PRODUCT COMPARISON
INDEPENDENT LAB TEST RESULTS
A third-party independent laboratory tested the top 30 sulforaphane supplements available in the US.
Everything on this page is based on those results.
Links to the certified test results are below.
26mg sulforaphane per serving
Why does BROQ contain 30% more sulforaphane than shown on the label?Click on product image to view certified lab results.
On our label, we promise to deliver 20mg of sulforaphane per serving.
We produce BROQ with 20-30% more than that amount.
This is to allow for possible effects of exposing product to heat.
To maintain full potency, keep refrigerated after opening.
See how the values in the above chart were calculated based on the independent lab results here.
70% BIOAVAILABLE
The independent lab results show that only these two supplements contain sulforaphane:
One serving of BROQ™ contains 26mg of sulforaphane.
At 70% bioavailability, the expected amount that will enter circulation in your body is 18mg.
One serving of BrocElite Plus™ contains 11mg of sulforaphane.
At 70% bioavailability, the expected amount that will enter circulation in your body is 8mg.
30% BIOAVAILABLE
The independent lab results show that these supplements contain glucoraphanin and myrosinase (without any sulforaphane):
The bioavailable sulforaphane per serving of these 11 products ranges from 0mg to 3.3mg.

IN THE TABLE BELOW...
Column 1 ("Product") is the name of the product.
Column 2 ("S?") indicates whether or not the product contains sulforaphane.
Column 3 ("G?") indicates whether or not the product contains glucoraphanin (AKA sulforaphane glucosinolate).
Column 4 ("M?") indicates whether or not the product contains myrosinase.
Column 5 ("S in product") indicates the amount (in mg) of sulforaphane contained in one serving of the product.
Column 6 ("Potential S") indicates the potential sulforaphane (in mg) that could be produced from one serving of the product. (See how this was tested, below.)
Column 7 ("%") indicates the mean bioavailability of the sulforaphane shown in column 6. For products containing sulforaphane, mean bioavailability is 70%. For products containing glucoraphanin and myrosinase, mean bioavailability is 30%. For products containing only glucoraphanin, mean bioavailability is 10%. (Source)
Column 8 ("Bioavail S") is the expected sulforaphane (in mg) that will enter circulation after consuming one serving of the product. It is calculated by multiplying the previous two columns ('Potential S' x '%').
'Potential S' — The potential sulforaphane that could be produced from one serving of product
One serving of product was hydrolyzed, by adding water, for 2 hours, and sulforaphane was measured via HPLC.
'S in Product' — Sulforaphane contained in one serving of product
One serving of product was tested via HPLC for sulforaphane quantity. No hydrolysis was performed.
'G in product' — Glucoraphanin (sulforaphane glucosinolate) contained in one serving of product
One serving of product was tested via HPLC for glucoraphanin quantity.
NOTE—FOR ALL PRODUCTS IN THE '10% BIOAVAILABILITY' CATEGORY:
For these products (i.e. ones containing no sulforaphane or myrosinase), we compared 'Potential S' to 'G in Product'. We chose the larger value of the two and multiplied by 10% to calculate the amount of bioavailable sulforaphane in one serving ('Bioavail S').
