Ingredient and preparation

Sulforaphane products may use broccoli sprout preparations, glucoraphanin, myrosinase or combinations. These are not interchangeable labels.

Sources: National Library of Medicine, PubMed

Evidence and limits

The cited cancer RCT review found eight studies with variable regimens and substantial clinical and methodological heterogeneity. It reported inconsistent PSA findings and no pooled analysis, so it cannot establish cancer treatment or prevention for a broccoli-extract product.

Sources: National Library of Medicine, PubMed

Safety and a useful record

Preparation and precursor conversion can vary between products. Review product identity and health context instead of treating a pathway claim as a treatment claim.

Sources: National Library of Medicine, PubMed, National Center for Complementary and Integrative Health

Record whether the label names sulforaphane itself, glucoraphanin or myrosinase, plus the outcome being followed.
