Branch Chain Amino Acids (BCAAs) are the building blocks of protein, which stimulate your body to rebuild and grow new muscle tissue. 

They’re also crucial for overall health and well-being and play a vital role in muscle growth, tissue repair, enzyme production, and the maintenance of healthy immune function. Essential amino acids are particularly important as they support muscle protein synthesis, which is crucial for muscle repair and growth.

Amino acid supplementation can ensure you have the optimal amount of BCAAs needed to maintain health and fuel your muscle growth. 

Nine essential amino acids are not naturally synthesised in the human body and need to be obtained through our diets. Amino acid supplements are the easiest way to ensure you’re getting enough essential amino acids to support your fitness and bodybuilding goals.

  • Histidine
  • Isoleucine
  • Leucine
  • Lysine
  • Methionine
  • Phenylalanine
  • Threonine
  • Tryptophan
  • Valine

Of the nine essential amino acids, three are responsible for maintaining muscle mass and repairing broken-down muscle tissue:

  • Isoleucine
  • Valine
  • Leucine

Isoleucine is a branched-chain amino acid (BCAA) essential for the synthesis of haemoglobin, regulating blood sugar levels, and repairing muscle tissue. It also contributes to energy regulation within the body, making it an important component of endurance and physical performance. Isoleucine is particularly beneficial for promoting muscle recovery after intense workouts, aiding in the maintenance and growth of lean muscle mass.

Valine is vital for maintaining and repairing muscle tissue, making it essential for muscle metabolism and tissue repair. It also plays a key role in energy production and regulating the body's nitrogen balance. Valine supports muscle growth and repair, enhances endurance, and aids in the maintenance of overall physical performance. 

Leucine is the primary BCAA that stimulates protein synthesis and prevents muscle catabolism. You'll notice that BCAA products have a higher ratio of leucine to isoleucine and valine in their mixtures to activate mTOR signalling and amp up the muscle-building and recovery process. MAX'S BCAA 10:1:1, for example, has a high-leucine formulation for maximising energy, boosting recovery and promoting protein synthesis.


There's a reason why amino acids are so popular— it's because of the massive benefits they offer, regardless of your fitness goals. BCAAs can help you:

  • Build muscle. BCAAs help build muscle by providing essential amino acids necessary for muscle protein synthesis, supporting the development of lean muscle mass.
  • Accelerate the rate of protein synthesis. BCAAs accelerate the rate of protein synthesis, aiding in enhanced muscle recovery and growth, which is particularly beneficial for individuals engaged in rigorous training or seeking to optimise muscle-building potential.
  • Slow down protein breakdown. BCAAs slow down protein breakdown, helping preserve existing muscle mass and minimise muscle loss, especially during calorie restriction or intense training. 
  • Reduce fatigue, thereby enhancing workout intensity. BCAAs reduce fatigue, enhancing workout intensity and endurance by mitigating the onset of fatigue during physical activity, leading to more productive training sessions.
  • Improve mental focus. BCAAs improve mental focus by reducing the perception of effort during exercise, allowing individuals to maintain concentration and performance throughout their workouts.
  • Increase muscle retention. BCAAs increase muscle retention, aiding in preserving hard-earned muscle mass, which is particularly valuable for individuals aiming to optimise body composition and reduce body fat levels. 
  • Burn more fat, especially when combined with glutamine. BCAAs can burn more fat, especially when combined with glutamine, making them a valuable supplement for individuals seeking to enhance fat-burning potential and improve body composition.
  • Decrease delayed onset muscle soreness (DOMS). BCAAs decrease delayed onset muscle soreness (DOMS) following intense exercise, supporting muscle recovery and repair to help alleviate discomfort and aid in quicker recovery.


Yes, branched-chain amino acids (BCAAs) such as leucine, isoleucine, and valine are especially beneficial for muscle health, recovery, and performance. The right combination of protein and amino acids, along with other supplements, can help to accelerate muscle growth and aid recovery for maximum results. 

Amino acid supplements can be beneficial when taken before, during, or after workouts to support muscle recovery and growth. Pre-workout supplementation provides essential amino acids to aid in muscle protein synthesis, while during and post-workout intake can help prevent muscle breakdown and facilitate post-exercise recovery. 

Non-essential amino acids are those that the body can produce on its own and are not required to be obtained through the diet. These amino acids include alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine. While they are termed "non-essential," they still support various bodily functions and overall health.

Foods that contain high amounts of amino acids include:

  • Lean Meats: Chicken, turkey lean cuts of beef and other animal proteins are rich sources of amino acids, particularly essential ones like leucine, isoleucine, and valine.
  • Fish: Salmon, tuna, and other fatty fish are excellent sources of essential amino acids, including omega-3 fatty acids.
  • Eggs: Egg whites are a complete protein source, providing all essential amino acids in high amounts.
  • Dairy Products: Milk, yoghurt, and cheese are rich in essential amino acids, particularly whey and casein proteins.
  • Plant-Based Sources: Quinoa, tofu, soybeans, and legumes such as lentils and chickpeas are good vegetarian sources of essential amino acids.
  • Nuts and Seeds: Almonds, chia seeds, flaxseeds, and pumpkin seeds are high in essential amino acids and healthy fats.

Many people find it difficult to obtain enough amino acids through diet alone and opt for high-quality supplements.
