Why Do Pre-Workout Drinks Make You Tingle?

You may have noticed that some pre-workout drinks make your skin tingle. Learn why this happens and if it’s something you should worry about.


Pre-workout or energizing drinks are designed to give you an extra boost of energy while exercising. But why do they sometimes make your skin tingle? In this article, we will explore the science behind why some pre-workout drinks can cause a tingling sensation on your skin.

Many popular pre-workout drinks contain ingredients such as caffeine, B vitamins, and other stimulants that can increase alertness and help your body to better utilize fat for energy. Stimulants such as caffeine can act on the central nervous system (CNS) causing changes in blood flow and metabolism of cells, resulting in a “rush” that is often associated with the consumption of these drinks. This rush can result in a tingling feeling in your extremities due to increased nerve activity from the CNS.

In addition, some pre-workout formulas might contain niacin (often referred to as Vitamin B3), which activates certain receptors located near nerve endings. When these receptors are activated, nerve signals are sent throughout the body and can result in a tingling feeling known as “niacin flush” or “niacin rush” that is commonly seen after consuming pre-workouts containing niacin. Niacin flush usually subsides within an hour but may be more unpredictable depending on how much pre-workout was consumed.

What is Pre-Workout?

Pre-workout drinks are often used by athletes, bodybuilders and gym goers to help them get energised and focused to perform their best at competition or during workouts. These drinks usually contain some combination of caffeine, BCAA’s, arginine and other ingredients that, when combined, can help to increase performance and reduce fatigue. But why does it make you tingle? Let’s take a look.

Types of Pre-Workout Supplements

Pre-workout supplements come in many forms, depending on your activity. While it’s important to choose the right one for your specific needs, some of the most common types of pre-workout supplements include:

-Nitric Oxide Boosters: These supplements increase blood flow and can provide a boost in energy. Nitric oxide also helps to reduce fatigue and enhance strength capabilities.
-Caffeine Sources: Caffeine is a stimulant and can help to reduce mental fatigue and improve performance during exercise. It is often combined with other ingredients such as B vitamins or amino acids for additional benefits.
-Creatine Supplements: Creatine is used to enhance muscle power and help muscles recover from exercise more quickly.
-Protein Powders: Protein powders are a popular choice for pre-workouts because they deliver essential proteins that support muscle health and growth, leading to increased strength and improved performance during exercise.
-BCAAs: Branched Chain Amino Acids (BCAAs) are essential amino acids needed to provide energy for muscles during workouts, prevent breakdown of muscle tissue during recovery, and increase endurance levels.
-Beta Alanine Supplements: Beta Alanine can be found in many pre-workouts because it helps reduce fatigue and improve muscular endurance, allowing you to push yourself further while exercising.

What Causes the Tingling Sensation?

Pre-workout drinks are often used by athletes and bodybuilders to give them energy and boost their performance in the gym. But one of the side effects of these drinks is a tingling sensation that users experience after drinking them. While this sensation can be strange, it is perfectly normal and harmless. So, what causes this tingling sensation after drinking pre-workout drinks? Let’s look into this further.


One of the main reasons for the tingling sensation after drinking pre-workout supplements is beta-alanine. Beta-alanine is an amino acid synthesized from the amino acid alanine, and it blocks the cell from using too much energy too quickly. Your body produces this amino acid naturally, and you can also find it in foods like chicken, beef, and pork.

When beta-alanine enters the bloodstream, it gets broken down into its smaller parts – carnosine and histidine – which are both important for optimal muscle performance during exercise. This reaction causes a feeling of itchiness or “pins and needles” known as paresthesia. Other key ingredients found in pre-workout drinks can also cause a similar sensation. These ingredients include caffeine, citrulline malate, glycerol monostearate, creatine monohydrate, arginine alpha-ketoglutarate (AAKG) and beta-hydroxybutyrate (BHB).

It’s important to be aware of these sensations if you’re looking to take pre-workout supplements to increase your exercise performance – though generally they are nothing to worry about! By understanding what causes this tingling feeling and how it signals improved workout performance, you may find that taking pre-workouts helps give you an extra edge in your workouts.


Caffeine is the most commonly used stimulant in pre-workouts and is the primary ingredient responsible for causing the tingling sensation. Caffeine stimulates activity in both the central nervous system and muscles — increasing alertness, focus, intensity, and power. Caffeine also has the potential to narrow your blood vessels, leading to enhanced muscle pumps during exercise. This tingling sensation can be felt when caffeine hits your bloodstream, particularly when consumed on an empty stomach.

Aside from caffeine, other popular ingredients found in pre-workout supplements that can lead to a similar tingling sensation include niacin (also known as vitamin B3) and beta-alanine. Niacin works by dilating blood vessels to encourage good circulation throughout your body while beta-alanine helps buffer lactic acid build-up which can reduce fatigue during workout sessions. It is important to be aware of any possible side effects of pre-workout drinks before consuming them; if you experience any burning or itching that increases after drinking a pre-workout drink, discontinue use immediately and consult your doctor.


Creatine is one of the most popular ingredients in pre-workout drinks for its proven performance-enhancing capabilities. It is naturally found in the body and helps to improve strength and power. However, creatine can also cause a tingling sensation when it is consumed in large doses.

