What does Rhonda Patrick say about Sulforaphane?

Rhonda Patrick describes sulforaphane as a plant compound that activates protective stress-response and detoxification pathways, with evidence suggesting benefits for antioxidant defenses in the brain and vascular system. 1

• Broccoli sprouts: They can contain up to 100 times more sulforaphane than broccoli, and human evidence indicates they can activate glutathione in the brain. 2
• Mustard seed powder: Cooking lowers broccoli’s sulforaphane because heat-sensitive myrosinase helps form it; adding one gram of ground mustard seed powder to cooked broccoli was shown to raise sulforaphane fourfold. 3
• Detoxification and DNA damage: Patrick describes human findings in which broccoli sprout extract lowered DNA damage in white blood cells and increased urinary excretion of benzene and acrylene after 24 hours. 4
• Ischemic stroke: Animal studies suggest that sulforaphane given beforehand primes stress-response pathways and improves outcomes after an induced ischemic stroke; Patrick emphasizes these are animal findings. 5
• Protective pathways and diet: Sulforaphane activates NRF2 and pathways linked to glutathione, antioxidant and anti-inflammatory responses, and autophagy. Patrick also cautions against sweeping, sensational claims about plants, noting that toxicity depends on the plant and exposure. 6 7
