Sulforaphane: The Best Sources

Sulforaphane: The Best Sources

Sulforaphane is a remarkable phytonutrient found in cruciferous vegetables. This compound supports the body to produce its own natural antioxidants, including Glutathione. These natural antioxidants help protect your body and cells from oxidative stress, air pollutants, UV radiation, toxins, hormone imbalance and other stresses, enhancing your overall health.

While Sulforaphane is present in various cruciferous vegetables, not all sources are created equal in terms of potency and bioavailability. Here's a rundown of some popular options:

Broccoli Sprouts

Broccoli sprouts have gained popularity as one of the richest sources of Sulforaphane. They contain concentrated levels of Glucoraphanin, a precursor to Sulforaphane. When chewed or chopped, an enzyme called myrosinase converts Glucoraphanin into Sulforaphane, maximising its bioavailability. Incorporating broccoli sprouts into salads, sandwiches, or smoothies is an excellent way to reap the benefits of Sulforaphane.


Broccoli florets are another excellent source of Sulforaphane. While not as potent as broccoli sprouts, broccoli still contains significant levels of Glucoraphanin. To enhance Sulforaphane production, it's advisable to lightly steam or sauté broccoli rather than boiling it, as excessive heat can destroy the myrosinase enzyme.

Other Cruciferous Vegetables

While broccoli and broccoli sprouts steal the spotlight, other cruciferous vegetables like brussels sprouts, cauliflower, kale, and cabbage also contain varying amounts of Sulforaphane. Incorporating a diverse range of these vegetables into your diet ensures a broader spectrum of nutrients and phytochemicals. 

FourHealth Green+ is made from three-day-old broccoli sprouts, ensuring optimal potency and bioavailability. With a high concentration of Sulforaphane (over 7-9 mg per capsule!), Green+ is one of the highest yielding broccoli supplements of its kind. Plus, we pair Sulforaphane with the mineral Selenium, providing both indirect and direct antioxidant benefits for optimal health and wellbeing.

Sulforaphane holds immense promise as a potent bioactive compound with numerous health benefits. While broccoli sprouts stand out as a concentrated source, incorporating a variety of cruciferous vegetables into your diet ensures a steady intake of Sulforaphane and other essential nutrients. Whether you opt for fresh produce, sprouts, or supplements, prioritising these nutrient-rich foods can help unlock the potential benefits of Sulforaphane and support overall well-being.

Remember, moderation and variety are key in any healthy diet. So, why not savour the flavours and reap the rewards of Sulforaphane-rich foods? Your body will thank you for it!
