Beta-Alanine
Increases muscle carnosine to buffer acid during high-intensity exercise, extending endurance for 1-4 minute efforts.
Beta-alanine is a non-essential amino acid that increases muscle carnosine levels. Carnosine acts as a buffer against the acid buildup during intense exercise, delaying fatigue. It's most effective for activities lasting 1-4 minutes where lactic acid buildup limits performance.
Rate-limiting precursor for muscle carnosine
Carnosine buffers hydrogen ions during exercise
Extends time to exhaustion at high intensities

3.2-6.4g daily
Take with food
| Form | Type |
|---|---|
| 💊CarnoSyn® sustained-release tablets | Recommended |
| 🧪Regular powder | Alternative |
| 💊Pre-workout blends (check dose) | Alternative |
CarnoSyn is the patented, most-studied form. Sustained-release reduces tingling. Many pre-workouts underdose beta-alanine.
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: Split doses (0.8-1.6g, 2-4x/day) to minimize tingling. Total daily dose matters, not timing relative to workout. Effects build up over 2-4 weeks.
More time before fatigue in 1-4 minute efforts
Ability to push harder before hitting failure
Harmless skin tingling, especially at higher doses
Limited data; not recommended during pregnancy
Not banned; legal ergogenic aid; used by Olympic athletes
May compete for uptake; separate timing if taking both
Tip: Split into smaller doses; use sustained-release form
Tip: Reduce single dose size

“Creatine supplementation demonstrated ergogenic benefits for competitive swimmers, although the evidence supporting the use of this supplement is still limited.”
Ashtary-Larky D et al. • Nutrients (2025)
“Conclusions: The combination of creatine and β-alanine supplementation may be effective for enhancing high-intensity exercise performance but has no greater effect on maximal strength, body composition, or measures of aerobic capacity compared to creatine or β-alanine alone.”
