Get your shaker cup ready: We rated this a 4 out of 5 for solubility. RELATED: Huge Supplements Discount Code. RELATED: Onnit Coupon Code. The Performance Blend is a combination of BCAAs, glutamine, and beta-alanine. Out of those three, beta-alanine has the most research backing up its use as a performance aid.

When taken consistently for four weeks, beta-alanine can increase muscular endurance and help delay fatigue 4. The second category is the Power Blend, and contains a handful of ingredients linked to maintaining hormone health.

The combination of d-aspartic acid 18 , longjack extract 19 , and nettle root extract 20 may assist with supporting testosterone production. The Support Blend is the third category and contains red clover extract, luteolin, and resveratrol. These ingredients can support mood when consumed in an adequate dose.

While this product contains ingredients with a decent amount of evidence to suggest they could positively affect your workout, the use of proprietary blends makes it difficult to know how effective the doses are.

Our list of the best stim-free pre-workouts has more recommendations for anyone trying to steer clear of caffeine or other stimulants.

Although expensive, 4 Gauge pre-workout supplement provides research-backed doses of high-quality and nature-based ingredients to give users the best possible outcomes. Taking a closer look at the ingredient label, I can see that 4 Gauge uses research-backed ingredients to provide a balance between strength, focus, energy, and muscle pumps.

Perhaps more impressive is the combination of caffeine and L-Theanine found in the product. When taken together, this dynamic duo can support increased energy levels, enhance cognitive function, and help ease levels of daily stress 5.

If you came looking for incredible muscle pumps, grab your dumbbells or adjustable dumbbells and listen up.

The research-backed combination of citrulline malate 3 and beetroot extract 17 can contribute to significant increases in nitric oxide production, supporting blood flow and nutrient delivery to your muscles. The downside? Good for: Those who want an energy boost without the caffeine crash after their workout.

Pre-Lab Pro is vegan and vegetarian-friendly, allergen-friendly, non-GMO, soy-free, gluten-free, and free from artificial flavors and synthetic additives. Pre-Lab Pro has 80 milligrams of caffeine per serving, which is less than a standard-sized Red Bull can and much less than the several hundred milligrams found in most pre-workouts.

When combined, these two substances have been shown to increase energy and reaction time. GGR Senior Editor and certified personal trainer Nicole Davis tried this pre-workout supplement, which unfortunately only comes in one flavor: Natural Berry.

Tastes like drinking a Flintstones vitamin. Transparent Labs Stim-Free Pre-Workout is an uncaffeinated pre-workout powder that will not give you the jitters or tingling commonly associated with pre-workout supplements.

This pre-workout contains a blend of citrulline malate, beta-alanine, L-tyrosine, taurine, and elevATP, a compound claimed to increase ATP activity in muscle cells. We gave Transparent Labs Stim-Free pre-workout a near-perfect 4. It is essentially a caffeine-free version of their standard pre-workouts for those who prefer to train at night, or simply want all their caffeine to come from coffee.

The primary ingredient is citrulline malate, which a review 27 stated was vital for nitric oxide production to help support skeletal muscle function and improve blood flow to muscles. I felt focused at all times and there was no energy crash at the end of my workout.

Sodium and potassium act primarily as electrolytes to promote hydration, though studies 28 tell us they can also assist in helping you get a pump. Similarly, beetroot powder is added for color and can also help improve nitric oxide production Amanda Capritto, GGR staff writer and expert product tester who also tested this pre-workout, said the Cherry Limeade flavor was tasty and not overly sweet, though she said it was difficult to get it thoroughly mixed.

If you are looking for a clean pre-workout supplement with a simple list of natural vitamins and minerals, Naked Nutrition's Stim Free Pre Workout may be for you.

It is gluten-free, vegan-friendly, and non-GMO. Also, there are no proprietary blends in Naked Energy, which is third-party tested. It does have one gram of creatine, which is better than nothing but not enough to cause a significant uptick in strength and muscle mass. When it comes to flavors, Naked Nutrition has three—all of which contain no artificial sweeteners: Unflavored, Fruit Punch, and Citrus.

Nicole tried the unflavored option and said it was a bit bitter, though it would go well with a sports drink. The 90 cents per-serving cost is another big plus in our books, and each container comes with 50 two-scoop servings. While Gorilla Mode receives mixed reviews, it is formulated with all the key ingredients you want in a pre-workout drink to improve performance in the gym.

However, if you are sensitive or want to avoid stimulants, this may not be the supplement for you. Gorilla Mode has been formulated specifically to support increased energy, focus, muscle strength, and endurance.

The combination of L-Citrulline 16 , GlycerPump 24 , and Agmatine 25 can boost nitric oxide production, promote increased blood flow, and improve intramuscular hydration.

