Sulforaphane from Broccoli Sprout Extract is a vegetarian capsule supplement from Swanson GreenFoods Formulas, delivering 400mcg of sulforaphane per capsule across 60 vcaps. The active ingredient is sourced from BroccoPhane, a 20:1 broccoli sprout concentrate standardised to 0.4% sulforaphane — the naturally occurring compound found in cruciferous vegetables, particularly broccoli sprouts.
Broccoli sprouts contain notably higher concentrations of sulforaphane than mature broccoli, making an extract format a straightforward way to obtain the compound without relying on large quantities of fresh produce. Each veggie capsule is suitable for those following a vegetarian or vegan diet, and the capsule format keeps things simple whether taken at home or at work.
Swanson’s GreenFoods range is built around standardised botanical extracts, with guaranteed potency levels confirmed at the point of manufacture. This product appeals to health-conscious individuals, those following plant-rich diets, and anyone with a particular interest in broccoli-derived compounds as part of their broader wellness routine.
