FormulaForge carries a single form of Broccoli Seed Extract (13% Glucoraphanin), so there is no form to choose here. Forms on the market do differ in how well they absorb, which is why it is worth checking the form named on any product label.

TrueBroc® SGS Broccoli Seed Extract (13% Glucoraphanin) Preferred (Preferred Form) has a bioavailability rating of good absorption.

TrueBroc is a patented broccoli seed extract standardized to 13% glucoraphanin, the precursor to sulforaphane. Sulforaphane is one of the most potent natural activators of the Nrf2 pathway, which governs cellular antioxidant and detoxification defenses. Research supports its role in liver health, inflammatory response, and cellular protection.

In a randomized double-blind crossover (n=16), glucoraphanin co-delivered with myrosinase doubled sulforaphane bioavailability (39.8% vs 18.6%) measured by urinary metabolites. PMID: 41692762

In a human crossover, sulforaphane plasma/urinary bioavailability was dramatically lower from a myrosinase-inactive broccoli supplement than from fresh sprouts. PMID: 21816223

Human subjects (200 umol SFN/day) showed ~3x higher sulforaphane plasma/urinary metabolite levels from fresh sprouts than from a broccoli sprout extract. PMID: 25522265
