Powerful pre-workout blend -
Our team works hard to be transparent about why we recommend certain supplements. We support supplements that are evidence-based and rooted in science.
We value certain product attributes that we find to be associated with the highest-quality products. Our team of experts has created a detailed, science-backed methodology to choose the supplements we recommend.
You can read more about our dietary supplement methodology here. In addition to our research, we tested several electrolyte and protein powder supplements in the Verywell Testing Lab , preparing and serving them as directed by the manufacturer. When testing, we evaluated each product for the following six critical criteria:.
Pre-workout drinks vary in their degree of testing and regulation. The FDA does not review dietary supplements for safety and effectiveness before they go to market.
This includes electrolyte and protein powders, as well as BCAA and creatine supplements, so choosing a quality product from a trusted brand is important. Note that bottled drinks are considered beverages, and are therefore subject to the FDA's food and beverage regulation.
If you are a competitive athlete, you may want to choose products that are third-party tested for substances banned in sport like Informed Sport Certified or NSF Certified for Sport , or opt for an FDA regulated bottled, ready-to-drink beverage.
Pre-workout drinks typically come in liquid form or as powders that must be mixed with liquid. Ready-made drinks can be convenient because they don't require mixing, but powders allow you to control your dosage and are more environmentally friendly.
Single-serve powder packets are also easy to stash in your gym bag. It is essential to carefully read the ingredient list and nutrition facts panel of a supplement to know which ingredients and how much of each ingredient is included, relative to the recommended daily value of that ingredient.
Please bring the supplement label to a healthcare provider to review the different ingredients contained in the supplement and any potential interactions between these ingredients and other supplements and medications you are taking.
There are many pre-workout drinks available for exercise and athletic performance, but some ingredients lack scientific backing to support their efficacy and safety. Take a look at the NIH list of Dietary Supplements for Exercise and Athletic Performance to learn more about the safety and effectiveness of common ingredients athletic drinks and sports supplements , and consider consulting with a healthcare professional.
If you are a competitive runner, it is important to choose third-party tested supplements that are free of banned substances. Many pre-workout drinks contain high levels of caffeine. Accepted amounts of caffeine in pre-workout drinks are typically three to six milligrams per kilogram of bodyweight.
However, some individuals may find they are sensitive to caffeine, and high levels can lead to a fast heartbeat, nervousness, difficulty sleeping, and jitteriness. This means that as a consumer, we may not really have a good understanding as to the ingredients, dosing, and if the claims are valid on the product.
As a dietitian, my main concern with athletes or recreational exercisers taking pre-workouts is that it may contain dangerous levels of caffeine…and unknown doses of ingredients we are generally unaware of, since again what is in the product does not necessarily have to match what is on the label.
The recommended dosage will depend on the ingredients in your pre-workout drink. Below are recommendations for specific ingredients you may find in pre-workout drinks:. Carbohydrates : Carbohydrates are the body's preferred source of energy, so getting enough carbohydrates through your diet is important for adequate fueling.
Carbohydrate needs will vary based on activity type, intensity, and duration, as well as other individualized factors. For pre-workout fueling specifically, the American Academy of Nutrition and Dietetics recommends that consuming one to four grams of carbohydrates per kilogram of body weight one to four hours before prolonged exercise over an hour.
Pre-workout drinks often contain sugar as the carbohydrate source because it is quick absorbing fuel. Be mindful of the amount of added sugar in drinks, and make sure the amount is suited to the duration and intensity of your runs to avoid excess sugar intake.
Another thing to consider is individual tolerance of sugar amounts before, during, and after runs, as high amounts of added sugar consumed right before or during runs can cause gastrointestinal discomfort in some.
Caffeine: While caffeine tolerance varies from person to person, accepted recommendations of caffeine for improving performance are generally three to six milligrams per kilogram of body weight taken 60 minutes before exercise. Guidelines recommend consuming no more than milligrams per day, as more than this can lead to symptoms such as restlessness, headaches, insomnia, and anxiety.
After this, stores can be maintained with three to five grams per day. Studies consistently show that creatine is safe for healthy adults when used for weeks or months. While side effects are rare, they may include cramping, weight gain, muscle stiffness, and stomach upset.
Protein: While amounts will vary based on activity and goals, the International Society of Sports Nutrition recommends active individuals aim to consume 1.
This should be spread throughout the day. Note that consuming excess amounts of protein beyond your needs will not lead to greater muscle gains. Beta-alanine: The typical dose of beta-alanine is 4 to 6 grams per day.
