BCAA vs EAA - What's the Difference?
Amino acids are the building blocks of proteins. But should you choose BCAA or EAA? Let us explain.
What is BCAA?
BCAA (Branched-Chain Amino Acids) are 3 branched-chain amino acids:
- Leucine - main muscle synthesis trigger
- Isoleucine - energy and recovery
- Valine - muscle protection
Typical ratio: 2:1:1 (leucine:isoleucine:valine)
What is EAA?
EAA (Essential Amino Acids) are all 9 essential amino acids:
- 3 BCAAs (leucine, isoleucine, valine)
- + 6 additional: histidine, lysine, methionine, phenylalanine, threonine, tryptophan
Comparison
| Feature | BCAA | EAA |
|---|---|---|
| Amino acid count | 3 | 9 |
| Complete protein synthesis | No | Yes |
| Price | Cheaper | More expensive |
| Calories | ~15 kcal | ~20 kcal |
| Taste | Better | Can be bitter |
When to Choose BCAA?
- When you get enough protein from food (1.6+ g/kg)
- Training fasted for energy
- When you prefer better taste
- On a limited budget
When to Choose EAA?
- When protein intake is low
- During longer workouts (90+ min)
- During weight loss with reduced calories
- For vegans who may not get all amino acids
Scientific View
Newer research shows that EAA is more effective for triggering muscle synthesis because it contains all necessary building blocks. BCAA alone cannot fully trigger muscle synthesis.
Our Recommendation
If you get enough protein (1.6+ g/kg): BCAA is sufficient for workout support.
If protein intake is low or you're vegan: Choose EAA for a more complete amino acid profile.
Best choice: Quality whey protein after workout contains both BCAA and EAA!
