How It Works
Beta-alanine + histidine → carnosine (via carnosine synthase). Carnosine buffers H+ ions produced during glycolysis. Also acts as antioxidant and anti-glycation agent. Increases muscle carnosine by 40-80% over 4-10 weeks.
Dosage & Timing
Dosage Guide
Daily Dose2-5 g
TimingDaily (split into 0.8-1.6g doses to avoid paresthesia). Timing irrelevant — saturation effect.
BioavailabilityAbsorption: near 100%. Competition with taurine for transporter — take separately if supplementing both.
Optimal Timing
Take with food. Consistency matters more than timing for most supplements.
Best Forms (Ranked)
Beta-Alanine (standard) — ★★★★☆
Effective but causes paresthesia in single large doses.
Sustained-Release Beta-Alanine — ★★★★★
Reduced paresthesia. Better compliance. Slightly more expensive.
Benefits
- 10-15% improvement in 1-4 min high-intensity performance
- Reduced neuromuscular fatigue
- Improved training volume
- Synergistic with creatine
Side Effects
- Paresthesia (tingling/flushing) — harmless, dose-dependent, mitigated by split dosing or sustained-release
✅ Good For
- Sprint/power athletes
- Combat sports
- Rowing/swimming (1-4 min events)
- HIIT/CrossFit
⚠️ Skip If
- Endurance-only athletes (>10 min events — less benefit)
- Those who cannot tolerate paresthesia
