This product’s label serving is 2 beadlets daily, providing 50 mg of active sulforaphane.
A 2025 randomized, double-blind, placebo-controlled trial in 74 adults with prediabetes tested a broccoli sprout extract providing about 150 μmol (roughly 27 mg) of sulforaphane daily for 12 weeks — about half this product’s dose. The trial’s primary endpoint (a 0.3 mmol/L reduction in fasting glucose) was not met; the overall effect across all participants was a smaller 0.2 mmol/L reduction, though a subgroup with mild obesity and specific gut bacteria showed a stronger response [1]. We’re citing this study for its honesty about missing its own primary endpoint, not because it proves this product’s higher dose works better.
As with the other calculators on our network, there’s no published bodyweight-adjusted dosing for sulforaphane, so this tool plans by a fixed daily amount rather than your height or weight.
