Benefits And Science

Sulforaphane metabolites concentrate in urine, making the bladder unusually exposed. What the animal and enzyme-induction research actually found.

Broccoli sprout extract has been tested against pollen and diesel exhaust in human nasal challenge studies. Here is what those trials found.

Three human trials tested sulforaphane in men with prostate cancer concerns. What they measured, and what the PSA doubling time results actually mean.

What three randomized trials in Qidong, China found about broccoli sprout beverages and the body’s excretion of benzene and acrolein.

A decade of University of East Anglia work took sulforaphane from cartilage cells to mice to a human broccoli trial. Here is what each stage found.

What the sperm quality research shows: human samples tested outside the body, animal models of diet-induced infertility, and livestock breeding data.

The preclinical research on sulforaphane, Nrf2 activation, and oxidative eye damage linked to cataracts and age-related macular degeneration.

What preclinical models and one early human trial show about sulforaphane, Nrf2 activation, and kidney protection in chronic and acute kidney injury.

Beyond asthma: the COPD rationale, and why the key randomized trial matters specifically because it returned a negative result in a well run study.

A randomized trial tested broccoli sprout extract in people with type 2 diabetes. What it measured, what it found, and the limits that remain.

Sulforaphane’s gut link runs both ways. Bacteria help convert it, and it appears to shift microbiome composition and barrier function in return.

What the Nrf2 pathway means for skin: how sulforaphane is studied for UV damage and photoaging, and where the human evidence currently stops.
