TL;DR – Summary

  • Most pre-workout supplements feature caffeine or similar stimulants, yet certain ingredients can enhance exercise performance with minimal or no stimulant impact.
  • Consuming Huperzia serrata, arginine, citrulline, cordyceps, Rhodiola rosea, essential amino acids, sodium bicarbonate, and chocolate milk before engaging in physical activity may enhance performance.
  • To optimize their effects, it’s crucial to take ingredients at varying times.
  • Pre-workouts are generally considered safe, but there is little research on their long-term effects.

So What Exactly is a “Pre Workout”?

A pre-workout is a supplement that is taken before a workout to enhance performance and energy levels. When evaluating a pre workout, it is important to look at the ingredients and their dosages to ensure they align with your fitness goals.

It is also crucial to be aware of any potential risks or side effects, such as increased heart rate or jitters. However, when used correctly, pre-workouts can provide numerous benefits including improved focus and endurance, which can lead to more effective workouts and better results. 

As always, it is important to consult with a healthcare professional before starting any new supplement regimen.

Caffeine-Free, Non-Stimulant Pre Workouts: Do They Work?

A common ingredient found in most pre-workout nutrition products on the market is caffeine. The effectiveness of many pre-workout formulas can be attributed to their caffeine content. 

Originally, the pre-workout supplement category was created to help individuals feel more energized during their gym sessions. However, it’s important to note that not all supplements intended for pre-training use are designed to stimulate.

If you prefer to steer clear of caffeine, or if you’re seeking benefits beyond alertness and focus from your pre-workout supplement – like enhanced pumps, improved endurance, or strength gains – there are alternatives available.

I’ve explored the top caffeine-free, non-stimulant pre-workouts that can boost your performance without leaving you feeling overly stimulated.

Where is the Proof?

First and foremost, a robust collection of research indicates that pre-workout supplements can significantly contribute to achieving fitness objectives. 

A comprehensive 2018 review by the Journal of the International Society of Sports Nutrition, which examined 80 different studies on pre-workout formulas, found that these supplements could enhance muscular endurance and improve mood during exercise. 

The authors further observed that, in conjunction with resistance training, pre-workout supplements could facilitate positive long-term body composition adjustments through the acquisition of lean muscle mass.

Potent Stimulant Dose

Let’s cut through the noise, shall we? Pre-workout formulas are like a mixed bag of tricks – some ingredients are the real deal, while others are not so much.

 It’s a real puzzle for scientists to figure out what’s actually doing the heavy lifting and what’s just taking up space.

And let’s talk about caffeine – oh, the beloved fuel of gym rats everywhere. With more than 300 milligrams in a single dose (yep, that’s like chugging three cups of coffee), caffeine is the undisputed champion of boosting power, endurance, and alertness as well as helping your body handle stress like a champ. 

But when it comes to pre-workouts, it’s hard to tell if it’s the caffeine doing all the work or something else in that “proprietary blend.”

But hey, it’s not all about the buzz. There are other stars in the pre-workout show that deserve some love, even if they don’t get your heart racing as caffeine does.

So, here’s the deal: navigating the pre-workout landscape can be tricky, but armed with a bit of know-how, you can make choices that fuel your fitness journey without the filler. Remember, it’s not just about what gets you hyped – it’s about what gets you results. 

What Pre Workout Supplements Contain Stimulants?

Let’s get one thing straight: caffeine isn’t the only game in town when it comes to stimulants in supplements. You might see “caffeine-free” or “no stimulants” slapped on the label, but don’t be fooled. 

These supplements can still pack a punch, especially if you’re the type who gets jittery with just a whiff of coffee. Everyone’s body reacts differently, so what sends you climbing the walls might not bother someone else.

Here’s the deal: understanding how your body responds to different ingredients is key. Not all supplements are created equal, and it’s about finding what works for YOU. It’s like navigating a minefield with a blindfold on, but hey, that’s where I come in.

Armed with decades of experience and a no-BS attitude, we’re here to guide you through the maze of supplements. I’ve seen it all, smelled all the stinky feet (don’t even get me started), and I’m still standing – ready to help you achieve your fitness goals without falling victim to the latest “miracle” supplement. 

