouts. That’s only natural.

In order to do so many wind up employing their pre workout in the form of a cup of coffee, espresso, or an energy drink.

Why? Because caffeine works.

Unfortunately, it also works when it comes to producing jitters, mood swings, and insomnia.

So the price for using it to jumpstart a workout can be unacceptably high.

Not to fear, because the best caffeine free pre workout supplements are here and many are every bit as effective as is. 

But which is the best? Below, we’ll take a look.

Say what you want about caffeine, but it's a naturally occurring compound.

One concern many people have with the best caffeine free pre workout supplements is that some of them achieve their effects through artificial means.

This isn't the case with this USDA Certified Organic Powder.

What I liked a lot is the taste - especially lemon berry. 

It will power you through your workout with it's orgnaic ingredients. Things like maca root, ginseng, eleuthero root, yerba mate and rhodiola rosea.

What Ingredients Should You Look For?

Supplements packaging Nutrition Facts

​Some folks think that the best caffeine free pre-workout is determined ​by its ​content. There are ​ingredients that should be in your supplement to ensure that you're getting the best out of it. [1]

In addition, it's often helpful if the product label includes certifications from consumer protection groups including Informed Choice, NSF or the BSCG. [2]

​If you see these certifications, you can have a high degree of confidence the product is safe and effective.​

​Informed Choice, BSCG, and NSF offer reputable supplement certification programs that test products for banned substances in sport and provide databases with products and lots that have been certified to be free of drugs.

​As for the ingredients themselves look for:

  • ​Beta-alanine - This amino acid helps prevent the buildup of lactic acid while also promoting greater endurance and muscle recovery.
  • ​Creatine - Creatine is well known for its ability to promote muscle growth.
  • ​Magnesium - Magnesium is important when it comes to enabling proper muscle contraction.
  • check
    ​Vitamin D - Vitamin D also helps enable proper muscle contraction and plays a key role in promoting faster recovery.
  • check
    ​Beetroot - Beetroot provides for a better pump and longer endurance.
  • check
    ​Alpha GPC - This is a brain booster that helps you clear your mind and stay focused.
  • check
    ​Peak ATP - Promotes hard, lean muscle that is thick and strong.

Your pre workout doesn't have to include all of the above, but it should include most.

What ingredients Should You Avoid?

When looking for things that should not be in your non stim pre workout supplement the first red flag should be the phrase "proprietary blend."

Manufacturers often invoke the proprietary blend when they have something to hide. 

With the PB designation in place they don't have to list how much of which ingredient is included. Which means they can scrimp on more expensive (and more effective) ingredients without you knowing.

Beyond the proprietary blend, however, you'll also want to avoid:

woman avoiding gesture
  • ​Synephrine - This is a fat burner that also happens to be a banned substance in most athletic circles. It also has the potential to cause serious health problems.
  • ​Yohimbe - Typically used for weight loss this is a stimulant with unpredictable side effects and questionable effectiveness.
  • DMAA - May result in shortness of breath or tightness in the chest that is a precursor of a heart attack. Also a no-no for people with high blood pressure.
  • check
    Caffeine - Look for caffeine to be hiding in products that are cagey about their makeup and hide behind phrases like "all natural." Remember that it is a natural compound.

Our ​#1 Caffeine-Free Pre-Workout Is...

It can be hard to find a pre-workout supplement that shows such great results without containing caffeine. While you can choose any of the above pre-workout supplements, I would recommend Pumpsurge Stimulant-Free Pre-workout.

With no caffeine, artificial sweeteners, colors, and preservatives, it makes this one of the most natural pre-workouts out there - perfect for anybody looking to go the natural route, especially vegans. Additionally, with zero caffeine, I don’t get the “crash” side effect like a typical pre-workout.

With the nootropic pump formula, I really feel I have sharper mental focus during my workouts.

I recommend you buy it through the official site as there’s lots of fakes out there. They also have a 100% hassle-free money-back guarantee.

  • Thanks for explaining the benefits of stimulant free pre-workout supplements. But are there other cons of taking supplements with caffeine aside from the jitters? I’m torn between with or without caffeine.

    • Hey Robert! That’s a nice question you have there. Other known side effects of taking pre-workout supplements with caffeine are increased blood pressure, heart palpitations, dehydration, insomnia, adrenaline fatigue, and some experience energy crash. I highly recommend that you go non-stim to avoid these side effects while powering up at the gym.
