Our AHCC® is sourced directly from Amino Up Co., Ltd. in Sapporo, Japan — the original developer and exclusive manufacturer of authentic AHCC®. AHCC® (Active Hexose Correlated Compound) is a proprietary extract produced through a patented fermentation process, and all clinically studied AHCC® worldwide originates from this single facility.
Because AHCC® is not a generic mushroom powder or standard shiitake extract, sourcing matters. Only material manufactured by Amino Up is considered authentic AHCC® and is the ingredient used in published clinical research. Products not derived from this source are not the same compound studied in the literature.
We use genuine AHCC® and label it transparently, without diluting it in unclear proprietary blends. For additional information about manufacturing and quality control standards, you can visit Amino Up directly at: https://aminoup.info/en/ahcc
