Discover the benefits of BCAAs: Boost your Performance and Sports Recovery!

BCAA benefits

What are BCAAs and What are Their Roles ?

There are around a hundred amino acids, but only 22 are encoded by our genetic material. Each of them plays a specific role in the order of protein assembly. Of these 22 amino acids, 9 are considered essential. "Essential' means that these molecules cannot be synthesised by the body. Among these, the BCAA s, or branched-chain amino acids, play a crucial role in protein structure.

Proteins are made up of a chain of amino acids, but they cannot be absorbed directly into the bloodstream in this complex form. They must first be broken down into individual amino acids, which can then cross the blood barrier.

However, there's an important detail to bear in mind: our bodies have the ability to synthesise and transform many amino acids into any other except the essential ones, among which are the BCAAs. So it's crucial to provide your body with the right amount of BCAAs according to your goals.

The effectiveness of BCAAs lies in the ratio between the three amino acids: leucine, isoleucine and valine. Let's say you make a balanced mix: for optimum results, you need two parts leucine to one part isoleucine and one part valine. This corresponds to the ratio 2.1.1. However, it is interesting to note that a ratio of 4.1.1 could be even more beneficial. On the other hand, according to some studies, a ratio of 8.1.1, does not seem to offer significant improvements.

Why Take BCAAs ? What are the benefits of BCAAs ?


BCAA s can act as an energy alternative to glycogen during exercise, extending the duration of your sessions and maintaining high intensity. They also limit the use of tryptophan, helping to increase alertness and reduce the feeling of fatigue.

Energy and fatigue are two key factors that determine the quality and intensity of your workouts. BCAAs aren't just muscle builders; they're also energy boosters. Let's find out how they help you stay energised and focused.

  • BCAAs and Muscle Energy:BCAAs play a direct role in energy production during exercise, particularly in endurance sports and high-intensity training.
  • Direct Energy Source for Muscles:
    • Muscle Energy: During exercise, BCAAs can be used directly by muscles as an energy source, which is particularly useful during long or intense workouts.
    • Glycogen Preservation: BCAAs help preserve muscle glycogen stores, the main source of energy during exercise, which helps prolong endurance.
  • Fatigue Reduction:
    • Decreased Serotonin Production: BCAAs can reduce the amount of tryptophan entering the brain, which decreases serotonin production. Serotonin is a neurotransmitter that plays a role in the feeling of fatigue.
    • Improved Mental Focus : By reducing fatigue, BCAAs also help maintain high mental focus during training.
  • Tips for Maximising Energy with BCAAs:
    • Timing: Take BCAAs before or during your workout to maximise energy levels and reduce fatigue.
    • Hydration : Drink enough water, as good hydration is essential to maintain energy levels.
    • Balanced Diet : Make sure you eat a balanced diet to support the effects of BCAAs and maintain optimal energy levels.

With BCAAs , you have a powerful ally to boost your energy and reduce fatigue, allowing you to push your limits with every workout. They're not just a supplement; they're fuel for your passion and determination.


BCAAs play a key role in muscle fiber repair, promoting faster recovery and more significant muscle gain.

Effective recovery allows the muscle to train more frequently and productively. The faster the fibres are repaired, the more the muscle will be able to resume profitable training and therefore the faster it will progress.

After intense training, muscle recovery is essential. BCAAs aren't just energy boosters during exercise; they're also recovery accelerators afterwards. Here's how they help you recover faster.

  • 1. Understanding Muscle Recovery:Muscle recovery is the process by which your muscles repair and strengthen after exercise. It's during this phase that you get stronger and your muscles grow.
  • 2. BCAAs and Protein Synthesis:
    • Stimulation of Protein Synthesis:BCAAs, particularly leucine, are known to stimulate muscle protein synthesis. This means they help your muscles repair and rebuild faster after training.
    • Reduce Muscle Damage:By increasing protein synthesis, BCAAs help reduce the extent of muscle damage caused by exercise, which can reduce muscle soreness and speed recovery.
  • 3. Fatigue Reduction:
    • Fatigue Reduction:BCAAs can reduce serotonin levels in the brain during exercise, reducing the perception of fatigue. This allows you to recover faster and feel ready for your next workout.
  • 4. Improved Resistance to Muscle Fatigue:
    • Muscular Endurance: By providing an extra source of energy during exercise, BCAAs help preserve muscle glycogen stores, which can improve endurance and reduce muscle fatigue.
  • 5. Tips for Maximising Recovery with BCAAs:
    • Timing: Take BCAAs before and after training to maximise muscle recovery.
    • Hydration: Drink enough water, as good hydration is essential for effective recovery.
    • Quality Sleep: Make sure you get plenty of sleep, as sleep is crucial for muscle recovery.

