Sigma-tau HealthScience USA

Sigma-tau HealthScience USA, now operating as part of Alfasigma USA, is a specialized healthcare company focused on metabolic health and science-based nutritional supplements. The company is a pioneer in carnitine research, developing products that address metabolic deficiencies and support reproductive health, most notably through the Proxeed brand. Their portfolio includes medical foods and dietary supplements designed for gastrointestinal health, including the probiotic VSL#3. Following the 2015 merger between Sigma-tau and Alfa Wassermann, the company integrated its operations to leverage a broader range of therapeutic solutions in the prescription and over-the-counter markets. Sigma-tau HealthScience maintains a strong emphasis on clinical validation for its nutraceutical products, distinguishing itself from standard supplement manufacturers. The organization continues to serve patients and healthcare providers in the United States from its headquarters in Louisiana.
