Beta Alanine-SR: A Sustained-Release Formula for Muscle Endurance
Thorne’s Beta Alanine-SR provides a pure, sustained-release form of the amino acid beta-alanine, featuring the clinically-studied SR CarnoSyn®. This advanced supplement is designed for athletes and active individuals who want to enhance muscular endurance, reduce fatigue, and optimize their training capacity. Beta-alanine works by supporting the body’s natural production of carnosine, a key buffer against muscle acidity. The sustained-release format ensures a steady supply to the muscles while minimizing the tingling sensation often associated with standard beta-alanine.*
How It Works: Buffering Lactic Acid for Longer Performance
This formula works by providing the direct building block for carnosine, which is a primary line of defense against muscle fatigue.
Increasing Carnosine Levels
During high-intensity exercise, your muscles produce lactic acid, which leads to a drop in pH and the familiar “burning” sensation that causes fatigue. Beta-alanine is the key precursor to carnosine, a dipeptide that is highly concentrated in muscle tissue. Carnosine acts as a powerful intracellular buffer, soaking up the excess acid. Therefore, it helps to maintain a normal muscle pH during intense exertion.*
The Sustained-Release Advantage
The patented SR CarnoSyn® in this formula is delivered in a sustained-release format. This allows the beta-alanine to be absorbed more gradually, which helps to prevent the harmless but often uncomfortable skin-tingling sensation (paresthesia) that can occur with immediate-release versions. This steady delivery also supports consistent carnosine levels in the muscles, leading to improved endurance, increased work capacity, and better overall athletic performance.*
