Can Pre-Workout Supplements Cause High Blood Pressure?

If you’re someone who takes pre-workout supplements, you might be wondering if they can cause high blood pressure. While there’s no definitive answer, there are some things to consider if you’re worried about this potential side effect. Read on to learn more.


Pre-workout supplements have become increasingly popular among athletes and active individuals. Unfortunately, many of these products contain highly-refined ingredients that can have a negative impact on your health, including raising your blood pressure. This article will explore the potential connection between pre-workout supplements and high blood pressure, as well as possible alternatives to using these types of products.

It is important to note that pre-workout supplements are not regulated by the FDA and may contain potentially harmful ingredients. As such, it is important to research any product thoroughly before taking it and to speak with your doctor about any side effects you may experience. By understanding how pre-workout supplements can affect your body and exploring safer options for boosting your exercise performance, you can make responsible decisions about what kind of supplementation regimen is best for you.

What are Pre-Workout Supplements?

Pre-workout supplements are nutritional supplements that are consumed before a workout to improve performance. It typically contains a combination of ingredients such as caffeine, creatine, beta-alanine, amino acids and other energy-boosting compounds.

The purpose of these supplements is to help the body stay focused during workouts while providing necessary energy boost to help push through strenuous exercise. Although these supplements have been shown to be beneficial in increasing workout performance, there is also some potential risk associated with them including high blood pressure.

Therefore, it is important for those considering taking pre-workout supplement to understand what’s in it and its potential side effects before consuming them. Consultation with a healthcare professional should also be sought if you have any underlying health concerns like hypertension or cardiovascular disease.

Types of Pre-Workout Supplements

Pre-workout supplements are designed to give you that extra boost of energy in your workouts, helping you to stay energized and motivated throughout. These are comprised of a range of ingredients, including caffeine, amino acids, vitamins, minerals and other herbal extracts with reported ergogenic effects. While the exact composition of pre-workout supplements may vary from brand to brand, some common ingredients include:

– Caffeine: Caffeine can improve performance for certain activities. It may also help reduce fatigue and muscular pain during exercise sessions.
– Beta-Alanine: This amino acid is thought to increase muscle carnosine concentrations which can help improve performance output in certain activities.
– Arginine: This amino acid is thought to help dilate blood vessels which could bring more oxygenated blood flow to the muscles for improved performance.
– Citrulline Malate: Citrulline malate is believed to reduce fatigue during exercise while increasing endurance and time trial results.
– B Vitamins: The B vitamins help support your metabolic pathways involved with energy production and performance output during intense physical activity.

Overall, pre-workout supplements have the potential to increase both performance and focus if chosen safely by an informed consumer; however, they can also be dangerous if taken largely in excess or without being aware of potential side effects such as increasing blood pressure levels. Therefore it is important that users proceed with caution when looking into these types of compounds and ensure that they are using them responsibly at all times for maximum benefit without any unwanted risks associated with regular use or overdose.

Potential Side Effects of Pre-Workout Supplements

Pre-workout supplements can be an effective way to improve your performance in the gym and boost your energy levels. But like any supplement, there are potential side effects to consider. One possible side effect of taking pre-workout supplements is increased blood pressure. In this article, we will look at the current research on pre-workout supplements and their effect on blood pressure.

High Blood Pressure

Pre-workout supplements are dietary supplements used to increase energy, endurance, and focus before exercise. While they may benefit athletes and those interested in maximizing their workouts, these products come with potential side effects that can be very serious. High blood pressure, or hypertension, is one of the most common side effects associated with pre-workout supplements.

Hypertension is defined as having consistent systolic readings (the top number) higher than 120 mm/Hg (millimeters of mercury) and/or diastolic readings (the bottom number) higher than 80 mm/Hg. When your blood pressure runs high for a long period of time it can cause damage to multiple parts of your body including your heart, brain, kidneys, and eyes. The powerful ingredients found in pre-workout supplements often raise the user’s blood pressure due to their stimulant effects on the body. Common ingredients associated with an increase in blood pressure include caffeine and guarana, which is a naturally occurring source of caffeine extracted from plants. High doses of caffeine have been linked to raising both systolic and diastolic blood pressure levels when consumed regularly over time.

Other ingredients found in pre-workout supplements that could cause an increase in blood pressure include synephrine (bitter orange extract), yohimbe extract, green tea extract, vitamin B6 and niacin (a B vitamin). It’s important to keep monitor your heart rate during exercise taking into consideration any potential medications you are taking as well as pre-workout supplement usage before engaging in physical activity or exercise. It’s also recommended that athletes consult a doctor prior starting or changing dosages for any supplement regimen especially when there is the risk for elevated blood pressure associated with high intensity activities like those seen during exercises and sports performances where pre workout supplements are taken.


Dehydration is a common side effect of pre-workout supplements, especially when taken in heavy doses or in lieu of water to stay hydrated. The body needs an adequate amount of fluid to stay healthy and to perform optimally during physical activity. Without proper hydration, symptoms such as headache, dizziness, fatigue and excessive thirst may occur. As a result, it is important that individuals taking pre-workout supplements drink the recommended 8–10 glasses of water per day and replenish any fluids lost through perspiration during exercise or other physical activity. Additionally, it is essential that individuals check with their healthcare provider before starting a new pre-workout supplement regimen as these supplements can interact with certain medications and other substances in the body.


