SwansonSulforaphane from broccoli sprout extract

Sulforaphane is a plant compound that naturally occurs in cruciferous vegetables, such as broccoli, and especially in broccoli sprouts.

Broccoli sprouts are young shoots of the broccoli plant and naturally contain higher concentrations of certain plant compounds, including precursors to sulforaphane.

Sulforaphane is sourced from broccoli sprout extract, using a concentrated powder that is standardized to a fixed content.

This means that the broccoli sprout extract used contains a fixed proportion of sulforaphane, namely 0.4% of the total extract.

BroccoPhane® is a brand name for a standardized broccoli sprout extract that is used as a source of sulforaphane in supplements.

In addition to sulforaphane, broccoli sprouts also contain other plant compounds such as glucosinolates, of which sulforaphane is a derivative.