Creatine works to pull water into muscles, which can then lead to paresthesia—a temporary nerve disorder that causes numbness, a prickling sensation or pins and needles all over the body. This feeling can range from mildly irritating to quite intense, depending on how sensitive you are to the ingredient. Fortunately, it usually doesn’t last more than a few minutes after you consume your pre-workout drink.

In addition to creatine like beta-alanine or citrulline malate, some stimulants found in pre-workouts such as caffeine or synephrine can also cause tingling sensations when taken in high doses or with other stimulants like guarana or yerba mate. These types of effects are generally milder than with creatine but can still be uncomfortable for some people. It’s important to pay attention to the ingredients list when selecting a pre-workout drink and make sure not to take too much at once if you’re sensitive to stimulants.


Niacin, also known as Vitamin B3, is a common activity-enhancing ingredient found in pre-workout supplements. It plays an important role in energy production, providing the cells with the energy needed for sustained physical activity. Niacin also helps to support healthy heart and circulatory health, and muscle movement.

Niacin has a unique property called “flushability”. As it is metabolized by the body, it causes your blood vessels and capillaries to dilate resulting in a rush of blood to your skin’s surface. This leads to a sensation similar to pins-and-needles tingling on your skin or a light flushing throughout the body. The intensity of this effect can vary from person to person depending on genetics and other factors such as age and gender.

While this sensation is harmless – even potentially beneficial – some athletes smooth out the peaks of their workouts by taking smaller doses of niacin before they begin their routine or take it in conjunction with other ingredients such as amino acids that have calming effects. Ultimately, pre-workout drinks containing niacin can be great tools for helping athletes maximize their performance during strenuous exercise; but if you experience an uncomfortable level of tingles or flushes, you may want to reduce the dosage or try another medium of supplementation instead.

The Pros and Cons of Pre-Workout Supplements

Pre-workout supplements are a type of dietary supplement that is added to a sports drink or other beverage intended to give the athlete an extra boost of energy before exercise. The most common ingredient in pre-workout supplements is caffeine, but other ingredients like creatine and beta-alanine can also be found in different combinations and concentrations.

The goal of taking pre-workout drinks is to increase physical performance, which can be beneficial for athletes or regular gym goers alike. In addition, the stimulants contained in pre-workout drinks may cause users to feel a tingling sensation during and after consumption. This tingling feeling is described as “pins and needles”, but can also feel like itching or stinging.

The primary benefit of using pre-workout drinks is increased energy levels and improved performance, as well as enhanced alertness along with improved motivation during exercise. The tingling sensation caused by pre-workouts can also lead to improved mental focus which can help users push themselves further while working out.

While there are many advantages to taking pre-workouts, it’s important to note that there may be some risks involved with their use as well. As with any dietary supplement, it’s important for consumers to read the label carefully and be aware of any potential side effects that may occur before use. Pre-workouts may contain high levels of caffeine and other stimulants that could affect heart rate, blood pressure and other bodily functions if taken in high doses or too frequently over a long period of time. Therefore it’s important for consumers to read labels carefully and take the recommended dose as directed by their physician before consuming any type of supplement.

Safety Tips for Taking Pre-Workout Supplements

Pre-workout supplements are designed to enhance your exercise routine and increase physical performance. While these supplements can provide a variety of benefits, taking them without understanding their active ingredients and potential side effects can be dangerous. To use pre-workout safely, it is important to read the ingredient label and follow the specific instructions from the manufacturer.

When using pre-workout supplements, it is important to be aware of any potential signs that may indicate an adverse reaction. For some people, common reactions to pre-workouts include feelings of dizziness, nausea and tingling sensations in the skin – particularly around the face region. Such reactions are generally mild and do not pose a serious health risk, however always consult a medical professional if you feel unwell after exercising with these kinds of drinks or supplements.

In addition to reading labels and paying close attention to instructions on product packaging, it is wise to keep an eye on other medications you may be taking while using pre-workouts. Some prescription drugs can interact adversely with active ingredients; if you experience strong or unpleasant side effects from taking a pre-workout supplement it could be because you are combining multiple products with conflicting active ingredients. It’s best practice to keep all supplements separate when taking them for maximum safety and best results.

Pre-Workouts also contain caffeine as one of the main ingredients in almost all products; those prone to insomnia should limit consumption close to bedtime since caffeine can interfere with restful sleep patterns in those already prone to insomnia or disrupted sleep in general. Be aware that some sources claim that over consumption of such products can have long term negative effects on health so it’s always important that dosage is kept within reasonable limits as advised by manufacturers which notice different should always be heeded also before undertaking strenuous physical activity or exercise sessions which could affect your overall performance at that particular given time thanks for especially allowing your heart rate raised correspondingly elevation pressure levels within blood vessels amongst other physiological systems respectively so too does accordingly require precautionary measure prior such acts involved


In conclusion, the tingling sensation that is experienced when drinking a pre-workout supplement is likely caused by a combination of its active ingredients. In particular, the caffeine and stimulants can cause a heightened sensitivity to touch and pressure in the skin. Additionally, Beta Alanine and Citrulline Malate can cause a distinct tingly feeling known as paraesthesia.

Due to individual reactions to ingredients, it may be necessary to adjust your dosage to find the right combination for you. While many people enjoy this phenomenon as part of their pre-workout routine, it is worth noting that too much of these supplements can cause an uncomfortable feeling. Experimenting with different dosages will help you find the most comfortable level for your body when taking pre-workout drinks.
