When to Take Sulforaphane — Expert Timing Protocols
Expert-analyzed timing recommendations for sulforaphane based on what 5 longevity researchers say about when, how, and what to take it with.
Quick Timing Guide
No specific timing recommendations emerged from the expert discussions. Patrick includes sulforaphane-rich foods in her morning smoothie. For cooked cruciferous vegetables, add mustard seed powder after cooking to restore myrosinase activity and maximize conversion.

Timing
No specific timing recommendations emerged from the expert discussions. Patrick includes sulforaphane-rich foods in her morning smoothie. For cooked cruciferous vegetables, add mustard seed powder after cooking to restore myrosinase activity and maximize conversion.
Dosage
50-100 micromoles of sulforaphane daily. This is roughly equivalent to 50-100g of fresh broccoli sprouts, though actual content varies significantly by genetics, growing conditions, and preparation method (Fahey via Patrick).
Form
Fresh broccoli sprouts are the preferred source — Patrick grows and consumes them daily in her micronutrient smoothie. For supplements, choose products containing glucoraphanin with myrosinase (the enzyme required for conversion). Patrick and Fahey emphasize that supplement quality varies enormously. Whole food sources are preferred over supplements when possible.
Notes
Myrosinase is heat-sensitive — overcooking cruciferous vegetables destroys the enzyme needed to convert glucoraphanin to sulforaphane. Options to preserve or restore myrosinase: (1) eat raw or lightly steamed, (2) heat broccoli sprouts to exactly 70C for 10 minutes, (3) add mustard seed powder after cooking. The gut microbiome can also convert some glucoraphanin to sulforaphane even without myrosinase, but this is less efficient and varies by individual.

Important Notes
Myrosinase is heat-sensitive — overcooking cruciferous vegetables destroys the enzyme needed to convert glucoraphanin to sulforaphane. Options to preserve or restore myrosinase: (1) eat raw or lightly steamed, (2) heat broccoli sprouts to exactly 70C for 10 minutes, (3) add mustard seed powder after cooking. The gut microbiome can also convert some glucoraphanin to sulforaphane even without myrosinase, but this is less efficient and varies by individual.
Where Experts 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.
- Hyman discusses sulforaphane primarily as part of a detoxification and cancer prevention framework, while Patrick covers a broader range of benefits including cardiovascular health, brain health, autism spectrum disorder, and depression.
