The evidence, in daylight.

Sourcing standards

Every raw material is traceable to a named supplier. We audit farms and manufacturing sites in person or via video, and we require Certificates of Analysis on every incoming lot. No proprietary blends, no unnamed suppliers, no exceptions.

Testing protocols

Every finished batch is tested by Eurofins Scientific for identity, potency, heavy metals (lead, arsenic, cadmium, mercury), microbial contamination (total plate count, E. coli, Salmonella, yeast/mold), and where relevant, pesticide and glyphosate residues.

Public COAs

Every Certificate of Analysis is published at rivergrovenutrition.com/coa. Look up your batch number, printed on the bottom of every container. Nothing to hide.

Manufacturing

All Rivergrove products are made in an NSF-registered, cGMP-audited facility in Southern California. We do not white-label from generic supplement contract manufacturers.

"If a dose isn't in the clinical literature, it doesn't ship. If an ingredient isn't traceable to a named supplier, it doesn't ship. That's the standard."