Remember, knowledge is power, and in this case, it might just save you from a racing heart or a sleepless night. Let’s get to work, and let’s do it right.

Many people associate stimulants solely with substances that increase heart rate and stimulate the central nervous system. However, this category encompasses a broader array of compounds. 

What the Americans have to Say

According to the FDA in the US, a stimulant is any drug or substance that can enhance mental alertness or wakefulness when one is feeling fatigued. Therefore, practically any product that boosts mental energy could be considered a stimulant.

It’s important not to confuse “caffeine-free” with being free of stimulants. To ensure a product is entirely devoid of stimulants, it must explicitly state so on its packaging. 

Additionally, verifying that a product’s claims are supported by third-party testing – such as by Informed-Sport, which assesses supplements for safety and purity – is crucial for those seeking stimulant-free options.

For those avoiding stimulant-laden pre-workouts due to caffeine sensitivity, alternatives containing compounds with milder stimulant effects might be acceptable.

It’s worth noting that several ingredients typically marketed in these products do possess stimulant properties, often due to their caffeine content. 

Consequently, individuals cautious about stimulant intake should scrutinize products promoting these ingredients.

  • B-complex vitamins
  • Caffeine/caffeine anhydrous
  • Carnitine
  • Cocoa
  • Ginseng
  • Green coffee bean
  • Guarana
  • Ma huang
  • Taurine
  • Yerba maté
  • Yohimbe/yohimbine

For a comprehensive list, visit the Operation Supplement Safety website, an initiative by the U.S. Department of Defense.

Be mindful that the FDA deems these compounds safe for adult consumption in moderate amounts. They are not controlled substances likely to cause legal issues or pose significant health risks, assuming you are a generally healthy adult. 

If you’ve ever had energy drinks, sodas, teas, or chocolate, chances are you’ve already consumed some of these ingredients.

Top 5 Caffeine Free Pre Workout Options in the UK

There are always new brands and products when it comes to health and fitness supplements and most are usually the same thing in a new package or just random ideas on what the most potent stimulant dose may be. 

DO NOT BE FOOLED 

Always consult your dietician or doctor when making lifestyle changes or attempting to replace your diet plan with a caffeine free or stimulant free version!

The Kaged stimulant-free pre-workout supplement features a familiar blend of ingredients typical for non-stimulant pre-workouts in its price range. It includes BCAAs and creatine, which are known to aid in muscle retention, while the addition of coconut water powder ensures optimal hydration during your exercise session.

I’m all in on Kaged supplements; they’re top-shelf, no fluff, and you know exactly what you’re getting. Sure, I’ve only dived into the Cherry Bomb flavour, and let’s be real – it’s not winning any taste contests, but it powered me through my workout like nothing else. For those days when my training is a mix of cardio and lifting, this stim-free powder is my go-to.

Let’s cut to the chase: not every supplement out there is going to taste like a dream, especially when they’re packed with everything you need and nothing you don’t. But if you’re serious about crushing your workouts and not just sipping on something that tastes good, then Kaged is where it’s at. It’s about what works, not what tastes like dessert.

So, let’s not make excuses or settle for less. Grab the right supplements, push through, and let’s get those gains without any unnecessary fluff.

A visit to Kaged’s website reveals an impressive collection of over 160 reviews, boasting an average rating of 4.7 stars, while on Amazon, the product garners attention with more than 13,000 reviews and a solid 4.3-star rating. The consensus among most users, and one I share, is that while the product delivers excellent results, its taste leaves something to be desired.

Pre Kaged Stim Free stands out as a premium stimulant-free option, enriched with 2g of Taurine and 1.85g of Tyrosine to enhance focus. Its comprehensive ingredient list places it at the premium end of the pre-workout spectrum. However, considering the quality and range of components it offers, I firmly believe it represents great value for its price.

  • Ample servings of almost 30g of active ingredients
  • Vegan-friendly & mixes easily
  • 4 Patented ingredients
  • Third-party tested & Informed-Sport Certified
  • Only 20 servings
  • Slightly bitter aftertaste

Are you on a budget, or perhaps new to the world of supplements and hesitant about investing in a pre-workout? Consider trying Nutricost’s stimulant-free pre-workout as a viable option.

