Brief
BCAA (Branched-Chain Amino Acids) refers to a group of three essential amino acids — L-Leucine (CAS No. 61-90-5), L-Isoleucine (CAS No. 73-32-5), and L-Valine (CAS No. 72-18-4). These amino acids are called “branched-chain” due to their unique chemical structure, which supports muscle protein synthesis, energy production, and recovery. BCAAs are widely used in sports nutrition, dietary supplements, and medical nutrition to enhance performance and prevent muscle fatigue.
What is BCAA?
BCAAs are essential nutrients that the body cannot synthesize on its own — they must be obtained from diet or supplementation. Together, these three amino acids make up nearly 35% of the amino acids in muscle protein and play a critical role in muscle growth and repair.
- L-Leucine: Stimulates muscle protein synthesis and acts as the key anabolic signal.
- L-Isoleucine: Supports energy regulation and glucose uptake into muscles.
- L-Valine: Aids in tissue repair and prevents muscle breakdown during exercise.
BCAA supplements are commonly consumed before, during, or after workouts to promote recovery and endurance.

What does BCAA do?
Key Benefits and Functions:
- Muscle growth and repair – BCAAs, especially leucine, trigger mTOR signaling to promote protein synthesis.
- Exercise performance – provide energy during intense training and delay fatigue.
- Reduce muscle soreness – help lower muscle damage markers like creatine kinase.
- Prevent muscle catabolism – preserve lean mass during fasting, calorie restriction, or endurance exercise.
- Mental focus support – regulate neurotransmitters such as serotonin to reduce central fatigue.
Applications:
- Sports and fitness supplements (powders, capsules, beverages)
- Medical nutrition for muscle maintenance and recovery
- Dietary fortification in protein shakes and energy drinks
Conclusion
BCAAs are essential amino acids that play a vital role in muscle recovery, endurance, and energy metabolism. Whether you are an athlete, fitness enthusiast, or recovering from physical stress, BCAA supplementation helps reduce fatigue, improve recovery, and preserve lean muscle mass. As a cornerstone of sports nutrition, BCAAs remain one of the most trusted and effective ingredients for promoting muscle performance and resilience.
