You take your pre-workout, and a few minutes later your face, neck, and hands start to tingle — a light prickle, almost an itch. First time it happens, it can be unsettling. Most people Google it mid-warmup.

Here's the short version: it's harmless, it's expected, and it's the sign that one of the most well-researched performance ingredients is in your system. It's called paresthesia, and it comes from beta-alanine.

What's Actually Happening

The tingle is harmless

Paresthesia is a temporary nerve sensation — beta-alanine briefly activates receptors just under the skin. It peaks around 10-20 minutes in and fades on its own. No harm, no lasting effect. It's a quirk of the ingredient, not a warning sign.

What it actually does

Beta-alanine raises muscle carnosine — a buffer against the acid build-up that burns and slows you down in hard sets. More carnosine means you fight off fatigue longer. The benefit you feel isn't the tingle; it's the extra reps before the burn shuts you down.

Where it helps most

The research is strongest for high-intensity efforts lasting roughly 1-4 minutes — think long sets, metcons, sprint intervals, and the back half of a hard workout. Exactly the moments where most people fade.

The Dose Is The Whole Story

Here's the catch: beta-alanine only works at a real dose. The research clusters around a clinically meaningful daily amount — and plenty of pre-workouts sprinkle in a fraction of that, just enough to make you tingle so it feels like it's working. The tingle is easy to fake. The benefit isn't.

Where Ignite Fits

Ignite uses 1.5g of CarnoSyn beta-alanine — the patented, research-grade form — and it's printed right on the label, not buried in a proprietary blend. When you feel the tingle from Ignite, it's not a marketing trick. It's a meaningful dose of an ingredient that earns its place, doing exactly what the studies say it does.
