The latest test result showed 0.607% (w/w) of sulforaphane in a 100 g sample of our broccoli powder- meaning- 0.607 g in 100 g of sample, or 0.00607g of sulforaphane in 1 g of powder. But in our company experience, sulforaphane content can be anywhere from 0.5 grams to 1.5 grams per 100 grams of broccoli sprouts powder (depending on the lot).
