The Claim

Oral sulforaphane supplementation at 120 μmol/day for 12 months was not associated with severe adverse events in former smokers with a history of heavy smoking.

In plain English

Taking 120 micromoles of sulforaphane daily for one year did not lead to severe side effects in former heavy smokers.

See the scientific wording

Oral sulforaphane supplementation at 120 μmol/day for 12 months was not associated with severe adverse events in former smokers with a history of heavy smoking, suggesting a favorable short-term safety profile.

Why this might work

Sulforaphane enters the body through the gut, travels to the lungs, and turns on a natural defense system that cleans up harmful chemicals and repairs damaged cells. This system reduces the number of damaged cells that could become cancerous, without causing serious harm to the body.

    This study gave former heavy smokers a daily sulforaphane pill for a year and found no serious side effects, which means it’s likely safe to take for that long.
