CONTRACT MANUFACTURING
Lief Labs
Lief Labs operates over 220,000 sq ft of manufacturing space across two FDA-registered facilities in Valencia, California. The company claims USDA Organic certification and operates an ISO/IEC 17025 accredited microbiology lab. This in-house testing capability is unusual for contract manufacturers and allows faster quality control turnaround. They produce over 5 million capsules and 1 million tablets per day. Lief Labs reports holding NSF International cGMP certification since 2010, though this could not be confirmed through NSF's public GMP directory as of March 2026. Their product line includes organic-approved tablets, a category few competitors offer. The company also provides Non-GMO Project verification assistance for brands seeking that certification. They target emerging and entrepreneurial brands with minimum orders starting at 2,500 units.
