Description

Each dose contains 100% pure Beta Alanine, a naturally occurring beta amino acid that combines with L-histidine in the body to form carnosine. Carnosine helps buffer acid build-up in your muscles during hard efforts, keeping pH levels stable and delaying the fatigue that typically limits performance. With zero calories and a clean, simple ingredient list, it’s a focused solution for athletes who want to train harder and recover stronger.

Beta Alanine works by building up in your system over time, so consistent use is key. As your muscle carnosine levels increase, you’ll begin to notice improvements in how long you can sustain high-effort bursts, how sharp you feel during repeat sessions, and how quickly you can bounce back.

Whether you're training for CrossFit, track sprints, or cycling time trials, Beta Alanine can give you the edge by enhancing your capacity to perform and resist fatigue in those crucial moments when it counts most.

How does it work

Beta Alanine increases the amount of carnosine stored in your muscles. Carnosine acts as a buffer, reducing the acidity that builds up during intense activity. When you work out hard, your muscles produce hydrogen ions that make them more acidic. This is what contributes to that burning sensation and eventual fatigue. More carnosine means better pH control, which allows your muscles to keep working effectively for longer.

Since Beta Alanine builds up over time, its benefits aren't instant, but after several weeks of consistent use, most athletes see significant improvements in performance during short bursts of maximal effort. Regular dosing is essential to get the full effect.
