Beta-Alanine

Beta-Alanine is a non-essential amino acid that serves as a precursor to intramuscular carnosine. Carnosine is a dipeptide that acts as a pH buffer within the muscle fiber — it neutralizes H⁺ ions produced during high-intensity exercise, delaying muscular acidosis and consequently fatigue. Beta-Alanine is the limiting factor in carnosine synthesis, meaning the more Beta-Alanine available, the more carnosine the muscle can produce and store.

• Increased intramuscular carnosine stores
• Delayed muscular acidosis during intense efforts
• Greater fatigue tolerance in long sets (8–15 reps)
• Performance improvement in efforts lasting 1 to 4 minutes
• Cumulative benefit — effect increases with continuous use
• Useful in high-intensity intermittent sports

• •Resistance training practitioners with high-volume workouts
• •High-intensity sport athletes (MMA, swimming, cycling, rowing)
• •Those doing long sets with many repetitions
• •CrossFit and HIIT athletes
• •People seeking to delay fatigue in intense training

3.2g to 6.4g per day. To minimize paresthesia (tingling), split into 1.6g doses throughout the day. Effects appear after 4 to 6 weeks of continuous use — regular use is necessary to accumulate muscle carnosine.

Beta-Alanine is most indicated for those doing high-volume training with long sets or practicing high-intensity sports lasting 1 to 4 minutes. For pure strength training with short sets (1–5 reps), the benefit is smaller — carnosine is not the limiting factor in these efforts. The tingling (paresthesia) is harmless and can be minimized by splitting the daily dose into smaller portions. The effect is cumulative — using it only on training days is not enough. Use continuously for at least 4 weeks to feel the real benefit.

Beta-Alanine is one of the supplements with the strongest scientific evidence for performance. Meta-analyses confirm that supplementation increases muscle carnosine stores by 40–80% after 4–10 weeks, with performance improvement in high-intensity exercises lasting 1 to 4 minutes. The effect is smaller in very short (<60 seconds) and very long (>10 minutes) efforts. Paresthesia (tingling) is a well-documented and harmless side effect, caused by activation of cutaneous receptors — it does not indicate toxicity.

Paresthesia (skin tingling) — the most common and harmless side effect. Occurs mainly on the face, neck and hands. Can be minimized by splitting the dose into 1.6g portions. Sustained-release versions significantly reduce this effect.
