They are perfect to be taken alongside post-workout supplements, ensuring the effort and time you put into the gym is not going to waste. Our ultra-convenient pre-workout snacks and ready-to-shake drinks have been tailored to help support your individual ambitions.

Most pre-workouts should be taken within 30 - 60 minutes of exercise. Bear in mind when you last ate can affect when you start to feel the effects of the pre-workout as that will slow down digestion and absorption.

How long a pre-workout lasts depends on how much caffeine and or other stimulants are within the product. The more stimulant, the longer it will last.

Most stimulants sustain their effect in some manner for four to six hours after consumption. A powder may be better if you struggle to adequately hydrate yourself as this will be a passive way to take in more fluid, however the choice really depends on personal preference.

Both would have similar effects, however a powder may also provide more rapid effects as it begins to absorb through receptors in the mouth. That depends on your tolerance, however research based effective dosages typically range from anywhere between to mg a serving.

One serving contains mg of caffeine per serving, plus 16 grams of carbohydrates, which are primarily from coconut palm sugar and brown rice syrup. Each serving contains the same amount of caffeine as a cup of home-brewed coffee — a smaller amount than is typical for pre-workout supplements. A single serving also contains sodium chloride, potassium, magnesium, and calcium — electrolytes that play a vital role in hydration 4.

In addition, a single serving contains 1. One serving contains 85 mg of caffeine per scoop in addition to a nitric oxide booster made of a combination of spinach, beet, and kale, all of which provide a source of dietary nitrates. Dietary nitrates are compounds that positively affect exercise performance when converted to nitric oxide after ingestion.

Nitric oxide has been found to increase blood flow to working muscles, improve oxygen efficiency during exercise, and reduce time to exhaustion 7 , 8.

This plant-based supplement also contains vitamins B12, C, and K and an antioxidant blend. Just keep in mind that this product contains erythritol, a sugar alcohol, which some people may prefer to avoid. One serving contains 5 grams of creatine, 1.

A single serving also includes 1 gram of taurine , an amino acid that may help reduce delayed onset muscle soreness This supplement is our top pick for focus because it also contains L-tyrosine , a nonessential amino acid that may have a positive effect on cognitive function 16 , One drawback is the higher dose of beta-alanine, which can cause a tingling sensation known as paraesthesia.

One flavor, Strawberry Lemonade, is also NSF Certified for Sport. One serving of this pre-workout contains mg of caffeine, 2. Beta-alanine has been found to affect muscle fatigue and improve strength performance when taken at the recommended dose of 4—6 grams per day for 2—4 weeks.

However, it can cause uncomfortable side effects in some people Gnarly Pre-Workout also contains citrulline malate, a compound that may have a positive effect on performance during high intensity exercise. Citrulline malate has been found to improve blood flow to working muscles while also reducing fatigue during high intensity exercise and strength training.

However, research is mixed regarding dose and effectiveness 18 , Ascent Pre-Workout is third-party tested and Informed Sport Certified. One serving contains mg of caffeine and 5 grams of protein from whey protein isolate. While the caffeine in this pre-workout does offer a performance boost, the minimal protein per serving is unlikely to affect performance or recovery.

However, the supplement can still contribute to total daily protein intake to support muscle protein synthesis 4 , 20 , 21 , With mg of caffeine per serving, Pre-Kaged is higher in caffeine than many other pre-workouts. Up to mg of caffeine per day has been found to be safe for consumption, with milligrams per kilogram of body weight providing a guide for customizing based on individual needs.

Research shows that 1. Pre-Kaged Pre-Workout also contains L-citrulline, BCAAs, beta-alanine, creatine HCL, and a proprietary blend of antioxidants. Vital Performance PRE is a pre-workout supplement in the sport-specific line of the Vital Proteins brand.

Pre-workout supplements can offer a variety of performance benefits, depending on their active ingredients and the amounts they contain.

Common ingredients in pre-workout supplements, such as caffeine, beta-alanine, and creatine, may have a positive effect on performance when taken in the amounts recommended in the research 28 , Research suggests that caffeine has an effect on perceived effort, beta-alanine has an effect on fatigue during high intensity exercise, and creatine contributes to increases in strength when taken over a period of time 12 , 23 , Additional pre-workout ingredients, such as tyrosine, may influence cognitive function, and others, such as nitrates, may have a positive effect on endurance 7 , 8 , For this reason, prioritizing diet and recovery before adding a pre-workout supplement is the most advantageous approach for performance.

Always talk with a sports dietitian or another healthcare professional before taking a supplement. Because pre-workout supplements vary in ingredient composition, it can be difficult to compare brands and dosages.

Knowing which ingredients impact performance can help you determine which supplement is best for you. Caffeine is a known central nervous stimulant that offers a performance benefit when taken prior to exercise.

Be sure to look for a pre-workout that contains the optimal caffeine dose according to research Beta-alanine is a nonessential amino acid that plays a role in buffering muscle pH during high intensity exercise such as sprinting. Nitrates are found in foods such as beets, celery, and leafy green vegetables like spinach.

Nitrates enhance performance by acting to dilate blood vessels and increase blood flow. Its effect is not as immediate as those of other compounds, such as caffeine. Research indicates that creatine monohydrate must be taken over a consistent period of time to have a performance benefit 11 , It will take, depending on the individual, about 30 days to saturate the muscles with a creatine dose of 3—5 grams daily.

Other ingredients, such as proprietary antioxidant blends, herbs, and high dose vitamins and minerals, require more research to confirm their effectiveness for supporting athletic performance. Potential side effects from pre-workout supplements depend on the ingredient types and amounts found in the supplement.

