One of the most popular supplements on the market, pre-workouts often increase energy, blood flow, endurance, power, and even hydration. As such, you can find different combinations of beneficial ingredients (like caffeine, citrulline, and beta-alanine) in the form of powders, pre-made drinks, small liquid shots, and even chews and gum.
But with the amount of options, it’s easy to get lost. We’ve spent years testing out the best pre-workouts for weight loss, training sessions, and more. Our on-staff certified personal trainers, nutrition coaches, USA Weightlifting coaches, and athletes have personally tested more than 100 different pre-workout products. After also working with a registered dietitian, here are what we consider to be the best pre-workout supplements for any fitness goal.

How We Tested and Chose the Best Pre-Workouts
We tried a lot of pre-workouts (and hit a lot of PRs) before landing on this list. Our team of BarBend expert product testers, including certified personal trainers, athletes, and nutritionists, tried 70 different pre-workout supplements to find something that works for every customer. Here are the criteria we reviewed.
- Value: We made sure that all of the prices of the products on this list were in line (in our eyes, at least) with the ingredients included and the potency of the formula. Most pre-workouts should cost between $1.00 and $2.00 per serving.
- Transparency: We prioritized products that have easy-to-read nutrition labels with crystal-clear dosing.
- Dosage: Many pre-workouts have research-backed ingredients but don’t use research-backed doses. For the most part, we have only included picks on this list that contain the proper dosage for their ingredients.
- Third-Party Testing: We prioritized products from companies that employ a third party (like Informed Choice or NSF) to test their products. This helps ensure label accuracy.
- Taste: If you don’t enjoy the way a supplement tastes, you’re probably not going to enjoy drinking it. While we know everybody is different, we still like to give some personal perspective on the flavor.
- Solubility: For most of us, we like to toss a scoop in a shaker bottle and head to the gym. Considering pre-workout chunks are pretty bitter and difficult to swallow, good solubility is a must-have.
- Side Effects: While some people may feel tingly or jittery after a pre-workout, others may not. That’s why we have a variety of testers with different bodies and tolerances to give a well-rounded perspective on the side effects.
- Ingredients: Our team worked closely with a dietitian to review all the products we listed on this page. We chose pre-workout supplements with ingredients that are listed as safe dosages for most adults.
Benefits of Pre-Workouts
We’ve said it before, we’ll say it again: Everyone is different. So, you may not experience every single effect a pre-workout has to offer. With that said, there are many benefits most pre-workout supplements have to offer.
- More Energy: Caffeine (often the primary ingredient in pre-workouts) is a stimulant, but it is also linked to better power, endurance, perceived exertion, and even cognition. (12)(13)(14) A study published in Medicine & Science in Sports & Exercise found that when compared to a placebo, 10 athletes improved their speed, reaction time, movement time, and decision-making time when supplementing with caffeine. (15)
- Improved Blood Flow: Most brands include citrulline in their formulas to help promote blood flow to potentially help increase your muscular endurance and promote muscle pump. While there’s some research that shows citrulline may help promote improved blood flow in adults, there is limited conclusive evidence yet. (31)
- Boosted Performance: The beta-alanine found in many pre-workouts is known to help reduce lactate concentrations, which may improve endurance and performance. (32) It can also bring on the skin-tingling sensation known as paresthesia, so start with small doses at first.
How Much Do Pre-Workouts Cost?
The cost of pre-workout varies somewhat primarily based on the ingredients used and the doses of those ingredients. The pre-workouts we picked range from around $1 per serving to about $2.99 per serving. Products that prioritize transparent dosing — meaning the ingredients aren’t wrapped up in obscure blends — will typically be pricier. Check out how each option compares when it comes to pricing.

