Sulforaphane

Sulforaphane

Sulforaphane is an isothiocyanate from cruciferous vegetables, formed when glucoraphanin is hydrolyzed by myrosinase. It is used to induce Nrf2-related detox enzymes. It is not the same class as carotenoids such as lycopene.

01

Why supplement?

✓

Isothiocyanate induction of Nrf2

Sulforaphane activates Nrf2 and upregulates phase II enzymes such as quinone reductase and GST. The setting is cellular detox and oxidative-stress adaptation, not vitamin A replacement. Fresh broccoli needs chewing to release the enzyme; supplements often use seed extract or stabilized sulforaphane. Bloating is a common tolerance issue and can be shifted to after meals.

✓

Not anthocyanins or lutein

Anthocyanins are petal and fruit-skin pigments; lutein is a macular carotenoid. Sulforaphane has no conjugated chain of a colored antioxidant. Recognize isothiocyanate milligrams or seed-extract labeling. The path also differs from curcumin polyphenols. Buy by sulforaphane or glucoraphanin plus active-enzyme notes.
