One of the most well-liked categories of fitness supplements is “pre-workouts,” or pre-workout vitamins.

Both competitive athletes and casual gym users use them.

Pre-workouts are meant to provide you with more physical and mental vigor as you exercise.

A pre-workout pill’s benefits might extend for up to two hours after you take the supplement.

Naturally, this depends on the components, the specific effects you’re interested in, and other elements.

Everything you need to know about pre-workout supplements is included in this article.

Everything, including effects, duration, advantages, hazards, and suggestions to keep in mind if you decide to use one.

 

KEY TAKEAWAYS

Pre-workout pills are one of the most regularly used dietary supplements and a well-liked product.

They are used by plenty of people, including athletes and fitness fanatics.

Research does indicate they may improve exercise performance, particularly for anaerobic power, and the majority are created to increase energy and performance during training and working out.

The high caffeine content of pre-workouts is the main safety issue.

By limiting yourself to one serving per day and abstaining from other caffeinated beverages during that time, you can reduce your risk.

✅ Pre-workouts may not contain what the label claims they do and may be tainted with illegal or otherwise dangerous ingredients because the FDA doesn’t monitor supplements.

✅ Think about purchasing a pre-workout supplement that has undergone independent quality testing.

 

What exactly is a Pre Workout?

Pre-workout pills fall under the category of dietary supplements created to help your workout by giving you more energy, stamina, and focus as well as maybe better performance.

They contain substances that widen your blood vessels, including arginine, to improve the “pump,” or blood flow to and from your muscles. Additionally, they contain caffeine, which may help you feel more energized. Additionally, some pre-workout pills’ creatine may improve your performance in demanding jobs.

The majority of pre-workouts are powders that you combine with water or juice. Some pre-workouts are offered for sale as drinks in cans or bottles or as pills. Pre-workout pills are widely accessible from numerous companies, and each one has a unique recipe.

A lot of pre-workout supplements include each ingredient along with the dosage per serving. Some pre-workout supplements merely identify their proprietary combination of ingredients, not the precise amounts of each ingredient.

According to studies, the following substances are found most frequently in normal pre-workout supplements:

  • beta-alanine
  • caffeine
  • citrulline
  • tyrosine
  • taurine
  • creatine
  • Niacin (sometimes referred to as vitamin B3)
  • arginine

The combination of any or all of these chemicals is what distinguishes the majority of pre-workout supplements. To enhance the flavor and appearance of the dissolved product, several manufacturers often add flavoring, coloring, and artificial sweeteners.

 

What’s the duration of a pre-workout?

The effects of the various substances in pre-workouts last for variable amounts of time. Caffeine and arginine are two of the most extensively researched pre-workout active substances.

It will take 60 to 90 minutes for these two ingredients to start working with the majority of pre-workouts. Caffeine’s maximal effects start to show up 60 minutes after consumption, whilst arginine’s effects start to show up 60 to 90 minutes afterward.

Pre-workout supplements with arginine increase blood flow by widening blood vessels. According to research, arginine’s half-life can range from 30 to 120 minutes, depending on the amount and the person.

The half-life of caffeine is approximately 5 hours long. According to research, the acute effects of caffeine begin to manifest themselves after an hour and can continue anywhere between 1.5 to 9.5 hours, depending on the person.

Given that caffeine and arginine have different half-lives, pre-effects workouts can last anywhere from 30 minutes and two hours.

Your experience with the onset and duration of pre-workout effects may vary because the research demonstrates a variation of half-lives for the key substances among individuals.

In the end, the following factors determine how long pre-workout effects last:

  • how much of each ingredient is in each serving
  • how many servings you drink in a certain amount of time.
  • Your body weight
  • Your level of activity
  • Your caffeine sensitivity

Is it okay to take a pre-workout?

Pre-workouts with multiple ingredients seem to be reasonably safe. Pre-workout supplements do, however, include a number of chemicals that, if taken in excess, may be dangerous. Here are a few possible side effects of pre-workouts.

The toxicity of caffeine

When taken in excess, caffeine can be dangerous and even fatal. Due to the number of fluids required, it is challenging to ingest enough caffeine in a traditional manner, such as by drinking coffee or tea.

However, it is much simpler to eat large amounts when using concentrated powders like pre-workouts that include high concentrations of caffeine. Therefore, these goods present a higher danger than caffeinated beverages.

Pre-workout users who also drink other caffeinated beverages could be in danger of caffeine overdose. Lower body weight individuals may be more vulnerable.

One 2019 study examined pre-workout side effects and intake patterns. The majority of those polled stated they consumed one serving each use, but 14% consumed two or more. 18% of respondents admitted to using pre-workout supplements more than once daily.

The following negative effects were mentioned by 54% of those who used pre-workout pills in the same study:

  • Skin repercussions
  • Heart conditions
  • nausea

These negative effects were more prevalent in females and those who ingested two or more servings of pre-workout per day.

High caffeine intake is linked to cardiac irregularities and nausea, whereas niacin promotes skin flushing. With dose, these effects become more pronounced.

Caffeine levels that result in death usually range from 5 grams or higher but can occasionally be as low as 3 grams, according to a study of human research. Caffeine levels in pre-workouts typically range from 250 to 400 mg per serving.

You would need to take only 7.5 servings of pre-workout to attain a 3-gram intake of caffeine with a product that had a high amount of 400 mg of caffeine per serving.

Although this is a lot more pre-workout than the majority of people would take in a day, it is certainly doable. It’s crucial to control your intake because of this.

The toxicity of Niacin

Niacin can have serious side effects at large doses, such as:

  • blood pressure that is dangerously low
  • hepatic injury that may lead to liver failure
  • Failure of numerous organs

According to research, niacin levels of about 3 grams per day can cause liver damage.