High doses of beta-alanine milligrams or more, or more than 10 milligrams per kilogram of body weight can cause paresthesia tingling in the face, neck, and other parts of the body. A pre-workout drink can help you stay hydrated and provide you with carbohydrates, protein, and electrolytes, which can help you through your workout.
They often also contain caffeine which can provide you with a boost. Not all pre-workout drinks are created equal though, and the efficacy will depend on the ingredients it contains. Pre-workout drinks should not take the place of complete meals or whole foods. Samuel suggests taking a pre-workout drink mins before beginning your workout.
This depends on what you are looking for out of your pre-workout drink. For energy, look for quick-absorbing carbohydrates. Caffeine may also help boost performance, but does not provide true energy in the form of calories. Electrolytes such as sodium, potassium, calcium, and magnesium may also be beneficial before long or sweaty workouts to help replace electrolyte losses and aid in hydration.
Protein, creatine, and antioxidant drinks can help support muscle repair and growth. Tamar Kane, MS, RD , is a plant-based Registered Dietitian and marathon runner.

The main benefits of this ingredient are increased muscular endurance, better aerobic capacity and reduced muscle soreness This is because L-citrulline is a precursor to the amino acid L-arginine, which in turn is a precursor to nitric oxide in the body Nitric oxide is a vasodilator, and vasodilation is a process that widens blood vessels, delivering oxygen and nutrient-rich blood to various tissues—including muscles.
By increasing nitric oxide levels through citrulline supplementation, one may improve blood flow to muscles and enhance performance. An effective dose of citrulline malate is around 6 to 8 grams, and an effective dose of L-citrulline is 4 to 6 grams taken prior to a training session Creatine is one of the most widely used and well-studied sports supplement ingredients.
Creatine is sometimes included in pre-workout supplements for consumers who want a pre-workout formula that covers all of their bases. Creatine is effective in dosages between 3 to 5 grams per day, depending on your body weight L-theanine is an amino acid that works in conjunction with caffeine to improve cognition, reaction time and focus The addition of L-theanine to highly caffeinated pre-workout supplements has been shown to reduce some of the unwanted side effects of high caffeine consumption, which include an increase in heart rate, restlessness and anxiety The effective ratio to reduce these side effects is two-to-one L-theanine to caffeine Although we think of workouts as stress relieving, intense cardio and resistance training sessions put the body under a significant amount of strain.
L-tyrosine has been found to work best in stressful situations, including intense training sessions or athletic competition. The men who took L-tyrosine cycled for longer than the placebo group but reported similar exertion levels and had a similar heart rate to those in the placebo group.
The study authors concluded that L-tyrosine supplementation may have an effect on endurance capacity under stress Taurine is an ingredient commonly found in energy drinks and pre-workout powders because of its demonstrated antioxidant effects 42 and potential athletic performance benefits.
These benefits include improvements in endurance, peak power generation, electrolyte balance and improved recovery The recommended dose of taurine is 1 to 2 grams taken prior to exercise.
Related Post: Common Pre-Workout Supplement Ingredients and What They Do. My initial recommendation is to read the new label carefully and compare it to a pre-workout you've used in the past. If your normal pre-workout powder contains milligrams of caffeine and you decide to slam a full scoop of Pre-Kaged Elite with milligrams of caffeine per serving, then you may experience some unwanted negative side effects like jitters, headaches and anxiety.
In this case, it may be smarter to start with a low dose, such as a half-scoop, and gradually increase to a full-serving size over time based on your tolerance. Another potential mistake to avoid is taking pre-workout supplements too late in the evening.
Most pre-workout powders contain high levels of caffeine that, when taken too close to bedtime, can interfere with your sleep. This last one should go without saying, but be sure to follow the supplement label directions and do not exceed the recommended dosage level.
For these potent pre-workouts, exceeding the recommended dose can lead to serious side effects, such as heart palpitations, anxiety or even cardiac arrest. The optimal time to take a strong pre-workout supplement is anywhere from 15 to 30 minutes before training.
This will give the product enough time to digest, absorb and allow the beneficial effects to begin taking place. You may also only want to use a strong pre-workout for specific instances, such as prior to a particularly demanding workout, when attempting a new one-rep max or even to power through an early morning training session.
These stronger products are also great for individuals who have built up a high tolerance to caffeine and need a more substantial dose to achieve the desired effects. There are a number of instances in which taking a strong pre-workout may not be the best option.
Adding a high stimulant pre-workout supplement to an already highly caffeinated diet can cause some serious unwanted side effects, including headaches, dehydration, anxiety and insomnia.
You should also take into account your sensitivity to caffeine and other stimulants. Many pre-workout supplements contain a substantial amount of caffeine that may be tolerable for a larger individual, but too strong for a smaller one.
