Non-GMO 100% Vegan Dietary Supplement Brassica Oleracea Italica 10% Sulforaphane Glucosinolates 350 mg Per Capsule Guaranteed Potency Lab Verified Discussion: Broccoli is a cruciferous vegetable in the brassica family. Broccoli contains a unique class of phytochemicals known as glucosinolates, including glucoraphanin. When broccoli is consumed, chewing breaks down the glucoraphanin with the support of an enzyme called myrosinase. When glucoraphanin and myrosinase are mixed together, the compound known as sulforaphane is produced. Solaray Activated Broccoli Seed Extract supplies the myrosinase enzyme to support this process. Freeze-dried broccoli sprouts are added to this formula because they contain both glucosinolates and myrosinase enzymes.
