Pre workout for endurance

In this article, I will discuss the benefits of pre-workout supplements for endurance, along with their detailed ingredient profile and potential drawbacks.

Pre-workouts are designed to help you increase focus, energy levels, and endurance, which is essential before you hit the gym.

They cannot be just used for gym purposes but also for many unconventional uses that require much endurance and physical exertion.

Whether you’re an athlete, fitness enthusiast, bodybuilder, or doing a tough field job, these pre-workouts may help you by providing you with the jolt of energy and endurance required for these strenuous physical jobs.

However, a real problem arises when you need to pick one among tons of available products claiming to enhance endurance and energy, and you are unsure which one to choose.

So, in this article, I have compiled a list of 6 top-notch brands with their comprehensive detail that may help you make the right decision while choosing the best pre-workout for endurance.

Does pre-workout boost endurance?

Definitely YES! Pre-workouts do help boost endurance.

Let me explain how.

If you’re looking for pre-workouts specifically for endurance, you should search for a particular combination of ingredients that may help increase endurance.

Certain powerful herbs, enzymes, and amino acids like Citrulline Malate, L-Taurine, Beta-alanine, L-Tyrosine, etc.

These ingredients increase endurance by improving blood flow, minimizing fatigue, and increasing muscle strength. In this way, they may also aid in enhancing focus, energy, and stamina.

Thus, before investing in pre-workouts, especially for endurance, look out for these primary combinations of ingredients that may help you get your desired results.

6 Best Pre-workouts for Endurance

Following is the list of 6 best pre-workouts that can help you with endurance:

  • Crazy NutritionIntensive Pre-train Pre-workout
  • Kaged Muscle Pre-Kaged Sport Pre Workout 
  • Gorilla Mode Pre-workout
  • Shred Rx Pre Workout Powder 
  • Flow Supplements, Natural Pre-Workout Powder
  • Old School Vintage Blast Pre-workout Powder

1. Crazy Nutrition Intensive Pre-train Pre-workout

crazy nutrition pre-workout

Crazy nutrition is manufactured by a UK-based company that takes pride in dominating the supplement business for years.

The company provides high-quality supplements created in FDA-approved facilities and contains only the most effective ingredients based on their well-researched recipe.

Intensive Pre-Train by Crazy nutrition comprises 19 premium ingredients that stimulate natural protein production and significantly boost endurance and performance.

This pre-workout supplement, which is vegan-friendly, is designed not only to strengthen your muscles but promote overall health; in this way, you’ll be able to get the dose of energy and endurance required for any challenging physical activity.

I have included Intensive pre-workout in this list of pre-workouts for endurance because it contains those specific ingredients that may significantly enhance endurance and strength.

Let’s have a look at the mechanism of these power ingredients.

First of all, it includes L-Citrulline Malate. This non-essential amino acid is considered a fatigue-fighting nutrient and stamina booster to gradually increase your endurance and muscle mass through exercise.

To validate my point, this study conducted on healthy cyclists revealed that Citrulline-treated cyclists were able to pedal for 12% longer before exhaustion than those taking a placebo.

Additionally, it has also been shown to boost the oxygen content of muscular tissue, which may improve endurance.

The other key ingredient is KSM-66, which is the chemical name for Ashwagandha Root Extract, the herb renowned for its ability to simultaneously promote endurance and muscular size.

study conducted on 50 healthy male and female adults to determine the efficacy of ashwagandha root extract indicates that it increases cardiorespiratory endurance and improves the quality of life in healthy athletic people.

The other powerful ingredients include L-taurine, Beta-Alanine, Caffeine, and L-Tyrosine.

Intensive pre-train comes in a delectable blue raspberry flavor, and you can get it from their official website at the cost of $39.99 per tub, but you can save some bucks if you choose a subscription.

The company provides free shipping along with a 60-day money-back guarantee.

  • No digestive issues and cramps.
  • Remarkable energy levels.

  • Free shipping.

