Sulforaphane is a natural substance found in cruciferous vegetables. It has been studied as an anti-cancer agent. It appears to induce enzymes that deactivate free radicals and carcinogens, enhancing the body’s defense against chemicals that cause cancer.
One article (1) looked at Sulforaphane and its treatment of cancer. It noted that cruciferous vegetables have been studied and have been found to be effective against various types of cancer. Certain cruciferous vegetables contain glucoraphanin, which is a precursor to sulforaphane.
The article reported that several studies support the protective effects of taking in sulforaphane and the treatment of cancer. It noted that sulforaphane has an adverse effect on cancer stem cells, which are the precursor molecules against cancer.
