Beta-Alanine
B-Alanine
Beta-Alanine is a non-proteinogenic amino acid (β-alanine vs the standard α-alanine in proteins) that combines with histidine to form carnosine in muscle tissue. Carnosine is a major intramuscular pH buffer that delays muscle fatigue during high-intensity exercise (60-240 second efforts where lactic acid accumulation is rate-limiting).
Split into 800mg-1.6g doses to avoid paresthesia.
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
How it works
Beta-Alanine works through chronic muscle carnosine elevation:
Carnosine Synthesis
β-Alanine combines with histidine via carnosine synthase to form carnosine. β-Alanine is rate-limiting; histidine is abundant.
pH Buffering
Carnosine is the major intramuscular pH buffer at physiological pH. During high-intensity exercise, lactic acid accumulation lowers muscle pH; carnosine buffers H+ ions.
Time-To-Fatigue
Higher muscle carnosine delays the pH drop that drives fatigue, extending time-to-failure in 60-240 second efforts (most weight room sets, sprint intervals, CrossFit WODs).
Loading Required
A single dose has minimal acute effect. 4-8 weeks of daily 4-6g loading raises muscle carnosine 50-80%; effect persists weeks after discontinuation.
Maintenance Dose
1-2g daily can maintain elevated carnosine after loading phase.
Paresthesia
Bolus β-Alanine causes histamine release producing tingling/itching sensation lasting 30-60 minutes. Harmless but uncomfortable. Split-dosing (800mg-1.6g per dose, multiple times daily) avoids this. Sustained-release formulations also reduce paresthesia.
What to expect
Days 1-7: paresthesia common; performance unchanged.
Weeks 2-4: muscle carnosine rising; subtle performance improvements.
Weeks 4-8: peak benefit. Maintenance phase begins.

Side effects & safety
Commonly reported
- Paresthesia (tingling, itching) - HARMLESS but uncomfortable
- Mild flushing
Less common & notes
- Allergic reactions rare.
- Long-term safety good.
- Chronic high-dose use very rarely associated with taurine depletion (β-Alanine and taurine share transporters) - typically clinically minor.
Pharmacokinetics
Storage. Powder/capsule. Cool dry location.
Regulatory status
Dietary supplement (US, DSHEA).
