DOES IT WORK?
Results vary. Broccoli flower powder is essentially the same as broccoli powder (the floret IS the flower). Contains glucoraphanin that converts to sulforaphane. Same story as broccoli: the compound is great, but supplement blend doses are typically too small. This is often just broccoli listed differently on a label.
