There is no universal formula for what a pre-exercise supplement should contain. The ingredients vary in type and quantity depending on the product. Typically, these supplements feature caffeine as a key component, along with a blend of other substances such as creatine, amino acids, and essential nutrients.

What is a Pre-Workout Supplement?

A pre-workout supplement is a formulation designed for consumption before training. It includes ingredients that help support muscle growth, boost muscular strength, enhance power and stamina, and sharpen mental concentration.

This supplement is commonly available in powder or liquid form, though pre-workout capsules and bars are also alternatives. The two primary categories of pre-workout supplements are stimulant-based (containing caffeine) and non-stimulant (caffeine-free).

Why are Pre-Workout Supplements Important?

Pre-workout supplements play a crucial role as they are designed to be consumed before exercise to boost concentration and energy while also supporting muscle growth.

Wisconsin-based sports nutritionist Abby Olcott, MS, RDN, states,

A pre-workout supplement can be beneficial in providing the body with the added ability to train harder and extend workout duration, enhancing the progress and adaptations achieved from those sessions.

How We Researched and Selected the Pre-Workout Supplements

We assessed third-party verified, multi-ingredient pre-workout supplements individually and compared their components with existing research to validate their effectiveness.

Given the variations among brands, we considered the following factors to determine which supplements made the cut:

• Quality: The integrity of a supplement is ensured through third-party verification, which confirms that the product contains the active ingredients stated on the label. All pre-workout supplements included here have undergone independent testing.
• Active Ingredients: We selected pre-workout supplements featuring scientifically supported ingredients known to enhance performance. Since formulations differ, it’s essential to evaluate your personal needs before incorporating a supplement into your regimen.
• Allergens: Some pre-workout supplements may contain one or more of the eight primary allergens. We highlight allergen disclosures where relevant, but if you have allergies, always review the product label carefully.
• Price: The cost of pre-workout supplements varies. To assist you in making a cost-effective decision, we’ve included a pricing guide below.

How To Choose the Best Pre-Workout Supplements?

Key Ingredients: Choose formulas that include research-supported ingredients such as caffeine, citrulline, beta-alanine, and creatine. Studies indicate these compounds can enhance energy, strength, and endurance while minimizing fatigue.

Optimal Dosages: The effectiveness of key ingredients depends on their dosage. Ensure the supplement provides scientifically recommended amounts, such as 200mg of caffeine, 5g of creatine, 6g of citrulline, and 3g of beta-alanine, to maximize benefits.

Clear Labeling: Steer clear of proprietary blends that conceal ingredient quantities. A transparent label listing each component and its exact amount allows for a better evaluation of the supplement’s effectiveness.

Quality Control: Opt for supplements that have been independently tested for purity and potency. Certifications from organizations like NSF or Informed-Sport indicate that the product has passed rigorous third-party testing.

Athletic Compliance: If you’re an athlete, ensure the supplement won’t lead to a failed drug test. Use online databases to verify ingredients against banned substance lists for your specific sport.

Common Ingredients Present in Pre-Workout Supplements

Creatine

Creatine is an amino acid that aids in protein synthesis within the body. These proteins contribute to the repair of damaged tissues and support overall bone and muscle health.

The Journal of the International Society of Sports Nutrition highlights that supplementing with creatine when paired with intense resistance training, may help boost fat-free mass, physical strength, and muscle structure.^[2]

Beta-Alanine

Beta-alanine is associated with increased endurance, benefiting both cardio-based intervals and high-rep strength training (lasting between 60 and 120 seconds of continuous effort). It is also known to cause a tingling sensation (paresthesia) in the extremities. By enhancing endurance, it may aid in muscle growth (hypertrophy).

A study conducted by R. M. Hobson and published in the Amino Acids journal notes that beta-alanine supplementation has gained popularity in the field of sports nutrition.^[3]

Taurine

Taurine: is believed to improve mental focus. Additionally, since it helps draw water into cells, it may assist in muscle recovery and reduce cramping. It is recommended to take up to six grams per day, ideally one to two hours before training.

According to the Antioxidants journal, taurine contains high levels of antioxidants, which may aid in muscle recovery post-exercise and help decrease muscle fatigue.^[4]

Benefits of Pre-Workout Supplements

Enhance Anaerobic Performance: Most pre-workout supplements include caffeine, a potent stimulant associated with increased endurance, strength, cognitive function, power output, and reduced perception of effort.

Increase Physical Stamina: Pre-workout supplements also feature powerful compounds such as L-citrulline, betaine, beta-alanine, and tyrosine, which help enhance endurance, promote better blood circulation, elevate energy levels, and enable you to perform at peak capacity.

Build Muscle Strength: Betaine, a key ingredient in many pre-workout supplements, may aid in improving body composition, stimulating muscle growth, and enhancing both muscle strength and endurance.

Support Testosterone Production: Certain pre-workout formulas contain herbal extracts like Tribulus Terrestris, ashwagandha, and black pepper, which may contribute to elevated testosterone levels, increased muscle endurance, and improved energy levels.

