Calculate beta-alanine dose. Beta-alanine + histidine → muscle carnosine → intramuscular pH buffer. Best evidence for 1-4 minute high-intensity exercise (CrossFit-WOD, rowing, mid-distance cycling/running, MMA rounds). Loading + paresthesia management critical. Math, not medical advice.

Why split dosing matters
- Paresthesia threshold: single doses ~800-1000 mg trigger tingling for most people. Higher = more intense tingling.
- Carnosine loading is the rate-limiter, not single-dose magnitude: total daily dose matters; you can’t speed loading with bigger single doses.
- Standard protocol: 4 × 1.2g spaced throughout day (with meals). Maintains plasma availability for carnosine synthesis without paresthesia.
- Sustained-release (CarnoSyn SR, Versa-Lab): single 1.6g dose without strong tingling. Premium price. Useful if you can’t split doses.
- Loading takes 2-4 weeks: carnosine accumulates slowly. Don’t judge effects in first 7 days.
What beta-alanine does NOT help
- Single-rep max strength (CNS / neural; not pH-limited).
- Sprints under 30 seconds (creatine phosphate dominates, not pH).
- Long endurance over 10 minutes (oxidative; lactate steady-state).
- “Pump” — that’s a citrulline/NO effect, not carnosine.
- The sweet spot is 60s-240s sustained high-intensity — where intramuscular pH drops are performance-limiting.
Stacking
- Beta-alanine + creatine: classic combo (different mechanisms). Standard in most pre-workouts.
- Beta-alanine + sodium bicarbonate: additive buffer effects (intramuscular + extracellular). Bicarb causes GI issues — careful dosing.
- Beta-alanine + citrulline: common pre-workout combo (NO + buffering).
- Beta-alanine in pre-workout drink: if loading, the drink alone won’t deliver enough — supplement separately throughout the day.
Safety
- Paresthesia: harmless, lasts 30-90 min, manageable by dose splitting.
- Theoretical concern: long-term high-dose may deplete taurine (shared transporter) — clinically not observed at typical doses.
- Pregnancy/lactation: safety not established; avoid.
- Long-term safety up to 12 months established; longer-term data limited but no signals.
