Thorne Broccoli Seed Extract, 60 Capsules
UPC: 693749660019
Thorne's Broccoli Seed Extract is formulated to support liver detoxification and provide long-lasting antioxidant protection by activating the body's natural antioxidants like glutathione. It combines sulforaphane glucosinolate (SGS) from broccoli and kale seed extracts with myrosinase from mustard seeds, enhanced by vitamin C to optimize bioavailability; the manufacturer notes this formula is equivalent to eating two pounds of cruciferous vegetables per capsule.
This product stands out for its inclusion of myrosinase, an enzyme that helps convert SGS into its active form, sulforaphane, which is supported by research on bioavailability. Thorne emphasizes third-party testing for label accuracy and contaminants, and it is manufactured in the USA. Available in a 60-capsule bottle, it comes in a vegetarian capsule form with calcium laurate as an excipient.
