Lief Labs is pleased to announce that we have completed the NSF Audit for NSF/ANSI 455-2 Good Manufacturing Practices (GMP) for Dietary Supplements, earning a Grade A rating.
This achievement is not about setting ourselves apart. It's about honoring the responsibility we carry as a contract manufacturer. Our partners trust us with their brands, and consumers trust those brands with their health. Meeting the NSF/ANSI 455-2 standard is one way we demonstrate that we take that responsibility seriously.
"Receiving an 'A' grade on our recent annual NSF audit reflects the consistent focus, accountability, and operational excellence demonstrated across all departments in support of our compliance and quality objectives."
- Celeste Arriage, Director Product Development and Compliance
The NSF/ANSI 455-2 GMP standard strengthens traditional GMP requirements by emphasizing:
These elements help ensure that dietary supplement manufacturing is safe, controlled, and reliable.
A Grade A rating indicates strong performance across all audited areas, including:
It reflects the daily work of our team - the people who maintain our processes, uphold our standards, and continuously look for ways to improve.
At Lief Labs, quality isn't a differentiator - it's a core value. This certification is a moment to recognize the systems we've built, the people who uphold them, and the trust our partners place in us.
We will continue investing in training, technology, and process improvements to ensure we remain a reliable and responsible manufacturing partner.
