Does Pre-Workout Cause Erectile Dysfunction?

Updated July 29, 2023

Pre-workout supplements are popular for enhancing performance, increasing energy, and improving focus during workouts.

However, recent research suggests these supplements may impact sexual health, specifically erectile function.

Pre-Workout Supplements And Their Ingredients

Pre-workout supplements often contain ingredients designed to boost energy and improve workout performance.

These typically include caffeine, creatine, beta-alanine, and various amino acids.

While these ingredients can temporarily boost energy and focus, they can also have side effects, mainly when consumed in large amounts or over a long period.

For instance, excessive caffeine intake can lead to increased heart rate, insomnia, and digestive issues.

The Link Between Pre-Workout Supplements And Erectile Dysfunction

Erectile dysfunction (ED) commonly affects many men, particularly those over 40.

It is characterized by difficulty getting or maintaining an erection sufficient for sexual activity.

ED can be caused by various factors, including physical conditions like heart disease, diabetes, and obesity, as well as psychological issues such as stress, anxiety, and depression.

Recent studies have suggested a potential link between the use of pre-workout supplements and the development of ED.

One study found that the use of dietary supplements, including pre-workout supplements, was associated with an increased likelihood of ED.

The researchers suggested that this might be due to the high levels of caffeine and other stimulants found in these supplements, which can cause vasoconstriction (narrowing of the blood vessels), thereby reducing blood flow to the penis and leading to difficulties in achieving an erection.

The Role Of Heart Health In Erectile Function

Erectile function is closely tied to heart health.

The penis requires a healthy blood flow to achieve and maintain an erection, and any condition that impairs this blood flow can potentially lead to ED.

Conditions such as heart disease, high cholesterol, and high blood pressure are all known risk factors for ED.

Pre-workout supplements, particularly those high in stimulants like caffeine, can increase heart rate and blood pressure, potentially exacerbating these conditions and increasing the risk of ED.

This is particularly concerning given that many users of pre-workout supplements are young men who may not be aware of their underlying heart conditions.

The Underlying Causes Of Erectile Dysfunction In Pre-Workouts

Erectile dysfunction (ED) is a complex issue with many potential causes.

When it comes to pre-workout supplements, several factors could contribute to the development of ED.

The Role Of Stimulants

One of the main culprits is the high concentration of stimulants found in many pre-workout supplements.

These stimulants, such as caffeine, DMAA, and others, are designed to increase energy and focus during workouts.

However, they can also significantly impact the body's cardiovascular system.

Stimulants work by triggering the release of adrenaline, increasing heart rate and blood pressure.

This can constrict blood vessels, reducing blood flow to various body parts, including the penis.

Reduced blood flow is a common cause of ED, as an erection requires sufficient blood supply to the penile tissues.

This is supported by research that shows the impact of stimulants on cardiovascular health.

Moreover, stimulants can disrupt the body's natural hormone production and neurochemistry.

This can lead to mood swings, anxiety, and jitteriness, further exacerbating erectile dysfunction.

Studies have shown the potential impact of stimulants on mood and mental health.

The Impact Of Certain Medications

It's also worth noting that certain medications can contribute to ED.

For instance, some drugs used to treat high blood pressure, depression, anxiety, and other conditions can interfere with the body's ability to achieve or maintain an erection.

While these medications are not typically found in pre-workout supplements, they can interact with the ingredients in these products.

Therefore, if you're taking any medication, it's crucial to consult with a healthcare professional before starting any new supplement regimen.

This is backed by WebMD's comprehensive list of drugs that may cause erectile dysfunction.

The Effect Of Recreational And Frequently Abused Drugs

Recreational and frequently abused drugs, such as alcohol, amphetamines, barbiturates, cocaine, marijuana, methadone, nicotine, and opiates, can also cause ED.

These substances can affect the central nervous system and cause serious damage to the blood vessels, leading to permanent ED.

While these substances are not typically associated with pre-workout supplements, their use can exacerbate any potential ED-inducing effects of the supplements.

This is supported by WebMD's list of substances that can cause or lead to ED.

The Solution

The solution to this issue is rather straightforward — consider cutting out hardcore stimulants, or at least use them sparingly.

Instead of using a pre-workout supplement with numerous untested stimulants, try one with only caffeine as its energy booster. Caffeine is well-studied and has proven safe when used within reason.

This is supported by research on the effects of caffeine on exercise performance.

If you want to be extra cautious, choose the stim-free pre-workout route.

Stim-free pre-workouts avoid any stimulants, including caffeine, and often include natural blood flow-enhancing supplements such as Citrulline Malate.

These supplements boost nitric oxide, dilate blood vessels, and improve blood flow to all body regions.

This is supported by a study that shows the benefits of Citrulline Malate on athletic performance.

Nitric Oxide Boosters And Erectile Function

Nitric oxide (NO) is a molecule that plays a crucial role in many bodily functions, including regulating blood flow.

It acts as a vasodilator, which relaxes and widens your blood vessels, allowing for increased blood flow.

This is particularly important for erectile function, as achieving and maintaining an erection requires sufficient blood supply to the penile tissues.

There are several supplements known as nitric oxide boosters that can help enhance your body's NO production.

These include:

  • Agmatine: Agmatine is a metabolite of the amino acid arginine, known for its ability to boost nitric oxide levels. This can lead to improved blood flow, which benefits both workout performance and erectile function. You can learn more about the benefits of agmatine in this comprehensive guide.
  • Citrulline: Citrulline is another amino acid that can increase nitric oxide production. It's often used in pre-workout supplements to enhance muscle pump and improve workout performance. But its benefits aren't limited to the gym - the increased blood flow it promotes can also help improve erectile function. There's an ongoing debate about the effectiveness of citrulline versus citrulline malate, which you can read about here.
  • Nitrates: Nitrates are compounds found in certain foods like beetroot and spinach. They can be converted into nitric oxide in your body, leading to improved blood flow and potentially better erectile function. Several nitrate supplements, including S7 and 3D Pump, are designed to enhance muscle pump during workouts but could also benefit erectile function.
  • Nitrosigine: Nitrosigine is a patented complex of arginine and silicon that has been shown to significantly boost nitric oxide levels. It's often used in pre-workout supplements to enhance muscle pump and improve workout performance. However, its ability to increase blood flow could also benefit erectile function. You can read more about the benefits of Nitrosigine for both workout performance and erectile function here and here.

Nitric oxide boosters can be a valuable addition to your supplement regimen if you want to improve your workout performance or address issues with erectile function.

Bottom Line

While pre-workout supplements can temporarily boost energy and performance, their potential impact on sexual health should not be overlooked.

Men who use these supplements should be aware of the potential risks and consider discussing their use with a healthcare provider, particularly if they have underlying health conditions or are experiencing symptoms of ED.

It's important to remember that while the research suggests a potential link between pre-workout supplements and ED, more studies are needed to understand this relationship fully.

In the meantime, men should consider other ways to boost their workout performance, such as maintaining a healthy diet, getting enough sleep, and staying hydrated.
