Sulforaphane (SFN) is generally found in vegetables such as broccoli and cauliflower in the form of its precursor glucoraphanin (GLR).
As a precursor of sulforaphane, glucoraphanin can only be converted into sulforaphane by reacting with myrosinase in the human body to exert its efficacy.
It is an isothiocyanate. Used in health care products.
Sulforaphane is a research hotspot in the biomedical field.
