Beta-Alanine: The Tingly Pre-Workout Supplement

That harmless skin-tingling from your pre-workout? That’s usually beta-alanine — one of the more evidence-backed supplements for pushing out extra reps.

What it does

Beta-alanine raises muscle carnosine, which buffers the acid that builds up during hard effort. The result: modestly better muscular endurance in the ~1–4 minute effort range — think higher-rep sets, intervals and short conditioning. It won’t boost one-rep max strength.

Dosing and the tingles

• Dose: ~3–6 g/day, taken consistently — it works by building up over weeks, not from a single dose. Timing doesn’t matter.
• The tingles (paraesthesia) are harmless; split the dose or use sustained-release if they bother you.
• Worth it? A minor but real helper for endurance-style training — well behind creatine in priority. Nail training, protein and sleep first.

Quick answers

What does beta-alanine do?

It buffers muscle acid, modestly improving muscular endurance in efforts lasting roughly 1–4 minutes. It doesn’t raise max strength.

Why does beta-alanine make me tingle?

The harmless tingling (paraesthesia) is a normal effect. Split the dose or use a sustained-release form if it bothers you.
