BROQ is a natural supplement that delivers a powerful compound called sulforaphane, which has many benefits for your health, body and brain.

BROQ delivers more than double the amount of bioactive sulforaphane per serving of any other product you can buy. (See how it compares.)

BROQ is one of only two supplements in existence that contain sulforaphane. (Other supplements contain substances that your body can convert into sulforaphane.)

BROQ is the brand name in North America for the French product Prostaphane®, which has been tested extensively in clinical trials.

Sulforaphane is the compound in broccoli and other cruciferous vegetables that is responsible for their many health benefits.

There's been an explosion of research about sulforaphane in the past ten years.

It rhymes with "rock"!

The short answer is: yes, but not nearly the level of sulforaphane that's in BROQ.

You'd have to eat approximately three pounds of raw broccoli a day to get the equivalent of one daily serving of BROQ. (Cooking greatly reduces the amount of sulforaphane.)

And, even then, you won't know how much you're getting, as there's a lot of variability due to freshness and growing conditions.

If you're prepared to do the work, yes, you can get as much sulforaphane as in a daily serving of BROQ.

But you'd need to grow and eat about this muchrawbroccoli sprouts each day:

Thank you for asking!

Yes, we do!! 😀

Here it is:


Probably not. And, if you do, it will be a gradual, slow change.
This is true of any supplement or vitamin that affects your overall health.

Any change that takes place happens too gradually to be noticed.

You might want to ask your doctor whether there are any tests that could be performed before you start taking BROQ—and then again, say, six months after taking it daily. (Give them a link to our site!)

If you do that, we'd love to hear what you find!!

As the most potent source of natural sulforaphane that you can get, BROQ supports your health and wellbeing in the following ways (click number for links to studies):

Sulforaphane is the most potent naturally occurring molecule that activates the NRF2 genetic pathway, which regulates over 200 genes.​

Many of these genes are associated with keeping us healthy—by fighting oxidative stress and inflammation—and by inactivating harmful compounds we are exposed to on a daily basis.

We wouldn't state it in such bold terms. The Fountain of Youth has not yet been discovered.
However, the high level of sulforaphane in BROQ does affect factors closely tied to aging:

(1) Oxidative stress is strongly associated with aging. (Source) Sulforaphane is the most potent natural molecule that actives NRF2, which reduces oxidative stress. (Source)

(2) Inflammation is the single most important driver of human aging. Virtually all people who live to be 100 have very low inflammation.​ Sulforaphane has been shown, in multiple studies, to significantly reduce markers of inflammation, such as C-reactive protein and IL-6. (See sources here.)

(3) Autophagy is the body’s way of cleaning out damaged cells to make way for new ones.​ “Auto” means self and “phagy” means eat; so, literally, the word describes cells eating themselves. ​Autophagy is the primary source of the many health benefits of fasting.​ Sulforaphane has been shown to promote autophagy (without fasting). (See sources here.)

Scientific interest in sulforaphane has exploded in recent years, as shown in the chart below (Pubmed articles about sulforaphane, by year)

Sulforaphane is now one of the most actively studied dietary compounds in existence.

New findings about sulforaphane are being published regularly.


One serving of BROQ is two capsules, which contain a total of 20mg of sulforaphane.

Many studies have found significant benefits from this amount of sulforaphane.

A number of studies used a daily dosage of 60mg of sulforaphane, the equivalent of six capsules of BROQ.

Those studies found substantial benefits without any notable adverse effects.

We recommend taking BROQ with meals, to avoid minor stomach discomfort that might occur otherwise.

If you're taking more than two capsules daily, split the dosage across meals.

Time of day is not important.

BROQ contains highly bioactive sulforaphane. (The word "bioactive" simply means that the sulforaphane will enter circulation in your body.)

To maintain full potency, keep refrigerated after opening.

Keep BROQ away from heat sources and prolonged direct sunlight.


(1) BROQ delivers more than double the amount of bioavailable sulforaphane per serving of any other supplement.

(2) BROQ is one of only two supplements that contain sulforaphane. All others contain compounds that must be converted to sulforaphane in the body. (The other supplement containing sulforaphane is BrocElite™.)

(3) The sulforaphane in BROQ is stabilized using a patented process that took 15 years to develop.

(4) BROQ (under its European brand name, Prostaphane®), has been extensively studied. This is not true of BrocElite™.

On our Product Comparison page, we present an in-depth comparison of the top 30 sulforaphane supplements available in the US.

All supplements were tested by this independent lab, which is a division of this company. You can view images of the certified test results by clicking on any product image on the Product comparison page.

All products were purchased on Amazon in December, 2020.

On our label, we promise to deliver 20mg of sulforaphane per serving.​

We produce BROQ with about 30% more than that amount—around 26mg. (This is confirmed by the independent lab results.)​

The reason for this is that the sulforaphane content may decrease over time, especially if the product is exposed to heat.​

Keeping BROQ refrigerated will help minimize decline in potency.

One word: bioavailability.

The sulforaphane in BROQ is 70% bioavailable, meaning that the expected amount of sulforaphane that will enter circulation in your body after you take one serving is 70% of what the capsules contain.

When you take a supplement containing precursors, bioavailability will be 30% (if it contains the enzyme myrosinase) or 10% (if it doesn't contain myrosinase).

The sulforaphane in BROQ is fully stable when kept refrigerated.

At room temperature, the level of sulforaphane may decrease by around 2% per month.

At temperatures above 78 degrees Fahrenheit, it may decrease by 4% or more per month.

Note that BROQ is manufactured with 20-30% more sulforaphane per serving than shown on the label.


We produce each capsule of BROQ to contain 20-30% more sulforaphane than shown on the label.

Even when shipped during hot summer months, the rate of decline in sulforaphane dosage should be under 5% per month (while exposed to heat).

Shipping time of 1 to 4 days, even during summer heat, should have minimal impact—less than 1%.

You'll still be getting even more sulforaphane than shown on the label.
