A Rich source of Sulforaphane. Garden cress is rich in phytonutrients, also called “superfoods”, a class of compounds found in edible plants and having potent medicinal properties. Sulforaphane, which is well‐known for its capacity to neutralise reactive oxidants, is the predominant phytonutrient in garden cress. Sprouts are much richer in phytonutrients than the mature plant. That is the reason why SulforaWhite was prepared from 4 to 5 day old garden cress sprouts. In addition, SulforaWhite has a standardised sulforaphane content.