2. Kaged Muscle Pre-Kaged Sport Pre Workout 

Pre Kaged

The second on my list is the Pre-Kaged Sports pre-workout supplement by Kaged Muscle. The company claims to be an elite supplement brand with ultra-premium and health-focused products that actually work.

Pre-Kaged Sports pre-workout powder is carefully created with critical components that provide the optimal combination of energy, endurance, focus, hydration, and power to boost any kind of physical performance.

This pre-workout supplement lets you push yourself to the limit by featuring potent ingredients such as power Betaine, plant-based Citrulline to improve blood flow, fatigue-fighting Carnosine beta-alanine, and many more.

Beta-Alanine is the ingredient that pushed me to include it in my list of pre-workouts for endurance.

It contains 1.6 grams of Beta-Alanine, non-essential amino acid. It produces Carnosine, which helps minimize the formation of lactic acid in your muscles during exercise, resulting in increased athletic performance.

Moreover, Beta-alanine aids in increasing your time to exhaustion as a study of 20 men on a 2000m rowing test found that taking beta-alanine supplements for four weeks enhanced their time to fatigue by 13–14 percent.

Another primary ingredient is 1.5 g of Creatine HCL, which is one of the most scientifically backed supplements available.

One prospective benefit of creatine is its capacity to enhance training sessions, which may result in long-term improvements in endurance performance.

study was carried out to explore the changes in creatine and creatinine concentrations after lower dosages. It was discovered that daily creatine supplementation had positive effects on short-term training included in aerobic endurance exercise.

Additionally, the supplement has a high concentration of antioxidants, which may improve overall health by combating free radicals that cause oxidative stress in muscles during exercise.

Pre-Kaged pre-workout is third-party tested and comes in seven exotic flavors to choose from.

The price of Pre-Kaged is $39.99 for 20 servings, making it $2 per serving. You can buy it from their official website as well as from Amazon and many other online retailers.

3. Gorilla Mode Pre-workout


Next on my list is Gorilla Mode Pre-workout by gorilla mind is US-based company owned by Mike Cernovich.

Gorilla Mode is a pre-workout supplement that promises to include the highest concentration of all pre-workout components they believe work.

With Gorilla Mode, you may expect a considerable rise in nitric oxide (NO) levels, intramuscular hydration, power, focus, and a significant boost in muscle strength and endurance.

Why I’ve included it in my list of best pre-workouts for endurance? The reason is its power-packed profile of ingredients that help increase endurance and energy, power, and focus.

The main ingredient is 9000mg of pure L-citrulline.

Probably the only pre-workout in the entire supplement industry with the maximum effective dose of PURE L-Citrulline without being artificially inflated with Malic Acid.

L-citrulline is the most effective supplement for increasing blood nitric oxide (NO) levels. According to research, it considerably increases muscle endurance and decreases soreness, allowing you to work harder, longer, and more consistently.

It also contains a hefty dosage of nootropics like L-Tyrosine, Kanna, and Huperzine A.

L-tyrosine has positive effects on the mind but ultimately results in improving energy, focus, and mood.

It has been demonstrated that L-tyrosine increases energy and endurance. It is ideal for all athletes and anyone who exercises on a daily basis.

How? Well, according to this study, individuals who used L-tyrosine supplements in the form of a drink as part of their routine training and exercise regimens experienced an increase in endurance. These test subjects maintained peak performance even in harsh situations such as heat.

Gorilla mode comes in ten delicious flavors, making it simple for everyone to find their favorite.

It is available from their website and Amazon for $49 per tub. Purchasing from their official website ensures that you receive genuine products at a reasonable price.

4. Shred Rx Pre Workout Supplement

According to Shred Rx, no other brand stands behind its products as firmly as they do because they understand and believe in their products’ power.

Shred Rx is an all-natural nitrogen-blend formula developed to boost athletic drive, endurance, strength, and performance in all enthusiasts to another level.

It is a scientifically dosed pre-workout created with a unique blend of top-tier balanced and smooth ingredients.

Shred Rx pre-workout supplement contains a unique combination of nitric oxide with creatine monohydrate to test your strength and endurance limits.

