The Claim

Compliance with sulforaphane supplementation is associated with a statistically significant dose-dependent reduction in the bronchial Ki-67 index.

Source: Abstract 749: Randomized placebo-controlled phase II clinical trial on oral supplementation of sulforaphane for 12 months that reduced bronchial Ki-67 index in former smokers at high risk for lung cancer

In plain English

Higher adherence to sulforaphane supplements is linked to a measurable decrease in the Ki-67 marker in bronchial tissue, which indicates reduced cell proliferation.

See the scientific wording

There was a statistically significant dose-response relationship between sulforaphane supplement compliance and reduction in bronchial Ki-67 index, suggesting that adherence to the regimen enhances the biological effect.

Why this might work

Sulforaphane enters cells in the airways and turns on a protective system that cleans up harmful chemicals and reduces damage to DNA. This causes the cells to stop multiplying abnormally, which lowers the number of cells showing signs of uncontrolled growth.

    People who took the sulforaphane supplement more regularly had a bigger drop in a marker of abnormal cell growth in their airways, meaning taking it consistently made it work better.
