💥 BCAA vs EAA: which one actually helps (and when)?
⏱️ ~5 min read • ✍️ Hyperforme
⚡ Quick take
- 🏋️♂️ BCAA (leucine, isoleucine, valine) → great during fasting or cutting, reduce fatigue.
- 💪 EAA → complete essential amino acids, better for muscle recovery and growth.
- 💧 Best use: EAA post-workout, BCAA intra or fasting.
🧬 Difference explained
BCAA = 3 branched-chain amino acids. EAA = all 9 essential amino acids (including BCAA) for full muscle protein synthesis.
⏱️ When to take them
- 🌅 Fasted training → BCAA protect lean mass.
- 🏃 During workout → BCAA or EAA depending on gut tolerance.
- 💥 Post-workout → EAA for full recovery.
🎯 Simple doses
- BCAA → 5–10 g before or during workout.
- EAA → 10–15 g post-workout.
💡 Hyperforme tip
Use 5 g of BCAA intra + whey isolate post for optimal recovery.
❓ FAQ
Do BCAA replace protein shakes?
No. They help recovery but don’t replace a full EAA-rich shake.
Can I take both?
You can, but it’s not necessary — EAA already contain BCAA.
