Broccoli sprout extract (BroccoMax / Avmacol)

Tier 3 — weak evidence · Sulforaphane source · Detox · Liver

Concentrated young-broccoli-sprout powder formulated to deliver glucoraphanin together with active myrosinase enzyme, so sulforaphane is generated on ingestion. Trial-validated branded forms (Avmacol, BroccoMax) have RCT data for air-pollution detox biomarkers, mild liver enzyme improvement, and bladder cancer-related endpoints. Dose for dose, branded enzyme-active forms outperform generic glucoraphanin-only powders.

Dose: 1–2 capsules of standardised enzyme-active product daily, supplying ~30 mg glucoraphanin