Are Pre-Workout Supplements Safe to Use?

Pre-workout supplements are generally safe when used as directed, but their safety depends on the ingredients, dosage, and individual tolerance. Many contain stimulants like caffeine, which can enhance energy and focus but may cause jitters, insomnia, or increased heart rate in sensitive individuals.

Other common ingredients, such as beta-alanine and niacin, may lead to harmless side effects like tingling sensations or skin flushing. To ensure safety, it’s best to choose supplements that have undergone third-party testing for purity and quality, such as those certified by NSF or Informed-Sport.

Individuals with underlying health conditions, such as heart disease or high blood pressure, should consult a healthcare professional before using pre-workouts. Additionally, starting with a lower dose can help assess tolerance. When taken responsibly, pre-workout supplements can be a valuable tool for enhancing performance and endurance.

Potential Side Effects of Pre-Workout Supplements

The side effects of pre-workout supplements vary depending on the type and amount of ingredients they contain.

Certain ingredients may cause discomfort for some individuals. Below are common components found in pre-workout supplements along with their possible side effects:

• Caffeine: Potential side effects include headaches, digestive issues, rapid heartbeat, anxiety, and trouble sleeping.
• Beta-Alanine: High doses may cause a tingling sensation (paresthesia), which some individuals find uncomfortable.
• Citrulline Malate: This may lead to digestive disturbances in sensitive individuals.
• Creatine Monohydrate: This can cause temporary water retention, leading to slight weight gain or bloating.

Do Pre-Workout Supplements Work?

Pre-workout supplements can be effective, but their impact depends on the ingredients and individual response. Many contain scientifically backed compounds like caffeine, beta-alanine, citrulline, and creatine, which can enhance energy, endurance, and muscle performance.

Caffeine is a well-known stimulant that improves focus, alertness, and power output, while beta-alanine helps delay muscle fatigue, allowing for longer and more intense workouts. Citrulline malate supports better blood flow, reducing muscle soreness, and creatine enhances strength and muscle recovery.

However, the effectiveness of pre-workouts varies by formulation and personal tolerance. Some people may experience noticeable benefits, while others might not see significant improvements. It’s also important to use them in combination with proper nutrition, hydration, and training.

Ultimately, pre-workout supplements can provide a performance boost, but they are not a substitute for a well-balanced fitness regimen. Choosing high-quality, research-backed supplements is key to maximizing benefits.

How do Pre-Workout Supplements Work?

The most effective pre-workout supplements combine key ingredients such as beta-alanine, betaine, citrulline, and carnitine, which work synergistically to enhance muscle growth, increase strength, boost endurance, and support faster recovery.

Dr. Elena Klimenko explains,

Pre-workout supplements designed to enhance athletic performance and provide an additional energy boost during exercise have gained popularity among gym enthusiasts, athletes, bodybuilders, and trainers.

Many pre-workout formulas also contain caffeine, a natural stimulant that enhances mental focus and alertness, helping individuals stay engaged and motivated during training.

According to a study by Amit Batra, Piotr Kaczka, et al., published in the International Journal of Environmental Research and Public Health, high-quality pre- and post-workout supplements can improve reaction time, enhance muscle strength, and optimize physical performance, particularly in trained individuals.^[5]

When combined with proper hydration and nutrition, pre-workout supplements can be a valuable tool in maximizing workout efficiency and results.

When and How to Take Pre-Workout Supplements for Best Results?

It’s crucial to consult your doctor or a nutritionist before using any pre-workout supplements.
Once you get the go-ahead, begin with no more than half a dose to gauge your personal tolerance. Consuming excessive amounts may lead to restlessness, tingling sensations, headaches, dehydration, or an upset stomach. To prevent these side effects, start with a smaller quantity and observe how your body reacts.

Besides easing into it, make sure to drink sufficient water throughout your workout to remain hydrated.

Lastly, try to avoid taking pre-workouts too late in the day. The high caffeine levels can interfere with your sleep, so if you exercise in the evening, consider a stimulant-free pre-workout to avoid sleeplessness.

Who Should Consider Using Pre-Workout Supplements?

Pre-workout supplements can be beneficial for both beginners and experienced individuals who are seeking to enhance their workout performance. The specific ingredients in the supplement play a crucial role in determining its effectiveness and the desired outcomes, such as increased energy, improved endurance, and better focus.

If you’re considering incorporating a pre-workout into your routine, it’s essential to carefully assess the available products based on your personal fitness goals and health condition.

Always check the ingredient list to ensure it aligns with your needs, and consult with a healthcare professional or nutritionist before starting a new supplement. This will help ensure that the supplement is safe, and appropriate for your body, and will help you achieve the desired improvements in your training sessions.

Who Should Stay Away from Pre-Workout Supplements?

Pre-workout supplements typically include stimulants like caffeine, which may not be suitable for everyone.

Individuals with chronic health conditions, such as cardiovascular issues or hypertension, as well as those who are pregnant or breastfeeding, should seek advice from a sports nutritionist or healthcare provider before using a pre-workout supplement.
