Does Pre-Workout Make You Sweat More? Maybe. (Here’s Why)

pre-workout supplements

You’re not alone if you seem to sweat buckets during a workout after using a pre-workout supplement.

You may have heard that caffeine in pre-workout can induce sweating, but pre-workout brands contain other common ingredients with thermogenic properties that raise body temperature and lead you to sweat more. 

Another seemingly obvious factor to consider is that pre-workout enhances performance, so many find themselves training harder and longer when they use a pre-workout supplement.

That alone could have a lot to do with the increased perspiration. 

Pre-workout can help you take your fitness to the next level, but it has side effects.

In this article, we’ll discuss the impact of pre-workout on your exercise routine and answer the question, does pre-workout make you sweat more?

Short Summary

  • Pre-workout supplements can boost your workout intensity, making you more likely to break a sweat.
  • Caffeine and pepper extracts can cause increased sweating
  • Beta-alanine, cayenne, green tea extract, yohimbe, and garcinia cambogia are thermogenic ingredients commonly found in pre-workouts that increase body temperature
  • Stay hydrated, choose the right supplement, and adjust your environment to manage excessive sweating while maximizing performance!

The Connection Between Pre-Workout and Sweating

After taking pre-workout supplements, you may have noticed a bit more sweat during gym sessions. This isn’t by chance. The ingredients in these products can boost your heart rate, core body temperature, and workout intensity.

Pre-workout supplements can augment workout intensity and stimulate sweating through ingredients like caffeine, beta-alanine, and pepper extracts. However, adequate hydration, a suitable supplement, and a well-adjusted environment are crucial for managing excessive sweating and maximizing performance.

Nevertheless, this doesn’t always signify pushing yourself harder. Rather, it’s due to how the stimulant and thermogenic properties affect your body when using pre-workout items. 

Pre-Workout Ingredients That Affect Sweating

Some ingredients in pre-workout supplements can indeed increase sweating by elevating your heart rate and core body temperature. This is primarily due to their stimulant and thermogenic properties. 

Stimulants like caffeine enhance sweat production by boosting metabolism and heart rate. Though not all stimulants have thermogenic properties, caffeine does. Thermogenic ingredients further amplify this effect by acting as internal heaters and improving fat-burning capacity. 

In addition to these, components such as nitric oxide boosters can also heighten sweat production. Nitric oxide supplements can benefit athletic performance because they open up the blood vessels, which leads to better blood flow throughout the body (and muscles).


Regarding pre-workouts, caffeine is a key ingredient that can also significantly increase sweat production. It causes your heart rate and metabolic rate to rise and raises your body temperature.

Caffeine’s job is to increase nervous system activity, which also increases sweat gland activity. It’s like a natural accelerator leading you to push harder. If not taken properly, having too much caffeine may have adverse effects like nervousness, tremors, or excessive perspiration. 

Green tea and green tea extract help your body burn fat and use energy because of two key ingredients: caffeine and substances called catechins. Caffeine boosts energy levels, while catechins slow down the process that usually makes your body use less energy, making it use more instead. Both work together to help your body burn fat. 


Thermogenic compounds act as inner heaters of the body that increase fat-burning capacity when combined with a sound workout program. Thermogenic ingredients in pre-workout can raise your body temperature. What comes with increased body temp? Sweat.  

Since sweat is proportional to metabolic rate, it makes sense to assume that these ingredients that increase metabolism may also increase someone’s propensity to sweat. For example, natural compounds like Garcinia Cambogia and Yohimbe derived from plants are often used in dietary supplements to increase metabolic rate. 

Pepper Extracts 

Pre-workout supplements often contain extracts from certain types of peppers known for their thermogenic or metabolism-boosting effects. Here are a few common ones:

  1. Capsaicin: This is the active component of chili peppers (Capsicum sp.) and gives them their characteristic heat. Capsaicin increases thermogenesis (heat production) and stimulates fat burning.
  1. Capsiate: This is a non-spicy compound derived from a variety of sweet pepper with similar effects to capsaicin. It is used because it provides the thermogenic benefits of capsaicin without the spicy burning sensation.
  1. Piperine: This compound is found in black pepper (Piper nigrum) and is known for its ability to increase the absorption of other nutrients, which can enhance the overall effectiveness of a supplement. Biopirene® is a common black pepper extract found in pre-workout. 

Nitric Oxide Boosters

When nitric oxide (NO) levels increase, blood vessels relax and widen in a process known as vasodilation. This results in increased blood flow throughout the body, including to the skin’s surface.

With exercise, your body’s core temperature rises, and your body tries to cool itself down by increasing blood flow to the skin, where heat can be released. This mechanism involves the production of sweat. As the sweat evaporates, it helps to cool the body down.

Sweating is a potential side effect of nitric oxide. If nitric oxide levels are high it causes vasodilation and enhanced blood flow. This could potentially lead to increased sweat production as the body works to cool down due to the enhanced blood flow to the skin surface.


Beta-alanine is included in pre-workout supplements because it helps produce carnosine, a molecule that helps buffer acid in muscles during high-intensity exercise. This can delay muscle fatigue, improve endurance, and enhance performance in workouts, especially those involving short, intense bursts of effort.