Nausea is among the most common potential side effects of consuming pre-workout supplements due to the high level of caffeine they usually contain. While pre-workout supplements can give you an extra boost of energy before your workout, it’s important to be aware that too much caffeine can cause nausea and other digestive issues. Other ingredients such as creatine and beta-alanine may also cause nausea, especially if taken on an empty stomach or with insufficient water or liquid.
It’s important to read all product labels carefully and check for hidden sources of caffeine and other stimulants like guarana or yerba mate. If you experience indigestion, upset stomach or any other adverse reaction after taking a pre-workout supplement, it’s best to lower the dosage or discontinue use altogether in case you are more sensitive than usual. It is also recommended that you drink plenty of fluids while taking pre-workouts to avoid dehydration and overall feelings of sickness.


Headaches are a common side effect of taking pre-workout supplements. This is usually caused by the presence of ingredients like caffeine and other stimulants, which can cause blood vessels in the head to constrict, leading to headaches. Additionally, a lack of hydration can also cause headaches when using pre-workout supplements. To reduce your chances of getting a headache, it is recommended that you drink plenty of water before and throughout your workout. You should also consult with your doctor or pharmacist regarding any potential side effects or interactions between pre-workout supplements and medications you may currently be prescribed. If headaches persist after drinking adequate amounts of water, then it may be wise to abstain from taking pre-workout supplements altogether or at least reduce the recommended dosage.

Risk Factors for High Blood Pressure

High blood pressure, or hypertension, is a serious health issue and can be caused by a variety of factors. One factor that can contribute to high blood pressure is pre-workout supplements. Many of these supplements contain stimulants that can increase your heart rate and blood pressure. In this article, we will discuss the risk factors for high blood pressure and how pre-workout supplements can play a role in it.


Obesity is one of the most significant risk factors for high blood pressure. Being overweight increases the work your heart and lungs have to do in order to keep your body going. It also causes your body to produce hormones that increase blood pressure. Maintaining an appropriate weight is a key part of managing, and possibly preventing, high blood pressure. Weight loss can even help reduce the need for certain medications used to treat hypertension. Furthermore, there is no evidence that pre-workout supplements cause or contribute to obesity or related high blood pressure issues when consumed in moderation as recommended by a physician.


Age is one of the most important risk factors associated with high blood pressure. The risk increases significantly as we age, especially after age 45. As people get older, their arteries generally become less elastic and stiffer, making it more difficult for the heart to pump through them efficiently. The inner walls of their arteries also become thicker due to fat deposits and calcium buildup; this further restricts blood flow. This accumulation of fat and calcium may be exacerbated by lifestyle choices such as smoking and poor diets that are high in saturated fat, trans fats, cholesterol and salt. One other important factor to keep in mind is that the blood vessels of older adults do not respond quickly or efficiently when needed to regulate their blood pressure, causing an increased risk for dangerous spikes in pressure.


An individual’s genetic background can play a role in the development of high blood pressure. This means that if you have a parent or grandparent who suffered from hypertension, then you may be more at risk for developing high blood pressure yourself. It is important to know your family medical history and talk to your doctor about any possible predispositions you may have for developing hypertension. Additionally, lifestyle modifications such as exercising regularly and maintaining a healthy weight can help reduce your risk of having high blood pressure due to heredity.


Stress is an important risk factor in the development of high blood pressure. Our bodies respond to triggers by releasing adrenal hormones which cause our hearts to beat faster and raise our blood pressure. When we feel stressed, our bodies stay in a “fight or flight” mode – this means that the normal processes that keep us calm and relaxed are thrown out the window in favor of a fast response time. Over time, continuous exposure to high levels of stress can lead to chronically elevated blood pressure.

In addition to mental and emotional stress from work, school, family life or relationships, physical stress from strenuous exercise or poor sleep habits also increase your risk of developing hypertension. That said, it’s important also to consider if any pre-workout supplements contribute additional ‘stress’ on the body and if these pre-workouts affect anyone’s symptoms or overall health when it comes to high blood pressure management. If someone already has a history of high blood pressure, they should consult their doctor before starting a pre-workout supplement routine as many supplements contain significant amounts of stimulants which may exacerbate high blood pressures symptoms.

Precautions to Take

When using pre-workout supplements, there are several precautions that should be taken in order to avoid potential side effects. Although pre-workout supplements often contain beneficial ingredients such as B vitamins and caffeine, these substances can lead to dangerous health consequences if not used properly. Notably, pre-workout supplements can cause a rise in blood pressure if taken excessively or combined with other stimulants.

Before using any pre-workout supplement, it is important to consult your healthcare provider about possible contraindications. They can help run tests to determine your baseline blood pressure and advise you on the best dosage for your individual needs and health history. It is also important to read the label carefully and pay attention to the ingredients, as certain additives or dosages, especially those containing high levels of caffeine, may increase blood pressure further. Additionally, certain medications can interact with pre-workout supplements and cause an elevation in blood pressure; always check with your doctor before combining medications or supplements.


The evidence to date shows that there is no clear link between the use of pre-workout supplements and high blood pressure. However, this does not mean that it is safe to take pre-workout supplements without caution. Some individuals may experience side effects such as nausea, headaches, fatigue, and increase heart rate, which could be a sign that their bodies are responding negatively to the ingredients in pre-workout supplements. Therefore, it is important to take precaution when taking pre-workout supplements by monitoring your own responses and being aware of potential side effects. Additionally, if you do suffer from high blood pressure or any other cardiovascular condition, it is best to avoid taking pre-workout supplements altogether or consult a medical professional before doing so.
