Pre-Workout
Pre-workout is a training supplement taken before exercise to increase energy, focus, and pump. Typically contains caffeine, beta-alanine, citrulline, and creatine.
What is Pre-Workout?
Pre-workout is a training supplement used by many as part of their preparation before exercise. These supplements are designed to increase energy, focus, and muscle pump, which can contribute to a more intense and effective training session. The most common ingredients in pre-workout products include caffeine, beta-alanine, citrulline, and creatine. By taking pre-workout before training, one can maximise performance and reach training goals faster.
How does it work in the body?
Pre-workout works by affecting several physiological processes in the body. Here are some of the key mechanisms:
- Caffeine: One of the most popular ingredients in pre-workout is caffeine, which acts as a central nervous system stimulant. It increases alertness, reduces fatigue, and can improve physical performance by raising adrenaline levels.
- Beta-alanine: This amino acid helps increase muscle capacity by reducing lactic acid build-up, allowing you to train longer and harder.
- Citrulline: Citrulline is an amino acid that has been shown to increase blood flow and thereby muscle pump during exercise, which can lead to better performance.
- Creatine: Creatine is a natural substance found in the body that helps produce ATP, the energy used by muscles during high-intensity training.
Scientific benefits
Several studies have examined the effect of pre-workout supplements on performance. Here are some scientifically supported benefits:
- Increased endurance: A study published in the Journal of the International Society of Sports Nutrition showed that supplements containing beta-alanine can increase endurance during high-intensity training.
- Improved strength: Another study showed that caffeine can increase maximal strength and power during lifting, making it a popular ingredient in pre-workout products.
- Increased blood flow: Research has also shown that citrulline can improve blood flow to muscles, which is important for muscle pump and oxygen delivery during exercise.
Dosage and recommendations
The dosage of pre-workout can vary depending on the product and individual tolerance. Here are some general recommendations:
- It is common to take pre-workout 20-30 minutes before training.
- Start with a smaller dose to see how your body reacts, especially if you are sensitive to caffeine.
- Do not exceed the recommended dose stated on the product label.
Best sources and forms
Pre-workout supplements come in various forms, including powders, capsules, and ready-to-drink beverages. Powder is the most popular option as it allows for dose adjustment. Always ensure to choose products from reliable manufacturers and check the ingredient list to ensure you get a quality product.
Side effects and warnings
Despite the many benefits, pre-workout supplements can cause side effects, especially if taken in excessive doses. Common side effects include:
- Headache
- Nausea
- Increased heart rate
- Sleep disturbances, especially if taken late in the day
It is important to consult a doctor before starting pre-workout, especially if you have underlying health conditions or are taking other medications.
Frequently asked questions
Is pre-workout safe to use?
Yes, pre-workout is generally safe for healthy individuals when used according to recommendations. However, it is important to be aware of your own tolerance and any underlying health issues.
Can I take pre-workout every day?
It is not recommended to use pre-workout every day to avoid developing tolerance to ingredients like caffeine. It is best used as needed, for example before intense training sessions.
What is the best time of day to take pre-workout?
Most recommend taking pre-workout 20-30 minutes before training to maximise its effects.
What should I do if I experience side effects?
If you experience side effects, you should stop using the product and consult a doctor for advice.
Is it possible to combine pre-workout with other supplements?
Yes, many combine pre-workout with other supplements such as proteins or amino acids. However, be cautious about total caffeine and stimulant intake.

Caffeine
The world's most consumed stimulant. Enhances performance, focus, and fat burning through adenosine receptor blockade.
Beta-Alanine
Amino acid that increases muscle carnosine levels and delays fatigue during intense exercise. Produces a characteristic tingling sensation.
L-Citrulline
L-citrulline is an amino acid that is converted to L-arginine in the kidneys and increases nitric oxide production. More effective than arginine itself for vasodilation.
Creatine
Creatine is a naturally occurring substance stored in muscles and used as a quick energy source during intense physical activity. It is the most studied and proven sports supplement for strength and muscle building.
