NASC members are responsible suppliers of animal health and nutritional supplements who are committed to quality, vigilance, and continuous improvement. Companies must qualify to become NASC members and must sign our Member Accountability Guidelines agreeing to comply with NASC requirements.
The companies listed below with the green Audited Member designation next to their names are member companies that have earned permission to display the NASC Quality Seal on their products. They accomplish this by passing a comprehensive third-party audit every two years and maintaining ongoing compliance with rigorous NASC quality standards.
