Beta-Alanine
Beta-alanine raises muscle carnosine, which buffers the acidity that builds during hard, sustained efforts. It reliably adds a rep or two in the one-to-four-minute range.
Effective dose
3.2–6.4 g per day for at least four weeks. Split into doses of 1.6 g to reduce tingling.
Timing
Daily, any time. It does not work acutely, so pre-workout-only dosing is pointless.
What it is
A non-essential amino acid that combines with histidine to form carnosine inside muscle tissue.
How it works
Carnosine soaks up hydrogen ions produced during glycolysis, delaying the pH drop that forces you to stop. Saturation takes weeks of daily dosing.
What the research shows
- Meta-analyses show small but consistent improvements in exercise lasting roughly 60 seconds to four minutes.
- Benefits are negligible for single maximal lifts or long steady endurance work.
Best for
Forms to look for
- Plain powder
- Sustained-release capsules
- Standard inclusion in pre-workouts
What to watch out for
Paraesthesia — the skin tingle — is harmless and dose-dependent. Split doses if it bothers you.
Sourcing partners
Coming soonWe are onboarding a short list of vetted suppliers for beta-alanine, each with published certificates of analysis and third-party identity testing. Direct purchasing will open here once those partners are live.
FAQs
Why does beta-alanine make me tingle?
It briefly activates sensory nerve receptors in the skin. It is harmless and fades within an hour.