Niacin flush can be brought on by consuming far smaller levels of the vitamin—around 30 mg per day.

This disorder makes your skin red, itchy and heated to the touch. It usually disappears after an hour or so.

The average amount of niacin in some of the most popular pre-workout pills is 25.8 mg, but some of them can have as much as 41 mg. So it’s likely that after taking one serving of pre-workout, you might notice a niacin flush.

Check the quantity of niacin per serving on the product’s label to determine how much you’re actually consuming, and be sure to consume the recommended portion size.

Additional safety worries

Pre-workout supplement safety has not been well researched by scientists, so it is unknown whether these supplements have negative long-term impacts.

Additionally, other additives might change the negative effects of caffeine or amplify them. It is challenging to generalize about the safety of all pre-workout supplements because of this.

Even prohibited or dangerous components may be included in some supplements. That’s because the Food and Drug Administration isn’t in charge of overseeing pre-workout supplements in the United States (FDA).

Before using an ingredient in a supplement, manufacturers are not required to test it for safety in the United States. Companies can add ingredients to dietary supplements with little regulation unless they are expressly prohibited or banned.

Additionally, businesses are free to make any claims they want regarding the efficacy of their products as long as they don’t assert that a supplement treats, cures, or prevents a particular disease.

Therefore, when it comes to pre-workouts and other supplements, “buyer beware” actually applies.

Could have substances that are prohibited in professional sports

Prohibited substances could pose a safety risk. Additionally, it’s crucial to be aware that using some pre-workout supplements could result in your disqualification if you compete in a sport that demands to test for performance-enhancing substances.

Athletes have in the past taken supplements that claimed to contain unrelated components and tested positive for illegal substances after ingesting trace amounts.

For instance, a 2013 study discovered the methamphetamine analog N,-diethyl-phenylethylamine (N,-DEPEA), a prohibited stimulant, in the pre-workout supplement Craze.

In this rather well-known instance, a number of athletes had their eligibility for competition revoked after testing positive for a prohibited stimulant, which led to an examination and eventual discovery of the drug in the pre-workout formula.

A 2020 investigation of 17 supplement brands revealed the presence of many prohibited chemicals in varying concentrations and concoctions in the various supplements.

The following illegal stimulants were found in this study chemicals list:

  • deterenol
  • phenpromethamine
  • beta-methylethylamine
  • octodrine

It’s concerning that these illegal drugs can be found in pre-workout pills, and it’s unclear if this was done on purpose or by accident.

The dearth of information regarding the immediate and long-term effects of mixing different stimulants in different dosages that isn’t disclosed on the label is even more alarming.

It is up to the consumer to verify that a pre-workout supplement has been third-party tested, even though these compounds are illegal in the United States and supplement businesses are not compelled by law to publish test results for them.

At the very least, these drugs can cause significant trouble in the short term as coaches and players attempt to show that a positive drug test was inadvertent and brought on by contaminated supplements. These drugs have unclear health effects.

Consider going the extra mile to find a pre-workout supplement that has been put through independent testing if you’re a competitive athlete.

Safety regulations

Here are some tips for making pre-workout supplements safer if you decide to use them:

  • Limit your daily intake to one serving.
  • If you intend to take a pre-workout on the same day as another supplement containing caffeine or niacin, stay away from doing so.
  • Seek out goods that have undergone testing by independent organizations like Labdoor or Eurofins Scientific.
  • Ensure that every component is specified, along with the precise quantity per serving.
  • Do your homework on each ingredient to confirm what it is and learn about any potential hazards or adverse effects.
  • Steer clear of pre-workout supplements that claim to be proprietary blends but fail to disclose how many grams of each ingredient are present in a single serving.
  • No matter what pre-workout supplement you use, only take one dose—or half a dose if you’re on the smaller side. This is crucial while utilizing a pre-workout supplement for the first time.
  • Consult a doctor to determine whether a pre-workout is safe for you if you take medication or have any medical conditions. It could be useful to display the pre-workout supplement’s ingredients list to them.

Who ought to consume a pre-workout?

Manufacturers of pre-workouts typically target bodybuilders, powerlifters, and other weightlifting aficionados when marketing their products. Other athletes may use them as well.

Caffeine, in particular, has been shown to improve both physical and mental performance; but, as your tolerance to caffeine increases over time, these advantages fade.

A pre-workout supplement may be advantageous for athletes with varying levels of endurance, strength, and body. Apart from caffeine, several of the components are focused particularly on weightlifting-related activities.

Pre-workouts can be appropriate for most high-intensity sports as long as you follow the necessary precautions, especially if you’re resistance training or engaging in other weightlifting and maximal effort exercises.

 

What are the benefits?

Pre-workout vitamins do have potential benefits for focus and performance at the gym, despite safety issues and overzealous marketing.

The particular performance component you’re looking at will determine how beneficial pre-workout supplements are in significant part.

For instance, one study discovered that using a pre-workout pill that contained caffeine dramatically enhanced anaerobic peak power and mean power.

The Wingate Anaerobic Power Test, a widely used evaluation of the capacity to perform strong effort over shorter time intervals, was used to test these.

But according to the same study, taking a pre-workout did not increase upper body maximum strength or upper or lower body maximal explosive power, as determined by tests for bench press 1-rep maximum, medicine ball throw, and vertical jump.

Another analysis of pre-workout supplements’ efficacy suggests they might be beneficial.

  • increase physical stamina
  • enhance mood
  • increase lean muscle (when used while resistance training)

Pre-workouts have the ability to enhance a number of physical performance factors. But generally, there is still much to learn about the potential advantages of pre-workout supplements.
