California Manufacturing Excellence
Jarrow Formulas was founded in Los Angeles in 1977 and has manufactured its supplements domestically through sister company Jarrow Industries ever since. The manufacturing facility at 12246 Hawkins Street in Santa Fe Springs, California spans 125,000 square feet of state-of-the-art production space, housing modern equipment for encapsulation, tableting, powder filling, and liquid production.
The facility operates under Current Good Manufacturing Practices (cGMP) as required by FDA regulations for dietary supplement manufacturers, meaning the processes, equipment, documentation, and testing protocols all meet federal quality standards. Full traceability — from raw material sourcing through finished product release — is maintained for every production batch.
Probiotic Science
Jarrow Formulas is best known in the supplement market for its probiotic line, which represents decades of investment in clinical strain selection, viability technology, and formulation science. The Jarro-Dophilus line uses multiple documented probiotic strains — species and strains that have been subjects of published clinical research, not generic commodity organisms.
The Saccharomyces boulardii product represents a different category of probiotic: a yeast organism rather than a bacterium, naturally resistant to antibiotics, and specifically researched for traveler's diarrhea and gastrointestinal distress from antibiotic use. Fem-Dophilus addresses the gender-specific need for vaginal flora support through Lactobacillus strains shown in clinical studies to maintain healthy vaginal pH and microbiome balance.
Quality Commitment
The ISO certification at the Santa Fe Springs facility reflects the same quality management framework used in pharmaceutical manufacturing — a standard that most dietary supplement companies do not pursue. For consumers navigating a supplement market that contains significant product-label discrepancies and quality variation, ISO certification at the manufacturing level is meaningful evidence of consistency.
Jarrow's approach to formulation emphasizes bioavailability: using forms of nutrients that research indicates the body can absorb efficiently rather than the cheapest available form. This shows up in specific product decisions — methylated B-vitamins rather than unmethylated forms, chelated minerals rather than inorganic salts, and well-characterized probiotic strains rather than generic species.
