Verified purity. Complete documentation.

Our standard

One standard: 98% or better.

Purity is measured, not promised. Every batch is tested by HPLC before it leaves the plant.

Riboflavin and riboflavin 5′-phosphate sodium are tested to their USP monographs; a recent riboflavin batch assayed at 101.0%. L-Theanine, citicoline and citicoline sodium are tested for assay and related substances. Heavy metals are measured on every batch, and microbial limits wherever the specification calls for them.

    Fermentation

    Controlled, monitored fermentation with in-process checks at each critical step.

  3. 03

    Purification

    Decolorization, concentration and drying bring each product to specification.
