Sulforaphane testing starts with product chemistry and diet context, because ingredient metadata decides whether the label likely matches the biology.
Methodology
This protocol evaluates glucoraphanin, sulforaphane, myrosinase presence, diet overlap, tolerability, and measurable endpoints. It avoids cancer-treatment, autism-treatment, and detox cure claims.
| Product question | Why it matters |
|---|---|
| Is it sulforaphane or glucoraphanin | Different label meaning |
| Is myrosinase present | Conversion can change exposure |
| Is the dose stated clearly | Hidden sprout blends are hard to test |
| Is diet stable | Cruciferous vegetables confound the trial |
| Is the endpoint realistic | Most home markers are indirect |
Protocol
| Phase | Rule |
|---|---|
| Baseline | 14 days with stable cruciferous vegetable intake |
| Active | 4-8 weeks with one product |
| Endpoint | GI tolerance, sleep, skin notes, optional clinician labs |
| Do not change | Broccoli sprouts, crucifer intake, new antioxidants |
| Stop | Severe GI symptoms, rash, medication concern |
Safety notes
People using thyroid medication, anticoagulants, chemotherapy, psychiatric medication, or complex medical care should get clinician review. Sulforaphane research is interesting, but broad disease claims are not a home testing plan.
