Glucoraphanin is a glucosinolate found in broccoli[1] and cauliflower,[2] in particular in the young sprouts. When these foods are consumed, the enzyme myrosinase transforms glucoraphanin into raphanin, which is an antibiotic, and into sulforaphane, which exhibits anti-cancer and antimicrobial properties in experimental models. Preliminary research also suggests that glucoraphanin may slow and prevent arthritis,[3] and 'retune' mitochondrial metabolism.[4] A variety of broccoli has been bred to reliably contain 2-3 times more glucoraphanin than standard broccoli.[5][6] Consumption of large amounts of glucoraphanin may produce negative effects due to increased creation of reactive oxygen species.[7] However, this is based on studies on rats fed pure glucoraphanin at a dose equivalent to a human consuming approximately 250 portions of broccoli per day. Other studies have shown glucoraphanin to be safe, even at doses far higher than would be obtained through eating broccoli.[8]
