A Celebration of Quality and Teamwork

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.

Understanding the NSF/ANSI 455‑2 Standard

The NSF/ANSI 455‑2 GMP standard strengthens traditional GMP requirements by emphasizing:

• Robust quality management systems
• Thorough documentation and traceability
• Strong supplier qualification practices
• Consistent audit expectations
• Comprehensive facility and equipment controls

These elements help ensure that dietary supplement manufacturing is safe, controlled, and reliable.

What a “Grade A” Rating Represents

A Grade A rating indicates strong performance across all audited areas, including:

• Quality control
• Manufacturing operations
• Sanitation and facility management
• Employee training
• Material handling and traceability

It reflects the daily work of our team — the people who maintain our processes, uphold our standards, and continuously look for ways to improve.

A Culture of Quality

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’re proud of this accomplishment and even more proud of the team behind it.

We will continue investing in training, technology, and process improvements to ensure we remain a reliable and responsible manufacturing partner.
