Sulforaphane is a bioactive compound found in cruciferous vegetables like broccoli, and it has been investigated for its potential role in supporting or treating Inflammatory Bowel Disorders (IBD), such as Crohn's disease and ulcerative colitis. The scientific rationale for its use centers on sulforaphane’s well-documented antioxidant and anti-inflammatory properties. Preclinical studies—primarily in animal models and cell cultures—have demonstrated that sulforaphane can inhibit nuclear factor kappa B (NF-κB) signaling, a pathway known to drive inflammation in IBD. It also upregulates phase II detoxification enzymes and augments the body's endogenous antioxidant defenses, which may help mitigate oxidative stress associated with intestinal inflammation.

However, clinical evidence in humans is very limited. Most of the support comes from mechanistic studies and animal research, with only a few small-scale human studies or case reports suggesting potential benefits. There are no large randomized controlled trials conclusively demonstrating efficacy or establishing optimal dosing in IBD patients. Thus, while scientific interest exists, and the mechanism is plausible, the overall evidence supporting the use of sulforaphane for IBD is preliminary and insufficient to warrant strong recommendations. More robust clinical trials are needed to clarify its therapeutic potential in this context.
