The Active Ingredient Is: Beta-Alanine (CarnoSyn)

Beta-Alanine is a non-essential amino acid that boosts muscle carnosine levels to support performance during intense workouts, and this version is CarnoSyn beta-alanine, a widely used, scientifically studied option for athletic support.

This ingredient is supplied in a clean, supplementary form designed to boost buffering capacity and is commonly used to support sustained power output during tough efforts.

What Does Beta-Alanine Do?

Beta-Alanine helps with buffering acid buildup in muscles and helps delay fatigue during repeated high-intensity exercise, supporting daily training performance.

Studies show beta-alanine can raise muscle carnosine levels and is linked with extended endurance in high-intensity efforts, aligning with EFSA-consistent interpretations of muscle function and energy production.
