What is Broccoli Seed Extract Powder?
Broccoli Seed Extract Powder is derived from high-quality broccoli seeds (Brassica oleracea var. italica), known for its naturally high content of glucoraphanin-the precursor to sulforaphane, a well-researched bioactive compound.
Through advanced extraction and processing technology, we provide both glucoraphanin-standardized extract and sulforaphane-active products, suitable for nutraceutical, functional food, and pharmaceutical applications.