Some common ingredients can result in side effects that may be unpleasant for some people. Common ingredients in pre-workout supplements and their potential side effects are listed below. Pre-workout supplements may be appropriate for both untrained and trained people looking for a performance boost.

Ingredient formulations will greatly influence the effects of the pre-workout supplement. Pre-workout supplements often contain stimulants, such as caffeine, that may not be appropriate for some people. Anyone with a chronic health condition, such as heart disease or high blood pressure, and anyone who is pregnant or nursing should consult a sports dietitian or another healthcare professional before taking a pre-workout supplement.

Multi-ingredient pre-workout supplements have different ingredient amounts and variations that influence their effectiveness. Additionally, many pre-workout supplements include creatine in combination with other ingredients that also affect performance. Other pre-workout ingredients, such as caffeine and beta-alanine, can have more immediate effects.

This may make them more appropriate options for those who are looking for a performance boost after a single serving. Before adding a pre-workout supplement to your routine, consider your nutritional needs and fitness goals.

Optimal nutrition and improved fitness depend on a balanced diet that meets your individual needs. In addition to maintaining a nutritious diet, allowing enough time for recovery after workouts is essential. In humans, supplementation of 6 g of CM a day for 15 days led to a significant reduction in sensation of fatigue, an increase in the rate of oxidative ATP production during exercise, and an increase in post exercise recovery.

Citrulline malate is a non-essential amino acid part of the ureogenesis cycle. Excess availability of CM enables the acceleration of this cycle, thereby facilitating the clearance of ammonium from the blood and tissues, which is a major fatigue factor.

CM does so by stimulating glycolysis while blocking the aerobic utilization of pyruvate and recycling itself in the direction of gluconeogenesis. This results in less lactic acid accumulation and fatigue [2] , making it a perfect ingredient for your pre-workout.

Citrulline malate increases nitric oxide production and reduces muscular fatigue through the reduction of lactic acid and ammonia in blood and tissue. Citrulline malate has been shown to significantly increase performance during upper and lower body multiple bout resistance exercise performance.

Improves oxidative metabolism and exercise performance in healthy adults and enhances post exercise phosphocreatine recovery. On a total gram per day basis, beta-alanine dosing ranges from 2. Beta-Alanine is a non-essential amino acid synthesized in the liver and taken up into skeletal muscle to yield carnosine, a histidine containing dipeptide.

Carnosine acts as an intracellular hydrogen ion buffer to high intensity exercise, antioxidant and regulates muscle contractility.

In isolated muscle, the absence of carnosine as a buffering agent leads to fatigue due to increased acidosis. Therefore, high levels of skeletal muscle carnosine is positively associated with anaerobic exercise performance. Beta-Alanine improves muscle buffering capacity leading to improved resistance training quality by increasing the number of repetitions that can be performed at a given intensity of training.

Beta-alanine delays the onset of fatigue by reducing muscle acidosis. Increases peak power output in high intensity exercise. It is metabolized by the liver and through enzymatic actions resulting in several metabolites, including paraxanthine and theobromine.

Caffeine crosses the blood brain barrier with little difficulty resulting in a primary site of action in the central nervous system CNS by altering specific signaling pathways.

Caffeine use during exercise acts to decrease the body's reliance on glycogen utilization and increases its dependence on free fatty acid mobilization.

Additionally, caffeine supplementation increases serum beta-endorphin concentrations and leads to decreased pain perception.

Increases energy expenditure through its thermogenic stimulation. Enhances cognitive performance through increased vigilance and alertness. Rhodiola is a medicinal plant which contains adaptogenic and biologically active substances in its root, including flavonoids and phenolic glycosides.

An adaptogen is a natural herbal substance that helps the body adapt and resist damage caused by stress. Shown to reduce oxidative stress in blood, liver and skeletal muscle [11] animal study. Increases cognitive and neural performance [11] in healthy males. Increases overall health in mentally fatigued populations.

The amino acid L-3,4-dihydroxyphenylalanine L-DOPA is a metabolite of L-tyrosine and the precursor to dopamine. L-dopa crosses the blood brain barrier where it is synthesized to dopamine in the central and peripheral nervous systems. They are typically referred to as the dopa bean.

May improve cognitive function and mental alertness. This does really give me the energy I need to push myself through my workouts and challenge myself!

I had a lot of concerns with this product initially but customer service was amazing! Answered all my random questions and concerns which made me feel really good about my decisions with pur hazing this product. Plus it tastes amazing! Great stuff no fillers in here.

Do yourself a favor and give these products a shot. The pic attached to this review is me hyped up after a huge PR at a recent lift-off event! This is also going to sound like a paid endorsement because I love this stuff so much, but I have not been compensated in any way for the following feedback : I have been using this pre-workout for about 5 months now and cannot say enough about how thrilled I am to have found this product.

My strength, endurance, and mood are consistently and considerably better during my early morning workouts and I actually look forward to drinking this every morning! I know my own consistency and hard work accounts for some of my recent gains, but I have every confidence that the pre-workout has been giving me an edge as well.

Highly, highly recommend this product and have actually gotten several people at my gym to hop aboard and start it as well and they are enjoying similar results. THANK YOU, Outwork Nutrition! Love the short ingredient list. Feels, for lack of a better word, clean?

Like, I take it and I feel good as opposed to many preworkouts that bother my ol' tummy. And the effect of L-Dopa is noticeable. Creates a different feeling about what's going on. Bendahan, D, Mattei, JP, Ghattas, B, Confort-Gouny, S, Le Guern, ME, and Cozzone, PJ. Pérez-Guisado J, Jakeman PM.