Several people tested Gorilla Mode for us, including Jacob Penner, USA Weightlifting L-2 coach and owner of Endless Strength Weightlifting Club. Moving down the ingredient list, we see a unique blend of nootropics designed to support enhanced focus and mood 9.

The combination of L-Tyrosine 6 , Kanna 26 , and Huperzine A 22 are known for their cognitive-supporting properties and their ability to help ease daily stress. Add in the milligrams of caffeine and 2, milligrams of creatine per serving and you have yourself a pre-workout cocktail that could help get you closer to your goal of bigger, stronger muscles 8.

There are some countries, like Australia, and some sports associations where the stimulant is banned. In terms of taste, we had mixed results.

I mixed one scoop with 20 ounces of water, and it tastes like all three flavors of a rocket pop at once. It just tastes like something sweet. Endura-Formance is formulated with all the key ingredients one would look for in a pre-workout drink. While the taste is not for everyone, most users experienced improved performance at the gym.

Endura-Formance is their premium pre-workout product containing research-backed ingredients shown to enhance muscular endurance and speed up the recovery process after a tough treadmill workout. Certified personal trainer and former competitive triathlete Amanda Capritto used Endura-Formance when training for her races and says it always gave her a boost, giving it a 5 out of 5 for effects.

As a reminder, sodium is an electrolyte that can help fuel longer workouts that leave your clothes drenched in sweat. Amanda points to two other ingredients that make this a perfect fit for runners: PeakO2 and S7.

We should also point out that this is a stimulant-free product, so there is no caffeine, and no big energy boost like you might get from other products.

Jacob Penner, a USA Weightlifting coach who has been testing different pre-workouts for years, used Genius PRE a number of times to check out its efficacy. He gave it a 4 out of 5 for its workout effects. Pretty much by the time I was done lifting, the pump was fading.

In terms of formulation, we gave this a 4 out of 5, only knocking it down a point because it lacks a stimulant, which is something most people are looking for in a pre-workout. However, by all other accounts, this checks a lot of boxes with its ingredient lineup.

Amanda Capritto, certified sports nutrition coach and GGR senior staff writer, points out that there are clinically-backed ingredients and dosages of key pre-workout players like l-citrulline malate, carnosyn, betain anhydrous, l-tyrosine, l-arginine, and taurine.

There are also nootropics like choline 31 and huperzia serrata 22 , which support cognitive function. I felt almost euphoric taking this, actually.

Nicole Davis, GGR senior editor, gave Blackwolf a try before one of her workouts. Each serving contains 6 grams of citrulline malate, which has been shown to promote increased blood flow 2.

This can contribute to improved oxygen delivery to your muscles during workouts, as well as faster removal of metabolic byproducts caused by intense training sessions. Similar to citrulline, L-Arginine Alpha-Ketoglutarate works as a nitric oxide booster 32 to help you get more out of your workouts.

The 3. This product also contains creatine monohydrate 8 and betaine anhydrous 33 , both of which can assist with muscle strength and exercise performance.

Are important ingredients like caffeine, creatine, citrulline, citrulline malate, and beta-alanine included? Are there high levels of stimulants that have been shown to have detrimental effects?

Stimulants to keep an eye out for: High levels of caffeine, dendrobium, synephrine, DMAE, rauwolfia vomitora. This is subjective, but we base it on the views of our testers, as well as what the general consensus is in online customer reviews. We took the individual flavor and full range of flavors into consideration.

How well does this product dissolve in the suggested amount of liquid? Are there floaties? Is it grainy? Is it super thick or super thin?

Does it separate after a few minutes? What do customers think of the product? Are reviews consistent? Does the company interact with customer reviews?

Made with green coffee extract, caffeine, Vitamin B6 and cayenne extract, Red-Cell is ideal as a pre-workout or as part of a weight loss programme.

Coffee: A cup of black coffee with or without sugar before your workout is a great way to up your energy levels. Bananas: Rich in starchy carbohydrates, one banana will contain around 14g of sugar, made of glucose and fructose — two sugar types that are ideal for athletic performance.

Bananas are also rich in potassium and magnesium , providing electrolytes to your body that — when lost — will cause muscle cramps and fatigue, so it's best to keep your levels topped-up.

Each banana will contain around g of carbohydrates, fuelling your muscles before strenuous exercise. Coconut Water: Like bananas, coconut water is naturally full of electrolytes.

With an improper electrolyte balance leading to muscle cramps, stiffness, nausea, headaches and fatigue, drinking coconut water will help top up your body's electrolyte supply.

I was happy that Ascent gave me the adequate amount of energy I needed to charge up my morning and workout. I've found that fruit-flavored pre-workouts can sometimes be filled with lots of artificial flavorings, which can taste too sweet.

