What is Sulforaphane?

Sulforaphane is a compound formed when you chew broccoli sprouts, where the precursor glucoraphanin meets the enzyme myrosinase. It is the most potent natural activator of Nrf2, the master switch that turns on hundreds of the body's own antioxidant and detoxification genes. Human trials link sulforaphane to improved clearance of airborne pollutants, better cardiometabolic and inflammatory markers, and promising cognitive effects. Because the enzyme is heat-sensitive, supplements work best when they pair stabilized glucoraphanin with active myrosinase. Three-day-old broccoli sprouts are by far the richest food source.