At an affordable price, this stimulant-free pre-workout stands out by offering high quantities of nitric oxide-boosting ingredients, surpassing even some of the pricier alternatives. With 6 grams of citrulline, it’s designed to enhance nitric oxide levels, thereby increasing blood flow and enabling more pronounced muscle pumps.

Having personally used Nutricost’s pre-workout, I can attest to its value for money – there’s simply no better option available at this price point. It’s my go-to recommendation for clients seeking effective yet budget-friendly pre-workout solutions. The Sour Grape flavour is a particular favourite of mine; it not only mixes well but also delivers a delightful taste experience.

Nutricost is a favourite among Amazon shoppers, and its stimulant-free pre-workout is no exception, boasting over 500 reviews with an average rating of 4.1 stars.

  • Optimized ingredients with scientifically backed dosages

4. PUMP SERUM STIM-FREE

Product Breakdown:

  • Key Ingredients: Citrulline 8g, BCAA 6.5g, GlycerPump 3g, Betaine Anhydrous 3g, Beet Root Extract 2g, Agmatine Sulfate 1.5g
  • Total Servings: 25
  • Price Per Serving: $2.20
  • Grams Per Serving: 31g
  • Flavours: Strawberry Mojito, Cherry Berry, Island Dream
  • Company Founded: 2019

Pump Serum is a great stim-free pre-workout without stimulants. For those stimulant-sensitive individuals, this might be their best bet. Pump Serum is easily one of the best caffeine-free pre-workouts on Amazon, and I highly recommend you give it a shot.

Huge Supplements has become a trusted supplement brand in a relatively short amount of time. I first tried Pump Serum last year and it delivered on its name, I got some ridiculous pumps using it. Popular opinion may slightly disagree with this pick as it only has 3.7 stars on Amazon with over 180 reviews. The common complaints around Pump Serum are that the product is clumpy and it’s overpriced. 

I’d like to point out the fact that the 3g of GlycerPump is most likely the reason for the clumping and this ingredient helps produce some massive pumps when working out. 

Pump Serum contains ten core ingredients, which are clinically approved doses that are proven to help increase focus, and blood flow and boost muscle pumps in the gym. 

To make this pre-workout even better, it contains GlycerPump, which effectively and dramatically enhances your muscle pumps.

  • 13 research-backed ingredients
  • Massive 31-gram serving of active ingredients
  • Contains GlycerPump
  • 4 proven patented ingredients
  • Iffy availability

5. AXE & SLEDGE HYDRAULIC (stimulant-free version)

Product Breakdown:

  • Key Ingredients: Citrulline 5g, Glycerol Powder 3g, Beta Alanine 2.4g, Taurine 2g, Agmatine Sulfate 1g, 
  • Total Servings: 20
  • Price Per Serving: $1.5~$2.25 depending on flavor
  • Grams Per Serving: 20.5g
  • Flavours: Gummy Bear, Shark Bite, Tropical Thunder, ICEE Blue Raspberry, ICEE Cherry, Unicorn Blood
  • Company Founded: 2019

Most users can benefit from it. Moreover, with a maximum scoop containing 2,400 mg of Beta-alanine, you’ll notice a significant boost in performance. This includes an increase in your body’s exercise capacity and endurance, as well as a reduction in muscle fatigue.

Axe & Sledge Hydraulic also contains several standard ingredients for enhancing the pump in pre-workout supplements, such as L-Citrulline, Glycerol, and Agmatine Sulfate. Overall, this supplement is of high quality and is well-formulated.

While I haven’t personally tested this pre-workout, my confidence in its effectiveness comes from its creator, IFBB Pro Seth Feroce, renowned for his intense training sessions and straightforward approach. Based on the formulation and genuine customer reviews, I’m convinced it’s an excellent choice for those seeking an improved pump. The product boasts over 500 reviews with an average rating of 4 stars. Most negative feedback mentions the product’s tendency to clump, which, as you may know, is attributed to the Glycerol Powder.

Though it may fall short in enhancing focus, Axe & Sledge Hydraulic stands out as an exceptional choice for achieving an impressive pump.

  • 5 patented ingredients
  • Delicious flavours
  • 1.5g Creatine
  • Not much emphasis on focus ingredients
