Pre-Workout Nutrition: Stay Energised and Optimise Performance

Pre-workout nutrition, for me, is a cornerstone element when it comes to optimizing performance and attaining fitness goals. I think a lot about food and basically want to eat everything I set my eyes on, however, I have learnt to control when, where and what I eat, particularly prior to exercise. Whether you are an avid athlete or a casual gym-goer, understanding the significance of properly fuelling your body before exercise is essential in reaching your full potential. This short blog aims to shed light on the importance of pre-workout nutrition, whilst also offering valuable insights into the various aspects and benefits of incorporating supplements into your routine. I will go into much greater depth around the subject of specific supplements in the very near future, so stay tuned.

Fuelling the Body for Success:

To perform at your best, it is crucial to consume a balanced meal approximately 2-3 hours before your workout. This meal should include carbohydrates, protein, and healthy fats. Not only does this provide the necessary energy, but it also helps sustain endurance and aids in muscle recovery post-workout (1).

Snacking for Quick Energy:

In situations where time is limited, a smaller snack 30-60 minutes before your workout can provide the necessary fuel. This snack should consist of easily digestible carbohydrates and some protein. Examples include a banana with peanut butter or a protein shake (1).

The Benefits of Caffeine:

Caffeine has become a popular pre-workout supplement due to its ability to enhance focus and increase energy levels. Studies have shown that caffeine improves physical performance by reducing fatigue and enhancing endurance (2). However, caution should be exercised when using pre-workout supplements containing stimulants, and it is advisable to consult a healthcare professional beforehand (3).

The Importance of Hydration:

Proper hydration is critical for optimal performance during exercise. It is recommended to consume plenty of water before a workout to ensure the body is well-hydrated. This helps regulate body temperature, lubricate joints, and transport nutrients to muscles more efficiently (2).

Listening to Your Body:

It is essential to listen to your body and adjust pre-workout nutrition based on personal preferences and goals. Everyone's dietary needs and tolerance to supplements may vary. Experiment with different approaches and find what works best for your body (2).


Creatine, NO2 Boosters, Taurine, BCAAs, and B Vitamins:


Creatine is a popular supplement used to enhance muscle strength and power during high-intensity exercises. It works by providing extra energy to the muscles, allowing for increased performance (1,3,4).

  • Creatine is a naturally occurring compound found in the body, and it is also available as a supplement.

  • The body produces creatine naturally in small amounts, mainly in the liver, kidneys, and pancreas.

  • Additional supplementation of creatine is often needed because the body's natural production may not be sufficient to meet the demands during high-intensity exercises.

  • Creatine works by increasing the levels of phosphocreatine in the muscles, which can then be used as a rapid source of energy during intense physical activities.

  • This increased energy availability leads to improved muscle performance, strength, and power.

Pros: Enhances muscle strength and power; improves performance during high-intensity exercises.

Cons: May cause weight gain due to water retention; potential gastrointestinal side effects.

-NO2 Boosters:

Nitric oxide (NO2) boosters are commonly used to enhance blood flow and improve nutrient delivery to muscles. This can lead to increased endurance and reduced fatigue during workouts (1,5,6).

  • NO2 boosters are supplements that aim to increase the production and availability of nitric oxide in the body.

  • Nitric oxide is a naturally occurring molecule that plays a crucial role in vasodilation, or the widening of blood vessels.

  • The body produces nitric oxide naturally, but additional supplementation can help enhance its effects for improved blood flow and nutrient delivery to muscles.

  • Increased blood flow can lead to improved endurance, reduced fatigue, and enhanced performance during workouts.

Pros: Enhances blood flow and nutrient delivery to muscles; improves endurance and reduces fatigue.

Cons: Potential side effects such as headache, nausea, and dizziness; limited evidence on long-term effects.


Taurine is an amino acid or type of protein that has been shown to improve exercise performance by reducing muscle damage and fatigue. It has favorable antioxidant and anti-inflammatory properties, helps regulate blood pressure and improves heart function. (1,7,8).

  • Taurine is an amino acid that is naturally produced in the body and can also be obtained through dietary sources, such as, Beef, Chicken, Eggs and Fish.

  • The body produces taurine naturally in various organs, including the brain, heart, and muscles.

  • However, additional supplementation of taurine may be necessary to meet the increased demands during exercise.

  • Taurine has been shown to have multiple benefits, including reducing muscle damage and fatigue, regulating blood pressure, improving heart function, and potentially enhancing endurance and recovery.

Pros: Reduces muscle damage and fatigue; regulates blood pressure; improves heart function.

Cons: Limited evidence on long-term safety; potential interactions with certain medications.

-BCAAs (Branched-Chain Amino Acids):

BCAAs are essential amino acids that play a crucial role in muscle protein synthesis and reducing muscle protein breakdown during intense exercise. They can also help reduce exercise-induced muscle soreness (1, 9, 10).

  • BCAAs are a group of essential amino acids, including leucine, isoleucine, and valine.

  • These amino acids cannot be produced by the body and must be obtained through dietary sources or supplementation.

  • BCAAs play a crucial role in muscle protein synthesis, which is the process of building new muscle proteins.

  • During intense exercise, BCAAs can also help reduce muscle protein breakdown and alleviate exercise-induced muscle soreness.

Pros: Facilitates muscle protein synthesis; reduces muscle protein breakdown; alleviates exercise-induced muscle soreness.

Cons: Limited evidence on performance enhancement; potential gastrointestinal side effects.

B Vitamins:

B vitamins, such as B6 and B12, are involved in energy production and metabolism. Supplementation with B vitamins can help optimize energy levels and enhance performance (2, 11, 12).

  • B vitamins, such as B6 and B12, are crucial for energy production and metabolism in the body.

  • These vitamins are involved in various metabolic processes, including the breakdown of carbohydrates, fats, and proteins for energy.

  • Supplementation with B vitamins can help optimise energy levels and enhance performance, particularly during periods of increased physical activity.

Pros: Optimises energy levels; enhances performance; supports metabolism.

Cons: Limited evidence on performance enhancement in individuals with adequate dietary intake; potential interactions with certain medications

Supplements have been found to offer a range of mechanisms of action that can potentially enhance exercise performance and overall health. Their benefits can be substantial, but it is crucial to approach supplementation with careful consideration of individual needs and potential side effects. Before embarking on any supplementation regimen, it may be advisable to consult with a qualified healthcare professional.

Bottom Line and conclusion

Fuelling your body properly before a workout significantly impacts your performance and helps you achieve your fitness goals. Remember to consume a balanced meal or a small snack depending on the time available. Hydration and personalization are also key factors to optimize performance. Consider the benefits and potential side effects of pre-workout supplements containing stimulants, and always consult a healthcare professional if you are unsure or worried in any way.