This combination provides balanced and consistent power and muscle growth while reducing muscle fatigue, allowing your muscles to perform at their maximum capacity.

If I talk about Nitric oxide first, it is a vasodilator that improves blood and oxygen flow into the muscles. Wider blood vessels aid in transporting nutrients and oxygen to exercising muscles, hence improving performance.

According to this Shred Rx Pre Workout Supplement’s NO supplementation is likely to produce a positive result when endurance exercise ability is evaluated.

On the other hand, creatine monohydrate is renowned for improving exercise performance.

Here’s how.

study was conducted to determine the effect of creatine supplementation on repeated sprint runs performed by well-trained young male handball players. It was discovered that large doses of creatine supplementation boost the performance of these well-trained players during repeated sprint runs.

5. Flow Supplements – Natural Pre-Workout Powder

flow pre-workout

Flow supplements is a US-based company founded by actor Zachary Levi and Markus Trillsch to create a supplement that actually enhances the flow of your workout, vitality, and life.

Flow Pre was developed to provide you with everything you need to nourish your body during those strenuous workouts, hard cardio days, or other physically demanding activities.

It is clinically dosed pre-workout that promotes vasodilation and aids in transporting nutrients to muscle tissue. This aids in fatigue management as well as muscle fiber regeneration and growth.

Let’s look at their key ingredients, which may help boost endurance and power.

With 5000mg of L-citrulline, it contains 3200 mg of Beta-alanine. Beta-Alanine is a non-essential amino acid that helps in producing Carnosine. It is a chemical that contributes to muscular endurance during periods of high-intensity exercise.

As per this study, CarnoSyn beta-alanine increases muscle endurance and helps prevent weariness during workouts. In this way, it increases your time to exhaustion(TTE).

Another critical ingredient is 200 mg of natural Caffeine anhydrous that can provide you with the dose of focus and energy to perform better in any physical activity.

Caffeine is a commonly used supplement by athletes.

According to this experiment conducted on skilled cyclists, cyclists who ingested 200 mg of Caffeine completed the time trial faster than cyclists who consumed 100 mg of Caffeine.

However, too much dosage of Caffeine can cause jittery, anxious feelings.

Other ingredients include L-taurine, Glycerpump, and green tea extract.

Flow Pre has fully transparent labeling, allowing you to record each ingredient you’re consuming.

It comes in 4 different flavors at $49.99 for 30 servings which is a little expensive.

It can be purchased from their official website as well as from Amazon.

The company also provides a 30-day money-back guarantee and ships globally.

  • Naturally flavored and sweetened.
  • Transparent labeling with correct dosage information.
  • suitable for both men and women.

6. Old School Vintage Blast Pre-workout Powder

vintage blast

Old school Labs is a relatively new US-based brand headquartered in Southern California.

As the name suggests, the mission of Old School Labs is to bring their favorite old-school pastimes to the modern school and contribute to their evolution and development.

Vintage Blast Pre-Workout by Old School Labs is marketed as the world’s first two-stage natural pre-workout supplement for both men and women.

Two-stage suggests that some ingredients are designed to be more slowly digested than others so that your body can produce and transmit energy continuously, allowing you to push through your whole workout.

The ingredients of Old School Labs Vintage Blast are split into two categories: Start Strong and Finish Strong.

Start strong includes 5000mg of L-Citrulline Malate, L-Carnitine Tartrate (250 mg), and Caffeine Anhydrous (150 mg).

Finish strong includes D-Aspartic Acid (2,000 mg), N-Acetyl-L-Tyrosine (250 mg), and Microencapsulated Caffeine (100 mg).

If I analyze ingredients for boosting endurance, the first key ingredient is L- Citrulline, a naturally occurring amino acid.

L-citrulline is a component of nitric oxide, which helps increase blood flow and blood pressure, resulting in improved endurance and athletic performance.

Citrulline malate has been shown to improve aerobic and anaerobic performance during extended endurance exercise. It was done by minimizing weariness, raising nitric oxide levels in the body, improving blood flow to working muscles, increasing work productivity, and possibly increasing muscle ATP levels.

