Hefei Fushan Yuansheng Biotechnology Co., Ltd. offers Broccoli Seed Extract 18% Glucoraphanin with high purity under the trademark EXTRABROC®, with 13 years of research and invention on Nrf2. This standardized extract delivers consistent glucoraphanin content verified by HPLC testing, ensuring reliable bioactivity for advanced formulation needs. With an ultra-stable shelf life of 2 years at room temperature and a stable annual supply capacity of 50 tons, our extract solves critical industry challenges including ingredient instability and inconsistent potency. Supported by over 30 granted patents and 10+ human clinical trials, this light yellow powder represents a scientifically validated solution for brands seeking evidence-based functional nutrition ingredients.

Product is a concentrated phytochemical substance obtained from the seeds of Brassica oleracea var. italica. Glucoraphanin acts as the stable precursor of sulforaphane, a potent activator of the Nrf2 signaling pathway.
Unlike pure sulforaphane, which degrades rapidly under heat and light, glucoraphanin maintains exceptional stability during storage and processing. That makes it a great option for firms that want predictable dosage and consistent product performance.
In the industry, 18% standardisation is a high potency standard. It allows you to achieve therapeutic doses with smaller serving sizes, reducing formulation costs while maintaining efficacy. Our extraction process is water-based, yielding a clean-label profile devoid of harmful solvent residues.