These are all instances where you may want to avoid a pre-workout supplement or at least seek a medical professional's expert opinion. Most average strength pre-workout supplements contain between and milligrams of total caffeine per serving, which is equivalent to about two to three cups of coffee This is generally enough caffeine to give individuals the boost they need to attack their training session.
The strength of a pre-workout supplement is not just about the amount of caffeine per serving. The most common ingredients found in pre-workouts, aside from caffeine, include L-citrulline or citrulline malate, beta-alanine, betaine and individual amino acids like taurine and tyrosine.
Refer to our individual ingredients section above to learn more about these ingredients and the dosage levels that will actually benefit the user. There are several organizations that test pre-workout supplements to ensure their safety and effectiveness, such as NSF International, Informed Sport and Labdoor.
This is also very beneficial for athletes who compete in drug-tested sports and want to ensure their products are free of banned substances. These reviews often give great insight into how the product made someone feel, the results you can expect from product use and the best flavor options to try.
Another factor to consider is how the product is flavored and sweetened. If you prefer all-natural products, then you should read the supplement facts label carefully to see if the product contains any artificial sweeteners, colors or flavors.
You should never overspend on the purchase of a supplement. Consider your specific needs, goals and budget to make an informed decision about which product will provide you with the most value. The first red flag is a supplement facts label that contains proprietary blends, which combine multiple ingredients and list them as a single item on the product label without disclosing the specific quantities of each individual ingredient used.
This lack of transparency makes it difficult to evaluate the safety and effectiveness of the product and usually means that the product is inadequately dosed.
Athletes who participate in sanctioned drug-tested competitions also need to take precautions when trying out a new pre-workout supplement. They should ensure the product has been third-party tested and is certified safe for sport, meaning the product is free from banned substances.
I'm a certified sports nutrition coach and NASM-certified personal trainer who has tried countless pre-workout supplement formulas. In addition to my own experience in the fitness and supplement industry, all of these pre-workouts earn high scores when put through our scoring algorithms for caffeinated and non-stim pre-workout supplements.
These algorithms are based on a number of factors, including:. We also receive input from our panel of expert contributors, which includes registered dietitians and highly credentialed experts in sports nutrition and exercise science.
Learn more about our nutrition and supplement review process , as well as our pre-workout testing methodology and stim-free pre-workout testing methodology. From our list, Pre-Kaged Elite has the most caffeine at milligrams per serving. At this dosage level, you should monitor your intake of caffeine from other sources, especially if you're sensitive to caffeine.
The FDA has determined milligrams to be an amount not generally associated with dangerous, negative effects, but individual sensitivity to caffeine varies For example, a pound male and pound female would have a different experience using the same pre-workout.
In this context, we'll classify a strong pre-workout as a supplement that has multiple active ingredients caffeine, L-citrulline, beta-alanine, betaine, taurine, etc. included in clinically effective dosages.
Yes, there are some potential side effects associated with taking a strong pre-workout supplement. These side effects can vary depending on the ingredients in the supplement and the dosages used, as well as individual factors such as sensitivity and tolerance to certain substances.
Some possible side effects include jitters, anxiety and trouble sleeping 45 , as well as increased heart rate and blood pressure due to the intense caffeine levels 46 and a feeling of hot and itchy skin known as paresthesia from the beta-alanine If you have any concerns about the safety of a particular supplement, you should consult with a healthcare professional before use.
Compared to an average pre-workout containing two or three active ingredients included at modest dosage levels, a stronger pre-workout should have more active ingredients, higher dosage levels and therefore more pronounced beneficial effects.
These stronger pre-workouts should significantly improve your energy levels, focus, endurance and pump during training. The answer to this question can vary significantly depending on an individual's sensitivity to caffeine, the other ingredients in the supplement and the activities performed after taking it.
This feeling is often exacerbated when using a pre-workout because the supplement increases the amount of energy you're able to utilize during your workout. Yes, dimethylamylamine or DMAA was banned by the U.
Food and Drug Administration in for use in dietary supplements because it had been shown to increase the risk of cardiac events such as heart attacks For serious athletes, bodybuilders and fitness enthusiasts, the strongest stimulant pre-workout supplements are definitely worth the often higher price point for a more potent product.
Some people deal with this by taking a second scoop; however, that can be dangerous when using a pre-workout that already has more than milligrams of caffeine per scoop.
What normally does the trick is trying a new pre-workout that has slightly different ingredients and dosage levels. Plus, there's just something exciting about trying a new pre-workout for the first time, timing it perfectly so that you feel supercharged and ready for your workout.
If you need that extra boost for your next training session, consider trying any one of the high powered supplements on this list. These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any diseases.
