Title: Protective Effects of Sulforaphane Preventing Inflammation and Oxidative Stress to Enhance Metabolic Health: A Narrative Review
Journal: Nutrients (MDPI)
Year: 2025
This recent review published in Nutrients (2025) comprehensively summarizes how sulforaphane (SFN) contributes to metabolic health by activating the Nrf2 pathway, suppressing inflammation and oxidative stress, and supporting immune balance.
It provides clear evidence of SFNโs anti-inflammatory and immune-protective roles, making it highly relevant for immune function research and health communication.
๐ฌ Mechanisms and Actions
| Mechanism | Description |
|---|---|
| Activation of the Nrf2 Pathway | Sulforaphane activates Nrf2, promoting the expression of antioxidant genes (e.g., HO-1, NQO1) and reducing oxidative stress. |
| Inhibition of NF-ฮบB Signaling | Suppresses NF-ฮบB, a key inflammatory pathway, leading to decreased secretion of pro-inflammatory cytokines such as TNF-ฮฑ and IL-6. |
| Regulation of Immune Cell Function | Modulates macrophage activity, balances NK cell response, and regulates Th17/Treg ratio to maintain immune homeostasis. |
๐ก Key Summary
Sulforaphane acts as a โsmartโ anti-inflammatory compound, regulating imbalanced immune responses without overstimulating immune activity.
By activating the Nrf2 pathway, it enhances antioxidant enzyme expression and protects cells from oxidative damage.
Simultaneously, NF-ฮบB inhibition contributes to systemic inflammation reduction and metabolic disorder improvement โ including conditions such as obesity and diabetes.
