Lief Labs
Valencia, California
Lief Labs operates over 220,000 sq ft of manufacturing space across two FDA-registered facilities in Valencia, California. The company holds USDA Organic certification and 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 was one of the first contract manufacturers to earn NSF International cGMP certification, holding it since 2010. 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.
