PROVEN4 NSF CERTIFIED for Sport® Performance Supplements

In the unregulated supplement industry, contamination with banned substances is a real and career-ending threat for athletes and military personnel. Studies have shown that up to 25% of supplements contain unlabeled ingredients or prohibited substances that can trigger positive drug tests,[1] jeopardizing athletic eligibility and military careers. NSF Certified for Sport® is the gold standard in third-party testing, providing independent verification that supplements are free from over 280 banned substances prohibited by major athletic organizations including the NFL, MLB, NCAA, and the World Anti-Doping Agency (WADA).[2] Every Proven4 product undergoes rigorous testing at NSF International laboratories, where each batch is screened for contaminants, verified for label accuracy, and inspected for manufacturing quality.[3] This certification is not just a label—it's a promise that what's on the bottle matches what's inside, with zero tolerance for banned substances. For military service members subject to strict Department of Defense supplement regulations[4] and athletes competing at any level, NSF Certified for Sport® supplements are the only responsible choice. When your career and reputation are on the line, trust matters. Trust Proven4.
