“Dietary supplements containing sulforaphane's precursor molecules, glucoraphanin and myrosinase, are widely available to consumers. Myrosinase is an enzyme, however, and may not be shelf-stable without refrigeration, compromising its ability to hydrolyze glucoraphanin to sulforaphane.”

“The end product of the reaction is an isothiocyanate compound that activates cytoprotective mechanisms in humans in a hormetic-type response. The seeds of cruciferous vegetables are particularly good sources of isothiocyanates, but care must be taken to preserve the myrosinase, which is heat sensitive.”

“When cruciferous plants are crushed or damaged by insect attack or human consumption, the myrosinases hydrolyze the glucosinolates to yield a variety of degradation products, including isothiocyanate compounds.”

“The enzyme is heat-sensitive and rapidly denatures during normal cooking processes. Adding ground mustard seed (which is rich in myrosinase) to cooked vegetables provides a culinary workaround to myrosinase losses incurred during cooking.”

“Investigators estimated that the global-cognition difference corresponded to about two years of age-related change. Dr. Patrick then turns to sulforaphane, which is formed when myrosinase converts glucoraphanin from cruciferous vegetables.”

“A short study also found changes in selected immune-cell phenotypes and metabolism, extending research into how mitochondrial support may influence cellular function. Sulforaphane is produced from glucoraphanin through the action of myrosinase and activates NRF2-regulated cytoprotective pathways.”

“Broccoli sprouts, lightly cooked broccoli, and myrosinase-rich mustard-seed powder are practical ways to support sulforaphane formation, while supplement composition and conversion can vary.”

“Choosing a supplement that contains both glucoraphanin (the precursor to sulforaphane), as well as myrosinase (the enzyme that converts glucoraphanin to sulforaphane), is crucial to ensuring optimal sulforaphane delivery.”

“Glucoraphanin can be converted to sulforaphane by the enzyme myrosinase, making enzyme activity an important feature of a formulation. Small human experiments found greater sulforaphane bioavailability from preparations with active plant myrosinase than from glucoraphanin alone.”

“Cooking temperatures inactivate myrosinase, effectively preventing isothiocyanate conversion and allowing unhydrolyzed glucosinolates to pass into the gut. In humans, myrosinase-producing gut bacteria can convert these glucosinolates to their cognate isothiocyanates.”
