Preliminary / mechanistic evidence
Evidence summary & quality
Biologically plausible pathway; goal-specific human outcome evidence not reviewed
Evidence applies to a specific ingredient, form, population and outcome—not automatically to this product.
Relevant studied outcomes
Glucoraphanin and sulforaphane are research targets; a longevity or whole-body clinical benefit is not established here.
How it might work
Glucoraphanin can convert to sulforaphane through myrosinase, with conversion varying between people and products.
Important limitation
Mechanistic plausibility and biomarker changes do not prove longer life or better cognitive function.
Typical investigated dose / label context
No comparable goal-specific dose reviewed. Glucoraphanin, sulforaphane and myrosinase units are not interchangeable measures.
Not dosing advice. Do not start, stop or change a supplement based on this summary. Confirm suitability and total intake with a qualified healthcare professional.
Safety & interactions. Product-specific safety, thyroid concerns, allergies and medicine interactions should be reviewed, especially with concentrated extracts.
Questions to ask a clinician or pharmacist
- Does this product provide glucoraphanin, sulforaphane or active myrosinase, and how does that affect interpretation?
- Is the studied ingredient form and amount comparable with this label?
- Could this interact with my medicines, health conditions, pregnancy, nursing, or planned surgery?
- What would we use to judge benefit, and when should I stop or seek advice?

PubMed · Research search — not a specific paper or verified citation
What it is
A source of glucoraphanin, which converts to sulforaphane via the enzyme myrosinase.
What to compare
- Glucoraphanin vs. stabilized sulforaphane content
- Presence of active myrosinase (pairs with mustard seed block)
- Independent third-party testing (identity, potency, heavy metals, microbes)
- Cost per matching active mg, not per capsule
- Tolerability and known side effects at this dose
Evidence grade: Less established
Conversion to sulforaphane varies widely between people and products; human outcome data are limited. Grades are qualitative editorial summaries, not formal systematic reviews.