Don't forget, proper recovery is just as important as the training itself !


Another benefit of BCAAs is that if you suspend training due to injury or lack of time, increasing BCAA intake will minimise muscle loss.

Also, even without exercise, BCAAs stimulate protein synthesis in the muscles. Indeed, maintaining muscle tissue can boost metabolism and limit fat gain when you're not exercising. As a result, they therefore support both muscle growth and the maintenance of mass during prolonged phases of inactivity.

Injuries are part of the sporting journey, but how you manage your recovery can make all the difference. BCAAs aren't just useful for training; they're also crucial for supporting your body in the event of injury. Let's find out how.

BCAAs are essential for the repair and recovery of muscle tissue, which is particularly important in the event of injury.

  • Accelerating Muscle Repair:
    • Stimulating Protein Synthesis : BCAAs, in particular leucine, stimulate protein synthesis, a key process in the repair of damaged muscle tissue.
    • Reducing Healing Time : By speeding up muscle repair, BCAAs can help reduce the healing time needed after an injury.
  • Preventing Muscle Loss:
    • Maintaining Muscle Mass : When you're injured and less active, the risk of muscle loss increases. BCAAs help prevent this loss, preserving muscle mass even when physical activity is reduced.
  • Immune System Support:

    • Immune Strengthening: As mentioned above, BCAAs play a role in supporting the immune system, which is essential for a fast and effective recovery.
  • Fatigue Reduction:
    • Fatigue Management: BCAAs can help reduce the feeling of fatigue, an important aspect of staying positive and motivated during the recovery period.
  • Tips for Using BCAAs in Injury:
    • Consult a Professional: Before taking supplements, especially in the case of injury, consult a healthcare professional for suitable advice.
    • Appropriate Dosage : Follow dosage recommendations to maximise the benefits of BCAAs without overloading your body.
    • Alimentation and Hydration : Maintain a balanced diet and good hydration to support the healing process.

BCAAs are an invaluable support, not only for your training sessions, but also in difficult moments such as injuries. Recovery is an important process. Don't forget, each stage of recovery brings you closer to your return to strength.


BCAAs stimulate the production of antibodies and lymphocytes, helping to strengthen the immune system. When you're ill, and you're training, you weaken your body even more. BCAAs are therefore an important aid to faster recovery.

BCAAs are not just muscle builders; they are also vital for maintaining a strong immune system. Here's how:

  • Support for Immune Protein Synthesis:
    • White Blood Cell Production: BCAAs, particularly leucine, play a role in the production of white blood cells. These cells are essential for fighting infections and diseases.
    • Immune Response: Good availability of BCAAs aids in an effective immune response, allowing your body to react quickly and efficiently to threats.
  • Reduction of Stress and Inflammation:
    • Stress Management: Intense training can put your body in a state of stress, which can weaken your immune system. BCAAs help to reduce this stress, thus protecting your immunity.
    • Anti-Inflammatory: BCAAs have anti-inflammatory properties that can help reduce inflammation in the body, a key factor for a healthy immune system.
  • Improvement of Gut Health:
    • Good gut health is essential for a strong immune system. BCAAs can help maintain the integrity of the intestinal wall, thus promoting better overall health.
  • Tips for Optimizing the Immune Benefits of BCAAs:
    • Dosage and Timing: Consume BCAAs regularly, especially around your workouts, to maximize their impact on your immunity.
    • Balanced Diet: Combine BCAA intake with a nutrient-rich diet to support your immune system.
    • Rest and Recovery: Make sure to rest and recover properly after workouts to avoid overburdening your immune system.

BCAAs are more than just supplements for your muscles; they're an essential pillar in keeping your body fit and your immune system robust. A strong body starts with a strong immune system. Take care of yourself, and you'll be unstoppable !

BCAAs: A Key Asset in Fat Loss.

By promoting muscle growth, BCAAs have a direct impact on your basal metabolic rate. This translates into an increase in your body's energy expenditure. In other words, as your muscle mass increases, your calorie requirements increase to keep your body functioning properly. This dynamic creates an indirect opportunity to Burn fat .

During strict diet phases, BCAAs also play a crucial role in preserving muscle mass. This preservation is essential for maintaining a balanced body composition, which has a positive effect on your diet as a whole. In fact, maintaining your muscle mass helps to support your dietary efforts and helps to maintain a harmonious figure.

In short, BCAAs not only stimulate muscle growth, they also act as true guardians of your metabolism and body balance, particularly during periods of calorie restriction. Incorporating BCAAs into your routine can therefore prove to be a wise choice for lasting results.

