Myrosinase is an enzyme from cruciferous vegetables like broccoli and Brussels sprouts. Your body uses it to turn glucosinolates into isothiocyanates, including sulforaphane. Those compounds support cellular health pathways.
People often pair myrosinase supplements with glucoraphanin, the precursor to sulforaphane. Take it with a meal that includes glucosinolate-rich foods or as part of a broccoli sprout extract supplement. This ensures efficient conversion.
Since myrosinase does not enter your bloodstream directly, it has no known drug interactions. Large doses can cause mild stomach upset in some people. Look for products from trusted manufacturers that list enzyme activity units.
