What is Sulforaphane?
There is a substance called sulforaphane (also called SFN) found in cruciferous vegetables and especially in broccoli sprouts. It is well studied to be anticancer, antimicrobial, anti-inflammatory, neuroprotective, and may even protect against aging and diabetes. The best part? We don’t need high-priced supplements to get this important phytochemical, we just need to eat certain veggies like broccoli sprouts.
Sulforaphane is created when the enzyme myrosinase transforms the glucosinolate glucoraphanin into sulforaphane. Since myrosinase and glucoraphanin are found in different parts of the plant, this change happens when the plant is damaged (by chewing, blending, chopping, etc.) allowing the two compounds to mix and react. Young sprouts of broccoli and cauliflower are particularly good sources of glucoraphanin.
More specifically, sulforaphane is part of a group of plant-based disease-fighting phytochemicals called isothiocyanates. In the body, sulforaphane stimulates the production of important enzymes that neutralize free radicals. Since inflammation and free radicals get the blame for many types of cancer, this is a big deal. Isothiocyanates also seem to block certain cancer-activating enzymes in the body, creating a double protection.
Befenits of sulforaphane
Sulforaphane is found in cruciferous vegetables including broccoli, cauliflower, Brussels sprouts, cabbage, collards, kale, bok choy, kohlrabi, turnip, collards, arugula, watercress, radish, and mustard greens. Broccoli sprouts have the highest identified concentration of sulforaphane.
All green veggies serve an important purpose and you’ll have a hard time finding any doctor or health expert who would say eating green veggies is not a good idea (short of very specific health conditions).
Most of the sulforaphane you’ll find online requires activation by gut bacteria that aren’t common, so you probably won’t see much benefit from it. You can either buy an enzyme-activated sulforaphane or make sure to eat a bite of raw radish or cruciferous vegetable (like a broccoli stalk) to get the right living enzymes in your gut to activate the supplement.
Recommended dose: 10 mg sulforaphane daily with some raw cruciferous vegetable or raw radish or 10 mg of an enzyme-activated sulforaphane supplement.
Time of day: Anytime, on an empty stomach.