This Beachbody pre-workout passed with flying colors. It doesn't have artificial flavors or sweeteners, which is helpful to know if you aren't a fan of most of the artificial sweeteners in pre-workouts.

I tried this pre-workout in the fruit punch flavor, and it was sweet without an unpleasant aftertaste. I had the individual packets, but Beachbody also sells 9.

This pre-workout consists of quercetin, which is a plant-based antioxidant that helps delay exercise-induced muscle fatigue to keep you going. It also contains mg of caffeine per serving and it should be noted that the directions say not to exceed two packets a day.

Ladder : This pre-workout was created with athletes in mind to make sure they perform to the best of their ability. It has caffeine, creatine, Beta-Alanine and L-Theanine. I tried the Tropical Fruit and Strawberry Lemonade flavors. Despite having no gastrointestinal issues, I wasn't a fan of the flavors and the aftertaste that lingered.

However, if I were to choose between the two, I would go with the Strawberry Lemonade because it had the better flavor profile. Coco5 : Although Coco5 is technically more of an electrolyte beverage, it is intended to be consumed during or after your workout to replenish electrolytes.

I liked the cherry flavor and that the coconut water flavor is not detectable. Coco5 didn't make the best list because the sugar content and calories were higher in comparison to Cure's and Nuun electrolyte powders.

Coco5's drinks are still lower in calories and sugar than traditional sports drinks, so it's a better choice if you had to pick between the two.

We acknowledge that everyone's body is different in the way they handle pre-workouts or any other supplement. Therefore, I used my own anecdotal experience as a fitness enthusiast and a recreational runner training for my next half-marathon to test and select the best pre-workouts.

These were exceptionally helpful on those days when I needed the extra boost to get me through my long runs or a strength training workout. When selecting the best pre-workout brands, I looked at:. Pre-workouts come in the form of a powder, are mixed with water and taken a half hour or up to an hour before a workout to help boost energy and performance.

Stimulants can raise your heart rate and blood pressure as well as increase nervous system activity. This will give you the peace of mind that the supplement you're taking is safe and free of banned substances.

Pre-workout, like any other supplement, is intended to be used in addition to a well-balanced diet and lifestyle. It should not be used as a treatment for any health concerns you may have. If you find yourself constantly lacking energy or if you have any other fitness-related health issues, you should discuss with your doctor before taking pre-workout or any new supplement to make sure you are a good candidate for it.

Side effects are one of the reasons some people are hesitant to take a pre-workout supplement. Some may be sensitive to caffeine, which is a key stimulant in many products, while others may not respond well to other ingredients such as artificial sweeteners or sugar alcohols.

Then there are those who have certain health conditions and are medically advised to avoid them altogether. You don't have to take a pre-workout supplement to perform well during a workout.

Some people say it gives them the extra pep they need, and studies have been promising so far. Generally pre-workouts are made up of multiple ingredients such as creatine, caffeine, amino acids, beta-alanine and other ingredients that provide energy or help with muscle recovery.

Many pre-workouts contain stimulants, which have always been a controversial topic in the fitness supplement industry because the US Anti-Doping Agency wants to keep certain illegal and potentially harmful ingredients off the market. Some pre-workouts on the market have been found to contain unsafe and untested stimulants.

If you have concerns about purchasing pre-workout, verify the product through a third party tested by a company such as NSF International , Informed Choice or Banned Substances Control Group. Wellness Fitness.

All workout-performance questions aside, safety is a big concern here since pre-workout supplements are not regulated by the U.

Food and Drug Administration FDA in the same way that drugs are. The only way to guarantee that a given product contains what it says it contains—and nothing it doesn't—is to find a product that is certified through a third-party regulatory body such as NSF or Informed Choice.

Both NSF and Informed Choice follow a strict vetting process to verify the quality and purity of supplements. Office of Dietary Supplements at the National Institutes of Health. Meanwhile, some of the ingredients that are safe in normal amounts can become harmful in the high concentrations found in supplements.

For example, some people experience increased heart rate and blood pressure, diarrhea, nausea, and jitters when they consume high amounts of caffeine, Fear says. For instance, a study in the Journal of Clinical Oncology found that long-term supplementation with high doses of vitamin B6 and B12 may significantly increase the risk of lung cancer in men; other studies have connected excessive beta-carotene intake to cancer and excess vitamin A to liver damage.

Ansari agrees that a food-first approach is best. For example, Crandall recommends fueling up for tough workouts with roughly 15 grams of carbohydrates—which you can get in half of a banana or one slice of bread with some jam.

Basically, before you start delving into pre-workout, make sure your basics are on point first, says Ansari.

If you want to try out pre-workout for yourself, you can give one of the options vetted by NSF or Informed Choice a shot. Make sure you stick to the serving size and take as directed.
