Moderate Consensus

Based on 28 videos (39 hours analyzed) across the experts · Updated 2026-03-23
Expert Positions
The Verdict
3 of 5 experts actively discuss sulforaphane, with Patrick being the dominant authority. Patrick has dedicated multiple videos to sulforaphane's Nrf2 activation, cancer prevention, and detoxification benefits, and personally consumes broccoli sprouts daily. Huberman covers sulforaphane through guest episodes with Patrick, endorsing it for detoxification and liver support. Hyman references sulforaphane frequently as a phytochemical within broader food-as-medicine discussions. Attia and Johnson have no direct sulforaphane coverage in analyzed videos.
Where They Disagree
Patrick is significantly more bullish on supplemental sulforaphane than the other experts. She dedicates entire episodes to the compound and personally takes broccoli sprouts daily, while Hyman and Huberman discuss it as one beneficial phytochemical among many.
There is a food-vs-supplement divide: Patrick and Fahey emphasize that broccoli sprouts are the ideal source but acknowledge supplements can work if they contain both glucoraphanin and myrosinase. Hyman consistently frames sulforaphane benefits through whole cruciferous vegetable consumption rather than isolated supplementation.

About This Analysis
This consensus report on Sulforaphane is based on 28 videos (39 hours analyzed) from five longevity experts: Andrew Huberman, Peter Attia, Rhonda Patrick, Bryan Johnson, and Mark Hyman. Each expert's position was independently analyzed from their published video content, including lectures, podcast episodes, and Q&A sessions with 1,000+ guest scientists.
The full report includes 8 key findings, dosage and protocol details, expert deep dives with direct video citations and timestamps, risk considerations, and related supplement synergies.
Frequently Asked Questions
How much sulforaphane should you take per day?
Dr. Jed Fahey (via Patrick) puts the daily target at 50-100 micromoles of sulforaphane — roughly 50-100g of fresh broccoli sprouts. Actual content varies significantly by genetics, growing conditions, and preparation method. Patrick doesn't fix a pill dose; she gets hers from broccoli sprouts in her morning micronutrient smoothie.
Broccoli sprouts vs sulforaphane supplement — which is better?
Patrick and Fahey favor fresh broccoli sprouts, which contain 20-100x more glucoraphanin (the sulforaphane precursor) than mature broccoli. Supplements can work, but quality varies enormously — many contain glucoraphanin without active myrosinase, the enzyme needed to convert it. Choose products with both. Hyman frames benefits through whole cruciferous vegetables rather than isolated pills.
Does sulforaphane help with detox?
Yes. Huberman recommends sulforaphane for phase two liver detoxification to help excrete endocrine-disrupting chemicals from microplastic exposure. Patrick cites increased excretion of carcinogens like benzene through Nrf2-mediated detoxification, and Hyman notes it upregulates enzymes that let glutathione bind toxins for excretion. It also boosts glutathione in both the brain and plasma.
What does sulforaphane do in the body (Nrf2)?
Patrick calls sulforaphane the most potent natural activator of the Nrf2 pathway, which regulates over 200 genes involved in antioxidant defense, detoxification, and anti-inflammatory response. Through Nrf2 it boosts glutathione and helps excrete carcinogens. Patrick also links the top 20% of cruciferous consumers to a 22% reduction in all-cause mortality.
How do you get the most sulforaphane from broccoli?
Myrosinase — the enzyme that converts glucoraphanin to sulforaphane — is heat-sensitive, so overcooking destroys it. Patrick's fixes: eat raw or lightly steamed, heat broccoli sprouts to exactly 70C for 10 minutes (deactivating the epithiospecifier protein and tripling yield), or add mustard seed powder after cooking to restore myrosinase and boost bioavailability up to 4-fold.
