Formed when cruciferous vegetables are chopped or chewed, sulforaphane is one of the most intensively studied plant compounds in prevention research. Values are given as its glucoraphanin precursor.

What is Sulforaphane?

Sulforaphane is a dietary isothiocyanate that plays a critical role in activating the body’s own antioxidant defences. While many general diets overlook it, maintaining optimal levels of Sulforaphane is frequently tracked by people working to optimize their hs-CRP (inflammation).

How Sulforaphane Impacts hs-CRP (inflammation)

Research links diets rich in Sulforaphane to changes in hs-CRP (inflammation). Diets naturally abundant in this compound often support lower hs-CRP (inflammation) markers by switching on the Nrf2 detoxification pathway.

Encyclopedia Insight: For maximum absorption, pair Sulforaphane-rich foods with raw or lightly steamed cruciferous vegetables plus a pinch of mustard seed to optimize bioavailability.