What to Consider Before Buying a Pre-Workout
These sorts of products can make some folks a little concerned about side effects and unintended consequences. While they are legal, it’s important to know the risks to high caffeine consumption, or how these ingredients interact with pre-existing conditions.
It’s always a good idea to consult with a performance dietitian or your physician on what the best supplements are for you. There are some things worth keeping in mind when you’re trying to figure out which is the best pre-workout supplement for you.
Ingredients
No two pre-workout supplements are exactly the same. Different brands and products have different formulas. So, before you buy any supplement, be sure to read the ingredient label thoroughly and consult your personal dietitian or physician if you have any pre-existing conditions.
In most pre-workouts, you can expect to find caffeine. This ingredient helps provide energy but can have some potential downsides, too. It can cause anxiety, diarrhea, and maybe even temporary high blood pressure. This doesn’t mean that caffeine is inherently bad for you. It just means everyone has a different tolerance for caffeine. It’s important to consider your total caffeine throughout the day.
For example, if you’re having 2 cups of coffee, 1-2 scoops of pre-workout, and a tea or soda with caffeine, that amount can quickly surpass the recommended maximum daily total intake for adults which is ~400mg of caffeine per day.
Perhaps the most common pre-workout ingredient that isn’t caffeine (or flavoring) is beta-alanine, which typically causes paresthesia, a “tingling” sensation on the skin. It’s temporary and harmless, and while some love the feeling of the ingredient “kicking in,” not everyone likes it.
Some pre-workout products also have banned substances. These aren’t necessarily illegal or dangerous, but they may not be permitted if you’re a competing athlete. Read the rules of your competing federation or organization carefully to ensure you’re not sipping a supplement with prohibited ingredients. In addition to banned substances, the NCAA and other elite organizations have rules on the amount of caffeine that can be consumed which is why it’s important to consult with a performance dietitian who understands these rules and regulations.
Dosages
Just as different formulas have different ingredients, they also provide varying doses of these ingredients. For most pre-workout ingredients, there isn’t a daily recommended value, which can make it a little challenging to discern whether the dose is adequate.
For an ingredient like caffeine, consider that the daily maximum of caffeine considered safe for adults is about 400 milligrams. For other substances, like beta-alanine, in a loading phase, you will want to be in the range of 4-6g per day, divided into 2 doses during the day.
Third-Party Testing
Pre-workout supplements aren’t regulated by the FDA, so it’s best to prioritize products that are third-party tested. That means that an independent company tested the formula to guarantee that the ingredient label accurately reflects the ingredients and doses. Keep in mind, when products say “proprietary blend,” that means you won’t know the exact ingredients and their exact amounts, so proceed with caution.
For elite and NCAA athletes, we highly recommend avoiding anything with proprietary blends where you don’t have knowledge of or control over the ingredients and the amounts you’re ingesting. For these special groups who will be drug tested, sticking to products with certifications from NSF Certified for Sport or Informed Choice for Sport is crucial to ensure the products have been verified to help you avoid testing positive for a banned substance. No supplement is taken without risk, but this can help minimize that risk.
For the general gymgoer, or someone not being tested, look for the USP label:

Flavors
You don’t want to sip on a supplement that tastes disgusting, right? Luckily, pre-workout supplements come in a pretty wide variety of flavors. So, chances are, there’s something for everyone. Before you settle on one flavor, take a peek through the product reviews.
When Should I Take Pre-Workout?
Wondering when to take a pre-workout? As the name implies, you want to take your pre-workout before you train. The general rule is to mix the powder (if you’re taking a powder, not a pill) in about eight ounces of water and ingest it 30 to 60 minutes before training. This time can allow the ingredients — like caffeine, beta-alanine, and taurine — to absorb and start taking effect. (25)
It might be helpful to take particularly high-dose and large pre-workouts a bit longer before training to allow your body more time to process the extra ingredients, though. On the flip side, if you like to take a long warmup, taking it closer to your arrival might allow for the effects to not kick in fully until you’re done warming up.
If you train at night, you may want to avoid caffeinated pre-workouts. Some pre-workouts contain 150mg of caffeine, with certain products packing 300mg or more. The half-life of caffeine has a huge range from three to nine hours, depending on the individual. If you take 300mg at 5 p.m., you could still have 150mg circulating in your body at 8 p.m. on the low end. If it is still circulating, it may make it challenging to wind down and get quality sleep.
Other Pre-Workouts We Tested
While we narrowed down the best pre-workouts to our list above, they weren’t the only products we tried. Here are a few others we tried, but we didn’t think they were the best of the best.
- Cira Pump Caffeine-Free Pre-Workout: This is a caffeine-free pre-workout that we just didn’t love more than our stim-free pick above. Our testers generally find Cira supplements a little too sweet and that was the case here, too.

