Broccoli sprout extract

View my plan →

The short answer

A precursor-delivery product whose active sulforaphane yield varies widely.

Evidence and scope: Emerging evidence
This status does not grade the ingredient for every goal, outcome, or person.
Important limitation: Early human findings are hypothesis-generating; efficacy, long-term safety, and optimal dose remain uncertain.
Before deciding: Key concern: Same cautions as sulforaphane; raw-sprout contamination matters in pregnancy or immunocompromise.

01 / PRACTICAL GUIDE

Dose, absorption, and combinations

These are indication-specific reference or studied ranges—not a personalized prescription. Start with the objective, then check the form, label, medicines, and health conditions.

Reference range by objective

Meeting usual needsUse a product reporting sulforaphane yield, not only glucoraphanin milligrams

Reference or studied range—not a personalized prescription. The product label or a clinician may specify a different dose.

Dose source ↗

More is not automatically better. A clinician or product label may specify a different amount.

Absorption / solubilityFormulation-dependent

Not usefully classified as a fat- or water-soluble vitamin; absorption depends on the salt, extract, delivery system, and meal.

How it is commonly taken

Take as studied; myrosinase content is decisive.

Do not combine casually

Same cautions as sulforaphane; raw-sprout contamination matters in pregnancy or immunocompromise.

What the research says

We keep supportive, mixed, negative, safety, and contextual findings together. The headline never replaces the underlying papers.

Broccoli sprout beverage and airborne-pollutant excretion

Excretion biomarkers rose for benzene by 61% and acrolein by 23%, but not crotonaldehyde. This demonstrates short-term pharmacodynamic activity in a high-exposure setting, not reduced cancer, lung disease, cardiovascular events, or mortality.

Published: 2014Duration: 12 weeksn=291 participants

Study design and methods

Design: Randomized controlled clinical trial
Population: 291 adults in a rural Chinese region with substantial airborne-pollutant exposure
Intervention: Broccoli sprout beverage providing 600 μmol glucoraphanin and 40 μmol sulforaphane daily versus placebo
Outcome: Urinary excretion biomarkers for benzene, acrolein, and crotonaldehyde
