Beta-alanine is a non-essential amino acid that serves as a building block for carnosine, a compound stored in skeletal muscle that helps buffer acid buildup during intense physical activity. Research suggests that supplementing with beta-alanine can increase muscle carnosine concentrations over time, which may improve exercise performance during high-intensity efforts lasting one to several minutes, such as sprinting or circuit training. Studies indicate that it may also help delay the onset of neuromuscular fatigue, potentially allowing for greater training volume and supporting recovery between bouts of exercise. Some research has explored its role in body composition, though findings in that area remain more preliminary. CarnoSyn is a widely studied patented form that appears frequently in clinical trials examining these performance-related outcomes.

| Form | Dose range | Frequency | Studied for | Source |
|---|---|---|---|---|
| Capsule | 800–1,600 mg | Four times daily | Increasing muscle carnosine levels for endurance and strength | Divided dosing protocol common in trials to reduce tingling side effects |
| Powder | 2.4–3.2 g | Daily | Energy and fatigue management in older adults | Lower doses studied in elderly populations for physical function and fatigue reduction |
| Powder | 3.2–6.4 g | Daily | Exercise performance and muscle endurance | Most commonly used range in RCTs; divided into smaller doses to minimize paresthesia |
| Powder | 3.2 g | Daily | General exercise performance and fatigue reduction | Standard lower dose used in numerous clinical trials for athletic populations |
| Powder | 6.4 g | Daily | High-intensity exercise performance and muscle recovery | Higher dose studied in longer-term trials (10–12 weeks) for maximal carnosine loading |