What Ingredients Are In Your Pre-Workout Supplement?
Not all pre-workout ingredients are useful, while others might be surprisingly beneficial. Here’s a rundown of the ingredients that you’ll usually find and actually want in your pre-workout.
Wondering whether you can build a tolerance to pre-workout? Learn more in our video.
Let’s talk a bit more about those ingredients and what the research says in regard to each of them.
Caffeine
Caffeine is associated with alertness, endurance, power output, strength, and perceived exertion. (12) The FDA puts one small cup of coffee at 100 milligrams of caffeine, while a tall (355ml) coffee from Starbucks has about 235 milligrams.
Pre-workouts typically contain anywhere from 80 to 350mg of caffeine. An effective dose is three to 6mg per kilogram of body weight.
Creatine
As the best-researched ergogenic aid besides caffeine, creatine helps power output, anaerobic capacity, and fatigue, all while increasing muscle size by drawing more water into muscles. You don’t have to take it with your pre-workout since it’s an anytime supplement — the point is to increase the creatine in your muscles over time rather than loading creatine quickly.
Three to five grams of creatine daily is effective. (22) The best pre-workouts with creatine may add creatine to their formulations, but ensure it’s an effective dose and something you take every day. If you’re not planning on taking pre-workout daily, it makes more sense to take the best creatine supplements separately every day since it matters how consistently you take it.
Citrulline
Older research suggested that five or so grams of citrulline, an amino acid that’s found in high amounts in watermelons, may help with circulation and thereby improve most areas of performance, from endurance to power output. (8) However, more evidence is needed to confirm the effects of citrulline on performance. (8) Available studies and meta-analyses have shown mixed results, and the benefits are minor and inconclusive at best.
Beta-Alanine
Beta-alanine is linked to improved endurance, both in cardio-focused intervals and strength training with higher reps (between 60 and 120 seconds of continuous work). It’s also known for the tingly feeling (paresthesia) you may feel in your extremities when you take it. Because it allows you to endure more, it may help with hypertrophy. The standard dose is 1.6 to 3.2 grams.
If you can’t stand the tingles, splitting the dose into 0.8 to 1.6 grams every three to four hours can prevent the paresthesia. (17) You can also opt for the best pre-workouts without beta-alanine.
Betaine Anhydrous
Found in beets and leafy greens, betaine is best known for links to power output, blood flow improvements, and muscular endurance, but it might also slightly decrease post-exercise cortisol, which can actually be helpful in your body’s response to stress. An effective dose is 2.5g per day, split into two doses for resistance training. (23)
Taurine
Taurine may help with improving focus. Since it might draw water into cells, it may enhance recovery and muscle cramps, as well. You can take up to six grams per day about one to two hours before exercise. (25)
Tyrosine
Also used for “focus,” data suggests tyrosine may reduce acute stress — like exercise — by helping you produce adrenaline and dopamine. Research has only been performed on people taking at least 500 milligrams, and a minimum effective dose hasn’t been established, but look for at least 500 milligrams.
An effective dose might be 100 to 150mg per kilogram of body weight, taken an hour before exercise, but large doses can cause gastrointestinal distress and might need to be split up. (24)
Best Pre-Workout Supplements FAQs
What does a pre-workout do?
It depends on what’s in the pre-workout, but ingredients like caffeine, beta-alanine, and betaine have been linked to higher energy levels, better power production, and improved endurance. Some ingredients, like tyrosine and taurine, may even improve focus.

There are so many options on the market for pre-workouts, and many seem to have similar formulas. One that stands out from the noise with a potent and robust ingredients list is Transparent Labs BULK. It has well-dosed levels of citrulline, beta-alanine, and betaine to potentially support blood flow and endurance. You’ll also find a moderate helping of stimulants and focus ingredients with 200mg of caffeine along with alpha-GPC, theobromine, and taurine.
Can I take pre-workout every day?
Strictly speaking, there’s nothing stopping you from doing so, but it is usually ill-advised. The more regularly you take pre-workout, the less effective each dose usually becomes because you build up a tolerance. We generally try to only take pre-workout before particularly challenging sessions or when we really need an extra kick of energy. It’s also a good idea to occasionally take some time off from pre-workouts. You’ll be surprised how much more you might notice the effects after a week away from the ingredients.
How long does pre-workout last?
Everyone’s body processes the ingredients in pre-workouts differently, so it’s difficult to pin down an exact time. That said, you can usually feel the effects of a pre for anywhere from two to six hours, depending on a variety of factors. What and how recently you’ve eaten, how strong the pre-workout is, and your own biochemistry all may play a role in how long a pre-workout lasts.
How much does a pre-workout cost?
The short answer here is that the price of a pre-workout supplement will vary greatly depending on the ingredient list, dosages, and quality of each ingredient. Most fluctuate between about $1.40 to $3.00 per serving with the average price costing about $2.05 per serving. Although this may seem expensive to some, you tend to get what you pay for with pre-workout supplements.
What is dry scooping pre-workout?
Dry scooping refers to taking a scoop of pre-workout powder dry, as the name implies, without mixing it in a shaker bottle or cup, then (optionally) washing it down with water after. It can be dangerous, though, as mixing the pre-workout with water allows your body time to absorb the ingredients more slowly. We advise against it and always recommend following the label of your pre-workout supplement for instructions on how best to take it.
Is it better to drink pre-workout before or during workout?
It’s best to drink your pre-workout before going to the gym, as it can take a good thirty minutes to “kick in.” For optimal results, and if you’re in a hurry, it may be best to take pre-workout on an empty stomach so that it digests quickly.
