Should you, or should you not use a pre-workout supplement to aid in your workouts?  We will dive into what pre-workout supplement  are, and what are some of the common ingredients found in pre-workout drinks/supplements.

What is a Pre-Workout Supplement

Pre-workout supplements are a type of dietary supplement that are designed to boost energy and performance during exercise. They are often taken before a workout to help increase focus, endurance, and strength, and can be especially beneficial for high-intensity exercises such as weight lifting or interval training. Pre-workout supplements usually contain a combination of ingredients such as caffeine, amino acids, and creatine, which can help to improve physical and cognitive function. Some pre-workout supplements also contain nitric oxide boosters, which can help to improve blood flow and oxygen delivery to the muscles, as well as branched-chain amino acids (BCAAs), which can help to reduce muscle breakdown and promote muscle growth.

It’s important to note that not all pre-workout supplements are created equal, and some may contain ingredients that are not well-studied or may have negative side effects. It’s always a good idea to speak with a healthcare provider or a sports nutritionist before starting any new supplement regimen. Additionally, it’s important to remember that pre-workout supplements should be used in addition to, not in place of, a healthy diet and regular physical activity. A well-balanced diet and regular exercise are essential for optimal health and performance, and can provide many of the same benefits as pre-workout supplements.

Common Pre-Workout Ingredients


Caffeine is a stimulant that can help to improve focus and alertness, as well as increase endurance and strength. It works by stimulating the central nervous system and increasing the release of neurotransmitters such as dopamine and norepinephrine, which can improve mood and cognitive function. Caffeine is also a thermogenic, meaning that it can increase the body’s metabolic rate and help to burn more calories. The optimal dose of caffeine for improving exercise performance is usually around 3-6 mg/kg of body weight. Caffeine can also help to reduce muscle pain and fatigue during exercise, and may even enhance fat oxidation.


Beta-alanine is an amino acid that helps to improve muscle endurance and reduce fatigue. It works by increasing the production of carnosine, a compound that helps to buffer lactic acid in the muscles, which can help to delay fatigue during exercise. Beta-alanine is thought to be most effective when taken in doses of 3-6 grams per day, and can be especially beneficial for high-intensity exercises such as sprinting or weight lifting. Beta-alanine may also help to improve muscle function and reduce muscle damage, and may even have some anti-aging effects.


Creatine is a compound that is produced naturally in the body and is also found in some foods such as meat and fish. It helps to increase strength and power output, and can also improve recovery time after exercise. Creatine works by increasing the production of ATP (adenosine triphosphate), which is the primary source of energy for muscle contractions. It is typically taken in doses of 3-5 grams per day, and is most effective when taken consistently over a period of several weeks. Creatine may also help to improve muscle mass and function, and may even have some cognitive benefits.

Nitric Oxide Boosters

Nitric oxide is a molecule that helps to relax blood vessels and improve blood flow. Some pre-workout supplements contain ingredients such as arginine and citrulline, which can help to boost nitric oxide production and improve performance. Nitric oxide supplements are thought to be most effective when taken in doses of 3-6 grams per day, and may be especially beneficial for endurance athletes. Nitric oxide can help to increase blood flow to the muscles, which can improve oxygen delivery and nutrient uptake, and may also help to reduce fatigue. Nitric oxide may also have some cardiovascular benefits, and may even help to reduce blood pressure.

Branched-Chain Amino Acids (BCAAs)

BCAAs are a group of amino acids that are important for muscle growth and recovery. They can help to reduce muscle soreness and fatigue, and may also improve exercise performance. BCAAs are typically taken in doses of 2-5 grams per day, and are often used before or after exercise to help with muscle recovery. BCAAs can help to reduce muscle breakdown during exercise and may also stimulate protein synthesis, which can help to promote muscle growth and repair. BCAAs may also help to improve immune function and may even have some anti-inflammatory effects.

Wrap Up

There you have it, the most common pre-workout ingredients.  In a follow up article, we will be diving into some of the popular pre-workout supplements on the market.  Should you take a pre-workout?  Generally YES.  The stimulant effect alone of caffeine, as well as the endurance effect that can be felt from beta-alanine can be a significant boost to your workouts.  Creative is also a must have for those serious about putting on lean muscle mass.  In many pre-workouts, the amount if creative is insignificant, and a separate creative monohydrate supplement will most likely be needed.