The remaining ingredients are as follows:

  • D-aspartic acid is slightly associated with a transient increase in testosterone.
  • Tyrosine may aid in concentration.
  • L-carnitine tartrate may aid in energy and attention.
  • Beta-alanine has a high association with endurance.

So it has beta-alanine that I’ve discussed above, which may help boost endurance and provide the required dose of energy significant for various strenuous physical pursuits.

The vintage blast comes only in one flavor, which is Blueberry Lemonade. The price of 20 servings tub is $39.99.

The company provides free shipping on all orders above $69.99 and a 100% money-back guarantee if you aren’t satisfied with the product.

You can purchase Vintage Blast from their website and Amazon as well.


  • Naturally sweetened through stevia leaf extract.
  • No artificial flavors.
  • Non-GMO and soy-free.
  • Unique two-stage formula.
  • Optimum ingredient profile for endurance and energy boost.


  • Only one flavor to choose from, and that may be sour for some.
  • Pricier than most of the pre-workouts.
  • Takes time in dissolving.

What to look for in Pre-workout for Endurance?

If you’re on the hunt to purchase pre-workout for endurance, you might feel skeptical about which product to get your hands on among the plethora of supplements available.

Keep in mind that mainly ingredient profile and correct dosage create a difference among the pre-workout supplements.

So before choosing a pre-workout for endurance, look for the ingredients that are critical for boosting endurance.

I’ve made a list of key ingredients you must look for before buying a pre-workout for endurance to make things easier for you. If the supplement lack any of these ingredients, it might not deliver the best results.

These ingredients are:

1. L-Citrulline Malate

L-citrulline is a must-have ingredient for purchasing pre-workouts for endurance. It is a non-essential amino acid that was firstly found in watermelons. It’s a vasodilator and helps improve blood flow.

Citrulline may enhance muscle oxygenation and performance during exercise. Pre-workout supplements with Citrulline can be used to enhance both endurance and strength training performance.

According to the findings of this study, which was done on healthy males for cycling time trial performance, L-citrulline dramatically reduced subjective symptoms of muscular tiredness and concentration immediately after exercise.

Thus, we can say that supplements with Citrulline may significantly boost endurance.

2. Beta-Alanine

Another critical ingredient is Beta-alanine, which has gained widespread recognition as a potent supplement for endurance training and racing.

It improves performance by boosting exercise capacity and minimizing muscular exhaustion. Additionally, it possesses antioxidant, immune-stimulating, and anti-aging qualities.

Supplementing with beta-alanine has tremendous results on endurance and overall health.

A double-blind study conducted to evaluate sprint performance in endurance cycling demonstrated that oral beta-alanine supplementation considerably improves sprint performance after an exhausting endurance exercise bout.

3. Caffeine Anhydrous

Caffeine is one of the most extensively researched products on the market. Studies have linked its use to improved endurance performance as it keeps you focused and energetic for a more extended period.

Recent research indicates that Caffeine may either enhance or impair workout performance.

Explicitly talking about endurance, Caffeine improves endurance significantly when used in moderate levels (3–6 mg per kg) of body weight, according to a significant analysis of this research.

Additionally, due to its beneficial effects o

n exercise performance, specific organizations, including the National Collegiate Athletic Association (NCAA), have begun prohibiting it in excessive dosages.

Final Thoughts

As you can see, all of the pre-workout supplements listed above can have a substantial influence on endurance and strength since they include the necessary elements to achieve your desired outcomes.

They are not only useful for gym purposes but also for any work that involves rigorous physical training/exertion.

With a complete description of all the ingredients and their associated benefits and drawbacks, it’d be much easier for you to make an informed decision.

Additionally, before purchasing an endurance supplement, you should check for the elements mentioned above to achieve optimal results.

To conclude, I would like to emphasize that if you have a pre-existing medical issue, it is always prudent to consult your physician prior to taking a pre-workout supplement.