How to Manage Excessive Sweating From Pre-Workout Intake

Staying hydrated is essential to mitigate excessive sweating. Since water acts like a natural coolant within the body, it helps your body temperature remain balanced and minimizes perspiration. 

Additionally, when we sweat profusely, we lose fluids, so it’s essential to replace this liquid to keep everything functioning effectively. Drinking water before, during, and after physical activity keeps you invigorated and hydrated during and after exercise. 

Choosing the Right Pre-Workout Supplement

When selecting a pre-workout supplement, choosing one with natural ingredients and fewer stimulants may help reduce excessive sweating. Transparent Labs is one brand that offers stimulant-free options for those who wish to minimize their perspiration while still benefiting from an energy boost.

Stim-free pre-workouts contain the same ingredients, just without the stimulants. Obviously, some sweat-inducing ingredients will still be present, but removing stimulants will likely make a significant difference in how much you sweat from the supplement. Look for ones with less pepper extracts and less caffeine, or caffeine-free. 

The Impact of Individual Factors on Sweating and Pre-Workout Use

Sweating during workouts can vary based on individual factors like genetic predisposition, fitness level, and age. Some people naturally sweat more, which pre-workout supplements can augment. 

Genetic Predisposition

Genetics can significantly influence how much and how quickly an individual sweats. Some people just have a higher number of sweat glands due to genetic factors.

Genetic conditions like hyperhidrosis, which causes excessive sweating, can be passed down through families. Therefore, if your parents or close relatives tend to sweat a lot, there’s a chance you might experience the same due to your genetic predisposition.

Fitness Level

People with higher fitness levels often start sweating sooner and more profusely during exercise. This is because their bodies have become more efficient at cooling down to prevent overheating.

The body adapts to regular, intense exercise by enhancing its sweat response. As a result, fit individuals may start to sweat at a lower body temperature compared to those less fit. This increased sweating aids in keeping body temperature regulated during exercise. The human bodproduces sweat to avoid overheating.


Age can affect sweating due to changes in the body’s ability to regulate temperature. As people age, their sweat glands may become less active, leading to decreased sweating. Certain medical conditions more common in older age, like diabetes or thyroid problems, can also affect sweat production. 

Can Pre-Workout Cause Overheating?

Pre-workout supplements will not lead to an excessive heat overload. Substances like stimulants and thermogenic elements heighten body temperature while exercising, making it feel similar to setting the thermostat a notch higher.

As long as you remain hydrated and are conscious of your body’s needs during exercise, there’s no need for concern about overheating due to pre-workout supplementation. So even if your internal temperature might climb slightly when using these kinds of products, with proper precautions taken, you can keep this increase minimal so that it does not become problematic in any way.

SummaryDoes Pre-Workout Make You Sweat More?

Pre-workout supplements can lead to increased sweating due to the thermogenic ingredients they contain, such as caffeine and pepper extracts. These ingredients can raise body temperature and intensify workouts, increasing perspiration. They work by boosting metabolism, heart rate, and fat-burning capacity, with some also increasing blood flow to the skin’s surface to aid in cooling the body.

However, individual factors such as genetics, fitness level, and age can also affect how much a person sweats. Despite this, pre-workout supplements won’t cause excessive overheating if appropriately used. Staying hydrated and choosing supplements with fewer stimulants is essential if excessive sweating is an issue.

These products can help take fitness to the next level but come with side effects, and users should be aware of how the stimulant and thermogenic properties of pre-workout items affect their bodies.

Discuss any particular supplement with your doctor or a licensed practitioner before starting a new supplement regimen if you take medication or have pre-existing health conditions. If you want to know more or have concerns about introducing a pre-workout into your fitness routine, consider seeking advice from a health and fitness professional at EverFlex. 

Frequently Asked Questions

Are there side effects to pre-workout?

Before taking pre-workout supplements, one should be aware of their potential risks. These could include increased heart rate, dehydration, jitters, anxiety, insomnia, stomach irritation, and nausea.

It is important to take caution when consuming these types of products to protect your health. Pre-workout can drastically impact an individual’s physical condition if not used properly. 

Does pre-workout make your sweat smell?

For a workout with no sweat, pre-workout supplements not containing betaine may be the answer since these products have been linked to increased body odor. Consider switching your current pre-workout supplement if you want to avoid this kind of consequence.

Does creatine make you sweat?

Exercising while taking creatine has been reported to increase sweat levels, yet the supplement does not directly result in perspiration. Studies show that using it as a topical application could potentially diminish wrinkles and other signs of aging or skin damage.

Does more sweating mean a better workout?

Exercise intensity can’t be determined merely by the amount of sweat generated. Sweating is simply a natural response to help control body temperature. Don’t over-rely on it as an indicator of how intense your workout may or may not be.

Can pre-workout cause overheating?

Pre-workout supplements can increase your body temperature while exercising because of the stimulants and thermogenic elements, which could cause overheating. This is an important health risk to be aware of, so it’s necessary to understand all potential risks associated with taking these kinds of supplements to prevent yourself from getting too hot during exercise. Pre-workouts are powerful tools if used responsibly. Doing so, you’ll reap their benefits without putting yourself in unnecessary danger.
