Dietary Interventions, Supplements, and Plant-Derived Compounds for Adjunct Vitiligo Management: A Review of the Literature

Vitiligo is a chronic autoimmune pigmentation disorder shaped by a complex interplay of genetic predispositions and environmental triggers. While conventional therapies—phototherapy, corticosteroids, and immunosuppressants—can be effective, their benefits are often partial and temporary, with recurrence common once treatment stops. As such, there is increasing interest in exploring complementary approaches that may offer a more sustainable impact. Emerging evidence suggests that macronutrient and micronutrient-level changes could be beneficial for managing progression and, in some cases, facilitating repigmentation. Antioxidant-rich foods, such as apples, green tea, Indian gooseberry, onions, and peppers, may help mitigate oxidative stress, while inflammatory foods, such as gluten and high-phenol nuts and berries, may exacerbate the condition. Certain supplements, including high-dose vitamin D, vitamin C, vitamin E, and selenium, may enhance phototherapy outcomes. Omega-3 and other unsaturated fatty acids, in addition to prebiotics and probiotics, are under active investigation for their roles in gut health and immune regulation. Notably, plant-derived compounds, i.e., Ginkgo biloba, have demonstrated promise in promoting repigmentation and managing disease progression. However, it must be emphasized that these nutritional interventions remain exploratory, and more research is needed to establish their efficacy, safety, and optimal usage before they can be recommended as part of a standard treatment regimen.
