Twin Arbor Labs

Twin Arbor Labs is an ISO 17025 accredited analytical and microbiological testing laboratory. It works with supplement brands, cosmetic makers, and food and beverage companies, running third-party tests on raw ingredients and finished products. Common work includes heavy metals, potency, identity, adulterant screening, fatty acid profiling, and food safety testing, including kombucha, juice, and hop smoke taint.

The lab is family-operated and independent, so it reports results without ties to a client's supply chain. Clients typically request a quote through the website, and the lab offers delivery. It is located on Empresa Drive in San Luis Obispo on California's Central Coast.
