If sulforaphane is this well-researched, why isn't every gastroenterologist recommending it?
Three reasons — and the third one is the most important.
1. There's no pharmaceutical profit in broccoli.
Sulforaphane can't be patented. No drug company is going to spend $500 million on clinical trials for a compound they can't own. So the research exists — published in top journals, conducted at one of the world's best medical institutions — but no one has the marketing budget to put it in front of your doctor.
2. You can't eat enough broccoli sprouts to match the clinical doses.
The Johns Hopkins study used extract equivalent to roughly 2 pounds of fresh broccoli sprouts daily. Even the most committed health enthusiast isn't sustaining that for 8 weeks straight. And cooking destroys the key enzyme. Raw sprouts lose potency within hours of harvest. The logistics don't work for most people.
3. Most "sulforaphane" supplements don't actually produce sulforaphane.
This is the critical part.
Sulforaphane doesn't exist inside the capsule. It has to be created through an enzymatic reaction between two components: glucoraphanin (the precursor) and myrosinase (the enzyme).
Without myrosinase, glucoraphanin sits in your gut and does nothing. It passes through unactivated. No sulforaphane is produced. No Nrf2 activation. No repair.
And here's the problem: the vast majority of broccoli supplements on the market contain only glucoraphanin without myrosinase. They're selling you the locked vault without the key.
This is why someone can try a broccoli sprout supplement from Amazon, get zero results, and conclude that "sulforaphane doesn't work." It's not that sulforaphane doesn't work. It's that their supplement never produced any.
"I tried a sulforaphane supplement for 3 months and nothing changed. Maybe broccoli sprouts just don't work after all." — Common sentiment in H. pylori forums
What actually happened: the product was missing myrosinase. No conversion. No sulforaphane. No results.
