Glucoraphanin is a compound found in broccoli and other cruciferous vegetables, particularly concentrated in broccoli sprouts. In the body or during food processing, an enzyme (myrosinase) converts it into sulforaphane, the compound most associated with broccoli's studied effects.
Why it’s used
Taken to support antioxidant and detoxification pathways, largely through its conversion to sulforaphane.
What the evidence says
There is no NIH ODS fact sheet for glucoraphanin specifically. Human research more often studies sulforaphane or broccoli sprout extracts than glucoraphanin itself, and conversion efficiency varies by product and by the individual's gut bacteria, which complicates drawing firm conclusions about glucoraphanin as a standalone ingredient.
Context
Studies of broccoli sprout extracts have used various glucoraphanin-to-sulforaphane ratios and doses, and myrosinase activity in a given product significantly affects how much sulforaphane is actually produced and absorbed.
