About Broccoli Seed/Sprout Extract
Glucoraphanin-standardized broccoli seed/sprout extract, the precursor to sulforaphane (an Nrf2 antioxidant-pathway activator). Distinct from the pure `sulforaphane` entry: this scores the labeled extract mass. Small RCTs show changes in SURROGATE markers only (liver ALT, urinary detox conjugates); a 2025 glucose RCT (n=74) missed its primary fasting-glucose endpoint. Aliases scoped to seed/sprout/branded forms so whole-head/floret/greens 'broccoli' still reads as whole food.
What Broccoli Seed/Sprout Extract supports
- Glucoraphanin extract; surrogate-marker evidence only
How much Broccoli Seed/Sprout Extract to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
200–600
mg
EXTRACT-mass range (products label extract weight). Trials dose the active (glucoraphanin ~60mg / sulforaphane), NOT extract mass, so mass is a rough proxy — same activity-vs-mass caveat as white_kidney_bean. Raw un-activated extract yields little sulforaphane without myrosinase.
Clinical evidence
Limited clinical evidence. Surrogate endpoints only; glucose RCT missed primary; extract mass ≠ active dose
