L-Theanine
L-Theanine is a naturally occurring amino acid with a global market of approximately $680 million (2024), growing steadily. It relieves anxiety, improves sleep quality, enhances cognitive ability and attention — natural, non-addictive, and widely used in functional beverages and health products.
Our L-Theanine is produced via fermentation — safer, greener, and more efficient than chemical synthesis, yielding molecular structures the human body recognizes and absorbs easily. The preferred standard for pharmaceutical-grade applications.

About Us
We are Whiteriver Bio.
Our mission is to supply pharmaceutical-grade raw ingredients that global health brands, manufacturers, and researchers can depend on — with verified purity, complete documentation, and supply timelines that never let your production down.
As global demand for nutraceuticals, functional foods, and pharmaceutical actives continues to grow, the quality and reliability of raw ingredients has never mattered more. A single compromised batch or late shipment doesn't just disrupt production — it disrupts brands, erodes trust, and costs real money.
We fulfill our mission by sourcing and supplying L-Theanine, Riboflavin (VB2), and Riboflavin Sodium Phosphate to supplement brands, contract manufacturers, pharmaceutical companies, and food producers across 40+ countries — with a COA on every batch and a quality standard that meets USP, EP, and BP compliance requirements.
Whiteriver Bio is a US-based operation built for the B2B buyer who can't afford surprises. We specialize in three pharmaceutical-grade ingredients — done exceptionally well — and we grow with the brands we supply through long-term partnerships, priority allocation, and dedicated account management.

Our Standard
Built on One Principle.
Every ingredient we supply must meet a single, non-negotiable standard: it must be exactly what it says it is, at the purity it claims, with the documentation to prove it.
Buyers who audit their suppliers know the difference between a supplier who talks about quality and one whose COAs, test methods, and batch records demonstrate it. We are the latter.
From procurement managers at contract manufacturers to R&D directors at pharmaceutical companies — our customers choose Whiteriver Bio because they cannot afford to get it wrong.
Quality Without Compromise98%+ purity is our floor, not our target. Every batch is third-party tested and ships with a complete COA — automatically, without being asked.
Reliability as a StandardSupply timelines are commitments. Pricing is transparent. Documentation is complete. Buyers who have been let down by unreliable suppliers know the difference.
Global ComplianceOur products meet USP, EP, and BP pharmacopeial standards, with cGMP-aligned processes and full batch traceability from raw material sourcing to dispatch.
Long-Term PartnershipsWe grow with the brands we supply. Priority allocation, preferred pricing, and dedicated account management for recurring supply partners.