Looking to sculpt your body by losing fat while preserving your precious muscle mass? BCAAs are your indispensable allies. Here's how they assist you in this quest.

  • 1. Understanding the Link Between BCAAs and Fat Loss:
    • BCAAs are not direct fat burners, but they play a crucial role in supporting fat loss, especially if you are in a period of caloric restriction or intense training.
  • 2. Muscle Mass Preservation: When you reduce your calories to lose fat, your body may also start to use muscles as an energy source, which is not ideal. BCAAs help prevent this by:
    • Protecting Muscles: They provide energy directly to muscles during training, thus reducing the need for the body to tap into muscle.
    • Stimulating Protein Synthesis: Even in a caloric deficit, BCAAs help maintain protein synthesis, essential for muscle preservation.
  • 3. Boosting Metabolism:
    • By helping to preserve muscle mass, BCAAs indirectly contribute to maintaining an active metabolism. The more muscle you have, the more calories your body burns at rest, thus facilitating fat loss.
  • 4. Reducing Fatigue and Improving Performance:
    • BCAAs can reduce fatigue during training, allowing you to train harder and longer. This translates to increased caloric expenditure, a key factor in fat loss.
  • 5. Tips for Maximizing the Effect of BCAAs on Fat Loss:
    • Timing: Consume BCAAs before or during your workout sessions to provide energy to your muscles and reduce fatigue.
    • Hydration: Drink enough water. Hydration is essential for optimizing metabolism and the effectiveness of BCAAs.
    • Balanced Diet: Combine BCAA intake with a balanced diet tailored to your fat loss goals.

BCAAs are more than just a supplement; they're a partner in your quest for a leaner, more toned body.


After intensive training, it is common to feel the after-effects in the form of muscle soreness, which often appears the next day or even the day after that. These muscular aches and pains can, however, be alleviated with an appropriate warm-up. BCAAs also have an important anti-catabolic effect. When you train, your body undergoes a destruction of muscle tissue, but rest assured, this is to rebuild it better afterwards. However, this training phase induces a powerful catabolic process which alters the muscle fibres. BCAAs intervene here by slowing down this degradation of muscle fibres, which helps to minimise the impact of the catabolic process. Muscle catabolism is a bit like your body deciding to 'eat' its own muscles, especially when you're in a calorie deficit or during very intense training. That's where BCAAs come in like real heroes.

  • 1. Understanding Muscle Catabolism: Catabolism is a natural process where the body breaks down muscle tissue for energy. This can occur during strict diets, prolonged fasting, or particularly exhausting workouts. As an athlete, you want to avoid this, as it can slow down your progress and decrease your strength.
  • 2. The Role of BCAAs in Preventing Catabolism: BCAAs, particularly leucine, play a crucial role in regulating protein metabolism. They help stimulate muscle protein synthesis, which is the muscle rebuilding process. But that's not all:
    • Anabolic Signaling: Leucine acts as a powerful signal to the body, indicating to start the muscle-building process. This helps counteract the catabolic effect.
    • Reducing Protein Breakdown: By providing an alternative energy source, BCAAs reduce the need for the body to break down muscle proteins, thus preserving your muscle mass.
  • 3. How to Optimize the Anti-Catabolic Effect of BCAAs:
    • Timing: Taking BCAAs before or during training can provide energy to muscles and reduce protein breakdown. After training, they aid in muscle recovery and repair.
    • Dosage: Following dosage recommendations is crucial. At QNT, we offer products with a perfect balance of BCAAs to maximize their beneficial effects.
    • Balanced Diet: BCAAs are even more effective when combined with a protein-rich and balanced diet.

By incorporating BCAAs into your routine, you offer your body protection against catabolism, ensuring that every training session brings you closer to your ideal shape.

BCAAs, For Whom and When ?

BCAA benefits

Insofar as BCAA s are useful and beneficial for intense training, it therefore seems important to keep some on hand before and during the session. And to recover better, afterwards too. All sportspeople who want to improve their performance can use BCAAs. BCAAs are very useful in high-intensity, short-duration and strength sports such as bodybuilding, because they help you recover better, reduce muscle breakdown and stimulate muscle building, but also in long-distance sports to provide alternative energy and enable you to maintain a high intensity for longer. Supplementing with BCAAs during a long-distance effort helps to reduce the breakdown of active muscles, minimise the degradation of glycogen stocks and reduce the phenomenon of central nervous fatigue.

BCAAs are a powerful tool in any sportsman's arsenal, but understanding who they're beneficial for and when to take them can make a big difference to your results. Here's how to optimise your use of BCAAs.
